Accounting Policies [Abstract]
Preparation Of Interim Financial Statements	NOTE 1. PREPARATION OF INTERIM FINANCIAL STATEMENTS Basis of Presentation Throughout this document, AT&T Inc. is referred to as “we,” “AT&T” or the “Company.” The consolidated financial statements include the accounts of the Company and subsidiaries and affiliates which we control. AT&T is a holding company whose subsidiaries and affiliates operate worldwide in the telecommunications, media and technology industries. You should read this document in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2021. The results for the interim periods are not necessarily indicative of those for the full year. These consolidated financial statements include all adjustments that are necessary to present fairly the results for the presented interim periods, consisting of normal recurring accruals and other items. On April 8, 2022, we completed the previously announced separation of our WarnerMedia business, which represented substantially all of our WarnerMedia segment except for certain retained assets such as Xandr, in a Reverse Morris Trust transaction, under which Magallanes, Inc. (Spinco), a wholly-owned subsidiary of AT&T that held the WarnerMedia business, was distributed to AT&T stockholders via a pro rata dividend, followed by the combination of Spinco with a subsidiary of Discovery, Inc. (Discovery), which was renamed Warner Bros. Discovery, Inc. (WBD). Each AT&T shareholder was entitled to receive 0.241917 shares of WBD common stock for each share of AT&T common stock held as of the record date, which represented approximately 71% of WBD. (See Notes 8 and 13) As of March 31, 2022, the results of the WarnerMedia business are included in the continuing operations of AT&T for all periods presented herein. With the separation and distribution, the WarnerMedia business will meet the criteria for discontinued operations beginning with our second-quarter 2022 reporting. For discontinued operations, we evaluated transactions completed during 2021 that were components of AT&T’s single plan of a strategic shift, including dispositions that may not have individually met the criteria due to materiality, and have determined discontinued operations to be comprised of WarnerMedia, Vrio, Xandr and Playdemic Ltd. (Playdemic). These businesses will be reflected in our historical financial statements as discontinued operations, including for periods prior to the consummation of the WarnerMedia/Discovery transaction. All significant intercompany transactions are eliminated in the consolidation process. Investments in subsidiaries and partnerships which we do not control but have significant influence are accounted for under the equity method. Earnings from certain investments accounted for using the equity method are included in our results on a one quarter lag. We also record our proportionate share of our equity method investees’ other comprehensive income (OCI) items, including translation adjustments. The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including estimates of probable losses and expenses, that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain prior period amounts have been conformed to the current period’s presentation (see Note 4). In the tables throughout this document, percentage increases and decreases that are not considered meaningful are denoted with a dash. Accounting Policies, Adopted and Pending Accounting Standards and Other Changes Customer Acquisition and Fulfillment Costs During the first quarter of 2022, we updated our analysis of expected economic lives of customer relationships. As of January 1, 2022, we extended the amortization period for deferred acquisition and fulfillment contract costs within Mobility and broadband/fiber in Consumer Wireline and Business Wireline to better reflect the estimated economic lives of the relationships. These changes in accounting estimate decreased other cost of revenues approximately $135, or $0.01 per diluted share, in the first quarter of 2022. Fiber Network Assets During the first quarter of 2022, we updated our analysis of economic lives of AT&T owned fiber network assets. As of January 1, 2022, we extended the estimated economic life and depreciation period of such costs to better reflect the physical life of the assets that we had been experiencing and absence of technological changes that would replace fiber as the best broadband technology in the industry. The change in accounting estimate decreased depreciation expense $70, or $0.01 per diluted share, in the first quarter of 2022. Convertible Instruments As of January 1, 2022, we adopted, through retrospective application, Accounting Standards Update (ASU) No. 2020-06, “Debt—Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (ASU 2020-06). ASU 2020-06 requires that instruments which may be settled in cash or stock are presumed settled in stock in calculating diluted earnings per share. While our intent is to settle the Mobility II preferred interests in cash, the ability to settle this instrument in AT&T shares will result in additional dilutive impact, the magnitude of which is influenced by the fair value of the Mobility II preferred interests and the average AT&T common stock price during the reporting period, which could vary from period-to-period. The following table presents the impact of the adoption of ASU 2020-06 on our diluted earnings per share: Historical Accounting Method Effect of Adoption of ASU 2020-06 1 Under ASU 2020-06 Diluted earnings per share: Three months ended March 31, 2022 $ 0.66 $ (0.01) $ 0.65 Three months ended March 31, 2021 $ 1.04 $ (0.02) $ 1.02 1 See Note 2 for a discussion of the numerator and denominator adjustments. Government Assistance The Financial Accounting Standards Board (FASB) issued ASU No, 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance” (ASU 2021-10), which requires annual disclosures, beginning with the 2022 Annual Report on Form 10-K, in the notes to the financial statements, about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy to other guidance. The annual disclosures include terms and conditions, accounting treatment and impacted financial statement lines reflecting the impact of the transactions. ASU 2021-10 will be effective for annual reporting periods beginning after December 15, 2021, which we plan to adopt under prospective application for all in scope government transactions in the financial statements as of our adoption date or thereafter.

Earnings Per Share	NOTE 2. EARNINGS PER SHARE A reconciliation of the numerators and denominators of basic and diluted earnings per share for the three months ended March 31, 2022 and 2021, is shown in the table below: Three months ended March 31, 2022 2021 Numerators Numerator for basic earnings per share: Net Income Attributable to Common Stock $ 4,762 $ 7,500 Dilutive potential common shares: Mobility II preferred interests 140 140 Share-based payment 6 6 Numerator for diluted earnings per share $ 4,908 $ 7,646 Denominators (000,000) Denominator for basic earnings per share: Weighted average number of common shares outstanding 7,184 7,161 Dilutive potential common shares: Mobility II preferred interests (in shares) 337 294 Share-based payment (in shares) 35 27 Denominator for diluted earnings per share 7,556 7,482 Upon the adoption of ASU 2020-06 in the first quarter of 2022, the ability to settle our Mobility II preferred interests in stock is reflected in our diluted earnings per share calculation. While our intent is to settle the Mobility II preferred interests in cash, the ability to settle this instrument in AT&T shares will result in additional dilutive impact, the magnitude of which is influenced by the fair value of the Mobility II preferred interests and the average AT&T common stock price during the reporting period, which could vary from period-to-period. The numerator includes an adjustment to add back to income the earned distributions on the Mobility II preferred interests, included in net income attributable to noncontrolling interest, and the denominator includes the potential issuance of AT&T common stock to settle the Mobility II preferred interests outstanding.

