If you'd like to request your credit file from any of the credit bureaus, you need to send them a request letter to provide you with one. Here's a sample format of such a letter.
Date
Dear Sir/Madam,
I would like to formally request a copy of my most recent credit report from you. The FCRA requires that upon request, a credit bureau should furnish an individual with a copy of his credit file after validating the requestor's identity. The documents that verify my identity are attached.
Please send me a copy of my credit file as soon as possible.
Sincerely,
Your Signature Your Name
