	Significant Accounting and Reporting Policies
	Basis of Presentation
	Any reference in this report to "TransUnion," "TransUnion Holding," the “Company,” “we,” “us,” and “our” refers to TransUnion Holding Company, Inc. (“TransUnion") and its direct and indirect subsidiaries, including TransUnion Corp. ("TransUnion Corp").
	The accompanying unaudited consolidated financial statements of TransUnion have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. In the opinion of management, all adjustments, including normal recurring adjustments, considered necessary for a fair presentation have been included. All significant intercompany transactions and balances have been eliminated. The operating results of TransUnion for the periods presented are not necessarily indicative of the results that may be expected for the full year ending December 31, 2014. These unaudited consolidated financial statements should be read in conjunction with our audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2013, filed with the Securities and Exchange Commission (“SEC”) on February 27, 2014.
	Principles of Consolidation
	Investments in unconsolidated entities in which the Company has at least a 20% ownership interest, or where it is able to exercise significant influence, are accounted for using the equity method. Nonmarketable investments in unconsolidated entities in which the Company has less than a 20% ownership interest, or where it is not able to exercise significant influence, are accounted for using the cost method and periodically reviewed for impairment.
	Subsequent Events
	Events and transactions occurring through the date of issuance of the financial statements have been evaluated by management and, when appropriate, recognized or disclosed in the financial statements or notes to the financial statements. See Note 13, "Subsequent Events" for information about our debt refinancing transaction occurring after the balance sheet date.
	Recently Adopted Accounting Pronouncements
	On July 18, 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exist. ASU 2013-11 provides guidance on the presentation of unrecognized tax benefits to better reflect the manner in which an entity would settle at the reporting date any income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses or tax credit carryforwards exist. The objective of ASU 2013-11 is to eliminate the diversity in practice of how companies present unrecognized tax benefits under these circumstances. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. This guidance was adopted by the Company effective January 1, 2014, and did not result in a material change to the Company’s consolidated financial statements. See Note 10, "Income Taxes," for further details regarding the impact of this adoption.

Business Combination [Abstract]	'
Business Combination Disclosure [Text Block]	'
	Business Combination
	On December 16, 2013, we acquired a 100% ownership interest in certain net assets of TLO, LLC ("TLO") for $153.4 million in cash. TLO provides data solutions for identity authentication, fraud prevention, and debt recovery. The Company established a newly incorporated entity, TransUnion Risk and Alternative Data Solutions, Inc. ("Alternative Data") to purchase the net assets of TLO. The results of operations of this business have been included as part of the USIS segment in the accompanying consolidated statements of income since the date of acquisition.
	Purchase Price Allocation
	The allocation of the purchase price is preliminary pending our review of the valuation of intangible assets and goodwill, which is expected to be completed during the second quarter of 2014. The preliminary fair value of the assets acquired and liabilities assumed as of March 31, 2014, consisted of the following:
	(in millions)		Fair Value
	Other current assets		$	0.3
	Property and equipment		6.8
	Identifiable intangible assets		83.4
	Goodwill(1)		68.7
	Total assets acquired		$	159.2
	Total liabilities assumed		(5.8		)
	Net assets of acquired company		$	153.4
	(1)	All of the goodwill is deductible for tax purposes.
	The excess of the purchase price over the preliminary fair value of the net assets acquired was recorded as goodwill. The purchase price of TLO exceeded the fair value of the net assets acquired due primarily to growth opportunities, synergies associated with its internal use software and our existing customer base and brand name, and other technological and operations synergies. Goodwill has been allocated to the USIS segment.
	Identifiable Intangible Assets
	The preliminary fair values of the intangible assets acquired consisted of the following:
	(in millions)		Fair Value			Estimated Useful Life
	Technology and software		$	44.7		10 years
	Trade names and trademarks		13.2			20 years
	Customer relationships		25.5			15 years
	Total identifiable intangible assets		$	83.4
	The weighted-average useful life of identifiable intangible assets is approximately 13.1 years.
	Acquisition Costs
	During 2013, the Company incurred $3.7 million of acquisition-related costs for this acquisition, including banking fees, legal fees, due diligence and other external costs, which were expensed and recorded in other income and expense in the fourth quarter of 2013. Additional acquisition-related costs of $0.3 million were incurred and expensed during the first quarter of 2014.

