Review Financial Statements
Carefully examine bank accounts, credit card statements, and other financial records for suspicious activity.
Monitor Your Credit Reports
Request and review credit reports from the major credit bureaus for unauthorized accounts or inquiries.
Consider a Fraud Alert
A fraud alert can notify lenders to verify your identity before opening new accounts in your name.
Freeze Your Credit
A credit freeze can help prevent criminals from opening new lines of credit using your personal information.
