If you do find that you've become a victim of identity fraud, here are a few steps you should take immediately.

• Contact Banks and Creditors. As soon as you've learned of an unauthorized use of your identity, contact all your credit card issuers and banks to report the fraud. Cancel any existing accounts and obtain new account information.
• File a Police Report. Under the Identity Theft and Assumption Deterrence Act of 1998, identity fraud is a federal crime. Among other rights, the law gives you the right to file a police report. Doing this as soon as possible will help you in disputing fraudulent credit card charges and entries. 
• Contact Credit Bureaus. You should immediately obtain your credit report from all three major credit reporting bureaus —Equifax, Experian and TransUnion. By federal law, the credit reporting bureaus must provide you with a free copy of your credit report if you've been a victim of fraud. Write to the bureaus to dispute any items that you do not recognize. Explain that you have been a fraud victim and specify the accounts that weren't opened by you and the charges that you did not make. Also, ask the bureaus to have a fraud watch put on your account.
• Contact the FTC. The Identity Theft and Assumption Deterrence Act of 1998 appoints the Federal Trade Commission to serve as an advocate for identity fraud victims, to help them find the right law enforcement agency, and to provide other assistance. As soon as you suspect that you're an identity fraud victim, you should contact the FTC at 1-877-FTC-HELP (382-4357) or 1-877-ID-THEFT (438-4338) to explain your case.
