    Qwest Capital Funding, Inc. (formerly U S WEST Capital Funding, Inc.) (the
"Company" or "Capital Funding," which may be referred to as "we," "us," or
"our") hereby offers, upon the terms and subject to the conditions set forth in
this prospectus and the accompanying letter of transmittal (which together
constitute the "exchange offer"), to exchange up to $2,250,000,000 aggregate
principal amount of our new 7.25% Notes due 2011 (the "new 7.25% Notes"), which
have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), for a like principal amount of our outstanding 7.25% Notes
due 2011 (the "old 7.25% Notes" and collectively with the new 7.25% Notes, the
"7.25% Notes"), which have not been so registered, and to exchange up to
$1,000,000,000 aggregate principal amount of our new 7.75% Notes due 2031 (the
"new 7.75% Notes"), which have been registered under the Securities Act, for a
like principal amount of our outstanding 7.75% Notes due 2031 (the "old 7.75%

Notes (collectively, the "new Notes") are identical in all material respects to
the old 7.25% Notes and the old 7.75% Notes (collectively, the "old Notes"),
respectively, except for the absence of certain transfer restrictions relating

Notes, and will be issued pursuant to, and entitled to the benefits of, the same
Indenture that governs the old Notes.

withdrawn prior to 5:00 p.m., New York City time, on              , 2001 unless

or the new 7.75% Notes is anticipated. You should carefully review the Risk

                FORWARD-LOOKING INFORMATION MAY PROVE INACCURATE

    This prospectus contains or incorporates by reference financial projections,
synergy estimates and other "forward-looking statements" as that term is used in
federal securities laws about Qwest's and our financial condition results of
operations and business. These statements include, among others:

    - statements concerning the benefits that Qwest expects will result from its
      business activities and certain transactions Qwest has completed, such as
      increased revenues, decreased expenses and avoided expenses and
      expenditures; and

    - statements of Qwest's expectations, beliefs, future plans and strategies,
      anticipated developments and other matters that are not historical facts.

    These statements may be made expressly in this prospectus, or may be
incorporated by reference to other documents filed with the Securities and
Exchange Commission (the "SEC"). You can find many of these statements by
looking for words such as "believes," "expects" "anticipates," "estimates," or
similar expressions used in this prospectus or incorporated by reference in this
prospectus.

    These forward-looking statements are subject to numerous assumptions, risks
and uncertainties that may cause Qwest's and our actual results to be materially
different from any future results expressed or implied by Qwest and us in those
statements. The risks and uncertainties include those risks, uncertainties and
risk factors identified, among other places, under "Risk Factors" and under
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" in the documents incorporated by reference in this prospects.

    The most important facts that could prevent Qwest and us from achieving our
stated goals include the following:

    - intense competition in the communications services market;

    - changes in demand for Qwest's products and services;

    - dependence on new product development and acceleration of the deployment
      of advanced new services, such as broadband data, wireless and video
      services, which could require substantial expenditure of financial and
      other resources in excess of contemplated levels;

    - rapid and significant changes in technology and markets;

    - higher than anticipated employee levels, capital expenditures and
      operating expenses;

    - adverse changes in the regulatory or legislative environment affecting
      Qwest's business and delays in Qwest's ability to provide interLATA
      long-distance services in its 14-state local service territory;

    - failure to maintain rights of way; and

    - failure to achieve the projected synergies and financial results expected
      to result from the acquisition of U S WEST, Inc., ("Old U S WEST"), by
      Qwest on June 30, 2000 (the "Merger"), timely or at all, and difficulties
      in combining the operations of Qwest and Old U S WEST, which could affect
      our revenues, levels of expenses and operating results.

    Because the statements are subject to risks and uncertainties, actual
results may differ materially from those expressed or implied by the
forward-looking statements. Qwest and we caution you not to place undue reliance
on the statements, which speak only as of the date of this prospectus or, in the
case of documents incorporated by reference, the date of the document.

                                       1

    The cautionary statements contained or referred to in this section should be
considered in connection with any subsequent written or oral forward-looking
statements that Qwest or we or persons acting on their or our behalf may issue.
Neither Qwest nor we undertake any obligation to review or confirm analysts'
expectations or estimates or to release publicly any revisions to any
forward-looking statements to reflect events or circumstances after the date of
this prospectus or to reflect the occurrence of unanticipated events.

amount of new 7.75% Notes for each $1,000 principal amount of old 7.75% Notes.

    In connection with the sale of the old Notes, we entered into a Registration
Rights Agreement with the initial purchasers dated as of February 14, 2001 (the
"Registration Rights Agreement"),

                                       3

which grants the holders of the old Notes certain exchange and registration
rights. The exchange offer is intended to satisfy such exchange rights, which
terminate upon the consummation of the exchange offer.

    Based upon existing interpretations of the Securities Act by the Staff of
the SEC as set forth in several no-action letters to third parties, we believe
that the new Notes issued in the exchange offer may be offered for resale or
resold by holders without having to comply with the registration and prospectus
delivery requirements of the Securities Act, provided that:

    - the new Notes are acquired in the ordinary course of the holders' business
      and the holders have no arrangement with any person to engage in a
      distribution of new Notes, and

    - the holders are not "affiliates" of Qwest or us or broker-dealers who
      purchased old Notes directly from us to resell under Rule 144A or any
      other available exemption under the Securities Act.

    Each holder, other than a broker-dealer, must represent that it is not an
affiliate of us or Qwest, is acquiring the new Notes in the ordinary course of
its business, is not engaged in and does not intend to engage in a distribution
of the new Notes and has no arrangement to participate in a distribution of new
Notes. Each broker-dealer that receives new Notes for its own account in the
exchange offer must acknowledge that it will comply with the prospectus delivery
requirements of the Securities Act in connection with any resale of the new
Notes. Broker-dealers who acquired old Notes directly from us and not as a
result of market-making activities or other trading activities may not
participate in the exchange offer and must comply with the prospectus delivery
requirements of the Securities Act in order to resell the old Notes.

    We do not intend to seek our own no-action letter from the Staff of the SEC,
and there can be no assurance that the Staff would make a similar determination
with respect to the new Notes as it has in no-action letters to third-parties
referred to above.


                                            
EXPIRATION DATE..............................  The exchange offer will expire at 5:00 p.m.,

                                               or a later date and time to which we extend

INTEREST ON THE NEW NOTES AND THE OLD NOTES..  Interest on the new 7.25% Notes and the new
                                               7.75% Notes will accrue from the date of the
                                               original issuance of the old 7.25% Notes or
                                               the old 7.75% Notes, as applicable, or from
                                               the date of the last periodic payment of
                                               interest on the old 7.25% Notes or the old
                                               7.75% Notes, as applicable, whichever is
                                               later. No additional interest will be paid on
                                               the old Notes tendered and accepted for
                                               exchange. However, old Notes that are not
                                               tendered or accepted for exchange will
                                               continue to accrue interest.

                                               beneficially registered in the name of a
                                               broker, dealer, commercial bank, trust
                                               company or other nominee and who wishes to
                                               tender should contact such registered holder
                                               promptly and instruct such registered holder
                                               to tender on such beneficial owner's behalf.
                                               If such beneficial owner wishes to tender on

                                               owner must, before completing and executing
                                               the letter of transmittal and delivering its

                                               have no further obligation to register the

ISSUER.......................................  Qwest Capital Funding, Inc. (formerly U S
                                               WEST Capital Funding, Inc.), a Colorado
                                               corporation.

                                               Notes due 2011. $1,000,000,000 principal
                                               amount of new 7.75% Notes due 2031.

MATURITY.....................................  February 15, 2011, and February 15, 2031, as
                                               applicable.

INTEREST RATE................................  7.25% and 7.75%, as applicable, per annum,
                                               calculated using a 360-day year of twelve 30

INTEREST PAYMENT DATES.......................  Each February 15 and August 15 commencing
                                               August 15, 2001.

RANKING......................................  The new Notes will rank equally with all of
                                               our other unsecured and unsubordinated
                                               indebtedness. As of March 31, 2001, we had
                                               approximately $13 billion of debt
                                               outstanding, not including debt of Qwest's
                                               other subsidiaries.

                                               The Notes are obligations guaranteed by
                                               Qwest. Qwest is a holding company with no
                                               material assets other than the stock of its
                                               subsidiaries. Qwest's subsidiaries conduct
                                               substantially all of their respective
                                               operations and own substantially all of their
                                               respective assets at the subsidiary level. As
                                               a result, the Notes effectively rank junior
                                               to all existing and future debt, trade
                                               payables and other liabilities of Qwest's
                                               subsidiaries other than us.

OPTIONAL REDEMPTION..........................  We can redeem the Notes at any time at a
                                               redemption price determined as described
                                               under "DESCRIPTION OF NEW NOTES--Optional
                                               Redemption" on page 20.

    $128 million for Merger-related and other one-time charges, a benefit of
    $14 million for the increase in the market value of Global Crossing Ltd.
    financial instruments, a charge of $85 million on our marketable equity
    securities for other than temporary declines in value, and an extraordinary
    charge of $65 million related to the early retirement of debt. 2000 net loss
    includes a charge of $1.096 billion of Merger-related costs, a charge of
    $560 million on the decline in the market value of certain financial
    instruments and a net gain of $182 million on the sales of investments. 1999
    net income includes expenses of $282 million related to a terminated merger,
    a loss of $225 million on the sale of common stock and a charge of
    $34 million on the decline in the market value of derivative financial
    instruments. 1999 net income also includes $240 million for the cumulative
    effect of a change in accounting principle related to recognizing directory
    publishing revenues and expenses from the "deferred method" to the "point of
    publication method." 1998 net income includes expenses of $68 million
    associated with the June 12, 1998 separation of

                                       7

    Old U S WEST's former parent company into two independent companies and an
    asset impairment charge of $21 million. 1997 net income includes a
    $152 million regulatory charge related primarily to the 1997 Washington
    State Supreme Court ruling that upheld a Washington rate order, a gain of
    $32 million on the sale of Old U S WEST's one-seventh interest in Bell

    telephone exchanges and the current effect of $15 million from adopting
    Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting
    for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed
    Of." 1996 net income also includes a gain of $34 million for the cumulative
    effect of the adoption of SFAS No. 121.

(2) Earnings before interest, income taxes, depreciation and amortization
    ("EBITDA") does not include non-recurring and non-operating items such as
    Merger-related costs, asset write-offs and impairments, gains/losses on the
    sale of investments and fixed assets, changes in the market values of
    investments, one-time legal charges and sales of local telephone exchanges.
    EBITDA does not represent cash flow for the periods presented and should not
    be considered as an alternative to net earnings (loss) as an indicator of
    our operating performance or as an alternative to cash flows as a source of
    liquidity, and may not be comparable with EBITDA as defined by other
    companies.

                                  RISK FACTORS

    You should carefully consider the following discussion of risks, and the
other information included or incorporated by reference in this prospectus in
evaluating us and Qwest and our and their business before participating in the
exchange offer:

RISK FACTORS RELATED TO THE EXCHANGE

    Holders of old Notes who do not exchange their old Notes for new Notes will
continue to be subject to the restrictions on transfer of the old Notes, as set
forth in the legends on the old Notes. The old Notes may not be offered or sold
unless they are registered under the Securities Act or are exempt from
registration. See "THE EXCHANGE OFFER."