Segment Reporting [Abstract]
Segment Information	NOTE 4. SEGMENT INFORMATION Our segments are comprised of strategic business units or other operations that offer products and services to different customer segments over various technology platforms and/or in different geographies that are managed accordingly. We analyze our segments based on segment operating contribution, which consists of operating income, excluding acquisition-related costs and other significant items (as discussed below), and equity in net income (loss) of affiliates for investments managed within each segment. We have three reportable segments: (1) Communications, (2) WarnerMedia and (3) Latin America. We also evaluate segment and business unit performance based on EBITDA and/or EBITDA margin, which is defined as operating contribution excluding equity in net income (loss) of affiliates and depreciation and amortization. We believe EBITDA to be a relevant and useful measurement to our investors as it is part of our internal management reporting and planning processes and it is an important metric that management uses to evaluate operating performance. EBITDA does not give effect to depreciation and amortization expenses incurred in operating contribution nor is it burdened by cash used for debt service requirements and thus does not reflect available funds for distributions, reinvestment or other discretionary uses. EBITDA margin is EBITDA divided by total revenues. In the first quarter of 2022, we reclassified into "Corporate" certain administrative costs borne by AT&T where the business units do not influence decision making to conform with the current period presentation. This recast increased Corporate operations and support expenses by approximately $100 in the first quarter of 2021, with a total of $270 for full-year 2021. Correspondingly, this recast lowered administrative expenses at AT&T’s Communications operations, Video and WarnerMedia, with no change on a consolidated basis. The Communications segment provides wireless and wireline telecom and broadband services to consumers located in the U.S. and businesses globally. Our business strategies reflect bundled product offerings that cut across product lines and utilize shared assets. This segment contains the following business units: • Mobility provides nationwide wireless service and equipment. • Business Wireline provides advanced ethernet-based fiber services, IP Voice and managed professional services, as well as traditional voice and data services and related equipment to business customers. • Consumer Wireline provides broadband services, including fiber connections that now provide our multi-gig services to residential customers. Consumer Wireline also provides legacy telephony voice communication services. The WarnerMedia segment develops, produces and distributes feature films, television, gaming and other content in various physical and digital formats globally. WarnerMedia content is distributed through basic networks, Direct-to-Consumer (DTC) or theatrical, TV content and games licensing. Segment results also include Xandr advertising. On April 8, 2022, we completed the separation of our WarnerMedia business, which excluded certain retained assets, such as Xandr, with a subsidiary of Discovery by distribution to AT&T stockholders via a pro rata dividend. On December 21, 2021, we entered into an agreement to sell the marketplace component of Xandr to Microsoft Corporation (Microsoft). (See Notes 8 and 13) The Latin America segment provides wireless services and equipment in Mexico, and prior to the November 2021 disposition of Vrio, video services in Latin America and the Caribbean. Corporate and Other reconciles our segment results to consolidated operating income and income before income taxes. Corporate includes : • DTV stranded costs , which are costs previously allocated to the Video business that were retained after the transaction, net of reimbursements from DIRECTV Entertainment Holdings, LLC (DIRECTV) under transition service agreements. • Parent administration support , which includes costs borne by AT&T where the business units do not influence decision making. • Securitization fees associated with our sales of installment receivables (see Note 9). • Value portfolio , which are businesses no longer integral to our operations or which we no longer actively market. Other items consist of : • Video, which includes our former U.S. video operations that were contributed to DIRECTV on July 31, 2021, and our share of DIRECTV’s earnings as equity in net income of affiliates (see Note 11). • Held-for-sale and other reclassifications, which includes our former Crunchyroll and Government Solutions operations, WarnerMedia film amortization recharacterization, WarnerMedia receivable securitization, and reclassification of parent administrative costs in connection with the separation of Video and WarnerMedia. • Reclassification of prior service credits, which includes the reclassification of prior service credit amortization, where we present the impact of benefit plan amendments in our business unit results. • Merger & Significant Items , which includes items associated with the merger and integration of acquired or divested businesses, including amortization of intangible assets, employee separation charges associated with voluntary and/or strategic offers, asset impairments and abandonments, and other items for which the segments are not being evaluated. • Eliminations and consolidations , removes transactions involving dealings between our segments, including channel distribution between WarnerMedia and Video and Vrio prior to separation, Communications company bundling HBO MAX and, prior to the separation of DIRECTV, includes adjustments for our reporting of the advertising business. “Interest expense” and “Other income (expense) – net,” are managed only on a total company basis and are, accordingly, reflected only in consolidated results.

