Accounting Policies [Abstract]
Significant Accounting and Reporting Policies	Significant Accounting and Reporting Policies Basis of Presentation Any reference in this report to “the Company,” “we,” “our,” “us,” and “its’” are to TransUnion and its consolidated subsidiaries, collectively. The accompanying unaudited consolidated financial statements of TransUnion and subsidiaries 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, 2017 . 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, 2016 , filed with the Securities and Exchange Commission (“SEC”) on February 15, 2017. Principles of Consolidation The consolidated financial statements of TransUnion include the accounts of TransUnion and all of its controlled subsidiaries. Investments in unconsolidated entities in which the Company is able to exercise significant influence are accounted for using the equity method. Nonmarketable investments in unconsolidated entities in which the Company 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 consolidated financial statements. Recently Adopted Accounting Pronouncements On March 30, 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU simplifies several aspects of the accounting for share-based payment award transactions, including income tax consequences, classification of awards, and classification on the statement of cash flows. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods therein. The provisions in the new guidance related to income taxes that impacted us were adopted prospectively. As a result of this guidance, beginning January 1, 2017, we record excess tax benefits as a reduction to income tax expense and reflect excess tax benefits as operating cash flows. Depending on the exercise pattern of our remaining outstanding options, and the value of our stock on the exercise dates of our stock options and vest dates of our restricted stock units relative to the corresponding fair value of those awards on their grant dates, there could be a material impact on our future income tax expense. Recent Accounting Pronouncements Not Yet Adopted On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) . During 2016, the FASB issued several additional ASU's related to revenue recognition. This series of comprehensive guidance will replace all existing revenue recognition guidance and is effective for annual reporting periods beginning after December 15, 2017, and interim periods therein. We will adopt this standard beginning January 1, 2018, and will use the modified retrospective approach, with the cumulative effect recognized in the opening balance of retained earnings. We have categorized our various contract revenue streams in alignment with the new standard. We are in the process of finalizing our review of contracts and have applied the five-step model specified by the new guidance. The five-step model includes: (1) determination of whether a contract, an agreement between two or more parties that creates legally enforceable rights and obligations, exists; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when (or as) the performance obligation is satisfied. Additionally, we are in the process of assessing the impact of the new standard on our disclosures and internal controls. We continue to evaluate the impact this guidance will have on our consolidated financial statements and disclosures and prepare for the adoption of the standard on January 1, 2018, including readying our internal processes and control environment for new requirements, particularly around enhanced disclosures. At this point, we have not identified anything that we believe will have a material impact on how we record revenue, but our conclusions will continue to evolve as we finalize our contract reviews and evaluation. The FASB has issued, and may issue in the future, interpretative guidance, which may impact our evaluation. We believe that we are following an appropriate timeline to allow for proper revenue recognition, presentation and disclosures upon adoption of this new standard on January 1, 2018. On January 5, 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU is intended to improve the recognition and measurement of financial instruments. Among other things, the ASU requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. This guidance is effective for fiscal years beginning after December 15, 2017, and interim periods therein. We are currently assessing the impact this guidance will have on our consolidated financial statements. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . This ASU, among other things, will require lessees to record a lease liability, which is an obligation to make lease payments arising from a lease, and right-of-use asset, which is an asset that represents the right to use, or control the use of, a specified asset for the lease term, for all long-term leases. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently assessing the impact this guidance will have on our consolidated financial statements. On June 16, 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. In addition, these amendments require the measurement of all expected credit losses for financial assets, including trade accounts receivable, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This guidance is effective for annual reporting periods beginning after December 15, 2019, including interim period therein. We are currently assessing the impact this guidance will have on our consolidated financial statements. On August 26, 2016 the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods therein. We are currently assessing the impact this guidance will have on our consolidated statements of cash flows. On August 28, 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new standard is intended to improve and simplify accounting rules around hedge accounting. The guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods therein. We are currently assessing the impact this guidance will have on our consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The following table summarizes financial instruments measured at fair value, on a recurring basis, as of September 30, 2017 : (in millions) Total Level 1 Level 2 Level 3 Assets Trading securities $ 12.6 $ 9.6 $ 3.0 $ — Available-for-sale securities 3.2 — 3.2 — Total $ 15.8 $ 9.6 $ 6.2 $ — Liabilities Contingent consideration $ (1.7 ) $ — $ — $ (1.7 ) Interest rate caps (0.7 ) — (0.7 ) — Total $ (2.4 ) $ — $ (0.7 ) $ (1.7 ) Level 1 instruments consist of exchange-traded mutual funds. Exchange-traded mutual funds are trading securities valued at their current market prices. These securities relate to the nonqualified deferred compensation plan held in trust for the benefit of plan participants. Level 2 instruments consist of pooled separate accounts, foreign exchange-traded corporate bonds and interest rate caps. Pooled separate accounts are designated as trading securities valued at net asset values. These securities relate to the nonqualified deferred compensation plan held in trust for the benefit of plan participants. Foreign exchange-traded corporate bonds are available-for-sale securities valued at their current quoted prices. These securities mature between 2027 and 2033. The interest rate caps fair values are determined by discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the caps in conjunction with the cash payments related to financing the premium of the interest rate caps. The variable interest rates used in the calculation of projected receipts on the caps are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. See Note 8, “Debt,” for additional information regarding interest rate caps. Unrealized gains and losses on trading securities are included in net income, while unrealized gains and losses on available-for-sale securities are included in other comprehensive income. There were no significant realized or unrealized gains or losses on our securities for any of the periods presented. Level 3 instruments consist of contingent obligations related to companies we have acquired with remaining maximum payouts totaling $15.7 million . These obligations are contingent upon meeting certain quantitative or qualitative performance metrics through 2018 and are included in other current liabilities and other liabilities on our balance sheet. The fair values of the obligations are determined based on an income approach, using management’s expectations including future expected earnings of the acquired entities. We assess the fair value of these obligations each reporting period with any changes reflected as gains or losses in selling, general and administrative expenses in the consolidated statements of income. During the three and nine months ended September 30, 2017 , we recorded expenses of $0.4 million and $0.2 million , respectively, as a result of changes to the fair value of these obligations.

Investments in Affiliated Companies [Abstract]
Equity Method Investments and Joint Ventures Disclosure	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. We use the equity method to account for investments in affiliates 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 nonmarketable investments in affiliates where we are not able to exercise significant influence. 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 has occurred. There were no other-than-temporary impairments of investments in affiliated companies during the three and nine months ended September 30, 2017 or 2016 . Investments in affiliated companies consisted of the following: (in millions) September 30, December 31, 2016 Total equity method investments $ 49.6 $ 39.4 Total cost method investments 26.2 23.2 Total investments in affiliated companies $ 75.8 $ 62.6 These balances are included in other assets in the consolidated balance sheets. The increase in cost method investments is due to an acquisition made in the third quarter of 2017. Earnings from equity method investments, which are included in non-operating income and expense, and dividends received from equity method investments consisted of the following: Three Months Ended Nine Months Ended (in millions) 2017 2016 2017 2016 Earnings from equity method investments $ 2.6 $ 2.3 $ 6.3 $ 6.2 Dividends received from equity method investments $ 0.3 $ 0.5 $ 0.8 $ 6.1 There were no dividends received from cost method investments for the three months ended September 30, 2017 and 2016.