DIFFICULTIES IN COMBINING OPERATIONS AND REALIZING SYNERGIES

    Qwest expects that the Merger will result in certain benefits, including
operating efficiencies, cost savings, synergies and other benefits. Achieving
the benefits of the Merger will depend in part upon the integration of the
businesses of Old U S WEST and Qwest in an efficient manner, which Qwest
believes will require considerable effort. In addition, the consolidation of
operations has required and will continue to require substantial attention from
management. The diversion of management attention and any difficulties
encountered in the transition and integration process could have a material
adverse effect on the revenues, levels of expenses and operating results of the
combined company. No assurance can be given that the two companies will succeed
in integrating their operations in a timely manner or without encountering
significant difficulties or that the expected operating efficiencies, cost
savings, synergies and other benefits from such integration will be realized.
There can be no assurance that such integration efforts will not have a material
adverse effect on Qwest's ability to compete or will not materially affect its
ability to service its debt, including the Notes.

FUTURE PROVISION OF INTERLATA SERVICES

    In the 14-state territory where Qwest provides service as an incumbent local
exchange carrier, Qwest is permitted to provide interLATA services only upon
satisfaction of certain regulatory conditions primarily related to local
exchange telephone competition. These restrictions will be lifted on a
state-by-state basis following further proceedings in these states and at the
Federal Communications Commission (the "FCC"). Qwest expects to file, by the end
of 2001 or in the first quarter of 2002, applications with the FCC for authority
to enter the interLATA business in each of the 14 states in its local service
territory. Qwest expects to receive approval from the FCC within 90 days after
each such filing, and in any event by the end of the second quarter of 2002.
There can be no assurance that Qwest will obtain timely approval of these
applications. As a result of these restrictions on in-region interLATA services,
Qwest will not be able to offer a ubiquitous long-distance solution to those
customers requiring services both in and out of the region. This may materially
adversely impact Qwest's ability to achieve its targeted growth in national
accounts requiring these services. Even after elimination of the interLATA
restrictions, Qwest's long-distance operations will be subject to various
regulatory constraints, including the requirement that interLATA services be
offered through a subsidiary that is structurally separated from Qwest's local
exchange company. There can be no assurance that these regulations will not have
a material adverse effect on Qwest's ability to compete or will not materially
affect its ability to service its debt, including the Notes.

                                       9

QWEST IS DEPENDENT ON ITS SUBSIDIARIES FOR REPAYMENT OF DEBT

    The Notes are obligations guaranteed by Qwest. Qwest is a holding company
with no material assets other than the stock of its subsidiaries. Qwest conducts
substantially all of its operations and owns substantially all of its assets at
the subsidiary level. As a result, the Guarantees effectively will rank junior
to all existing and future debt, trade payables and other liabilities of Qwest's
subsidiaries other than us. The rights of Qwest, and hence the rights of its
creditors (including holders of the Notes through Qwest's guarantee of payment
of principal, premium, if any, and interest) to participate in any distribution
of assets of any subsidiary upon its liquidation or reorganization or otherwise
would be subject to the prior claims of the subsidiary's creditors, except to
the extent that claims of Qwest itself as a creditor of the subsidiary may be
recognized. After the payment of the subsidiary's liabilities, the subsidiary
may not have enough assets remaining to pay Qwest to permit its creditors,
including the holders of the Notes through the guarantees, to be paid.

                               THE EXCHANGE OFFER

PURPOSE OF THE EXCHANGE OFFER

    We originally issued and sold the old Notes on February 14, 2001 in an
offering exempt from registration under the Securities Act in reliance upon the
exemptions provided by Section 4(2), Rule 144A of the Securities Act.
Accordingly, the old Notes may not be transferred unless registered or unless an
exemption from the registration requirements of the Securities Act and
applicable state securities laws is available.

    As a condition to the sale of the old Notes, we, Qwest and the initial
purchasers of the old Notes (the "initial purchasers") entered into the
Registration Rights Agreement. In the Registration Rights Agreement, we agreed
that we would use our reasonable best efforts to:

    - file with the SEC a registration statement under the Securities Act with
      respect to the new Notes within 150 calendar days of February 14, 2001 (or
      by July 14, 2001);

    - cause a registration statement to be declared effective under the
      Securities Act within 210 calendar days after February 14, 2001 (or by
      September 12, 2001);

    - keep the exchange offer open for not less than 30 calendar days (or longer
      if required by applicable law) after the date that notice of the exchange
      offer is mailed to the holders of the old Notes; and

    - consummate the exchange offer within 240 calendar days of February 14,
      2001 (or by October 12, 2001).

    We have filed a copy of the Registration Rights Agreement as an exhibit to
the registration statement of which this prospectus is a part. The registration
statement satisfies certain of our obligations under the Registration Rights
Agreement.

TERMS OF THE EXCHANGE OFFER, PERIOD FOR TENDERING OLD NOTES

    This prospectus and the accompanying letter of transmittal together make up
the exchange offer. On the terms and subject to the conditions set forth in this
prospectus and the letter of transmittal, we will accept for exchange any old
7.25% Notes and any old 7.75% Notes that are properly tendered on or before the
expiration date unless they are withdrawn as permitted below. We will issue
$1,000 principal amount of new 7.25% Notes in exchange for each $1,000 principal
amount of outstanding old 7.25% Notes surrendered in the exchange offer and we
will issue $1,000 principal amount of new 7.75% Notes in exchange for each
$1,000 principal amount of outstanding old 7.75% notes surrendered in the
exchange offer. Holders of the old Notes may tender some or all of their old
Notes; however, old Notes may be exchanged only in integral multiples of $1,000.

                                       10

The form and terms of the new Notes are the same as the form and terms of the
old Notes except that the exchange will be registered under the Securities Act
and the new Notes will not bear legends restricting their transfer.

    The new 7.25% Notes and the new 7.75% Notes will evidence the same debt as
the old 7.25% Notes and the old 7.75% Notes, respectively, and will be issued
under the same indenture.

    The exchange offer is not conditioned upon any minimum principal amount of
old 7.25% Notes or old 7.75% Notes being tendered. As of the date of this
prospectus, an aggregate of $2,250,000,000 in principal amount of the old 7.25%
Notes is outstanding and an aggregate of $1,000,000,000 in principal amount of
the old 7.75% Notes is outstanding. This prospectus is first being sent on or
about              , 2001, to all holders of old Notes known to us.

    Holders of the old Notes do not have any appraisal or dissenters' rights
under the indenture in connection with the exchange offer.

    We may, at any time or from time to time, extend the period of time during
which the exchange offer is open and delay acceptance for exchange of any old
Notes by giving written notice of the extension to the holders as described
below. During the extension, all old Notes previously tendered will remain
subject to the exchange offer and may be accepted for exchange by us. Any old
Notes not accepted for exchange for any reason will be returned without expense
to the tendering holder as promptly as practicable after the expiration of the
exchange offer.

    We reserve the right to amend or terminate the exchange offer if any of the
conditions of the exchange offer are not met. The conditions of the exchange
offer are specified below under "--Conditions Of The Exchange Offer." We will
give written notice of any extension, amendment, nonacceptance or termination to
the holders of the old Notes as promptly as practicable. Any extension to be
issued by means of a press release or other public announcement will be issued
no later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled expiration date.

PROCEDURES FOR TENDERING OLD NOTES

    The tender of old 7.25% Notes or old 7.75% Notes by a holder as set forth
below and the acceptance by us will create a binding agreement between the
tendering holder and us upon the terms and subject to the conditions set forth
in this prospectus and in the accompanying letter of transmittal. Except as set
forth below, a holder who wishes to tender old 7.25% Notes or old 7.75% Notes
for exchange must send a completed and signed letter of transmittal, including
all other documents required by the letter of transmittal, to the exchange agent
at one of the addresses set forth below under "--Exchange Agent" on or before
the expiration date. In addition, either:

    - the exchange agent must receive before the expiration date certificates
      for the old 7.25% Notes or old 7.75% Notes, as applicable, along with the
      letter of transmittal;

    - the exchange agent must receive confirmation before the expiration date of
      a book-entry transfer of the old 7.25% Notes or old 7.75% Notes, as
      applicable, into the exchange agent's account at the DTC as described
      below; or

    - the holder must comply with the guaranteed delivery procedures described
      below.

    The method of delivery of old 7.25% Notes or old 7.75% Notes, letters of
transmittal and all other required documents, including delivery through DTC, is
at the election and risk of the holders. If the delivery is by mail, we
recommend that holders use registered mail, properly insured, with return
receipt requested. In all cases, holders should allow sufficient time to assure
timely delivery. Holders should not send letters of transmittal or old 7.25%
Notes or old 7.75% Notes to us.

                                       11

    Some beneficial ownership of old Notes is registered in the name of a
broker, dealer, commercial bank, trustee or other nominee. If one of those
beneficial owners wishes to tender, the beneficial owner should contact the
registered holder of the old Notes promptly and instruct the registered holder
to tender on the beneficial owner's behalf. If one of those beneficial owners
wishes to tender on its own behalf, then before completing and signing the
letter of transmittal and delivering its old Notes, the beneficial owner must
either register ownership of the old Notes in the beneficial owner's name or
obtain a properly completed power of attorney from the registered holder of old
Notes. The transfer of record ownership may take considerable time. If the
letter of transmittal is signed by a person other than the registered holder of
the old Notes, the old Notes must be endorsed or accompanied by appropriate
powers of attorney. In either case, the letter of transmittal must be signed
exactly as the name of the registered holder appears on the old Notes.

    Signatures on a letter of transmittal or a notice of withdrawal must be
guaranteed unless the old 7.25% Notes or old 7.75% Notes surrendered for
exchange are tendered:

    - by a registered holder of the old Notes who has not completed the box
      entitled "SPECIAL REGISTRATION INSTRUCTIONS" or "SPECIAL DELIVERY
      INSTRUCTIONS" on the letter of transmittal, or

    - for the account of a firm or other entity identified in Rule 17Ad-15 under
      the Exchange Act as an eligible guarantor institution. Eligible guarantor
      institutions include:

    - a member of a registered national securities exchange; or

    - a member of the National Association of Securities Dealers, Inc.; or

    - a commercial bank or trust company having an office or correspondent in
      the United States.

    If signatures on a letter of transmittal or a notice of withdrawal are
required to be guaranteed, the guarantees must be by an eligible guarantor
institution.

    If old Notes are registered in the name of a person other than a signer of
the letter of transmittal, the old Notes surrendered for exchange must be
endorsed by the registered holder with the signature guaranteed by an eligible
guarantor institution. Alternatively, the old Notes may be accompanied by a
written assignment, signed by the registered holder with the signature
guaranteed by an eligible guarantor institution.

    All questions as to the validity, form, eligibility, time of receipt and
acceptance of old Notes tendered for exchange will be determined by us in our
sole discretion, and our determination will be final and binding. We reserve the
absolute right to reject any tenders of any old Notes not properly tendered or
any old Notes whose acceptance might, in our judgment or the judgment of our
counsel, be unlawful. We also reserve the absolute right to waive any defects or
irregularities or conditions of the exchange offer as to any old Notes either
before or after the expiration date. The interpretation of the terms and
conditions of the exchange offer as to any old Notes either before or after the
expiration date by us will be final and binding on all parties. Unless waived,
any defects or irregularities in connection with tenders of old Notes for
exchange must be cured within a reasonable period of time as we will determine.
Neither we, Qwest, the exchange agent nor any other person will be under any
duty to give notification of any defect or irregularity with respect to any
tender of old Notes for exchange. Any old Notes received by the exchange agent
that are not properly tendered and as to which the defects or irregularities
have not been cured or waived will be returned by the exchange agent to the
tendering holders, unless otherwise provided in the letter of transmittal, as
soon as practicable.

    If the letter of transmittal or any old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a

                                       12

fiduciary or representative capacity, those persons should so indicate when
signing. Unless waived by us, those persons must submit proper evidence
satisfactory to us of their authority to act.