Deferred Customer Contract Acquisition and Fulfillment Costs Costs to acquire and fulfill customer contracts, including commissions on service activations, for our wireless, business wireline, and consumer wireline services, are deferred and amortized over the contract period or expected customer relationship life, which typically ranges from three years to five years. The following table presents the deferred customer contract acquisition and fulfillment costs included on our consolidated balance sheets: March 31, December 31, Consolidated Balance Sheets 2022 2021 Deferred Acquisition Costs Prepaid and other current assets $ 2,522 $ 2,551 Other Assets 3,541 3,247 Total deferred customer contract acquisition costs $ 6,063 $ 5,798 Deferred Fulfillment Costs Prepaid and other current assets $ 2,436 $ 2,600 Other Assets 4,306 4,148 Total deferred customer contract fulfillment costs $ 6,742 $ 6,748 The following table presents deferred customer contract acquisition and fulfillment cost amortization included in “Other cost of revenue” for the three months ended: March 31, March 31, Consolidated Statements of Income 2022 2021 1 Deferred acquisition cost amortization $ 663 $ 764 Deferred fulfillment cost amortization 664 1,290 1 Includes deferred acquisition amortization of $171 and deferred fulfillment cost amortization of $595 from our separated Video business for the quarter ended March 31, 2021. Contract Assets and Liabilities A contract asset is recorded when revenue is recognized in advance of our right to bill and receive consideration. The contract asset will decrease as services are provided and billed. For example, when installment sales include promotional discounts (e.g., “buy one get one free”) the difference between revenue recognized and consideration received is recorded as a contract asset to be amortized over the contract term. Our contract assets primarily relate to our wireless businesses. Promotional equipment sales where we offer handset credits, which are allocated between equipment and service in proportion to their standalone selling prices, when customers commit to a specified service period result in additional contract assets recognized. These contract assets will amortize over the service contract period, resulting in lower future service revenue. When consideration is received in advance of the delivery of goods or services, a contract liability is recorded. Reductions in the contract liability will be recorded as we satisfy the performance obligations. The following table presents contract assets and liabilities on our consolidated balance sheets: March 31, December 31, Consolidated Balance Sheets 2022 2021 Contract asset $ 4,708 $ 4,518 Current portion in “Prepaid and other current assets” 2,740 2,685 Contract liability 5,586 5,645 Current portion in “Advanced billings and customer deposits” 5,079 5,112 Our contract asset balances for the quarter ended March 31, 2022 and December 31, 2021 reflect increased promotional equipment sales in our wireless business. We expect the amortization of these promotional costs to increase throughout 2022 and the contract asset to flatten in 2023. Our beginning of period contract liability recorded as customer contract revenue during 2022 was $3,697. Remaining Performance Obligations Remaining performance obligations primarily relate to our Communications segment and represent services we are required to provide to customers under bundled or discounted arrangements, which are satisfied as services are provided over the contract term. In our WarnerMedia segment, the most significant remaining performance obligations relate to the licensing of theatrical and television content which will be made available to customers at some point in the future. In determining the transaction price allocated, we do not include non-recurring charges and estimates for usage, nor do we consider arrangements with an original expected duration of less than one year, which are primarily prepaid wireless and residential internet agreements.

Pension And Postretirement Benefits	NOTE 6. PENSION AND POSTRETIREMENT BENEFITS Many of our employees are covered by one of our noncontributory pension plans. We also provide certain medical, dental, life insurance and death benefits to certain retired employees under various plans and accrue actuarially determined postretirement benefit costs. Our objective in funding these plans, in combination with the standards of the Employee Retirement Income Security Act of 1974, as amended (ERISA), is to accumulate assets sufficient to provide benefits described in the plans to employees upon their retirement. We do not have significant funding requirements in 2022. We recognize actuarial gains and losses on pension and postretirement plan assets in our consolidated results as a component of “Other income (expense) – net” at our annual measurement date of December 31, unless earlier remeasurements are required. We anticipate total distributions from the pension plan will exceed the threshold of service and interest costs for 2022, requiring us to follow settlement accounting and remeasure our pension benefit plan assets and obligations at each quarter-end in 2022, as we expect settlements to occur during each quarter. As part of our first-quarter 2022 remeasurement, the weighted-average discount rate used to measure our pension benefit obligation increased to 3.70% at March 31, 2022, as compared to 3.00% at December 31, 2021. The discount rate in effect for determining pension service and interest costs after remeasurement is 3.80% and 3.40% respectively. The remeasurement reflects an actual return on pension plan assets of (5.20)% (three-month rate) relative to our expected long-term rate of 6.75% (annual rate). Similar to 2022, in 2021 we were required to follow settlement accounting and remeasure our pension benefit plan assets and obligations at each quarter end. The following table details pension and postretirement benefit costs included in the accompanying consolidated statements of income. The service cost component of net periodic pension (credit) cost is recorded in operating expenses in the consolidated statements of income while the remaining components are recorded in “Other income (expense) – net.” Three months ended March 31, 2022 2021 Pension cost: Service cost – benefits earned during the period $ 183 $ 254 Interest cost on projected benefit obligation 320 291 Expected return on assets (868) (877) Amortization of prior service credit (33) (36) Net pension (credit) cost before remeasurement (398) (368) Actuarial (gain) loss (1,012) (2,844) Net pension (credit) cost $ (1,410) $ (3,212) Postretirement cost: Service cost – benefits earned during the period $ 9 $ 11 Interest cost on accumulated postretirement benefit obligation 63 53 Expected return on assets (32) (38) Amortization of prior service credit (582) (634) Net postretirement (credit) cost $ (542) $ (608) Combined net pension and postretirement (credit) cost $ (1,952) $ (3,820) We also provide senior- and middle-management employees with nonqualified, unfunded supplemental retirement and savings plans. For the first quarter ended 2022 and 2021, net supplemental pension benefits costs not included in the table above were $12, respectively. During the first quarter of 2022, we also recorded an actuarial gain of $41.

