Exhibit 99.3

The following unaudited pro forma condensed combined financial data give effect to the Acquisition and related financings as if they had been completed on September 30, 2012 with respect to the pro forma balance sheet data and as of January 1, 2011 with respect to the pro forma statement of income data.

It should be noted that Equifax and CSC Credit Services, Inc. have different fiscal year ends. Accordingly, the selected unaudited pro forma income statement data for the calendar year ended December 31, 2011 have been developed from Equifax’s historical consolidated income statement data for the year then ended and CSC Credit Services, Inc.’s historical consolidated income statement data for the year ended March 31, 2012. The selected unaudited pro forma income statement data for the nine months ended September 30, 2012 have been developed from Equifax’s historical consolidated income statement data for the nine calendar months then ended and the unaudited historical results of CSC Credit Services, Inc. for the nine months ended September 30, 2012, which were derived from CSC Credit Services, Inc.’s unaudited historical results for the three months ended March 31, 2012 plus the unaudited six months ended September 30, 2012. The selected unaudited pro forma balance sheet data have been developed from Equifax’s historical consolidated balance sheet data as of September 30, 2012 and CSC Credit Services, Inc.’s historical consolidated balance sheet data as of September 30, 2012.

The Acquisition will be accounted for under the purchase method of accounting. Under purchase accounting, the total purchase cost will be allocated to the tangible and intangible assets acquired by Equifax based upon their respective fair values as of the closing of the Acquisition based on valuations and other studies, which are not yet available. A preliminary allocation of the purchase cost has been made to major categories of assets in the pro forma condensed combined financial data set forth below based on estimates. The actual allocation of purchase cost and the resulting effect on income from operations may differ materially from the pro forma amounts included herein.

The following unaudited pro forma condensed combined financial data are presented for illustrative purposes only and are not necessarily indicative of what Equifax’s actual financial position or results of operations would have been had the Acquisition and related financings been completed on the dates indicated above. In addition, the following unaudited pro forma condensed combined financial data do not purport to project the future financial position or results of operations of the combined company. A number of factors may affect our results. See the specific factors set forth in “Risk Factors” above and in our annual report on Form 10-K for the year ended December 31, 2011 and our subsequent quarterly reports on Form 10-Q incorporated by reference in this prospectus supplement.