    By tendering, each holder will represent to us:

    - that it is not an "affiliate," as defined in Rule 405 of the Securities
      Act, of us or Qwest, or if it is an affiliate, it will comply with the
      registration and prospectus delivery requirements of the Securities Act to
      the extent applicable;

    - that it is not a broker-dealer tendering Registrable Securities (as
      defined in the Registration Rights Agreement described herein) acquired
      directly from us;

    - that it is acquiring the new 7.25% Notes or the new 7.75% Notes in the
      ordinary course of its business; and

    - at the time of the closing of the exchange offer it has no arrangement or
      understanding to participate in the distribution, within the meaning of
      the Securities Act, of the new 7.25% Notes or the new 7.75% Notes.

    If the holder is a broker-dealer that will receive new 7.25% Notes or new
7.75% Notes for its own account in exchange for old 7.25% Notes or old 7.75%
Notes that were acquired as a result of market-making activities or other
trading activities, the holder may be deemed to be an "underwriter" within the
meaning of the Securities Act. Such holder will be required to acknowledge in
the letter of transmittal that it will deliver a prospectus in connection with
any resale of the new 7.25% Notes or the new 7.75% Notes. However, by so
acknowledging and by delivering a prospectus, the holder will not be deemed to
admit that it is an "underwriter" within the meaning of the Securities Act.

ACCEPTANCE OF OLD NOTES FOR EXCHANGE, DELIVERY OF NEW NOTES

    Upon satisfaction or waiver of all of the conditions to the exchange offer,
we will accept, promptly after the expiration date, all old 7.25% Notes and all
old 7.75% Notes properly tendered and will issue the new 7.25% Notes and the new
7.75% Notes, as applicable, promptly after acceptance of the old 7.25% Notes and
the old 7.75% Notes, respectively. See "--Conditions Of The Exchange Offer"
below. We will be deemed to have accepted properly tendered old 7.25% Notes and
properly tendered old 7.75% Notes for exchange when we have given oral or
written notice to the exchange agent.

    For each old 7.25% Note and each old 7.75% Note validly tendered to us, the
holder of the applicable old Note will receive an applicable new Note having a
principal amount equal to the principal amount of the tendered old Note. The new
7.25% Notes will bear interest at the same rate and on the same terms as the old
7.25% Notes and the new 7.75% Notes will bear interest at the same rate and on
the same terms as the old 7.75% Notes. Consequently, interest on the new 7.25%
Notes will accrue at a rate of 7.25% per annum and interest on the new 7.75%
Notes will accrue at a rate of 7.75% per annum and, with regard to all Notes,
will be payable semiannually in arrears on February 15 and August 15 of each
year, commencing August 15, 2001. Interest on each new Note will accrue from the
last interest payment date on which interest was paid on the respective
surrendered old Note or, if no interest has been paid on such old Note, from the
date of the original issuance thereof.

    The issuance of new Notes for old Notes that are accepted for exchange in
the exchange offer will be made only after timely receipt by the exchange agent
of certificates for the old Notes or a timely book-entry confirmation of the old
Notes into the exchange agent's account at the book-entry transfer facility, a
completed and signed letter of transmittal and all other required documents. If
any tendered old Notes are not accepted for any reason set forth in the terms
and conditions of the

                                       13

exchange offer, or if old Notes are submitted for a greater amount than the
holder desires to exchange, the unaccepted or non-exchanged old Notes will be
returned without expense to the tendering holder as promptly as practicable
after the exchange offer expires or terminates. In the case of old Notes
tendered by book-entry procedures described below, the non-exchanged old Notes
will be credited to an account maintained with the book-entry transfer facility.

CONDITIONS OF THE EXCHANGE OFFER

    We will not be required to accept for exchange any old 7.25% Notes or any
old 7.75% Notes and may terminate or amend the exchange offer before the
expiration date, if we determine that we are not permitted to effect the
exchange offer because of:

    - any changes in law, or applicable interpretations by the SEC; or

    - any action or proceeding is instituted or threatened in any court or
      governmental agency with respect to the exchange offer.

    If we determine that any of the conditions are not satisfied, we may refuse
to accept any old 7.25% Notes or any old 7.75% Notes and return all tendered old
7.25% Notes or all tendered old 7.75% Notes, as the case may be, to the
tendering holders or extend the exchange offer and retain all old 7.25% Notes
and all old 7.75% Notes tendered before the expiration date, subject to the
rights of holders to withdraw such old 7.25% Notes and old 7.75% Notes or waive
such unsatisfied conditions with respect to the exchange offer and accept all
properly tendered old 7.25% Notes and old 7.75% Notes, as the case may be, that
have not been withdrawn. If such waiver or amendment constitutes a material
change to the exchange offer, we will promptly disclose such waiver or amendment
by means of a prospectus supplement that will be distributed to the registered
holders of the old Notes and we will extend the exchange offer to the extent
required by Rule 14e-1 under the Exchange Act.

    Holders may have certain rights and remedies against us under the
Registration Rights Agreement if we fail to close the exchange offer, whether or
not the conditions stated above occur. These conditions are not intended to
modify those rights or remedies. See "REGISTRATION RIGHTS."

BOOK ENTRY TRANSFER

    The exchange agent will make a request to establish an account for the old
7.25% Notes and for the old 7.75% Notes at the book-entry transfer facility for
the exchange offer within two business days after the date of this prospectus,
and any financial institution that is a participant in the book-entry transfer
facility's systems may make book-entry delivery of old 7.25% Notes or old 7.75%
Notes by causing the book-entry transfer facility to transfer the applicable old
Notes into the exchange agent's account at the book-entry transfer facility in
accordance with the book-entry transfer facility's procedures for transfer.
However, although delivery of old Notes may be effected through book-entry
transfer at the book-entry transfer facility, the letter of transmittal or
facsimile, or an agent's message, with any required signature guarantees and any
other required documents, must be received by the exchange agent at one of the
addresses set forth below under "--Exchange Agent" on or before the expiration
date or the guaranteed delivery procedures described below must be complied
with.

    The term "agent's message" means a message, transmitted by DTC to the
exchange agent and forming a part of a book-entry confirmation, which states
that DTC has received an express acknowledgment from the tendering participant
stating that the participant has received and agrees to be bound by the terms of

against the participant.

GUARANTEED DELIVERY PROCEDURES

    If a registered holder wishes to tender its old Notes and the old Notes are
not immediately available, or time will not permit the holder's old Notes or
other required documents to reach the exchange agent before the expiration date,
or the procedure for book-entry transfer cannot be completed on time, the old
Notes may nevertheless be exchanged if:

    - the tender is made through an eligible guarantor institution;

    - before the expiration date, the exchange agent has received from the
      eligible guarantor institution an agent's message with respect to
      guaranteed delivery or a completed and signed letter of transmittal, or a
      facsimile, and a notice of guaranteed delivery, substantially in the form
      provided by us. Delivery may be made by facsimile transmission, mail or
      hand delivery. The letter of transmittal and notice of guaranteed delivery
      must set forth the name and address of the holder of the old Notes and the
      amount of the old 7.25% Notes or old 7.75% Notes being tendered, state
      that the tender is being made and guarantee that within five trading days
      on the New York Stock Exchange ("NYSE") after the date of signing of the
      notice of guaranteed delivery, the applicable certificates for all
      physically tendered old Notes, in proper form for transfer, or a
      book-entry confirmation, and any other documents required by the letter of
      transmittal, will be deposited by the eligible guarantor institution with
      the exchange agent; and

    - the applicable certificates for all physically tendered old Notes, in
      proper form for transfer, or a book-entry confirmation and all other
      documents required by the letter of transmittal, are received by the
      exchange agent within five NYSE trading days after the date of signing the
      notice of guaranteed delivery.

WITHDRAWAL RIGHTS

    Tenders of old 7.25% Notes or old 7.75% Notes may be withdrawn at any time
before the close of business on the expiration date.

    For a withdrawal to be effective, a written notice of withdrawal must be
received by the exchange agent at one of the addresses set forth below under
"--Exchange Agent." Notice may be sent by facsimile transmission, mail or hand
delivery. Any notice of withdrawal must:

    - specify the name of the person who tendered the old Notes to be withdrawn;

    - identify the applicable old Notes to be withdrawn, including the amount of
      the old 7.25% Notes or the old 7.75% Notes;

    - where certificates for old Notes have been transmitted, specify the name
      in which the old Notes are registered, if different from that of the
      withdrawing holder; and

    - state that such holder of the old Notes is withdrawing his election to
      have such old Notes tendered.

    If certificates for old Notes have been delivered or otherwise identified to
the exchange agent, then, before the release of the certificates the withdrawing
holder must also submit the serial numbers of the particular certificates to be
withdrawn and a signed notice of withdrawal with signatures guaranteed by an
eligible guarantor institution unless the holder is an eligible guarantor
institution. If old Notes have been tendered under the procedure for book-entry
transfer described above, any notice of withdrawal must specify the name and
number of the account at the book-entry transfer facility to be credited with
the withdrawn old Notes and otherwise comply with the procedures of the
facility. We will determine all questions as to the validity, form, eligibility
and time of receipt of the notices, and our determination will be final and
binding on all parties. Any old

                                       15

Notes so withdrawn will be deemed not to have been validly tendered for exchange
for purposes of the exchange offer. Any old Notes that have been tendered for
exchange, but that are not exchanged for any reason will be returned to the
holder without cost to the holder as soon as practicable after withdrawal,
rejection of tender or termination of the exchange offer. In the case of old
Notes tendered by book-entry transfer into the exchange agent's account at the
book-entry transfer facility under the book-entry transfer procedures described
above, the old Notes will be credited to an account with the book-entry transfer
facility specified by the holder. Properly withdrawn old Notes may be re-
tendered by following one of the procedures described under "--Procedures For
Tendering Old Notes" above at any time on or before the expiration date.

    Delivery of a letter of transmittal to an address other than as set forth

above does not constitute a valid delivery of the letter of transmittal.

FEES AND EXPENSES

    We will not make any payment to brokers, dealers or others soliciting
acceptances of the exchange offer and holders who tender old Notes will not be
required to pay brokerage commissions or fees.

    We will pay the expenses that will be incurred in connection with the
exchange offer. We estimate the expenses will be approximately $100,000.

ACCOUNTING TREATMENT

    For accounting purposes, we will recognize no gain or loss as a result of
the exchange offer. The expenses of the exchange offer will be amortized over
the term of the new Notes.

                                       16

TRANSFER TAXES

    Holders who instruct us to register new Notes in the name of a person other
than the registered tendering holder will be responsible for paying any
applicable transfer tax, as will holders who request that old Notes not tendered
or not accepted in the exchange offer be returned to a person other than the
registered tendering holder. In all other cases, no transfer taxes will be due.

REGULATORY MATTERS

    We are not aware of any governmental or regulatory approvals that are
required in order to complete the exchange offer.

RESALES OF THE NEW NOTES

    With respect to resales of new Notes, based on certain interpretive letters
issued by the Staff of the SEC to third parties, we believe that a holder of
Notes (other than (i) a broker-dealer who purchased old Notes directly from us
to resell pursuant to Rule 144A or any other available exemption under the
Securities Act or (ii) a person who is an affiliate of ours or Qwest's within
the meaning of Rule 405 under the Securities Act) who exchanges old Notes for
new Notes in the ordinary course of business and who is not participating, does
not intend to participate, and has no arrangement or understanding with any
person to participate, in the distribution of the new Notes, will be allowed to
resell the new Notes to the public without further registration under the
Securities Act and without delivering to the purchasers of the new Notes a
prospectus that satisfies the requirements of the Securities Act. However, a
broker-dealer who holds old Notes that were acquired for its own account as a
result of market making or other trading activities may be deemed to be an
"underwriter" within the meaning of the Securities Act and must, therefore,
deliver a prospectus meeting the requirements of the Securities Act. For a
period of 180 days from the expiration of the exchange offer, we will make this
prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale. If any other holder is deemed to be an
"underwriter" within the meaning of the Securities Act or acquires new Notes in
the exchange offer for the purpose of distributing or participating in a
distribution of the new Notes, such holder must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction, unless an exemption from registration is otherwise
available.