Debt	Debt Debt outstanding consisted of the following: (in millions) September 30, December 31, 2016 Senior Secured Term Loan B, payable in quarterly installments through April 9, 2023, and periodic variable interest at LIBOR or alternate base rate, plus applicable margin (3.24% at September 30, 2017 and 3.52% at December 31, 2016), including original issue discount and deferred financing fees of $6.5 million and $3.9 million, respectively, at September 30, 2017, and original issue discount and deferred financing fees of $7.6 million and $4.4 million, respectively, at December 31, 2016 $ 1,976.0 $ 1,984.6 Senior Secured Term Loan A, payable in quarterly installments through August 9, 2022, and periodic variable interest at LIBOR or alternate base rate, plus applicable margin (2.74% at September 30, 2017 and 2.77% at December 31, 2016), including original issue discount and deferred financing fees of $1.5 million and $0.3 million, respectively, at September 30, 2017, and original issue discount and deferred financing fees of $0.7 million and $0.2 million, respectively, at December 31, 2016 398.2 375.7 Other notes payable 10.9 14.2 Capital lease obligations 1.4 1.1 Total debt 2,386.5 2,375.6 Less short-term debt and current portion of long-term debt (34.4 ) (50.4 ) Total long-term debt $ 2,352.1 $ 2,325.2 Excluding potential additional principal payments due on the senior secured credit facility based on excess cash flows of the prior year, scheduled future maturities of total debt at September 30, 2017 , were as follows: (in millions) September 30, 2017 $ 8.1 2018 34.1 2019 36.4 2020 43.3 2021 39.9 Thereafter 2,236.9 Unamortized original issue discounts and unamortized deferred financing fee (12.2 ) Total debt $ 2,386.5 Senior Secured Credit Facility On June 15, 2010, we entered into a senior secured credit facility with various lenders. This facility has been amended several times and currently consists of the Senior Secured Term Loan A, the Senior Secured Term Loan B, and the Senior Secured Revolving Line of Credit. On August 9, 2017, we refinanced and amended certain provisions of our senior secured credit facility. Amendments to the Senior Secured Term Loan B included a 0.50% reduction in the applicable margin. Amendments to the Senior Secured Term Loan A included an extension of the maturity date from June 2020 to August 2022, a reduction in the applicable margin depending on our total net leverage ratio, an increase in borrowing to $400.0 million , and a reduction in the scheduled principal repayments. Amendments to the Senior Secured Revolving Line of Credit included an extension of the maturity date from June 2020 to August 2022, a reduction in the applicable margin depending on our total net leverage ratio, a reduction in the annual commitment fee on the unused borrowings, and an increase in the commitment amount to $300.0 million . Other key provisions include changes in incremental borrowing limits and a reduction in the financial covenant test not to exceed a senior secured net leverage ratio of 5.5 -to-1. The refinancing resulted in $5.6 million of refinancing fees and other net costs expensed and recorded in other income and expense in the consolidated statements of income in the third quarter of 2017. On January 31, 2017, we refinanced and amended certain provisions of our Senior Secured Term Loan B. The refinancing resulted in $5.0 million of refinancing fees and other net costs expensed and recorded in other income and expense in the consolidated statements of income in the first quarter of 2017. During the third quarter, we repaid the $45.0 million outstanding balance on the Senior Secured Revolving Line of Credit. As of September 30, 2017 , we could have borrowed up to the entire $300.0 million available. TransUnion also has the ability to request incremental loans up to the greater of an additional $675.0 million and 100% of Consolidated EBITDA, and may incur additional incremental loans so long as the senior secured net leverage ratio does not exceed 4.25 -to-1.0, subject to certain additional conditions and commitments by existing or new lenders to fund any additional borrowings. With certain exceptions, the senior secured credit facility obligations are secured by a first-priority security interest in substantially all of the assets of Trans Union LLC, including its investment in subsidiaries. The senior secured credit facility contains various restrictions and nonfinancial covenants, along with a senior secured net leverage