Fair Value Disclosures [Abstract]
Fair Value Measurements And Disclosure	NOTE 7. FAIR VALUE MEASUREMENTS AND DISCLOSURE The Fair Value Measurement and Disclosure framework in ASC 820, “Fair Value Measurement,” provides a three-tiered fair value hierarchy based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant unobservable inputs. The level of an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Our valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. The valuation methodologies described above may produce a fair value calculation that may not be indicative of future net realizable value or reflective of future fair values. We believe our valuation methods are appropriate and consistent with other market participants. The use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the methodologies used since December 31, 2021. Long-Term Debt and Other Financial Instruments The carrying amounts and estimated fair values of our long-term debt, including current maturities, and other financial instruments, are summarized as follows: March 31, 2022 December 31, 2021 Carrying Fair Carrying Fair Amount Value Amount Value Notes and debentures 1 $ 197,829 $ 209,516 $ 169,147 $ 194,891 Commercial paper 8,069 8,069 6,586 6,586 Investment securities 2 3,201 3,201 3,374 3,374 1 Includes credit agreement borrowings. Excludes note payable to DIRECTV. 2 Excludes investments accounted for under the equity method. The carrying amount of debt with an original maturity of less than one year approximates fair value. The fair value measurements used for notes and debentures are considered Level 2 and are determined using various methods, including quoted prices for identical or similar securities in both active and inactive markets. Following is the fair value leveling for investment securities that are measured at fair value and derivatives as of March 31, 2022 and December 31, 2021. Derivatives designated as hedging instruments are reflected as “Other assets,” “Other noncurrent liabilities,” “Prepaid and other current assets” and “Accounts payable and accrued liabilities” on our consolidated balance sheets. March 31, 2022 Level 1 Level 2 Level 3 Total Equity Securities Domestic equities $ 1,198 $ — $ — $ 1,198 International equities 218 — — 218 Fixed income equities 216 — — 216 Available-for-Sale Debt Securities — 1,285 — 1,285 Asset Derivatives Cross-currency swaps — 162 — 162 Foreign exchange contracts — 2 — 2 Liability Derivatives Cross-currency swaps — (3,680) — (3,680) Foreign exchange contracts — (25) — (25) December 31, 2021 Level 1 Level 2 Level 3 Total Equity Securities Domestic equities $ 1,256 $ — $ — $ 1,256 International equities 227 — — 227 Fixed income equities 230 — — 230 Available-for-Sale Debt Securities — 1,384 — 1,384 Asset Derivatives Cross-currency swaps — 211 — 211 Foreign exchange contracts — 8 — 8 Liability Derivatives Cross-currency swaps — (3,170) — (3,170) Foreign exchange contracts — (41) — (41) Investment Securities Our investment securities include both equity and debt securities that are measured at fair value, as well as equity securities without readily determinable fair values. A substantial portion of the fair values of our investment securities is estimated based on quoted market prices. Investments in equity securities not traded on a national securities exchange are valued at cost, less any impairment, and adjusted for changes resulting from observable, orderly transactions for identical or similar securities. Investments in debt securities not traded on a national securities exchange are valued using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. The components comprising total gains and losses in the period on equity securities are as follows: Three months ended March 31, 2022 2021 Total gains (losses) recognized on equity securities $ (95) $ 55 Gains (Losses) recognized on equity securities sold (7) — Unrealized gains (losses) recognized on equity securities held at end of period $ (88) $ 55 At March 31, 2022, available-for-sale debt securities totaling $1,285 have maturities as follows - less than one year: $61; one to three years: $161; three to five years: $201; five or more years: $862. Our cash equivalents (money market securities), short-term investments (certificate and time deposits) and nonrefundable customer deposits are recorded at amortized cost, and the respective carrying amounts approximate fair values. Short-term investments and nonrefundable customer deposits are recorded in “Prepaid and other current assets” and our investment securities are recorded in “Other Assets” on the consolidated balance sheets. Derivative Financial Instruments We enter into derivative transactions to manage certain market risks, primarily interest rate risk and foreign currency exchange risk. This includes the use of interest rate swaps, interest rate locks, foreign exchange forward contracts and combined interest rate foreign exchange contracts (cross-currency swaps). We do not use derivatives for trading or speculative purposes. We record derivatives on our consolidated balance sheets at fair value that is derived from observable market data, including yield curves and foreign exchange rates (all of our derivatives are Level 2). Cash flows associated with derivative instruments are presented in the same category on the consolidated statements of cash flows as the item being hedged. Fair Value Hedging Periodically, we enter into and designate fixed-to-floating interest rate swaps as fair value hedges. The purpose of these swaps is to manage interest rate risk by managing our mix of fixed-rate and floating-rate debt. These swaps involve the receipt of fixed-rate amounts for floating interest rate payments over the life of the swaps without exchange of the underlying principal amount. We also designate some of our cross-currency swaps as fair value hedges. The purpose of these contracts is to hedge foreign currency risk associated with changes in spot rates on foreign denominated debt. For these hedges we have elected to exclude the change in fair value of the cross-currency swap related to both time value and cross-currency basis spread from the assessment of hedge effectiveness. Unrealized and realized gains or losses from fair value hedges impact the same category on the consolidated statements of income as the item being hedged, including the earnings impact of excluded components. In instances where we have elected to exclude components from the assessment of hedge effectiveness related to fair value hedges, unrealized gains or losses on such excluded components are recorded as a component of accumulated OCI and recognized into earnings through the swap accrual over the life of the hedging instrument. Unrealized gains on derivatives designated as fair value hedges are recorded at fair market value as assets, and unrealized losses are recorded at fair market value as liabilities. Except for excluded components, changes in the fair value of derivative instruments designated as fair value hedges are offset against the change in fair value of the hedged assets or liabilities through earnings. In the three months ended March 31, 2022 and 2021, no ineffectiveness was measured on fair value hedges. Cash Flow Hedging We designate most of our cross-currency swaps as cash flow hedges. We have entered into multiple cross-currency swaps to hedge our exposure to variability in expected future cash flows that are attributable to foreign currency risk generated from our foreign-denominated debt. These agreements include initial and final exchanges of principal from fixed foreign currency denominated amounts to fixed U.S. dollar denominated amounts, to be exchanged at a specified rate that is usually determined by the market spot rate upon issuance. They also include an interest rate swap of a fixed or floating foreign currency-denominated interest rate to a fixed U.S. dollar denominated interest rate. We also designate some of our foreign exchange contracts as cash flow hedges. The purpose of these contracts is to hedge certain forecasted film production