CONSEQUENCES OF FAILURE TO EXCHANGE

    Participation in the exchange offer is voluntary. Old Notes that are not
exchanged for new Notes will remain outstanding, continue to accrue interest and
will be restricted securities. Accordingly, those old Notes may only be
transferred:

    - to a person who the seller reasonably believes is a qualified
      institutional buyer under Rule 144A under the Securities Act;

    - in an offshore transaction under Rule 903 or Rule 904 of Regulation S
      under the Securities Act; or

    - under Rule 144 under the Securities Act (if available);

and in accordance with all applicable securities laws of the states of the
United States. Following the consummation of the exchange offer, neither we nor
Qwest will have any further obligation to such holders to provide for
registration under the Securities Act, except that under certain circumstances,
we are required to file a shelf registration statement under the Securities Act.
See "REGISTRATION RIGHTS."

                                       17

PAYMENT OF ADDITIONAL INTEREST UPON REGISTRATION DEFAULTS

    If we fail to meet our obligations to complete the exchange offer or file a
shelf registration statement, additional interest will accrue on the Notes. For
additional information regarding payments of additional interest, please see
"REGISTRATION RIGHTS."

USE OF PROCEEDS

    We will not receive any proceeds from the issuance of the new Notes or the
closing of the exchange offer.

                            DESCRIPTION OF NEW NOTES

GENERAL

    Each of the new 7.25% Notes and the new 7.75% Notes will constitute separate
series of debt securities ("Debt Securities") under an indenture dated as of
June 29, 1998, as supplemented and amended from time to time (the "Indenture"),
among us, Qwest and Bank One Trust Company, National Association, as trustee
(the "Trustee"). The new 7.25% Notes and the old 7.25% Notes, together, and the
new 7.75% Notes and the old 7.75% Notes, together, are each considered to be a
single series for all purposes under the Indenture. The following summaries of
certain provisions of the Indenture do not purport to be complete and are
subject to and are qualified in their entirety by reference to all of the
provisions of the Indenture, which provisions of the Indenture are incorporated
herein by reference. Capitalized and other terms not otherwise defined herein
will have the meanings given to them in the Indenture. You may obtain a copy of
the Indenture from us upon request. See "WHERE YOU CAN FIND MORE INFORMATION."

    The Indenture does not limit the aggregate principal amount of Debt
Securities that may be issued thereunder and provides that Debt Securities may
be issued thereunder from time to time in one or more series. All Debt
Securities, including the new Notes are, and will be unconditionally guaranteed
as to payment of principal, premium, if any, and interest by Qwest (the
"Guarantees"). As of the date of this prospectus, the principal amount of Debt
Securities outstanding under the Indenture is approximately $7.95 billion,
excluding the Notes.

    Since the new Notes will constitute separate series of Debt Securities under
the Indenture, holders of old 7.25% Notes who do not exchange such old 7.25%
Notes for new 7.25% Notes will vote together as a separate series of Debt
Securities with holders of such new 7.25% Notes of that series for all relevant
purposes under the Indenture. Holders of old 7.75% Notes who do not exchange
such old 7.75% Notes for new 7.75% Notes will vote together as a separate series
of Debt Securities with holders of such new 7.75% Notes of that series for all
relevant purposes under the Indenture. In that regard, the Indenture requires
that certain actions by the holders under such old 7.25% Notes and old 7.75%
Notes (including acceleration following an Event of Default) must be taken, and
certain rights must be exercised, by specified minimum percentages of the
aggregate principal amount of the outstanding Notes of the applicable series. In
determining whether holders of the requisite percentage in principal amount of
the Notes of the applicable series have given any notice, consent or waiver or
taken any other action permitted under the Indenture, any old 7.25% Notes that
remain outstanding after the exchange offer will be aggregated with the new
7.25% Notes and the holders of the old 7.25% Notes and the new 7.25% Notes will
vote together as a single series for all purposes. The same will be true for the
holders of old 7.75% Notes and new 7.75% Notes. Accordingly, all references in
this section will be deemed to mean, at any time after the exchange offer is
consummated, the requisite percentage in aggregate principal amount of the old
7.25% Notes and the new 7.25% Notes and the old 7.75% Notes and the new 7.75%
Notes, as the case may be.

    The Notes will be issued only in registered form, without coupons, in
denominations of $1,000 and integral multiples thereof. The Notes are unsecured
obligations of ours and rank equally with all of our other unsecured and
unsubordinated indebtedness. The Guarantees are unsecured obligations of Qwest
and rank equally with all other unsecured and unsubordinated indebtedness of
Qwest. However, because Qwest is a holding company that conducts substantially
all of its operations through subsidiaries, the right of Qwest, and hence the
right of creditors of Qwest (including holders of the Notes through the
Guarantees), to participate in any distribution of assets of any subsidiary upon
its liquidation or reorganization or otherwise is necessarily subject to the
prior claims of creditors of such subsidiary, except to the extent that claims
of Qwest itself as a creditor of the subsidiary may be recognized.

                                       20

    Interest on the Notes will be payable semiannually in arrears on
February 15 and August 15 of each year, commencing August 15, 2001 (each an
"Interest Payment Date"), to the persons in whose names the Notes are registered
at the close of business on February 1 or August 1, as the case may be,
immediately preceding such Interest Payment Date. Interest will be calculated on
the basis of a 360-day year of twelve 30-day months. If any Interest Payment
Date, maturity date or redemption date is a Legal Holiday in New York, New York,
the required payment will be made on the next succeeding day that is not a Legal
Holiday as if it were made on the date such payment was due and no interest will
accrue on the amount so payable for the period from and after such Interest
Payment Date, maturity date or redemption date, as the case may be, to such next
succeeding day. "Legal Holiday" means a Saturday, a Sunday or a day on which
banking institutions in the City of New York are not required to be open.

    The 7.25% Notes initially will be limited to $2,250,000,000 aggregate
principal amount. We and Qwest may "reopen" any series of Debt Securities and
issue additional securities of that series without the consent of the holders of
that series. The 7.25% Notes are unsecured obligations of ours and rank equally
with all of our other unsecured and unsubordinated indebtedness. The 7.25% Notes
are unconditionally guaranteed as to payment of principal, premium, if any, and
interest by Qwest and the Guarantees rank equally with all of Qwest's other
unsecured and unsubordinated obligations. The 7.25% Notes will bear interest at
the rate of 7.25% per annum from and including February 14, 2001 or from the
most recent interest payment date to which interest has been paid or duly
provided for. The 7.25% Notes will mature and the principal amount will be
payable on February 15, 2011. The 7.25% Notes will not have the benefit of any
sinking fund.

    The 7.75% Notes initially will be limited to $1,000,000,000 aggregate
principal amount. We and Qwest may "reopen" any series of Debt Securities and
issue additional securities of that series without the consent of the holders of
that series. The 7.75% Notes are unsecured obligations of ours and rank equally
with all of our other unsecured and unsubordinated indebtedness. The 7.75% Notes
are unconditionally guaranteed as to payment of principal, premium, if any, and
interest by Qwest and the Guarantees rank equally with all of Qwest's other
unsecured and unsubordinated obligations. The 7.75% Notes will bear interest at
the rate of 7.75% per annum from and including February 14, 2001, or from the
most recent interest payment date to which interest has been paid or duly
provided for. The 7.75% Notes will mature and the principal amount will be
payable on February 15, 2031. The 7.75% Notes will not have the benefit of any
sinking fund.

    Holders of certificated Notes must surrender the Notes to the paying agent
to collect principal and interest payments at maturity. Principal, premium, if
any, and interest on certificated Notes will be payable at the office of the
paying agent maintained for such purpose or, at our option, payment of principal
and interest may be made by check mailed to a holder's registered address.

    Payment of principal of and interest and premium, if any, on any Notes
represented by one or more permanent global notes in definitive, fully
registered form without interest coupons (the "Global Notes") will be made to
Cede & Co., the nominee for DTC, as the registered owner of the Global Notes by
wire transfer of immediately available funds as described in "--Book-Entry Only;
Delivery And Form." The Trustee, through its corporate trust office in the
Borough of Manhattan in The City of New York (in such capacity, the "Paying
Agent") will act as our paying agent with respect to the Notes. Payments of
principal, premium, if any, and interest on the Notes will be made by us through
the Paying Agent to DTC.

    The principal of, premium, if any, and interest on the Notes will be payable
in U.S. dollars or in such other coin or currency of the United States of
America as at the time of payment is legal tender for the payment of public and
private debts. No service charge will be made for any registration of, transfer
or exchange of Notes, but we may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith. The Notes
may be

                                       21

presented for registration of transfer or exchange at the office of the Paying
Agent in the Borough of Manhattan in the City of New York, or at any other
office or agency maintained by us or the Paying Agent for such purpose.

OPTIONAL REDEMPTION

    The Notes will be redeemable at our option, in whole at any time or in part
from time to time, on at least 15 days but not more than 60 days prior written
notice mailed to the registered holders thereof, at a redemption price equal to
the greater of (i) 100% of the principal amount of the Notes to be redeemed or
(ii) the sum, as determined by the Quotation Agent (as defined below), of the
present values of the principal amount of the Notes to be redeemed and the
remaining scheduled payments of interest thereon from the redemption date to the
maturity date of the Notes to be redeemed, exclusive of interest accrued to the
redemption date (the "Remaining Life"), discounted from their respective
scheduled payment dates to the redemption date on a semiannual basis (assuming a
360-day year consisting of 30-day months) at the Treasury Rate (as defined
below) plus 20 basis points, in the case of the 7.25% Notes, and 25 basis
points, in the case of the 7.75% Notes, plus, in both cases, accrued and unpaid
interest on the principal amount being redeemed to the date of redemption.

    If money sufficient to pay the redemption price of and accrued interest on
all of the Notes (or portions thereof) to be redeemed on the redemption date is
deposited with the Trustee or Paying Agent on or before the redemption date and
certain other conditions are satisfied, then on and after such redemption date,
interest will cease to accrue on such Notes (or such portion thereof) called for
redemption.

    "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the Remaining
Life that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity with the Remaining Life.

    "Comparable Treasury Price" means, with respect to any redemption date, the
average of two Reference Treasury Dealer Quotations for such redemption date.

    "Quotation Agent" means the Reference Treasury Dealer appointed by us.

    "Reference Treasury Dealer" means each of Banc of America Securities LLC and
Chase Securities Inc., and their successors; provided, however, that if any of
the foregoing will cease to be a primary U.S. Government securities dealer in
New York City (a "Primary Treasury Dealer"), we will substitute therefor another
Primary Treasury Dealer.

    "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third business day preceding such redemption date.

    "Treasury Rate" means, with respect to any redemption date, the rate per
annum equal to the semiannual yield to maturity of the Comparable Treasury
Issue, calculated on the third business day preceding such redemption date using
a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such redemption
date.

    We or Qwest may at any time, and from time to time, purchase the Notes at
any price or prices in the open market or otherwise.

