You are entitled to receive one free credit report every 12 months from each of the nationwide consumer credit reporting companies—Equifax, Experian and TransUnion. This free credit file can be requested through Annual Credit Report or by contacting the companies directly by phone or by mail as listed below.

To process your request, you will need to provide specific information, such as your name, current and previous addresses, telephone number, social security number, and date of birth. Also, to verify your identity, other information such as a copy of your driver's license, utility bill(s), or bank statement may be required. Keep in mind that the three large bureaus do not necessarily share information with each other.

The content of your credit report can be different at each bureau, so it's a good idea to request copies from each one.
