Consumers should dispute errors in writing directly with the credit bureau that is reporting the incorrect information. This written notification triggers an official investigation by the bureau, which must respond within 30 days.

“To dispute an error on your credit report, write a letter to the credit reporting company identifying each item in your report you dispute. Include copies of documents that support your position.”