                                       22

BOOK ENTRY ONLY; DELIVERY AND FORM

    The new Notes will initially be issued in the form of global securities held
in book-entry form. The new Notes will be deposited with the Trustee as
custodian for DTC and registered in the name of Cede & Co., as nominee of DTC
("Nominee"). Except as set forth below, a global security may not be transferred
except as a whole by DTC Nominee, or by Nominee to DTC.

    When a global security is issued, DTC or Nominee will credit, on its
internal system, the accounts of persons holding through it with the principal
amounts of the individual beneficial interest represented by the global security
purchased by those persons in the offering of the new Notes. The accounts were
initially designated by the initial purchasers of the old Notes with respect to
old Notes sold by the initial purchasers.

    Payment of principal and of interest and premium, if any, on the global
securities will be made to Nominee as the registered owner of the global
securities by wire transfer of immediately available funds. None of us, Qwest or
the Trustee will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in the global securities or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interest.

    We have been informed by DTC that upon receipt of any payment of principal
of or interest or premium, if any, on the global securities, DTC will credit the
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the global securities as shown on the records
of DTC. Payment by the participants to owners of beneficial interests in the
global securities held through such participants will be the responsibility of
such participants, as is the case with securities held by broker-dealers, either
directly or through nominees, for the accounts of customers and registered in
"street name."

    Because DTC can act only on behalf of participants, who in turn act on
behalf of indirect participants and certain banks, the ability of a person
having a beneficial interest in the global securities to pledge such interest to
persons or entities that do not participate in the DTC system, or otherwise take
actions in respect of such interest, may be affected by the lack of physical
certificate.

    Only participants that have accounts with DTC or persons that hold interests
through participants can own beneficial interests in a global security.
Ownership of beneficial interests by participants in a global security will be
shown on records maintained by DTC or Nominee for the global security, and that
ownership interest will be transferred only through those records. Ownership of
beneficial interests in the global security by persons that hold through
participants will be shown on records maintained by the participant, and the
transfer of that ownership interest within the participant will occur only
through the participant's records.

    The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of the securities in definitive form. Those limits and
laws may make it more difficult to transfer beneficial interests in a global
security. We will make payments on the new Notes represented by any global
security to DTC or Nominee as the sole registered owner and the sole holder of
the new Notes represented by the global security. Neither we, Qwest nor the
Trustee, any agent of ours or the initial purchasers will have any
responsibility for any aspect of DTC's reports relating to beneficial ownership
interests in a global security representing any new Notes or for reviewing any
of DTC's records relating to the beneficial ownership interests. DTC has advised
us that upon receipt of any payment on any global security, DTC will immediately
credit, on its book-entry registration and transfer system, the accounts of
participants with payments in amounts proportionate to their beneficial
interests in the principal or face amount of the global security. We expect that
payments by participants to owners of beneficial interests in a global security
held

                                       23

through those participants will be governed by standing instructions and
customary practices as is now the case with securities held for customer
accounts registered in "street name" and will be the sole responsibility of the
participants subject to any statutory or regulatory requirements as may be in
effect from time to time.

    So long as DTC or Nominee is the registered owner of the global security,
DTC or Nominee will be considered the sole owner or holder of the new Notes
represented by the global security for the purposes of receiving payment on the
new Notes, receiving notices and for all other purposes under the Indenture and
the new Notes. Except as provided above, owners of beneficial interests in a
global security will not be entitled to receive physical delivery of
certificated new Notes and will not be considered the holders of the global
security for any purposes under the Indenture. Accordingly, each person owning a
beneficial interest in a global security must rely on the procedures of DTC and,
if the person is not a participant, on the procedures of the participant through
which the person owns its interest, to exercise any rights of a holder under the
global security or the Indenture. We understand that under existing industry
practices, if we request any action of holders or an owner of a beneficial
interest in a global security wants to take any action that a holder is entitled
to take under the Indenture, DTC would authorize the participants holding the
beneficial interest to take that action, and the participants would authorize
beneficial owners owning through the participants to take the action on the
instructions of beneficial owners owning through them.

    DTC has advised us that it will take any action permitted to be taken by a
holder of new Notes only at the direction of a participant to whose account with
DTC interests in the global security are credited and only as to the portion of
the aggregate principal amount of the new Notes as to which the participant has
given that direction. DTC has advised us that DTC is a limited-purpose trust
company organized under the Banking Law of the State of New York, a "banking
organization" within the meaning of New York Banking Law, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code and a "clearing agency" registered under the
Exchange Act. DTC was created to hold the securities of its participants and to
facilitate the clearance and settlement of securities transactions among its
participants in the securities through electronic book-entry changes in accounts
of the participants. This eliminates the need for physical movement of
securities certificates. DTC's participants include securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations, some of whom own DTC. Access to DTC's book-entry system is also
available to others, such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a participant.

CERTIFICATED NEW NOTES

    New 7.25% Notes and new 7.75% Notes represented by the applicable global
securities are exchangeable for certificated new 7.25% Notes or certificated new
7.75% Notes, respectively, only if:

    - DTC notifies us that it is unwilling or unable to continue as a depository
      for the global security or if at any time DTC ceases to be a registered
      clearing agency, and a successor depository is not appointed by us within
      90 days;

    - we notify the Trustee that the global security will be so transferable,
      registrable and exchangeable; or

    - an event of default with respect to the new 7.25% Notes or the new 7.75%
      Notes, as the case may be, has occurred and is continuing.

                                       24

    Any global security that is exchangeable for certificated new Notes under
the preceding sentence will be transferred to, and registered and exchanged for,
certificated new Notes in authorized denominations and registered in names that
DTC or its nominee holding the global security may direct. Subject to the
foregoing, a global security is not exchangeable, except for a global security
of the same denomination to be registered in the name of DTC or its nominee. If
a global security becomes exchangeable for certificated new 7.25% Notes or
certificated new 7.75% Notes, as the case may be:

    - certificated new Notes will be issued only in fully registered form in
      denominations of $1,000 or integral multiples;

    - payments will be made and transfers will be registered at the office or
      agency of us maintained for that purposes; and

    - no service charge will be made for any issuance of the certificated new
      Notes, although we may require payment to cover any tax or governmental
      charge imposed.

    According to DTC, the foregoing information with respect to DTC has been
provided to the Industry for informational purposes only and is not intended to
serve as a representation, warranty, or contract modification of any kind.

SAME-DAY SETTLEMENT AND PAYMENT

    Settlement for the new Notes represented by the Global Notes will be made in
immediately available funds. We will make all payments of principal of and
interest and premium, if any, on the Notes in immediately available funds.

    The new Notes will trade in DTC's Same-Day Funds Settlement System until
maturity, and secondary market trading activity in the new Notes will therefore
be required by DTC to settle in immediately available funds.

CERTAIN COVENANTS

    Other than as described below under "--Limitation On Liens," the Indenture
does not contain any provisions that would limit our or Qwest's ability to incur
indebtedness or that would afford holders of Notes protection in the event of a
sudden and significant decline in our or Qwest's credit quality or a takeover,
recapitalization or highly leveraged or similar transaction involving us or
Qwest. Accordingly, we or Qwest could in the future enter into transactions that
could increase the amount of indebtedness outstanding at that time or otherwise
adversely affect our or Qwest's capital structure or credit rating. See "CREDIT
RATINGS."

LIMITATION ON LIENS

    The Indenture contains a covenant that if we mortgage, pledge or otherwise
subject to any lien all or some of our property or assets, we will secure the
Notes, any other outstanding Debt Securities and any of our other obligations
which may then be outstanding and entitled to the benefit of a covenant similar
in effect to such covenant, equally and proportionally with the indebtedness or
obligations secured by such mortgage, pledge or lien, for as long as any such
indebtedness or obligation is so secured. This covenant does not apply to:

    - the creation, extension, renewal or refunding of (a) mortgages or liens
      created or existing at the time property is acquired, (b) mortgages or
      liens created within 180 days after property is acquired, or
      (c) mortgages or liens securing the cost of construction or improvement of
      property; or

                                       25

    - the making of any deposit or pledge to secure public or statutory
      obligations or with any governmental agency at any time required by law in
      order to qualify us to conduct all or some part of our business or in
      order to entitle us to maintain self-insurance or to obtain the benefits
      of any law relating to workmen's compensation, unemployment insurance, old
      age pensions or other social security, or with any court, board,
      commission or governmental agency as security incident to the proper
      conduct of any proceeding before it.

    The Indenture does not prevent any other entity from mortgaging, pledging or
subjecting to any lien any of its property or assets, whether or not acquired
from us or Qwest (Section 4.03).

CONSOLIDATION, MERGER AND SALE OF ASSETS

    We may, without the consent of the holders of the Notes or any other
outstanding Debt Securities, consolidate with, merge into or be merged into, or
transfer or lease our property and assets substantially as an entirety to
another entity. However, we may only do this if:

    - the successor entity is a corporation and assumes by supplemental
      indenture all of our obligations under the Notes, any other outstanding
      Debt Securities and the Indenture; and

    - after giving effect to the transaction, no Default or Event of Default has
      occurred and is continuing.

    After that time, all of our obligations under the Notes, any other
outstanding Debt Securities and the Indenture terminate (Section 5.01).

    Qwest may, without the consent of the holders of any of the Notes or any
other outstanding Debt Securities, consolidate with, merge into or be merged
into, or transfer or lease its property and assets substantially as an entirety
to another entity. However, Qwest may only do this if:

    - the successor entity is a corporation and assumes by supplemental
      indenture all of its obligations under the Guarantees and the Indenture;
      and

    - after giving effect to the transaction, no Default or Event of Default has
      occurred and is continuing.

    After that time, all of Qwest's obligations under the Guarantees and the
Indenture terminate (Section 5.02).

EVENTS OF DEFAULT

    Any one of the following is an Event of Default with respect to any series
of Debt Securities, including the 7.25% Notes and the 7.75% Notes
(Section 6.01):

    - if we or Qwest default in the payment of interest on the Debt Securities
      of such series, and such default continues for 90 days;

    - if we or Qwest default in the payment of the principal of any Debt
      Security of such series when the same becomes due and payable at maturity,
      upon redemption, or otherwise;

    - if we or Qwest fail to comply with any of our or their other agreements in
      the Debt Securities of such series, in the Indenture or in any
      supplemental indenture under which the Debt Securities of such series were
      issued, which failure continues for 90 days after we or Qwest receive
      notice from the Trustee or the holders of at least 25% in principal amount
      of all of the outstanding Debt Securities of that series; and

    - if certain events of bankruptcy or insolvency occur with respect to us or
      Qwest.

                                       26

    If an Event of Default with respect to the Debt Securities of any series
occurs and is continuing, the Trustee or the holders of at least 25% in
principal amount of all of the outstanding Debt Securities of that series may
declare the principal (or, if the Debt Securities of that series are original
issue discount securities, such portion of the principal amount as may be
specified in the terms of that series) of all the Debt Securities of that series
to be due and payable. When such declaration is made, such principal (or, in the
case of original issue discount securities, such specified amount) will be
immediately due and payable (Section 6.02). The holders of a majority in
principal amount of Debt Securities of that series may rescind such declaration
and its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default have been cured or waived (other
than nonpayment of principal or interest that has become due solely as a result
of acceleration).

    Holders of Debt Securities may not enforce the Indenture, the Debt
Securities or the Guarantees, except as provided in the Indenture. The Trustee
may require indemnity satisfactory to it before it enforces the Indenture or the
Debt Securities (Section 7.01(e)). Subject to certain limitations, the holders
of more than 50% in principal amount of the Debt Securities of each series
affected (with each series voting as a class) may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power of the Trustee (Section 6.05). The Trustee may
withhold from holders of Debt Securities notice of any continuing default
(except a default in the payment of principal or interest) if it determines in
good faith that withholding notice is in their interests (Section 7.05).