	Total	$	(3.4	)	$	—	$	(1.2	)	$	(2.2	)
	Level 1 instruments consist of exchange-traded mutual funds and publicly traded equity investments valued at their current market prices, with unrealized gains and losses included in net income. These securities relate to a nonqualified deferred compensation plan held in trust for the benefit of plan participants and are included in other marketable securities on our balance sheet. There were no significant realized or unrealized gains or losses for these securities for any of the periods presented.
	Level 2 instruments consist of interest rate swaps that are further discussed in Note 9, “Debt.” We determined the fair value of the interest rate swaps using standard valuation models with market-based observable inputs including forward and spot exchange rates and interest rate curves. The total fair value of the swap instruments as of March 31, 2014, was a liability of $1.2 million and was included in other liabilities on our consolidated balance sheet. The net of tax unrealized loss on the swap instruments as of March 31, 2014, of $0.7 million was included in accumulated other comprehensive income (loss).
	Level 3 instruments consist of contingent obligations owed to the sellers of e-Scan Data Systems, Inc. (“eScan”), an entity we acquired in 2013. The fair value was determined based on an income approach, using the expected earnings of eScan, and will be assessed each reporting period. The obligation has a maximum payout of $17.0 million, contingent upon eScan meeting certain performance requirements in future years, but is currently valued at $2.2 million. Any remeasurements of the fair value of this contingent obligation prior to payout will result in a gain or loss reflected in our consolidated statements of income.

	The decrease in deferred income tax assets of $17.0 million was due primarily to a reclassification of a portion of our NOL carryforward deferred tax asset from current to noncurrent and an offset for our unrecognized tax benefit results from the adoption of ASU 2013-11 as discussed in Note 1, "Significant Accounting and Reporting Policies."

	Investments in Affiliated Companies
	Investments in affiliated companies represent our investment in non-consolidated domestic and foreign entities. These entities are in businesses similar to ours, such as credit reporting, credit scoring and credit monitoring services. These investments are included in other assets on the balance sheet.
	We use the equity method to account for investments in affiliates where we have at least a 20% ownership interest or where we are able to exercise significant influence. For these investments, we adjust the carrying value for our proportionate share of the affiliates’ earnings, losses and distributions, as well as for purchases and sales of our ownership interest.
	We use the cost method to account for all other nonmarketable investments. For these investments, we adjust the carrying value for purchases and sales of our ownership interests.
	For all investments, we adjust the carrying value if we determine that an other-than-temporary impairment in value has occurred. There were no impairments of investments in affiliated companies taken in the three months ended March 31, 2014 or 2013.
	Investments in affiliated companies consisted of the following:

	Total cost method investments	7.9		7.9
	Total investments in affiliated companies	$	132.7	$	92.4
	Our equity method investments increased during the first quarter of 2014 primarily as a result of our increased ownership interest in CIBIL as discussed in Note 5.