ratio test. The nonfinancial covenants include restrictions on dividends, investments, dispositions, future borrowings and other specified payments, as well as additional reporting and disclosure requirements. The senior secured net leverage test must be met as a condition to incur additional indebtedness, make certain investments, and may be required to make certain restricted payments. The senior secured net leverage ratio must not exceed 5.5 -to-1 at any such test date. As of September 30, 2017 , we were in compliance with all debt covenants. On December 18, 2015, we entered into interest rate cap agreements with various counter-parties that effectively cap our LIBOR exposure on a portion of our existing senior secured term loans or similar replacement debt at 0.75% beginning June 30, 2016. We have designated these cap agreements as cash flow hedges. The current aggregate notional amount under these agreements is $1,491.4 million and will decrease each quarter until the agreement terminates on June 30, 2020. In July 2016, we began to pay the various counter-parties a fixed rate on the outstanding notional amounts of between 0.98% and 0.994% and receive payments to the extent LIBOR exceeds 0.75% . The interest rate caps are recorded on the balance sheet at fair value. The effective portion of changes in the fair value of the interest rate cap agreements is recorded in other comprehensive income. The ineffective portion of changes in the fair value of the caps, which is due to, and will continue to result from, the cost of financing the cap premium, is recorded in other income and expense. The effective portion of the change in the fair value of the caps resulted in an unrealized gain of $0.5 million and $0.4 million , net of tax, recorded in other comprehensive income for three and nine months ended September 30, 2017, respectively. The effective portion of the change in the fair value of the caps resulted in an unrealized loss of $0.2 million and $21.7 million , net of tax, recorded in other comprehensive income for the three and nine months ended September 30, 2016, respectively. The ineffective portion of the change in the fair value of the caps resulted in a loss of $0.1 million and $0.2 million recorded in other income and expense for three and nine months ended September 30, 2017 , respectively. The ineffective portion of the change in the fair value of the caps resulted in a gain of $0.1 million and a loss of $0.9 million recorded in other income and expense for the three and nine months ended September 30, 2016, respectively. In accordance with ASC 815, the fair value of the interest rate caps at inception is reclassified from other comprehensive income to interest expense in the same period the interest expense on the underlying hedged debt impacts earnings. Based on how the fair value of interest rate caps are determined, the earlier interest periods have lower fair values at inception than the later interest periods, resulting in less interest expense being recognized in the earlier periods compared with the later periods. Any payments we receive to the extent LIBOR exceeds 0.75% is also reclassified from other comprehensive income to interest expense in the period received. Interest expense reclassified from other comprehensive income to interest expense related to the fair value of the portion of the caps expiring in the three and nine months ended September 30, 2017 was $0.8 million and $3.3 million , respectively. Interest expense reclassified from other comprehensive income to interest expense related to the fair value of the portion of the caps expiring in the three and nine months ended September 30, 2016 was $0.5 million in each period. We expect to reclassify approximately $3.9 million from other comprehensive income to interest expense related to the fair value of the portion of the caps expiring and payments received to the extent LIBOR exceeds 0.75% in the next twelve months. Fair Value of Debt As of September 30, 2017 , the fair value of our variable-rate Senior Secured Term Loan A, excluding original issue discounts and deferred fees, approximates the carrying value. As of September 30, 2017, the fair value of our Senior Secured Term Loan B, excluding original issue discounts and deferred fees, was $1,983.9 million . The fair values of our variable-rate term loans are determined using Level 2 inputs, and quoted market prices for the publicly traded instruments.