costs and film tax incentives denominated in foreign currencies. Unrealized gains on derivatives designated as cash flow hedges are recorded at fair value as assets, and unrealized losses are recorded at fair value as liabilities. For derivative instruments designated as cash flow hedges, changes in fair value are reported as a component of accumulated OCI and are reclassified into the consolidated statements of income in the same period the hedged transaction affects earnings. Periodically, we enter into and designate interest rate locks to partially hedge the risk of changes in interest payments attributable to increases in the benchmark interest rate during the period leading up to the probable issuance of fixed-rate debt. We designate our interest rate locks as cash flow hedges. Gains and losses when we settle our interest rate locks are amortized into income over the life of the related debt. Over the next 12 months, we expect to reclassify $70 from accumulated OCI to “Interest expense” due to the amortization of net losses on historical interest rate locks. Net Investment Hedging We have designated €1,450 million aggregate principal amount of debt as a hedge of the variability of some of the Euro-denominated net investments of our subsidiaries. The gain or loss on the debt that is designated as, and is effective as, an economic hedge of the net investment in a foreign operation is recorded as a currency translation adjustment within accumulated OCI, net on the consolidated balance sheets. Net gains on net investment hedges recognized in accumulated OCI in the first quarter of 2022 were $44. Collateral and Credit-Risk Contingency We have entered into agreements with our derivative counterparties establishing collateral thresholds based on respective credit ratings and netting agreements. At March 31, 2022, we had posted collateral of $606 (a deposit asset) and held collateral of $23 (a receipt liability). Under the agreements, if AT&T’s credit rating had been downgraded two ratings levels by Fitch Ratings, one level by S&P and one level by Moody’s before the final collateral exchange in March, we would have been required to post additional collateral of $62. If AT&T’s credit rating had been downgraded three ratings levels by Fitch Ratings, two levels by S&P, and two levels by Moody’s, we would have been required to post additional collateral of $3,373. At December 31, 2021, we had posted collateral of $135 (a deposit asset) and held collateral of $7 (a receipt liability). We do not offset the fair value of collateral, whether the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) exists, against the fair value of the derivative instruments. Following are the notional amounts of our outstanding derivative positions: March 31, December 31, 2022 2021 Cross-currency swaps $ 40,737 $ 40,737 Foreign exchange contracts 213 30 Total $ 40,950 $ 40,767 Following are the related hedged items affecting our financial position and performance: Effect of Derivatives on the Consolidated Statements of Income Three months ended March 31, Fair Value Hedging Relationships 2022 2021 Interest rate swaps (Interest expense): Gain (Loss) on interest rate swaps $ (1) $ (1) Gain (Loss) on long-term debt 1 1 Cross-currency swaps: Gain (Loss) on cross-currency swaps (37) (48) Gain (Loss) on long-term debt 37 48 Gain (Loss) recognized in accumulated OCI 9 (1) In addition, the net swap settlements that accrued and settled in the periods above were offset against “Interest expense.” The following table presents information for our cash flow hedging relationships: Three months ended March 31, Cash Flow Hedging Relationships 2022 2021 Cross-currency swaps: Gain (Loss) recognized in accumulated OCI $ 315 $ 644 Foreign exchange contracts: Gain (Loss) recognized in accumulated OCI 3 4 Other income (expense) - net reclassified from accumulated OCI into income 1 (5) Interest rate locks: Gain (Loss) recognized in accumulated OCI — — Interest income (expense) reclassified from accumulated OCI into income (20) (25)

Business Combination and Asset Acquisition [Abstract]
Acquisitions, Dispositions And Other Adjustments	NOTE 8. ACQUISITIONS, DISPOSITIONS AND OTHER ADJUSTMENTS Acquisitions Spectrum Auction On January 14, 2022, the Federal Communications Commission (FCC) announced that we were the winning bidder for 1,624 3.45 GHz licenses in Auction 110. We provided the FCC with an upfront deposit of $123 in the third quarter of 2021 and paid the remaining $8,956 in the first quarter of 2022, for a total of $9,079. We funded the purchase price using cash and short-term investments. The amounts deposited toward the acquisition of the licenses and capitalized interest were reported as “Deposits on Wireless Licenses” on our consolidated balance sheet as of March 31, 2022. We expect to receive the licenses in the second quarter of 2022. In February 2021, the FCC announced that we were the winning bidder for 1,621 C-Band licenses. We provided the FCC an upfront deposit of $550 in 2020 and cash payments totaling $22,856 in the first quarter of 2021, for a total of $23,406 as of March 31, 2022. The licenses were received in July 2021. Cash paid, including spectrum deposits (net of refunds), capitalized interest, and any payments for incentive and relocation costs are included in “Acquisitions, net of cash acquired” on our consolidated statements of cash flows. Interest is capitalized until the spectrum is ready for its intended use. Pending Dispositions WarnerMedia On May 17, 2021, we entered into an agreement to combine our WarnerMedia segment, except for certain retained assets such as Xandr, with a subsidiary of Discovery in a Reverse Morris Trust transaction. On April 8, 2022, we completed the separation and distribution of our WarnerMedia business, and merger of Spinco, an AT&T subsidiary formed to hold the WarnerMedia business, with a subsidiary of Discovery, Inc., which was renamed Warner Bros. Discovery, Inc. Each AT&T shareholder was entitled to receive 0.241917 shares of WBD common stock for each share of AT&T common stock held as of the record date, which represented approximately 71% of WBD. In connection with and in accordance with the terms of the transaction, prior to the distribution and merger, AT&T received approximately $40,400, which includes $38,800 of cash and $1,600 of debt retained by WarnerMedia. At March 31, 2022, the WarnerMedia business did not meet the criteria for held-for-sale and, accordingly, its financial results are included in continuing operations for all periods presented herein. In preparation for the close of the WarnerMedia/Discovery transaction, in March 2022, Spinco issued $30,000 of Spinco senior notes with a weighted-average interest rate of 4.5% and maturities ranging from 2024 to 2062. These notes conveyed to WBD upon close of the transaction. Our cash balance at March 31, 2022, includes the proceeds of this issuance that were retained by AT&T in connection with the close of the transaction. In connection with the debt issuances, the aggregate commitment amount under the existing Spinco commitment letter (Bridge Loan) was reduced from $31,500 to $1,687, with no amounts outstanding as of March 31, 2022. See Note 13 for additional information on the WarnerMedia/Discovery transaction. Xandr On December 21, 2021, we entered into an agreement to sell the marketplace component of Xandr, primarily representing the AppNexus business, to Microsoft, which is expected to close in 2022, subject to customary regulatory approvals. This advertising business is included in our WarnerMedia segment and is excluded from the WarnerMedia/Discovery transaction. We applied held-for-sale accounting treatment to the related assets and liabilities of this business at December 31, 2021 and March 31, 2022, resulting in approximately $550 of goodwill and other intangible assets and $405 of accounts receivable being reclassified to “Prepaid and other current assets” as of March 31, 2022. Beginning with the second quarter of 2022, Xandr will be reflected in our financial statements as discontinued operations.