The credit facility was amended and restated on April 9, 2014 as discussed in Note 12, "Subsequent Event."
	During the first quarter of 2014, the Company borrowed $28.5 million on its revolving line of credit to partially fund the purchase of additional equity in CIBIL as discussed in Note 5, "Other Assets," and Note 6, "Investments in Affiliated Companies," and to pay certain administrative costs.
	On April 30, 2012, we entered into swap agreements that effectively fixed the interest payments on a portion of the term loan at 2.033%, plus the applicable margin, beginning March 28, 2013. Under the swap agreements, which we have designated as cash flow hedges, we pay a fixed rate of interest of 2.033% and receive a variable rate of interest equal to the greater of 1.50% or the three month LIBOR. The net amount to be paid or received is recorded as an adjustment to interest expense. The total fair value of the swap instruments as of March 31, 2014, was a liability of $1.2 million and was included in other liabilities on our consolidated balance sheet. The net of tax unrealized loss on the swap instruments as of March 31, 2014, of $0.7 million was included in accumulated other comprehensive income (loss). For the three months ended March 31, 2014, there was no ineffectiveness recorded in the statement of income. In connection with the April 9, 2014, amendment and restatement of the senior secured credit facility, the Company does not expect the current hedge to be highly effective and therefore it will no longer qualify for hedge accounting. Accordingly, the $0.7 million net of tax unrealized loss on the swap recorded in accumulated other comprehensive income will be amortized straight line from April 9, 2014, through December 29, 2017, the end of the swap period.
	11.375% Notes
	Trans Union LLC and its wholly-owned subsidiary TransUnion Financing Corporation issued $645.0 million principal amount of 11.375% senior unsecured notes ("11.375% notes") due June 15, 2018, in a private placement to certain investors. Pursuant to an exchange offer completed in April 2011, these notes were subsequently registered with the SEC. As a result of the 2012 Change in Control Transaction as defined in our Annual Report on Form 10-K for the year ended December 31, 2013, a purchase accounting fair value adjustment increase of $124.2 million was allocated to the 11.375% notes. For further discussion related to the 11.375% notes, see Note 12, Subsequent Events.
	9.625% Notes
	On March 21, 2012, the Company issued $600.0 million principal amount of 9.625%/10.375% senior unsecured PIK toggle notes (“9.625% notes”) due June 15, 2018, in a private placement to certain investors. Pursuant to an exchange offer completed in October 2012, these notes were subsequently registered with the SEC. The Company is required to pay interest on the 9.625% notes in cash unless certain conditions described in the indenture governing the notes are satisfied, in which case the Company will be entitled to pay interest for such period by increasing the principal amount of the notes or by issuing new notes (such increase being referred to as “PIK,” or paid-in-kind interest) to the extent described in the indenture.
	The indenture governing the 9.625% notes contains nonfinancial covenants that include restrictions on our ability to pay dividends or distributions, repurchase equity, prepay junior debt, make certain investments, incur additional debt, issue certain stock, incur liens on property, merge, consolidate or sell certain assets, enter into transactions with affiliates, and allow to exist certain restrictions on the ability of subsidiaries to pay dividends or make other payments to TransUnion Holding. We are in compliance with all covenants under the indenture.
	8.125% Notes
	On November 1, 2012, the Company issued $400.0 million principal amount of 8.125%/8.875% senior unsecured PIK toggle notes (“8.125% notes”) due June 15, 2018, at an offering price of 99.5% in a private placement to certain investors. Pursuant to an exchange offer completed in August 2013, these notes were subsequently registered with the SEC. The Company is required to pay interest on the 8.125% notes in cash unless certain conditions described in the indenture governing the notes are satisfied, in which case the Company will be entitled to pay interest for such period by increasing the principal amount of the notes or by issuing new notes to the extent described in the indenture.
	The indenture governing the 8.125% notes and the nonfinancial covenants are substantially identical to those governing the 9.625% notes. We are in compliance with all covenants under the indenture.
	Fair Value of Debt
	The estimated fair values of our 9.625%, 8.125% and 11.375% notes as of March 31, 2014, were $638.3 million, $419.5 million and $695.0 million, respectively, compared to book values of $600.0 million, $398.4 million and $736.4 million, respectively. The fair value of these fixed-rate notes, as determined under Level 2 of the fair-value hierarchy, is measured using quoted market prices of these publicly traded securities. The book value of our variable-rate debt approximates its fair value. The estimated fair value of our debt may not represent the actual settlement value due to redemption premiums and prepayment penalties that we may incur in connection with extinguishing our debt before its stated maturity.

Income Taxes	'
	Income Taxes
	Over the last three years, what is referred to as the “look-through rule” exception has been allowed to expire and has been retroactively reinstated, which has impacted TransUnion’s effective tax rate. The Internal Revenue Code requires U.S. corporate shareholders to recognize current U.S. taxable income from passive income, such as dividends earned, at certain foreign subsidiaries regardless of whether that income is remitted to the U.S. The look-through rule provides an exception to this recognition for subsidiary passive income attributable to an active business. When the look-through rule is not in effect, we are required under ASC 740-30 to accrue a tax liability for certain foreign earnings as if those earnings were distributed.
	For the three months ended March 31, 2014, we reported a loss before income taxes and an effective tax rate benefit of 0.7%. The effective tax rate was lower than the 35% U.S. federal statutory rate due primarily to the expiration of the look-through rule effective January 1, 2014, and the application of ASC 740-30 to our unremitted foreign earnings, along with a change in state tax rates.
	For the three months ended March 31, 2013, we reported a loss before income taxes and an effective tax rate benefit of 15.3%. The effective tax rate was lower than the 35% U.S. federal statutory rate due primarily to the retroactive reinstatement of the look-through rule effective January 1, 2013, and a change in state tax rates, partially offset by a reduced rate of tax on our foreign earnings.
	The total amount of unrecognized tax benefits was $4.6 million as of both March 31, 2014, and December 31, 2013, and these same amounts would affect the effective tax rate, if recognized, as of those respective dates. A majority of the unrecognized tax benefit as of March 31, 2014, was presented in the balance sheet as a reduction to a deferred tax asset for a net operating loss carryforward under ASU 2013-11 that was adopted effective January 1, 2014. The accrued interest payable for taxes as of both March 31, 2014, and December 31, 2013, was $0.7 million. There was no significant liability for tax penalties as of March 31, 2014, or December 31, 2013. We are regularly audited by federal, state and foreign taxing authorities and, given the uncertainties inherent in the audit process, it is reasonably possible that certain audits could result in a significant increase or decrease in the total amounts of unrecognized tax benefits.