AMENDMENT AND WAIVER

    With the written consent of the holders of more than 50% of the principal
amount of the outstanding Debt Securities of each series that will be affected
(with each series voting as a class), we, Qwest and the Trustee may amend or
supplement the Indenture or modify the rights of the holders of Debt Securities
of that series. Such majority of holders may also waive compliance by us or
Qwest with any provision of the Indenture, any supplemental indenture or the
Debt Securities of any such series except a default in the payment of principal
or interest. However, without the consent of the holder of each Debt Security
affected, an amendment or waiver may not (Section 9.02):

    - reduce the amount of Debt Securities whose holders must consent to an
      amendment or waiver;

    - change the rate or the time for payment of interest;

    - change the principal or the fixed maturity;

    - waive a default in the payment of principal or interest, if any;

    - make any Debt Security payable in a different currency; or

    - make any change in the provisions of the Indenture concerning (a) waiver
      of existing defaults (Section 6.04), (b) rights of holders of Debt
      Securities to receive payment (Section 6.07), or (c) amendments and
      waivers with consent of holders of Debt Securities (Section 9.02(a), third
      sentence).

    We, Qwest and the Trustee may amend or supplement the Indenture without the
consent of any holder of any of the Debt Securities (Section 9.01):

    - to cure any ambiguity, defect or inconsistency in the Indenture, the Debt
      Securities or the Guarantees;

                                       27

    - to provide for the assumption of all of our obligations under the Debt
      Securities and the Indenture or of Qwest's obligations under the
      Guarantees and the Indenture by any corporation in connection with a
      merger, consolidation or transfer or lease of our or Qwest's property and
      assets substantially as an entirety;

    - to provide for uncertificated Debt Securities in addition to or instead of
      certificated Debt Securities;

    - to make any change that does not adversely affect the rights of any holder
      of Debt Securities;

    - to provide for the issuance of and establish the form and terms and
      conditions of a series of Debt Securities or the Guarantees, or to
      establish the form of any certifications required to be furnished pursuant
      to the terms of the Indenture or any series of Debt Securities;

    - to add to the rights of holders of any of the Debt Securities; or

    - to secure any Debt Securities as provided under the heading "--Limitation
      On Liens."

DEFEASANCE

    We and Qwest may defease all of our or their obligations under the 7.25%
Notes and the 7.75% Notes and the Indenture with respect to the 7.25% Notes or
the 7.75% Notes or any installment of interest on the Notes if we or Qwest
irrevocably deposit in trust with the Trustee money or U.S. Government
Obligations sufficient to pay, when due, principal and interest on the 7.25%
Notes or the 7.75% Notes to maturity or redemption or such installment of
interest, as the case may be, and if all other conditions set forth in the 7.25%
Notes or the 7.75% Notes are met (Section 8.01).

GUARANTEES

    As described in more detail above under "--General", Qwest has
unconditionally guaranteed the payment of principal and interest on the Notes
when and as such payments become due and payable. The Guarantees rank equally
with all other unsecured and unsubordinated obligations of Qwest. The Notes and
the guarantees are unsecured obligations of ours and Qwest, respectively, and
rank pari passu among them.

GOVERNING LAW

    The Indenture and the Notes will be governed by, and construed in accordance
with, the laws of the State of New York.

CONCERNING THE TRUSTEE AND THE PAYING AGENT

    Qwest and certain of its affiliates, including us, maintain banking and
other business relationships in the ordinary course of business with Bank One
Trust Company, National Association. In addition, Bank One Trust Company,
National Association and certain of its affiliates serve as trustee,
authenticating agent, or paying agent with respect to certain Debt Securities of
Qwest and its affiliates.

                                       28

                              REGISTRATION RIGHTS

    Based on an interpretation by the Staff of the SEC set forth in no-action
letters, and subject to the immediately following sentence, we and Qwest believe
that the new Notes to be issued pursuant to the exchange offer may be offered
for resale, resold and otherwise transferred by the holders thereof (other than
holders who are broker-dealers) without further compliance with the registration
and prospectus delivery provisions of the Securities Act. However, any purchaser
of old Notes who is an affiliate of us or Qwest or who intends to participate in
the exchange offer for the purpose of distributing the new 7.25% Notes or the
new 7.75% Notes, as the case may be, or any broker-dealer who purchased the old
Notes from us for resale pursuant to Rule 144A or any other available exemption
under the Securities Act:

    - will not be able to rely on the interpretations of the Staff set forth in
      the no-action letters;

    - will not be entitled to tender such old Notes in the exchange offer; and

    - must comply with the registration and prospectus delivery requirements of
      the Securities Act in connection with any sale or transfer of the old
      Notes unless such sale or transfer is made pursuant to an exemption from
      such requirements.

    Neither we nor Qwest intend to seek our own no-action letter, and there can
be no assurance that the Staff would make a similar determination with respect
to the new Notes as it has in such no-action letters to third parties. Each
holder of the old Notes (other than certain specified holders) who wishes to
exchange the old Notes for new Notes in the exchange offer will be required to
represent that:

    - it is not an affiliate of us or Qwest;

    - it is not a broker-dealer tendering Registrable Securities (as defined in
      the Registration Rights Agreement) acquired directly from us;

    - the old Notes to be exchanged for new Notes in the exchange offer were
      acquired in the ordinary course of its business; and

    - at the time of the exchange offer, it has no arrangement or understanding
      with any person to participate in the distribution (within the meaning of
      the Securities Act) of the new Notes.

    In addition, in connection with any resale of new Notes, any broker-dealer
who acquired the new Notes for its own account as a result of market-making or
other trading activities (a "Participating Broker-Dealer") and who receives new
notes in exchange for such old notes pursuant to the exchange offer, may be
deemed to be an "underwriter" within the meaning of the Securities Act and must
deliver a prospectus meeting the requirements of the Securities Act. The SEC has
taken the position that Participating Broker-Dealers may fulfill their
prospectus delivery requirements with respect to the new Notes other than a
resale of an unsold allotment from the original sale thereof, with the
prospectus contained in the registration statement filed in connection with the
exchange offer (the "Exchange Offer Registration Statement"). Under the
Registration Rights Agreement, we and Qwest are required to allow Participating
Broker-Dealers and other persons, if any, subject to similar prospectus delivery
requirements to use the prospectus contained in the Exchange Offer Registration
Statement in connection with the resale of such new Notes for a period of 240
calendar days from the issuance of the new Notes.

    If:

    - because of any change in law or in currently prevailing interpretations of
      the Staff, we or Qwest are not permitted to effect the exchange offer;

    - the exchange offer is not consummated within 240 calendar days of the
      closing date; or

                                       29

    - in the case of any holder that participates in the exchange offer, such
      holder does not receive new Notes on the date of the exchange that may be
      sold without restriction under state and federal securities laws (other
      than due solely to the status of such holder as an affiliate of ours or
      Qwest within the meaning of the Securities Act or as a broker-dealer);

then in each case, we or Qwest will promptly deliver to the holders written
notice thereof; and at our or Qwest's sole expense:

    - as promptly as practicable (but in no event more than 90 days after so
      required or requested pursuant to the Registration Rights Agreement),
      file a shelf registration statement covering resales of the old Notes (the
      "Shelf Registration Statement");

    - use our reasonable best efforts to cause the Shelf Registration Statement
      to be declared effective under the Securities Act as soon as practicable;
      and

    - use our reasonable best efforts to keep effective the Shelf Registration
      Statement until the earlier of two years (or, if Rule 144(k) is amended to
      provide a shorter restrictive period, such shorter period) after the
      closing date or such time as all of the applicable old Notes have been
      sold thereunder.

    We or Qwest will, if a Shelf Registration Statement is filed, provide to
each holder copies of the prospectus that is a part of the Shelf Registration
Statement, notify each such holder when the Shelf Registration Statement for the
Notes has become effective and take certain other actions as are required to
permit unrestricted resales of the old Notes. A holder that sells old Notes
pursuant to the Shelf Registration Statement will be required to be named as a
selling security holder in the related prospectus, to provide information
related thereto and to deliver such prospectus to purchasers, will be subject to
certain of the civil liability provisions under the Securities Act in connection
with such sales and will be bound by the provisions of the Registration Rights
Agreement that are applicable to such a holder (including certain
indemnification rights and obligations). Neither we nor Qwest will have any
obligation to include in the Shelf Registration Statement holders who do not
deliver such information to us or Qwest.

    If we or Qwest fail to comply with certain provisions of the Registration
Rights Agreement, in each case as described below, then a special interest
premium (the "Special Interest Premium") will become payable in respect of the
old Notes.

    If:

    - the Exchange Offer Registration Statement is not filed with the SEC on or
      before the 150th calendar day following February 14, 2001 (or by July 13,
      2001);

    - the Exchange Offer Registration Statement is not declared effective on or
      before the 210th calendar day following February 14, 2001 (or by
      September 12, 2001); or

    - the exchange offer is not consummated or the Shelf Registration Statement
      is not declared effective on or before the 240th calendar day following
      February 14, 2001 (or by October 12, 2001);

the Special Interest Premium will accrue in respect of the old 7.25% Notes or
the old 7.75% Notes, as the case may be, from and including the next calendar
day following each of (a) such 150-day period in the case of the first bullet
listed above, (b) such 210-day period in the second bullet listed above and
(c) such 240-day period in the case of the third bullet listed above, in each
case at a rate equal to 0.25% per annum.

    The aggregate amount of the Special Interest Premium in respect of each of
the old 7.25% Notes or the old 7.75% Notes, as the case may be, payable pursuant
to the above provisions, will in no event exceed 0.25% per annum. If the
Exchange Offer Registration Statement is not declared

                                       30

effective on or before the 240th calendar day following February 14, 2001 and we
and Qwest request holders of old 7.25% Notes or the old 7.75% Notes, as the case
may be, to provide the information called for by the Registration Rights
Agreement for inclusion in the Shelf Registration Statement, the old 7.25% Notes
or the old 7.75% Notes, as applicable, owned by holders who do not deliver such
information to us and Qwest when required pursuant to the Registration Rights
Agreement, will not be entitled to any Special Interest Premium for any day
after the 240th day following February 14, 2001.

    Upon:

    - filing of the Exchange Offer Registration Statement after the 150-day
      period described above;

    - effectiveness of the Exchange Offer Registration Statement after the
      210-day period described above; or

    - consummation of the exchange offer or the effectiveness of a Shelf
      Registration Statement, as the case may be, after the 240-day period
      described above;

the interest rate on the old 7.25% Notes or the old 7.75% Notes, as the case may
be, from the day of such filing, effectiveness or consummation, as the case may
be, will be reduced to the applicable original interest rate set forth on the
cover page of this prospectus for the old 7.25% Notes or the old 7.75% Notes.

    If a Shelf Registration Statement is declared effective pursuant to the
foregoing paragraphs, and if we and Qwest fail to keep such Shelf Registration
Statement continuously (a) effective or (b) useable for resales for the period
required by the Registration Rights Agreement due to certain circumstances
relating to pending corporate developments, public filings with the SEC and
similar events, or because the prospectus contains an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary in order to make the statements therein not misleading, and such
failure continues for more than 60 days (whether or not consecutive) in any
twelve-month period (the 61st day being referred to as the "Default Day"), then
from the Default Day until the earlier of:

    - the date that the Shelf Registration Statement is again deemed effective
      or is usable;

    - the date that is the second anniversary of the closing date (or, if
      Rule 144(k) is amended to provide a shorter restrictive period, such
      shorter period); or

    - the date as of which all of the old 7.25% Notes or the old 7.75% Notes, as
      the case may be, are sold pursuant to the Shelf Registration Statement;

the Special Interest Premium in respect of the old 7.25% Notes or the old 7.75%
Notes, as the case may be, will accrue at a rate equal to 0.25% per annum.

