Step 1: Obtain your free credit reports
Obtaining your credit report is the first step in disputing any inaccurate or wrong information which may appear on it. Federal law requires the three national credit reporting agencies, Equifax, Experian, and Trans Union, to provide you with a free credit report every year. Most likely, each of these credit reporting agencies has a credit file on you. Get all three of your credit reports.

You can get your free credit reports at AnnualCreditReport.com. This is the only official site to help consumers obtain their free credit report. You may contact the credit reporting agencies directly, but consumer beware! These credit reporting agencies own businesses which easily trick the consumer into buying their credit scores rather than providing the consumer with their actual free credit report (legally known as the "consumer report").

Step 2: Initiate dispute with the credit reporting agency
Dispute errors on your credit report by using the FTC's sample complaint letter. Make copies of supportive documentation and mail your dispute to the credit reporting agency reporting the error(s). Mail your dispute letter & enclosures via certified mail - return receipt to:

Trans Union
Consumer Disclosure Center
P.O. Box 2000

Step 3: Initiate dispute with the furnisher
Contact the furnisher of the inaccurate information. Use the FTC's sample complaint letter to use to dispute inaccurate information with providers.

Step 4: Wait for response
Credit reporting agencies must investigate disputes made by consumers. Thirty (30) days after the dispute is initiated, credit reporting companies are required (by law) to provide consumers with the results. The results should be accompanied by a free credit report. If the disputed is not resolved, consider seeking legal action.