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share represents income available to common stockholders divided by the weighted average number of common shares outstanding during the reported period. Diluted earnings per share reflects the effect of the increase in shares outstanding determined by using the treasury stock method for awards issued under our incentive stock plans. For the three and nine months ended September 30, 2017 , there were less than 0.1 million anti-dilutive stock-based awards outstanding. In addition, there were no contingently issuable stock-based awards outstanding that were excluded from the diluted earnings per share calculation because the contingencies had not been met. For the three and nine months ended September 30, 2016 , there were less than 0.1 million anti-dilutive stock-based awards outstanding. In addition, there were 5.9 million contingently issuable stock-based awards outstanding that were excluded from the diluted earnings per share calculation because the contingencies had not been met. Basic and diluted weighted average shares outstanding and earnings per share were as follows: Three Months Ended Nine Months Ended (in millions, except per share data) 2017 2016 2017 2016 Earnings per share - basic Earnings available to common stockholders $ 68.8 $ 41.2 $ 196.0 $ 71.0 Weighted average basic shares outstanding 182.2 182.7 182.3 182.5 Earnings per share - basic $ 0.38 $ 0.23 $ 1.08 $ 0.39 Earnings per share - diluted Earnings available to common stockholders $ 68.8 $ 41.2 $ 196.0 $ 71.0 Weighted average basic shares outstanding 182.2 182.7 182.3 182.5 Dilutive impact of stock-based awards 7.0 2.1 7.5 1.9 Weighted average dilutive shares outstanding 189.2 184.8 189.8 184.4 Earnings per share - diluted $ 0.36 $ 0.22 $ 1.03 $ 0.39

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended September 30, 2017, we reported an effective tax rate of 31.0% , which was lower than the 35% U.S. federal statutory rate due primarily to the impact of excess tax benefits related to the adoption of ASU No. 2016-09. Effective January 1, 2017, this new guidance requires any excess tax benefits for share-based payment award transactions to be recorded in the income statement. Accordingly, we recognized excess tax benefits on stock option exercises, which resulted in a decrease in tax expense of $5.0 million , partially offset by an increase of $2.2 million in state tax expense including changes in state tax rates. For the nine months ended September 30, 2017, we reported an effective tax rate of 25.2% , which was lower than the 35% U.S. federal statutory rate due primarily to the excess tax benefits on stock option exercises of $28.1 million and the first quarter 2017 ownership structure change for certain international subsidiaries which resulted in a decrease in income tax expense of $5.2 million , partially offset by an increase of $3.2 million in state tax expense including changes in state tax rates. For the three months ended September 30, 2016, we reported an effective tax rate of 41.3% , which was higher than the 35% U.S. federal statutory rate due primarily to the tax expense on unremitted foreign earnings not considered permanently reinvested, the impact of valuation allowances on the losses of certain foreign subsidiaries, and changes in state tax assumptions. For the nine months ended September 30, 2016, we reported an effective tax rate of 43.1% , which was higher than the 35% U.S. federal statutory rate due primarily to the tax expense on unremitted foreign earnings not considered permanently reinvested, the impact of valuation allowances on the losses of certain foreign subsidiaries, and changes in state tax assumptions. The total amount of unrecognized tax benefits was $7.6 million as of September 30, 2017, and $4.8 million as of December 31, 2016. These same amounts would affect the effective tax rate, if recognized. The accrued interest payable for taxes was insignificant as of September 30, 2017 and December 31, 2016. There was no significant liability for tax penalties as of September 30, 2017 or December 31, 2016. We are regularly audited by federal, state and foreign taxing authorities. 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. An estimate of the range of the increase or decrease in unrecognized tax benefits due to audit results cannot be made at this time. Generally, tax years 2008 and forward remain open for examination in some state and foreign jurisdictions, and tax years 2012 and forward remain open for examination for U.S. federal purposes.