    If we or Qwest fail to keep the Shelf Registration Statement continuously
effective or useable for resales pursuant to the preceding paragraph, we or
Qwest will give the holders notice to suspend the sale of the old 7.25% Notes or
the old 7.75% Notes, as applicable, and will extend the relevant period referred
to above during which we or Qwest are required to keep effective the Shelf
Registration Statement (or the period during which Participating Broker-Dealers
are entitled to use the prospectus included in the Exchange Offer Registration
Statement in connection with the resale of new 7.25% Notes or the new 7.75%
Notes, as the case may be) by the number of days during the period from and
including the date of the giving of such notice to and including the date when
holders will have received copies of the supplemented or amended prospectus
necessary to permit resales of the old Notes or to and including the date on
which we or Qwest have given notice that the sale of the old Notes may be
resumed, as the case may be.

                                       31

    Each old Note contains a legend to the effect that the holder thereof, by
its acceptance thereof, will be deemed to have agreed to be bound by the
provisions of the Registration Rights Agreement.

    The Registration Rights Agreement is governed by, and construed in
accordance with, the laws of the State of New York. This summary of certain
provisions of the Registration Rights Agreement does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, all the
provisions of the Registration Rights Agreement, a form of which is available
upon request to us or Qwest. In addition, the information set forth above
concerning certain interpretations and positions taken by the Staff is not
intended to constitute legal advice, and prospective investors should consult
their own legal advisors with respect to such matters.

                    CERTAIN U.S. FEDERAL TAX CONSIDERATIONS

    The following discussion summarizes certain U.S. federal tax consequences of
an exchange of old Notes for new Notes in the exchange offer and the purchase,
beneficial ownership and disposition of new Notes. For purposes of this summary,
a "U.S. Holder" means a beneficial owner of an old Note or a new Note that is
for U.S. federal income tax purposes:

    - an individual who is a citizen or resident of the United States;

    - a corporation, partnership or other business entity created or organized
      under the laws of the United States or any state thereof (including the
      District of Columbia);

    - an estate the income of which is subject to U.S. federal income taxation
      regardless of its source; or

    - a trust with respect to which a court within the United States is able to
      exercise primary supervision over its administration, and one or more
      United States persons have the authority to control all of its substantial
      decisions.

    An individual may, subject to certain exceptions, be deemed to be a resident
of the United States by reason of being present in the United States for at
least 31 days in the calendar year and for an aggregate of at least 183 days
during a three-year period ending in the current calendar year (counting for
such purposes all the days present in the current year, one-third of the days
present in the immediately preceding year, and one-sixth of the days present in
the second preceding year). A "Non-U.S. Holder" is a beneficial owner of an old
Note or a new Note that is not a U.S. Holder.

    This summary is based on interpretations of the Internal Revenue Code of
1986, as amended (the "Code"), regulations issued thereunder, and rulings and
decisions currently in effect (or in some cases proposed), all of which are
subject to change. Any such change may be applied retroactively and may
adversely affect the federal tax consequences described herein. This summary
addresses only holders that own old Notes or will own new Notes as capital
assets and not as part of a "straddle" or a "conversion transaction" for U.S.
federal income tax purposes or as part of some other integrated investment. This
summary does not discuss all of the tax consequences that may be relevant to
particular investors or to investors subject to special treatment under the U.S.
federal income tax laws (such as life insurance companies, tax-exempt entities,
regulated investment companies, securities dealers, investors in pass-through
entities, and investors whose functional currency is not the U.S. dollar).
Persons considering the exchange of their old Notes for new Notes and persons
considering the purchase of new Notes should consult their tax advisors
concerning the application of U.S. federal tax laws to their particular
situations as well as any consequences of the exchange of the old Notes for new
Notes and of the purchase, beneficial ownership and disposition of new Notes
arising under the laws of any state or other taxing jurisdiction.

U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE OFFER TO U.S. HOLDERS AND
  NON-U.S. HOLDERS

    The exchange of old Notes for new Notes pursuant to the exchange offer will
not be a taxable event for U.S. federal income tax purposes. U.S. Holders and
Non-U.S. Holders will not recognize any taxable gain or loss as a result of such
exchange and will have the same tax basis and holding period in the new Notes as
they had in the old Notes immediately before the exchange.

U.S. FEDERAL INCOME TAX CONSEQUENCES TO U.S. HOLDERS

    TREATMENT OF INTEREST.  Stated interest on the new Notes will be taxable to
U.S. Holders as ordinary interest income as the interest accrues or is paid in
accordance with the holder's regular method of accounting.

    MARKET DISCOUNT.  If a U.S. Holder acquires a new Note for an amount that is
less than its principal amount by more than a DE MINIMIS amount (generally 0.25%
of the principal amount multiplied by the number of remaining whole years to
maturity), the amount of the difference will be treated as "market discount." In
the event a U.S. Holder acquires a new Note with market discount, unless the
U.S. Holder elects to include such market discount in income as it accrues, a
U.S. Holder will be required to treat any principal payment on, and any gain on
the sale, exchange, retirement or other disposition (including a gift) of, a new
Note as ordinary income to the extent of any accrued market discount that has
not previously been included in income. In general, market discount on the new
Notes will accrue ratably over the remaining term of the new Notes or, at the
election of the U.S. Holder, under a constant yield method. In addition, a U.S.
Holder could be required to defer the deduction of all or a portion of the
interest paid on any indebtedness incurred or continued to purchase or carry a
new Note unless the U.S. Holder elects to include market discount in income
currently. Such an election applies to all debt instruments held by a taxpayer
and may not be revoked without the consent of the Internal Revenue Service (the
"IRS").

    AMORTIZATION OF BOND PREMIUM.  A U.S. Holder that purchases a new Note for
an amount in excess of its stated principal amount will be considered to have
purchased the Note at a premium. The U.S. Holder may elect to amortize such
premium (as an offset to interest income), using a constant yield method, over
the remaining term of the new Note (or to an earlier call date if it results in
a smaller amount of amortizable bond premium). Such election, once made,
generally applies to all debt instruments held or subsequently acquired by the
U.S. Holder on or after the first day of the first taxable year to which such
election applies and may be revoked only with the consent of the IRS. A U.S.
Holder that elects to amortize such premium must reduce its tax basis in the
related Note by the amount of the premium amortized during its holding period.
If a U.S. Holder does not elect to amortize the premium, the amount of such
premium will be included in the U.S. Holder's tax basis for purposes of
computing gain or loss in connection with a taxable disposition of the new Note.

SALE OR OTHER DISPOSITION OF NEW NOTES

    In general, upon the sale, retirement or other taxable disposition of a new
Note, a U.S. Holder will recognize taxable gain or loss equal to the difference
between (i) the amount of the cash and the fair market value of any property
received on the sale, retirement or other taxable disposition (not including any
amount attributable to accrued but unpaid interest or accrued market discount
not previously included in income) and (ii) the U.S. Holder's adjusted tax basis
in the new Note. A U.S. Holder's adjusted tax basis in a new Note generally will
be equal to the cost of the Note to such U.S. Holder, increased by the amount of
any market discount previously included in income by the U.S. Holder and reduced
by the amount of any payments received by the U.S. Holder, other than payments
of qualified stated interest, and by the amount of amortizable bond premium
taken

                                       33

into account. Subject to the discussion of market discount above, gain or loss
realized on the sale, retirement or other taxable disposition of a new Note will
be capital gain or loss.

U.S. FEDERAL INCOME AND ESTATE TAX CONSEQUENCES TO NON-U.S. HOLDERS OF OWNERSHIP
  OF NEW NOTES

    For purposes of the following summary, interest and gain on the sale,
exchange or other disposition of a new Note will be considered "U.S. trade or
business income" if such income or gain is:

    - effectively connected with the conduct of a trade or business in the
      United States; or

    - in the case of a treaty resident, attributable to a permanent
      establishment (or, in the case of an individual, to a fixed base) in the
      United States.

    TREATMENT OF INTEREST.  A Non-U.S. Holder that is not subject to U.S.
federal income tax as a result of any direct or indirect connection to the
United States other than its ownership of a new Note will not be subject to U.S.
federal income or withholding tax in respect of interest income on the new Note
if:

    - the interest is not U.S. trade or business income;

    - the Non-U.S. Holder provides an appropriate statement on IRS Form W-8BEN,
      together with all appropriate attachments, signed under penalties of
      perjury, identifying the Non-U.S. Holder and stating, among other things,
      that the Non-U.S. Holder is not a United States person for U.S. federal
      income tax purposes; and

    - the Non-U.S. Holder is not a "10-percent shareholder," a "related
      controlled foreign corporation" with respect to us as specially defined
      for U.S. federal income tax purposes, or a bank whose receipt of interest
      on the new Notes is described in Section 881(c)(3)(A) of the Code.

    If a new Note is held through a securities clearing organization or certain
other financial institutions, the organization or institution may provide a
signed statement to eliminate withholding tax. However, in such case, the signed
statement must be accompanied by a copy of the IRS Form W-8BEN or the substitute
form provided by the beneficial owner to the organization or institution. A
Non-U.S. Holder that is treated as a partnership for U.S. federal tax purposes
generally will be required to provide an IRS Form W-8IMY and to attach an
appropriate certification by each beneficial owner of the Non-U.S. Holder
(including in certain cases, such beneficial owner's beneficial owners).
Prospective investors, including foreign partnerships and their partners, should
consult their tax advisors regarding these possible additional reporting
requirements.

    To the extent these conditions are not met, a 30% withholding tax will apply
to interest income on the new Note, unless an income tax treaty reduces or
eliminates such tax or unless the interest is U.S. trade or business income with
respect to such Non-U.S. Holder and the Non-U.S. Holder provides an appropriate
statement to that effect. In the latter case, such Non-U.S. Holder generally
will be subject to U.S. federal income tax with respect to all income from the
new Notes at regular rates applicable to U.S. taxpayers. Additionally, in such
event, Non-U.S. Holders that are corporations could be subject to a branch
profits tax on such income.

    TREATMENT OF DISPOSITIONS OF NEW NOTES.  In general, a Non-U.S. Holder will
not be subject to U.S. federal income tax on any amount received (other than
amounts in respect of accrued but unpaid interest) upon retirement or
disposition of a new Note unless such Non-U.S. Holder is an individual present
in the United States for 183 days or more in the taxable year of the sale,
exchange or other disposition and certain other requirements are met, or unless
the gain is U.S. trade or business income. In the latter event, Non-U.S. Holders
generally will be subject to U.S.

                                       34

federal income tax with respect to such gain at regular rates applicable to U.S.
taxpayers. Additionally, in such event, Non-U.S. Holders that are corporations
could be subject to a branch profits tax on such gain.

    TREATMENT OF NEW NOTES FOR U.S. FEDERAL ESTATE TAX PURPOSES.  An individual
Non-U.S. Holder (who is not domiciled in the United States for U.S. federal
estate tax purposes at the time of death) will not be subject to U.S. federal
estate tax in respect of a new Note, so long as the Non-U.S. Holder is not a
"10-percent shareholder" with respect to us as specially defined for U.S.
federal income tax purposes and payments of interest on such new Note would not
have been considered U.S. trade or business income at the time of such Non-U.S.
Holder's death.

U.S. INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING TAX

    Under certain circumstances, the Code requires "information reporting"
annually to the IRS and to each holder of new Notes, and "backup withholding" at
a rate of 31% with respect to certain payments made on or with respect to the
new Notes. Backup withholding generally does not apply with respect to certain
holders of new Notes, including corporations, tax-exempt organizations,
qualified pension and profit sharing trusts and individual retirement accounts.

