Also, consider calling the three major credit bureaus. Ask them to place a fraud notice in your file, so that lenders and other users of credit reports will be warned to be careful before approving a new credit card in your name. Two of the three credit bureaus publicize the toll-free numbers for their fraud department: Experian at (800) 301-7195 and Trans Union at (800) 680-7289. Equifax asks that you first contact your creditor or the police in order to get the phone number for its fraud unit.