Receivables [Abstract]
Sales Of Receivables	NOTE 9. SALES OF RECEIVABLES We have agreements with various third-party financial institutions pertaining to the sales of certain types of our accounts receivable. The most significant of these programs are discussed in detail below and generally consist of (1) receivables arising from equipment installment plans, which are sold for cash and a deferred purchase price, and (2) revolving service and trade receivables, which convey to WBD following the WarnerMedia/Discovery transaction. Under these programs, we transfer receivables to purchasers in exchange for cash and additional consideration upon settlement of the receivables, where applicable. Under the terms of our agreements for these programs, we continue to bill and collect the payments from our customers on behalf of the financial institutions. The sales of receivables did not have a material impact on our consolidated statements of income or to “Total Assets” reported on our consolidated balance sheets. We reflect cash receipts on sold receivables as cash flows from operations in our consolidated statements of cash flows. Cash receipts on the deferred purchase price are classified as cash flows from investing activities. Our equipment installment and revolving receivable programs are discussed in detail below. The following table sets forth a summary of the receivables and accounts being serviced: March 31, 2022 December 31, 2021 Equipment Equipment Installment Revolving Installment Revolving Gross receivables: $ 3,616 $ 3,359 $ 4,361 $ 3,527 Balance sheet classification Accounts receivable Notes receivable 1,689 — 1,846 — Trade receivables 465 3,157 606 3,337 Other Assets Noncurrent notes and trade receivables 1,462 202 1,909 190 Outstanding portfolio of receivables derecognized from our consolidated balance sheets 10,645 6,172 9,767 6,280 Cash proceeds received, net of remittances 1 7,670 6,172 6,644 6,280 1 Represents amounts to which financial institutions remain entitled, excluding the deferred purchase price. Equipment Installment Receivables Program We offer our customers the option to purchase certain wireless devices in installments over a specified period of time and, in many cases, once certain conditions are met, they may be eligible to trade in the original equipment for a new device and have the remaining unpaid balance paid or settled. We maintain a program under which we transfer a portion of these receivables through our bankruptcy-remote subsidiary in exchange for cash and additional consideration upon settlement of the receivables, referred to as the deferred purchase price. In the event a customer trades in a device prior to the end of the installment contract period, we agree to make a payment to the financial institutions equal to any outstanding remaining installment receivable balance. Accordingly, we record a guarantee obligation for this estimated amount at the time the receivables are transferred. The following table sets forth a summary of equipment installment receivables sold under this program during the three months ended March 31, 2022 and 2021: Three months ended March 31, 2022 2021 Gross receivables sold $ 3,601 $ 3,935 Net receivables sold 1 3,478 3,826 Cash proceeds received 3,316 3,519 Deferred purchase price recorded 245 414 Guarantee obligation recorded 152 146 1 Receivables net of allowance, imputed interest and equipment trade-in right guarantees. The deferred purchase price and guarantee obligation are initially recorded at estimated fair value and subsequently adjusted for changes in present value of expected cash flows. The estimation of their fair values is based on remaining installment payments expected to be collected and the expected timing and value of device trade-ins. The estimated value of the device trade-ins considers prices offered to us by independent third parties and contemplate changes in value after the launch of a device model. The fair value measurements used for the deferred purchase price and the guarantee obligation are considered Level 3 under the Fair Value Measurement and Disclosure framework (see Note 7). The following table presents the previously transferred equipment installment receivables, which we repurchased in exchange for the associated deferred purchase price during the three months ended March 31, 2022 and 2021: Three months ended March 31, 2022 2021 Fair value of repurchased receivables $ 905 $ 273 Carrying value of deferred purchase price 902 253 Gain on repurchases 1 $ 3 $ 20 1 These gains are included in “Selling, general and administrative” in the consolidated statements of income. At March 31, 2022 and December 31, 2021, our deferred purchase price receivable was $3,066 and $3,177, respectively, of which $1,984 and $2,123 are included in “Prepaid and other current assets” on our consolidated balance sheets, with the remainder in “Other Assets.” The guarantee obligation at March 31, 2022 and December 31, 2021 was $432 and $371, respectively, of which $140 and $101 are included in “Accounts payable and accrued liabilities” on our consolidated balance sheets, with the remainder in “Other noncurrent liabilities.” Our maximum exposure to loss as a result of selling these equipment installment receivables is limited to the total amount of our deferred purchase price and guarantee obligation. Revolving Receivables Program We have a revolving agreement to transfer up to $6,680 of certain receivables through our bankruptcy-remote subsidiaries to various financial institutions on a recurring basis in exchange for cash equal to the gross receivables transferred. This agreement is subject to renewal on an annual basis and the transfer limit may be expanded or reduced from time to time. As customers pay their balances, we transfer additional receivables into the program, resulting in our gross receivables sold exceeding net cash flow impacts (e.g., collect and reinvest). The transferred receivables are fully guaranteed by our bankruptcy-remote subsidiaries, which hold additional receivables in the amount of $3,359 that are pledged as collateral under this agreement. The transfers are recorded at fair value of the proceeds received and obligations assumed less derecognized receivables. The obligation is subsequently adjusted for changes in estimated expected credit losses and interest rates. Our maximum exposure to loss related to these receivables transferred is limited to the amount outstanding. The revolving credit agreement conveyed to WBD upon close of the WarnerMedia/Discovery transaction. The fair value measurement used for the obligation is considered Level 3 under the Fair Value Measurement and Disclosure framework (see Note 7). The following table sets forth a summary of receivables sold: Three months ended March 31, 2022 2021 Gross receivables sold/cash proceeds received 1 $ 4,178 $ 5,204 Total collections under revolving agreement 2 3,856 4,749 Receivables repurchased 430 — Net cash proceeds (paid) received $ (108) $ 455 Net receivables sold 3 $ 3,728 $ 5,125 Obligations recorded 66 142 1 Includes initial sales of receivables of $0 and $700 for the three months ended March 31, 2022 and 2021, respectively. 2 Includes collections of $108 and $245 for the three months ended March 31, 2022 and 2021, respectively, that were not reinvested under the revolving agreement. 3 Receivables net of allowance, return and incentive reserves and imputed interest.

