What should you do?
Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.
Review your credit reports and consider a free credit freeze if identity information could support new-account fraud.

Choose actions that match the information involved. If you find signs that someone is using your identity, the Federal Trade Commission provides a personal recovery plan at IdentityTheft.gov.