Segment Reporting [Abstract]
Operating Segments	Reportable Segments 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,” included in our audited financial statements for the year ended December 31, 2016 , included in our Annual Report on Form 10-K filed with the SEC on February 15, 2017. We evaluate the performance of segments based on revenue and operating income. The following is a more detailed description of the three reportable segments and the Corporate unit, which provides support services to each segment: U.S. Information Services U.S. Information Services (“USIS”) provides consumer reports, risk scores, analytical and decisioning services to businesses. These businesses use our services to acquire new customers, assess consumer ability to pay for services, identify cross-selling opportunities, measure and manage debt portfolio risk, collect debt, verify consumer identities and investigate potential fraud. The core capabilities and delivery platforms in our USIS segment allow us to serve a broad set of customers and business issues. We offer our services to customers in financial services, insurance, healthcare, and other industries. International The International segment provides services similar to our USIS segment to businesses in select regions outside the United States. Depending on the maturity of the credit economy in each country, services may include credit reports, analytics and decisioning services, and other value-added risk management services. In addition, we have insurance, business and automotive databases in select geographies. 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 by our Consumer Interactive segment that help consumers proactively manage their personal finances. Consumer Interactive Consumer Interactive offers solutions that help consumers manage their personal finances and take precautions against identity theft. Services in this segment include credit reports and scores, credit monitoring, fraud protection and resolution, and financial management. Our products are provided through user-friendly online and mobile interfaces and are supported by educational content and customer support. Our Consumer Interactive segment serves consumers through both direct and indirect channels. Corporate In addition, Corporate provides support services for each of the segments, holds investments, and conducts enterprise functions. Certain costs incurred in Corporate that are not directly attributable to one or more of the segments remain in Corporate. These costs are typically enterprise-level costs and are primarily administrative in nature.

Loss Contingencies [Line Items]
Commitments and Contingencies Disclosure	Contingencies Litigation In view of the inherent unpredictability of litigation and regulatory matters, particularly where the damages sought are substantial or indeterminate or when the proceedings or investigations are in the early stages, we cannot determine with any degree of certainty the timing or ultimate resolution of litigation and regulatory matters or the eventual loss, fines, penalties or business impact, if any, that may result. We establish reserves for litigation and regulatory matters when those matters present loss contingencies that are both probable and can be reasonably estimated. The actual costs of resolving litigation and regulatory matters, however, may be substantially higher than the amounts reserved for those matters, and an adverse outcome in certain of these matters could have a material adverse effect on our consolidated financial statements in particular quarterly or annual periods. The following discussion describes material developments in previously disclosed material legal proceedings that occurred in the nine months ended September 30, 2017. Refer to Part I, Item 3 of our Annual Report on Form 10-K for the year ended December 31, 2016, Part II, Item 1 of our Quarterly Report on Form 10-Q for the Quarterly Period ended March 31, 2017, and Part II, Item 1 of our Quarterly Report on Form 10-Q for the Quarterly Period ended June 30, 2017, for a full description of our material pending legal proceedings. On June 21, 2017, the jury in Ramirez returned a verdict in favor of a class of 8,185 individuals in the amount of approximately $8.1 million ( $984.22 per class member) in statutory damages and approximately $52.0 million ( $6,353.08 per class member) in punitive damages. Plaintiff’s counsel has not provided any estimate of attorneys’ fees and costs that they will seek in connection with this verdict as permitted by law. The timing and outcome of the ultimate resolution of this matter is uncertain. We have posted a bond at nominal cost to stay the execution of the judgment pending resolution of post-judgment motions that were filed with the trial court and the expectation of a subsequent appeal. Despite the jury verdict, we continue to believe that we have not willfully violated any law and have meritorious grounds for seeking modification of the judgment at the trial court or on appeal. Given the complexity and uncertainties associated with the outcome of the post-trial proceedings and any subsequent appeals, there is a wide range of potential results, from vacating the judgment in its entirety to upholding some or all aspects of the judgment. As of September 30, 2017, we have recorded a charge for this matter equal to our current estimate of probable losses for statutory damages, net of amounts we expect to receive from our insurance carriers, the impact of which is not material to our financial condition or results of operations. We have not, however, recorded an accrual with respect to the punitive damages awarded by the jury since it is not probable, based on current legal precedent, that an award for punitive damages in conjunction with statutory damages for the alleged conduct will survive the post-judgment actions. We currently estimate, however, that the reasonably possible loss in future periods for punitive damages falls within a range from zero to something less than the amount of the statutory damages awarded by the jury. This estimate is based on currently available information. As available information changes, our estimates may change as well. We believe we will have some level of insurance coverage for the damage award and the legal fees and expenses we have incurred and will incur for defending this matter should this matter be unfavorably resolved against us after exhaustion of our post-judgment options. The Ramirez matter involved facts that are not related to the other OFAC Alert Service matters. As a result, we do not believe the jury verdict in Ramirez will have any bearing on Miller or Larson , which are still pending before different courts.