Leases [Abstract]
Leases	NOTE 10. LEASES We have operating and finance leases for certain facilities and equipment used in operations. Our leases generally have remaining lease terms of up to 15 years. Some of our real estate operating leases contain renewal options that may be exercised, and some of our leases include options to terminate the leases within one year. We have recognized a right-of-use asset for both operating and finance leases, and an operating lease liability that represents the present value of our obligation to make payments over the lease term. The present value of the lease payments is calculated using the incremental borrowing rate for operating and finance leases, which was determined using a portfolio approach based on the rate of interest that we would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. We use the unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate in the currency of the lease, which will be updated on a quarterly basis for measurement of new lease liabilities.

The components of lease expense were as follows: Three months ended March 31, 2022 2021 Operating lease cost $ 1,448 $ 1,458 Finance lease cost: Amortization of right-of-use assets $ 47 $ 69 Interest on lease obligation 38 39 Total finance lease cost $ 85 $ 108 The following table provides supplemental cash flows information related to leases: Three months ended March 31, 2022 2021 Cash Flows from Operating Activities Cash paid for amounts included in lease obligations: Operating cash flows for operating leases $ 1,289 $ 1,254 Supplemental Lease Cash Flow Disclosures Operating lease right-of-use assets obtained in exchange for new 897 1,050 The following tables set forth supplemental balance sheet information related to leases: March 31, December 31, Operating Leases Operating lease right-of-use assets $ 23,941 $ 24,180 Accounts payable and accrued liabilities $ 3,694 $ 3,706 Operating lease obligation 20,917 21,261 Total operating lease obligation $ 24,611 $ 24,967 Finance Leases Property, plant and equipment, at cost $ 2,666 $ 2,609 Accumulated depreciation and amortization (1,158) (1,120) Property, plant and equipment, net $ 1,508 $ 1,489 Current portion of long-term debt $ 148 $ 137 Long-term debt 1,509 1,484 Total finance lease obligation $ 1,657 $ 1,621 March 31, 2022 2021 Weighted-Average Remaining Lease Term (years) Operating leases 8.2 8.4 Finance leases 8.0 9.8 Weighted-Average Discount Rate Operating leases 3.7 % 4.0 % Finance leases 7.8 % 8.0 % The following table provides the expected future minimum maturities of lease obligations: At March 31, 2022 Operating Finance Leases Leases Remainder of 2022 $ 3,703 $ 232 2023 4,584 295 2024 4,059 268 2025 3,317 256 2026 2,628 254 Thereafter 11,121 1,060 Total lease payments 29,412 2,365 Less: imputed interest (4,801) (708) Total $ 24,611 $ 1,657

Transactions with DIRECTV

Related Party Transactions [Abstract]
Related Party Transactions Disclosure	NOTE 11. TRANSACTIONS WITH DIRECTV On July 31, 2021, we closed our transaction with TPG to form a new company named DIRECTV. The transaction resulted in our deconsolidation of the Video business. As DIRECTV is jointly governed by a board with representation from both AT&T and TPG, with TPG having tie-breaking authority on certain key decisions, most significantly the appointment and removal of the CEO, we have concluded that we are not the primary beneficiary of DIRECTV. Effective August 1, 2021, we began accounting for our investment in DIRECTV under the equity method and recorded our share of DIRECTV earnings as equity in net income of affiliates, with DIRECTV considered a related party. For the three months ended March 31, 2022, our share of DIRECTV’s earnings included in equity in net income of affiliates was $522. Cash distributions from DIRECTV in the first quarter totaled $1,837, with $522 classified as operating activities and $1,315 classified as investing activities in our consolidated statement of cash flows. Our investment in DIRECTV at March 31, 2022 was $4,228. In addition to the assets and liabilities contributed to DIRECTV, at close we recorded total obligations of $2,100 to cover certain net losses under the NFL SUNDAY TICKET contract, of which $1,800 is in the form of a note payable to DIRECTV. During the first quarter of 2022, cash payments to DIRECTV on the note totaled $294 and were classified as financing activities in our consolidated statement of cash flows. Amounts due under the DIRECTV note were $1,047 at March 31, 2022. WarnerMedia licenses content and programming and provides advertising services to DIRECTV. Revenue recognized from DIRECTV, which was previously eliminated prior to the transaction with TPG, totaled approximately $400 for the three months ended March 31, 2022 . Pursuant to a commercial agreement, WarnerMedia continues to sell DIRECTV’s advertising inventory under a revenue sharing agreement. WarnerMedia records amounts billed as advertising revenue and recognizes expense for DIRECTV’s revenue share, which was approximately $280 for the three months ended March 31, 2022 . These transactions are no longer related party transactions for AT&T following the close of the WarnerMedia/Discovery transaction (see Note 13). We also provide DIRECTV with network transport for U-verse products and sales services under commercial arrangements for up to five years. Under separate transition services agreements, we provide DIRECTV certain operational support, including servicing of certain of their customer receivables for up to three years. For the three months ended March 31, 2022, we billed DIRECTV approximately $300 for these costs, which were recorded as a reduction to the operations and support expenses incurred and resulted in net retained costs to AT&T of approximately $128 in the first quarter. At March 31, 2022 , we had accounts receivable from DIRECTV of $478 and accounts payable to DIRECTV of $335. We are not committed, implicitly or explicitly to provide financial or other support, other than noted above, as our involvement with DIRECTV is limited to the carrying amount of the assets and liabilities recognized on our balance sheet.

