Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements are unaudited and were prepared in accordance with the instructions for Form 10‑Q and Article 10 of Regulation S-X. In compliance with those instructions, certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") have been condensed or omitted. The unaudited condensed consolidated financial statements in this quarterly report are presented on a consolidated basis and include the accounts of the Company and its majority-owned subsidiaries. Results of operations and cash flows for the interim periods are not necessarily indicative of the results that may be expected for the entire year. All significant intercompany transactions and accounts have been eliminated as of September 30, 2022 and December 31, 2021 and for all periods presented. In the opinion of management, these condensed consolidated financial statements include all the normal recurring adjustments necessary to fairly present the Company’s condensed consolidated results of operations, financial position, and cash flows as of September 30, 2022 and for all periods presented. These condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements within the Company’s Annual Report on Form 10‑K for the year ended December 31, 2021. Consistent with industry practice, the accompanying Condensed Consolidated Balance Sheets are unclassified due to the short-term nature of the Company’s settlement obligations contrasted with the Company’s ability to invest cash awaiting settlement in long-term investment securities.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.
Revenue Recognition	The Company’s revenues are primarily derived from consideration paid by customers to transfer money. These revenues vary by transaction based upon factors such as channel, send and receive locations, the principal amount sent, whether the money transfer involves different send and receive currencies, the difference between the exchange rate set by the Company to the customer and the rate available in the wholesale foreign exchange market, and speed of service, as applicable. The Company also offers several other services, including foreign exchange and payment services and other bill payment services, for which revenue is impacted by similar factors. For the substantial majority of the Company’s revenues, the Company acts as the principal in transactions and reports revenue on a gross basis, as the Company controls the service at all times prior to transfer to the customer, is primarily responsible for fulfilling the customer contracts, has the risk of loss, and has the ability to establish transaction prices. The Company also provides services to financial institutions and other third parties to enable such entities to offer money transfer services to their own customers under their brands. Generally, in these arrangements, consumers agree to terms and conditions specified by the financial institution or other third party that, among other things, establish pricing paid by the consumer for the service. The Company recognizes revenue on a net basis under these arrangements. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities.
Earnings Per Share	The calculation of basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Outstanding options to purchase Western Union stock and unvested shares of restricted stock are excluded from basic shares outstanding. Diluted earnings per share reflects the potential dilution that could occur if outstanding stock options at the presented dates are exercised and shares of restricted stock have vested, using the treasury stock method. The treasury stock method assumes proceeds from the exercise price of stock options and the unamortized compensation expense of options and restricted stock are available to acquire shares at an average market price throughout the period, and therefore, reduce the dilutive effect.
Investment Securities	Investment securities included in Settlement assets in the Company’s Condensed Consolidated Balance Sheets consist primarily of highly-rated state and municipal debt securities, including fixed-rate term notes and variable-rate demand notes. Variable-rate demand note securities can be put (sold at par) typically on a daily basis with settlement periods ranging from the same day to one week but have varying maturities through 2061. These securities may be used by the Company for short-term liquidity needs and held for short periods of time. Investment securities are exposed to market risk due to changes in interest rates and credit risk. The Company is required to hold highly-rated, investment grade securities and such investments are restricted to satisfy outstanding settlement obligations in accordance with applicable regulatory requirements. The Company’s investment securities are classified as available-for-sale and recorded at fair value. Western Union regularly monitors credit risk and attempts to mitigate its exposure by investing in highly-rated securities and through investment diversification. Unrealized gains on available-for-sale securities are excluded from earnings and presented as a component of accumulated other comprehensive loss, net of related deferred taxes. Available-for-sale securities with a fair value below the amortized cost basis are evaluated on an individual basis to determine whether the impairment is due to credit-related factors or noncredit-related factors. Factors that could indicate a credit loss exists include but are not limited to: (i) negative earnings performance, (ii) credit rating downgrades, or (iii) adverse changes in the regulatory or economic environment of the asset. Any impairment that is not credit-related is excluded from earnings and presented as a component of accumulated other comprehensive loss, net of related deferred taxes, unless the Company intends to sell the impaired security, or it is more likely than not that the Company will be required to sell the security before recovering its amortized cost basis. Credit-related impairments are recognized immediately as an adjustment to earnings, regardless of whether the Company has the ability or intent to hold the security to maturity and are limited to the difference between fair value and the amortized cost basis. As of September 30, 2022, the Company had the intent to sell certain state and municipal debt securities and recognized an impairment of $4.6 million, which was recorded to Revenues in the Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2022. The sale of these securities was completed in the first week of October. The Company does not intend to sell the remaining securities and does not expect it will be required to sell the remaining securities prior to recovering their amortized cost basis. The Company’s provision for credit losses on its available-for-sale securities during the three and nine months ended September 30, 2022 and 2021 and the related allowance for credit losses as of September 30, 2022 and December 31, 2021 were immaterial.