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Any reference in this report to “the Company,” “we,” “our,” “us,” and “its’” are to TransUnion and its consolidated subsidiaries, collectively. The accompanying unaudited consolidated financial statements of TransUnion and subsidiaries 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, 2017 . 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, 2016 , filed with the Securities and Exchange Commission (“SEC”) on February 15, 2017.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements of TransUnion include the accounts of TransUnion and all of its controlled subsidiaries. Investments in unconsolidated entities in which the Company is able to exercise significant influence are accounted for using the equity method. Nonmarketable investments in unconsolidated entities in which the Company 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 consolidated financial statements.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements On March 30, 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU simplifies several aspects of the accounting for share-based payment award transactions, including income tax consequences, classification of awards, and classification on the statement of cash flows. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods therein. The provisions in the new guidance related to income taxes that impacted us were adopted prospectively. As a result of this guidance, beginning January 1, 2017, we record excess tax benefits as a reduction to income tax expense and reflect excess tax benefits as operating cash flows. Depending on the exercise pattern of our remaining outstanding options, and the value of our stock on the exercise dates of our stock options and vest dates of our restricted stock units relative to the corresponding fair value of those awards on their grant dates, there could be a material impact on our future income tax expense. Recent Accounting Pronouncements Not Yet Adopted On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) . During 2016, the FASB issued several additional ASU's related to revenue recognition. This series of comprehensive guidance will replace all existing revenue recognition guidance and is effective for annual reporting periods beginning after December 15, 2017, and interim periods therein. We will adopt this standard beginning January 1, 2018, and will use the modified retrospective approach, with the cumulative effect recognized in the opening balance of retained earnings. We have categorized our various contract revenue streams in alignment with the new standard. We are in the process of finalizing our review of contracts and have applied the five-step model specified by the new guidance. The five-step model includes: (1) determination of whether a contract, an agreement between two or more parties that creates legally enforceable rights and obligations, exists; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when (or as) the performance obligation is satisfied. Additionally, we are in the process of assessing the impact of the new standard on our disclosures and internal controls. We continue to evaluate the impact this guidance will have on our consolidated financial statements and disclosures and prepare for the adoption of the standard on January 1, 2018, including readying our internal processes and control environment for new requirements, particularly around enhanced disclosures. At this point, we have not identified anything that we believe will have a material impact on how we record revenue, but our conclusions will continue to evolve as we finalize our contract reviews and evaluation. The FASB has issued, and may issue in the future, interpretative guidance, which may impact our evaluation. We believe that we are following an appropriate timeline to allow for proper revenue recognition, presentation and disclosures upon adoption of this new standard on January 1, 2018. On January 5, 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU is intended to improve the recognition and measurement of financial instruments. Among other things, the ASU requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. This guidance is effective for fiscal years beginning after December 15, 2017, and interim periods therein. We are currently assessing the impact this guidance will have on our consolidated financial statements. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . This ASU, among other things, will require lessees to record a lease liability, which is an obligation to make lease payments arising from a lease, and right-of-use asset, which is an asset that represents the right to use, or control the use of, a specified asset for the lease term, for all long-term leases. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently assessing the impact this guidance will have on our consolidated financial statements. On June 16, 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. In addition, these amendments require the measurement of all expected credit losses for financial assets, including trade accounts receivable, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This guidance is effective for annual reporting periods beginning after December 15, 2019, including interim period therein. We are currently assessing the impact this guidance will have on our consolidated financial statements. On August 26, 2016 the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods therein. We are currently assessing the impact this guidance will have on our consolidated statements of cash flows. On August 28, 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new standard is intended to improve and simplify accounting rules around hedge accounting. The guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods therein. We are currently assessing the impact this guidance will have on our consolidated financial statements.
