The Federal Trade Commission explains your rights to access consumer reporting information that affects your credit score. You can access your credit report for free from each of the 3 credit bureaus once a year. The best way to use this to your advantage is to pull one credit report every 4 months from one of the credit bureaus: Equifax, TransUnion, or Experian. By the end of a year you will have used your 3 allotments. The only official website designated for this purpose is www.annualcreditreport.com.
