You have the right to dispute any information in your credit report that's inaccurate, incomplete, or you believe can't be verified. When you order your credit report, you'll receive instructions on how to dispute credit report information. Credit reports ordered online typically come with instructions for making disputes online, but you can also make disputes over the phone and through the mail.
If you find information that is incorrect, you can file a dispute. Remember too, that items on your credit report that you don't recognize could also be potential signs of fraudulent activity — someone working to secure credit in your name for their own use. Make sure you're clear on items that could potentially be fraudulent, versus those that may simply be inaccurate.