Segment Reporting [Abstract]	'
Operating Segments	'
	Operating Segments
	Operating segments are businesses for which separate financial information is available and evaluated regularly by the chief operating decision maker in deciding how to allocate resources. This segment financial information is reported on the basis that is used for the internal evaluation of operating performance. The accounting policies of the segments are the same as described in Note 1, “Significant Accounting and Reporting Policies.”
	We evaluate the performance of segments based on revenue and operating income. Intersegment sales and transfers have been eliminated and were not material.
	The following is a more detailed description of the three operating segments and the Corporate unit, which provides support services to each operating segment:
	U.S. Information Services
	U.S. Information Services (“USIS”) provides consumer reports, credit scores, identity authentication and verification services, analytical services and decisioning technology to businesses in the United States through both direct and indirect channels. These services are offered to customers in the financial services, insurance, healthcare and other markets. These business customers use our products and services to acquire new customers, identify cross-selling opportunities, measure and manage debt portfolio risk, collect debt, manage fraud and determine and collect healthcare payments. This segment also provides mandated consumer services, including dispute investigations, free annual credit reports and other requirements of the United States Fair Credit Reporting Act (“FCRA”), the Fair and Accurate Credit Transactions Act of 2003 (“FACTA”), and other credit-related legislation.
	International
	The International segment provides services similar to our USIS segment to business customers outside the United States and automotive information and commercial data services to customers in select geographies. Depending on the maturity of the credit economy in each location, services may include credit reports, analytical and decision services, and risk management services. These services are offered to customers in a number of industries, including financial services, insurance, automotive, collections and communications, and are delivered through both direct and indirect channels. The International segment also provides consumer services similar to those offered in our Interactive segment, such as credit reports, credit scores and credit monitoring services. The two market groups in the International segment are developed markets, which includes Canada, Hong Kong and Puerto Rico, and emerging markets, which includes Africa, Latin America, India and other emerging markets in Asia Pacific.
	Interactive
	Interactive provides services to consumers, including credit reports, scores and credit and identity monitoring services, primarily through the internet. The majority of revenue is derived from both direct and indirect subscribers who pay a monthly fee for access to their credit report and score, and for alerts related to changes in their credit reports.
	Corporate
	Corporate provides shared services for the Company and conducts enterprise functions. Certain costs incurred in Corporate that are not directly attributable to one or more of the operating segments remain in Corporate. These costs are typically for enterprise-level functions and are primarily administrative in nature.

	On April 9, 2014, TransUnion Corp. and Trans Union LLC refinanced and amended the senior secured credit facility. The refinancing resulted in an increase of the outstanding term loan from $1,120.5 million to $1,900.0 million. The amendment, among other things, reduced the interest rate floor and margins, reduced the amount available under the revolving line of credit from $210.0 million to $190.0 million, extended the maturity dates, and changed certain covenant requirements. The additional borrowings were used in part to repay all amounts outstanding under the existing revolving line of credit and pay fees and expenses associated with the refinancing transaction. On May 9, 2014, the remaining borrowings will be used to redeem the entire $645.0 million outstanding balance of the 11.375% notes issued by TransUnion Financing Corp and Trans Union LLC including unpaid accrued interest and a prepayment premium. We refer to these transactions collectively as the "2014 Refinancing Transaction." The 2014 Refinancing Transaction is expected to result in a net gain of approximately $30 million that will be recorded in the consolidated statement of income and approximately $9 million of additional deferred financing fees that will be recorded on the balance sheet in the second quarter of 2014.

Principles of Consolidation	'
	Principles of Consolidation
	Investments in unconsolidated entities in which the Company has at least a 20% ownership interest, or where it is able to exercise significant influence, are accounted for using the equity method. Nonmarketable investments in unconsolidated entities in which the Company has less than a 20% ownership interest, or where it is not able to exercise significant influence, are accounted for using the cost method and periodically reviewed for impairment.
Subsequent Events	'
	Subsequent Events
	Events and transactions occurring through the date of issuance of the financial statements have been evaluated by management and, when appropriate, recognized or disclosed in the financial statements or notes to the financial statements.

Recently Adopted Accounting Pronouncements	'
	Recently Adopted Accounting Pronouncements
	On July 18, 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exist. ASU 2013-11 provides guidance on the presentation of unrecognized tax benefits to better reflect the manner in which an entity would settle at the reporting date any income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses or tax credit carryforwards exist. The objective of ASU 2013-11 is to eliminate the diversity in practice of how companies present unrecognized tax benefits under these circumstances. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. This guidance was adopted by the Company effective January 1, 2014, and did not result in a material change to the Company’s consolidated financial statements. See Note 10, "Income Taxes," for further details regarding the impact of this adoption.
