Contact the major credit bureaus & file a report with local police:

If you suspect fraud on your accounts, you can request that the three main credit bureaus place a short or long-term “fraud alert” on your credit file. This alert requires creditors to verify your identity before opening any new accounts in your name or changing any existing accounts. You will only need to contact one bureau, which will notify the others.

Credit bureaus must provide victims of identity theft a free copy of their credit report. You should request one from each bureau, as the information can differ. Review your credit reports carefully for fraudulent activity. If fraud has occurred, notify the credit bureau and the companies where accounts were opened to report the fraud directly.

Once a dispute has been resolved, the credit bureaus you contacted will send you another copy of your credit report. Review the report to make sure that all fraudulent activity has stopped and your file has been corrected.

Contact your local police department if you suspect that your personal information was stolen. A police report may lend credibility to your case when dealing with creditors, who may require proof of criminal activity.

Contact other agencies as appropriate:

  • Federal Trade Commission Complaints: The nation's consumer protection agency, collects complaints about companies, business practices, and identity theft.
    If you would like to lodge a complaint, go here.
  • Postal Inspection Service: If you believe your mail was stolen or redirected, notify your local post office.
  • Social Security Fraud Hotline:800-269-0271. If you suspect someone is using your Social Security number for fraudulent purposes, call the hotline.
  • Department of Motor Vehicles (DMV): If you believe someone is trying to get a driver’s license or identification card using your name and information, contact your local DMV.