Foreign Currency - Derivatives	Foreign Currency Derivatives The Company’s policy is to use longer duration foreign currency forward contracts, with maturities of up to 36 months at inception and a targeted weighted-average maturity of approximately one year, to help mitigate some of the risk that changes in foreign currency exchange rates compared to the United States dollar could have on forecasted revenues denominated in other currencies related to its business. As of September 30, 2022, these foreign currency forward contracts had maturities of a maximum of 24 months with a weighted-average maturity of approximately one year. These contracts are accounted for as cash flow hedges of forecasted revenue, with effectiveness assessed based on changes in the spot rate of the affected currencies during the period of designation and thus time value is excluded from the assessment of effectiveness. The initial value of the excluded components is amortized into Revenues within the Company’s Condensed Consolidated Statements of Income. The Company also uses short duration foreign currency forward contracts, generally with maturities ranging from a few days to one month, to offset foreign exchange rate fluctuations on settlement assets and obligations between initiation and settlement. In addition, forward contracts, typically with maturities of less than one year at inception, are utilized to offset foreign exchange rate fluctuations on certain foreign currency denominated cash and other asset and liability positions. None of these contracts are designated as accounting hedges.
Foreign Currency - Business Solutions	Business Solutions Operations The Company writes derivatives, primarily foreign currency forward contracts and option contracts, mostly with small and medium size enterprises and derives a currency spread from this activity as part of its Business Solutions operations. On August 4, 2021, the Company entered into an agreement to sell its Business Solutions business to Goldfinch Partners LLC and The Baupost Group LLC. During the third quarter of 2022, all parties agreed for the sale to be completed in three closings instead of two. The first closing occurred on March 1, 2022, the second is expected to occur in December 2022, and the third is expected in the first quarter of 2023. See Note 4 for further information regarding this transaction. The Company aggregates its Business Solutions foreign currency exposures arising from customer contracts, including the derivative contracts described above, and hedges the resulting net currency risks by entering into offsetting contracts with Convera through the end of the third closing of the Business Solutions divestiture. The derivatives written are part of the broader portfolio of foreign currency positions arising from the Company’s cross-currency payments operations, which primarily include spot exchanges of currency in addition to forwards and options. Foreign exchange revenues from the total portfolio of positions included in Revenues in the Company’s Condensed Consolidated Statements of Income were $39.3 million and $99.5 million for the three months ended September 30, 2022 and 2021, respectively, and $151.5 million and $271.4 million for the nine months ended September 30, 2022 and 2021, respectively. None of the derivative contracts used in Business Solutions operations are designated as accounting hedges and the majority of these derivative contracts have a duration at inception of less than one year.
Interest Rate Hedging	Interest Rate Hedging Periodically, the Company utilizes interest rate swaps to effectively change the interest rate payments on a portion of its notes from fixed-rate payments to short-term, variable-rate payments in order to manage its overall exposure to interest rate fluctuations. The Company designates these derivatives as fair value hedges. The change in the fair value of the interest rate swaps is offset by a change in the carrying value of the debt being hedged within Borrowings in the Condensed Consolidated Balance Sheets. Interest expense in the Condensed Consolidated Statements of Income has been adjusted to include the effects of interest accrued on the swaps.
