Because a mistake on your credit report can negatively impact your credit score, it’s important to monitor your credit report from each credit reporting agency on a regular basis and make sure all versions are accurate.

If you find an error on your credit report, your first step should be to contact the credit reporting agency, either online or by mail, to indicate that you are disputing information on your report. The credit reporting agency usually must investigate the dispute within 30 days of receiving it. Once the investigation is complete, the agency must provide you with written results of its investigation. If the credit reporting agency concludes that your credit report does contain errors, the information on your report must be removed or corrected, and you’ll receive an updated version of your credit report for free.

If the investigation does not resolve the issue to your satisfaction, you can add a 100-word consumer statement to your credit file. Even though creditors are not required to take consumer statements into consideration when evaluating your creditworthiness, the statement can at least give you a chance to tell your side of the story.

If you believe that your credit report error is the result of identity theft, you may need to take additional steps to resolve the issue, such as placing a fraud alert or security freeze on your credit report. You can visit the Federal Trade Commission (FTC) website at ftc.gov for more information on the various identity theft protections that might be available to you.

Finally, due to the amount of paperwork and steps involved, fixing a credit report error can often be a time-consuming and emotionally draining process. If at any time you believe that your credit reporting rights are being violated, you can file a complaint with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov.
