What to do if you suspect credit card fraud. For cards issued by a financial institution, contact your financial institution either by phone, web site, or mobile app. Your issuer may want to cancel your current card and issue you a new one. Check with your issuer to verify that your mailing address has not been changed.

If you still have your card but fraudulent purchases have been made, call your issuer to report the fraud and request a new card. Also, contact the credit bureaus to let them know that fraud has occurred. A "Fraud Alert" message will be placed on your file. You should also request a copy of your credit report and review it carefully.

  • Contact your bank or credit card company to cancel your card and request a new one.
  • Review your transactions regularly. Make sure no one misused your card.
    • If you find fraudulent charges, call the fraud department and get them removed.
  • If you have automatic payments set up, update them with your new card number.
  • Check your credit report at .
