Next, place a fraud alert with all three credit bureaus. This alert tells lenders to verify your identity before opening new accounts. You can file the alert online, by phone, or by mail. The initial alert lasts 90 days; an extended alert lasts seven years if you're an identity theft victim.

Monitor your credit regularly going forward. Consider placing a credit freeze with all three bureaus, which prevents anyone from opening accounts in your name without your PIN. Freezes cost nothing and remain in place until you