Subsequent Events [Abstract]
Subsequent Events (Unaudited)	NOTE 13. SUBSEQUENT EVENTS On April 8, 2022, we completed the separation of the WarnerMedia business in a Reverse Morris Trust transaction, under which the WarnerMedia business was distributed to AT&T stockholders via a pro rata dividend, followed by the combination with a subsidiary of Discovery. In connection with and in accordance with the terms of the transaction, prior to the distribution and merger, AT&T received approximately $40,400, which includes $38,800 of cash and $1,600 of debt retained by WarnerMedia. The cash portion is subject to potential post close adjustments for certain items. The WarnerMedia business, including amortization of intangible assets and other transactions costs, represents approximately 23% of AT&T operating revenues and 2% of AT&T operating income for the three months ended March 31, 2022. Beginning with our second quarterly report on Form 10-Q for the period ended June 30, 2022, the WarnerMedia business will be reflected in our historical financial statements as discontinued operations, including for periods up to the consummation of the WarnerMedia/Discovery transaction. For discontinued operations, we evaluated transactions completed during 2021 that were components of AT&T’s single plan of a strategic shift, including dispositions that may not have individually met the criteria due to materiality, and have determined discontinued operations to be comprised of WarnerMedia, Vrio, Xandr and Playdemic. These businesses will be reflected in our historical financial statements as discontinued operations, including for periods prior to the consummation of the WarnerMedia/Discovery transaction. Financing Activities Related to Spinco In preparation for close, on April 7, 2022, Spinco drew $10,000 on the Spinco Term Loan, which conveyed to WBD. Total debt conveyed was approximately $41,600, which includes $1,600 of existing WarnerMedia debt, $30,000 of Spinco senior notes issued in March 2022 and the $10,000 Spinco Term Loan. Financing Activities Impacting Continuing Operations On March 31, 2022, we issued a notice for the redemption in full of all of the outstanding $1,962 aggregate principal amount of 3.000% Global Notes due June 30, 2022. We redeemed the notes on April 30, 2022 at 100% of the principal amount. On April 11, 2022, we made an optional repayment of the full $750 outstanding pursuant to a private financing arrangement. On April 11, 2022, we also issued a notice for the redemption in full of all of outstanding approximately $9,042 aggregate principal amount of various global notes due 2022 to 2026 with coupon rates ranging from 2.625% to 4.450% (Make-Whole Notes). The Make-Whole Notes will be redeemed on the redemption dates set forth in the notices of redemption, at “make whole” redemption prices to be calculated as set forth in the respective redemption notices. On April 13, 2022, we paid off $7,350 outstanding under the 2021 Syndicated Term Loan and $2,000 outstanding under the BAML Bilateral Term Loan and terminated the facilities.

Preparation Of Interim Financ_2

Preparation Of Interim Financial Statements (Policies)	3 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Principles of Consolidation [Policy Text Block]	All significant intercompany transactions are eliminated in the consolidation process. Investments in subsidiaries and partnerships which we do not control but have significant influence are accounted for under the equity method. Earnings from certain investments accounted for using the equity method are included in our results on a one quarter lag. We also record our proportionate share of our equity method investees’ other comprehensive income (OCI) items, including translation adjustments.
Basis of Accounting [Policy Text Block]	The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including estimates of probable losses and expenses, that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain prior period amounts have been conformed to the current period’s presentation (see Note 4).
Customer Acquisition and Fulfillment Costs [Policy Text Block]	Customer Acquisition and Fulfillment Costs During the first quarter of 2022, we updated our analysis of expected economic lives of customer relationships. As of January 1, 2022, we extended the amortization period for deferred acquisition and fulfillment contract costs within Mobility and broadband/fiber in Consumer Wireline and Business Wireline to better reflect the estimated economic lives of the relationships. These changes in accounting estimate decreased other cost of revenues approximately $135, or $0.01 per diluted share, in the first quarter of 2022.
Fiber Network Assets, Policy [Policy Text Block]	Fiber Network Assets During the first quarter of 2022, we updated our analysis of economic lives of AT&T owned fiber network assets. As of January 1, 2022, we extended the estimated economic life and depreciation period of such costs to better reflect the physical life of the assets that we had been experiencing and absence of technological changes that would replace fiber as the best broadband technology in the industry. The change in accounting estimate decreased depreciation expense $70, or $0.01 per diluted share, in the first quarter of 2022.
Convertible Instruments, Policy [Policy Text Block]	Convertible Instruments As of January 1, 2022, we adopted, through retrospective application, Accounting Standards Update (ASU) No. 2020-06, “Debt—Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (ASU 2020-06). ASU 2020-06 requires that instruments which may be settled in cash or stock are presumed settled in stock in calculating diluted earnings per share. While our intent is to settle the Mobility II preferred interests in cash, the ability to settle this instrument in AT&T shares will result in additional dilutive impact, the magnitude of which is influenced by the fair value of the Mobility II preferred interests and the average AT&T common stock price during the reporting period, which could vary from period-to-period.
New Accounting Pronouncement, Policy [Policy Text Block]	Government Assistance The Financial Accounting Standards Board (FASB) issued ASU No, 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance” (ASU 2021-10), which requires annual disclosures, beginning with the 2022 Annual Report on Form 10-K, in the notes to the financial statements, about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy to other guidance. The annual disclosures include terms and conditions, accounting treatment and impacted financial statement lines reflecting the impact of the transactions. ASU 2021-10 will be effective for annual reporting periods beginning after December 15, 2021, which we plan to adopt under prospective application for all in scope government transactions in the financial statements as of our adoption date or thereafter.
Recognition of Actuarial Gains and Losses [Policy Text Block]	We recognize actuarial gains and losses on pension and postretirement plan assets in our consolidated results as a component of “Other income (expense) – net” at our annual measurement date of December 31, unless earlier remeasurements are required. We anticipate t
Derivatives, Offsetting Fair Value Amounts [Policy Text Block]	We do not offset the fair value of collateral, whether the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) exists, against the fair value of the derivative instruments.
