This is the contact information for all 3 major credit bureaus. This is very important information to have.
Also, did you know that you can freeze your credit report so that no one can see it without your permission? Just contact the credit bureau you want frozen and it's done. Remember to save your security code for when you choose to let someone see your report.
From my experience, Equifax and Trans Union are the better credit bureaus.
