Has the Equifax credit report error affected you? Here's how to find out.

Equifax this week admitted that it misreported some consumers' credit scores, potentially affecting applications for mortgages, auto loans or credit cards.

The Wall Street Journal on Tuesday reported that, between March 17 and April 6, the company sent out millions of incorrect credit scores for consumers. Yet Equifax said that less than 300,000 customers had their credit scores change by 25 points or more in either direction. Errors in how different elements in a credit report are weighted led to the swings, the company said.

A Florida woman who was forced into a pricey car loan as a result of an incorrect Equifax score is now suing the company. The lawsuit, which is seeking class-action status, notes that over the three-week period Equifax sent out erroneous scores, 25 million credit reports were pulled from the three credit-reporting bureaus. Given those figures, millions of Americans could have been affected by the error, the suit claims.
