When it comes to credit report errors, a new federal agency has your back. By Joan Goldwasser, Senior Reporter August 31, 2012 Big Brother is watching ... your finances. The three major credit-reporting companies—Equifax, Experian and TransUnion—maintain files on roughly 220 million Americans. If the information about you is not accurate, you could be forced to pay a higher interest rate, or you could be rejected for a credit card or loan.

According to Richard Cordray, the CFPB director, the bureau will examine the accuracy of the data the agencies receive, how the companies maintain and assemble the information in consumers’ credit reports, and how the agencies manage dispute resolution. The CFPB’s tough new oversight is welcome news. By some estimates, as many as 25% of credit reports contain errors. A yearlong investigation by the Columbus Dispatch of complaints involving credit reports on file with the big three agencies found bank-approved short sales listed as foreclosures, paid-off car loans listed as repossessions, and closed credit card accounts listed as delinquent. So you still need to be vigilant about checking your credit report. To request a free report, go to www.annualcreditreport.com.