    A U.S. Holder may be subject to backup withholding unless such U.S. Holder
provides an IRS Form W-9, signed under penalties of perjury, identifying the
U.S. Holder, providing such U.S. Holder's taxpayer identification number and
certifying such U.S. Holder is not subject to backup withholding.

    A Non-U.S. Holder that provides an IRS Form W-8BEN, together with all
appropriate attachments, signed under penalties of perjury, identifying the
Non-U.S. Holder and stating that the Non-U.S. Holder is not a United States
person, will not be subject to IRS reporting requirements and U.S. backup
withholding. IRS Forms W-8BEN will generally be required from the beneficial
owners of interests in a Non-U.S. Holder that is treated as a partnership for
U.S. federal income tax purposes.

    The payment of the proceeds on the disposition of a new Note to or through
the U.S. office of a broker generally will be subject to information reporting
and backup withholding at a rate of 31% unless the Non-U.S. Holder either
certifies its status as a Non-U.S. Holder under penalties of perjury on IRS
Form W-8BEN (as described above) or otherwise establishes an exemption. The
Economic Growth and Tax Relief Reconciliation Act of 2001, signed into law on
June 7, 2001, will reduce the backup withholding tax rate from 31% to 30.5% for
payments made after August 6, 2001. The backup withholding tax rate will then be
gradually reduced each year until 2006, when the backup withholding rate will be
28%.

    The payment of the proceeds on the disposition of a new Note by a Non-U.S.
Holder to or through a non-U.S. office of a non-U.S. broker will not be subject
to backup withholding or information reporting unless the non-U.S. broker is a
"U.S. related person" (as defined below). The payment of proceeds on the
disposition of a new Note by a Non-U.S. Holder to or through a non-U.S. office
of a U.S. broker or a U.S. related person generally will not be subject to
backup withholding but will be subject to information reporting unless the
Non-U.S. Holder certifies its status as a Non-U.S. Holder under penalties of
perjury or the broker has certain documentary evidence in its files as to the
Non-U.S. Holder's foreign status and the broker has no actual knowledge to the
contrary.

    For this purpose, a "U.S. related person" is:

    - a "controlled foreign corporation" as specially defined for U.S. federal
      income tax purposes;

                                       35

    - a foreign person 50% or more of whose gross income from all sources for
      the three-year period ending with the close of its taxable year preceding
      the payment (or for such part of the period that the broker has been in
      existence) is derived from activities that are effectively connected with
      the conduct of a U.S. trade or business; or

    - a foreign partnership if at any time during its tax year one or more of
      its partners are United States persons who, in the aggregate, hold more
      than 50% of the income or capital interest of the partnership or if, at
      any time during its taxable year, the partnership is engaged in the
      conduct of a U.S. trade or business.

    Backup withholding is not an additional tax and may be refunded (or credited
against the holder's U.S. federal income tax liability, if any), provided that
certain required information is furnished. The information reporting
requirements may apply regardless of whether withholding is required. Copies of
the information returns reporting such interest and withholding also may be made
available to the tax authorities in the country in which a Non-U.S. Holder is a
resident under the provisions of an applicable income tax treaty or agreement.

                              PLAN OF DISTRIBUTION

    Each Participating Broker-Dealer that receives new Notes for its own account
in the exchange offer must acknowledge that it acquired the old Notes for its
own account as a result of market-making or other trading activities and must
agree that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of the new Notes. The letter of
transmittal states that by so acknowledging and by delivering a prospectus, a
Participating Broker-Dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. See "REGISTRATION
RIGHTS." A Participating Broker-Dealer may use this prospectus, as it may be
amended or supplemented from time to time, in connection with resales of new
7.25% Notes or new 7.75% Notes received in exchange for old 7.25% Notes or old
7.75% Notes, respectively, where the old 7.25% Notes or the old 7.75% Notes, as
the case may be, were acquired as a result of market-making activities or other
trading activities. Under the Registration Rights Agreement, we and Qwest have
agreed that for a period of 240 calendar days after the expiration date, we will
make this prospectus, as amended or supplemented, available to any Participating
Broker-Dealer for use in connection with any resale of new Notes.

    We will not receive any proceeds from any sale of the new Notes by any
Participating Broker-Dealer. New Notes received by Participating Broker-Dealers
for their own account in the exchange offer may be sold from time to time in one
or more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the new 7.25% Notes or the new 7.75% Notes, as
the case may be, or a combination of the methods of resale, at market prices
prevailing at the time of resale, at prices related to the prevailing market
prices or negotiated prices. Any resale may be made directly to purchasers or to
or through brokers or dealers who may receive compensation in the form of
commissions or concessions from any such Participating Broker-Dealer and/or the
purchasers of the new Notes. Any Participating Broker-Dealer that resells new
Notes that were received by it for its own account in the exchange offer and any
broker or dealer that participates in a distribution of the new Notes may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any resale of new Notes and any commissions or concessions received by
those persons may be deemed to be underwriting compensation under the Securities
Act. The letter of transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a Participating Broker-Dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

    For a period of 240 calendar days after closing of the exchange offer, we
will promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any

                                       36

Participating Broker-Dealer that requests the documents in the letter of
transmittal. We have agreed to pay all expenses incident to our or Qwest's
performance of, or compliance with, the Registration Rights Agreement and all
expenses incident to the exchange offer, including the expenses of one counsel
for the holders of the old Notes, but excluding commissions or concessions of
any brokers or dealers, and will indemnify the holders, including any
broker-dealers, and certain parties related to the holders against certain
liabilities, including liabilities under the Securities Act.

    We have not entered into any arrangements or understandings with any person
to distribute the new Notes to be received in the exchange offer.

                                    PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 145 of the Delaware General Corporation Law (the "DGCL") permits the
board of directors of Qwest Communications International Inc. ("Qwest") to
indemnify any person against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlements actually and reasonably incurred by him or
her in connection with any threatened, pending or completed action, suit or
proceeding in which such person is made a party by reason of his or her being or
having been a director, officer, employee or agent of Qwest, in terms
sufficiently broad to permit such indemnification under certain circumstances
for liabilities (including reimbursement for expenses incurred) arising under
the Securities Act of 1933, as amended (the "Securities Act"). The statute
provides that indemnification pursuant to its provisions is not exclusive of
other rights of indemnification to which a person may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors, or otherwise.

    Qwest's Restated Certificate of Incorporation and Bylaws provide for
indemnification of its directors and officers to the fullest extent permitted by
law.

    As permitted by section 102 of the DGCL, Qwest's Restated Certificate of
Incorporation eliminates a director's personal liability for monetary damages to
Qwest and its stockholders arising from a breach or alleged breach of a
director's fiduciary duty except for liability under section 174 of the DGCL,
for liability for any breach of the director's duty of loyalty to Qwest or its
stockholders, for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law or for any transaction from
which the director derived an improper personal benefit.

    The Registrant's Bylaws provide for the indemnification of directors and
officers to the extent permissible under applicable law. Section 7-109-102 of
the Colorado Business Corporation Act (the "CBCA") specifies the circumstances
under which a corporation may indemnify its directors, officers, employees or
agents. For acts done in a person's "official capacity," the CBCA generally
requires that an act be done in good faith and in a manner reasonably believed
to be in the best interests of the corporation. In all other civil cases, the
person must have acted in good faith and in a way that was not opposed to the
corporation's best interests. In criminal actions or proceedings, the CBCA
imposes an additional requirement that the actor had no reasonable cause to
believe his conduct was unlawful. In any proceeding by or in the right of the
corporation, or charging a person with the improper receipt of a personal
benefit, no indemnification, except for court-ordered indemnification for
reasonable expenses occurred, can be made. Indemnification is mandatory when any
director or officer is wholly successful, on the merits or otherwise, in
defending any civil or criminal proceeding. The rights granted by the Bylaws
will not be deemed exclusive of any other rights to which those seeking
indemnification, contribution, or advancement of expenses may be entitled under
any statute, certificate or articles of incorporation, agreement, contract of
insurance, vote of shareholders or disinterested directors, or otherwise. The
rights of indemnification and advancement of expenses provided by or granted
pursuant to the Bylaws will continue as to a person who has ceased to be an
indemnified representative in respect of matters arising before such time and
will inure to the benefit of the heirs, executors, administrators, and personal
representatives of such a person.

    The directors and officers of Qwest and Registrant are covered by insurance
policies indemnifying against certain liabilities, including certain liabilities
arising under the Securities Act which might be incurred by them in such
capacities and against which they cannot be indemnified by or on behalf of Qwest
or Registrant.

                                      II-1

    The agents, dealers or underwriters who executed the agreements filed as
Exhibit 1 to this registration statement agreed to indemnify Qwest and
Registrant directors and their officers who signed the registration statement
against certain liabilities which might arise under the Securities Act with
respect to information furnished to Qwest and Registrant by or on behalf of any
such indemnifying party.

ITEM 22.  UNDERTAKINGS.

    (a) The undersigned hereby undertakes:

        (1) That before any public reoffering of the securities registered
    hereunder through use of a prospectus which is a part of this registration
    statement, by any person or party who is deemed to be an underwriter within
    the meaning of Rule 145(c) under the Securities Act, the issuer undertakes
    that such reoffering prospectus will contain the information called for by
    the

                                      II-2

    applicable registration form with respect to reofferings by persons who may
    be deemed underwriters, in addition to the information called for by the
    other items of the applicable form.

        (2) That every prospectus (i) that is filed pursuant to paragraph (1)
    immediately preceding, or (ii) that purports to meet the requirements of
    section 10(a)(3) of the Securities Act and is used in connection with an
    offering of securities subject to Rule 415 under the Securities Act, will be
    filed as a part of an amendment to the registration statement and will not
    be used until such amendment is effective, and that, for purposes of
    determining any liability under the Securities Act, each such post-effective
    amendment will be deemed to be a new registration statement relating to the
    securities offered therein, and the offering of such securities at that time
    will be deemed to be the initial bona fide offering thereof.

    (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
(the "Commission") such indemnification is against public policy as expressed in
the Securities Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceedings) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

    (c) The undersigned hereby undertakes to respond to requests for information
that is incorporated by reference into the prospectus pursuant to Items 4,
10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.

    (d) The undersigned hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.

    (e) The undersigned hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the registrant's annual
report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934
(and, where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the registration statement will be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time will be deemed to be the initial bona
fide offering thereof.

    (f)  The undersigned hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:

           (i)  to include any prospectus required by Section 10(a)(3) of the
       Securities Act;

           (ii) to reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement. Notwithstanding the foregoing, any increase
       or decrease

                                      II-3

       in volume of securities offered (if the total dollar value of securities
       offered would not exceed that which was registered) and any deviation
       from the low or high end of the estimated maximum offering range may be
       reflected in the form of prospectus filed with the Commission pursuant to
       Rule 424(b) if, in the aggregate, the changes in volume and price
       represent no more than a 20 percent change in the maximum aggregate
       offering price set forth in the "Calculation of Registration Fee" table
       in the effective registration statement; and

           (iii) to include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment will be deemed to be a
    new registration statement relating to the securities offered therein, and
    the offering of such securities at that time will be deemed to be the
    initial bona fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

        (4) For purposes of determining any liability under the Securities Act,
    each filing of the Registrant's annual report pursuant to Section 13(a) or
    Section 15(d) of the Exchange Act that is incorporated by reference in the
    registration statement will be deemed to be a new registration statement
    relating to the securities offered therein, and the offering of such
    securities at that time will be deemed to be the initial bona fide offering
    thereof.

                                      II-4
