What to do now
- Freeze your credit for free at Equifax, Experian and TransUnion, and request an IRS Identity Protection PIN at irs.gov to block fraudulent tax returns in your name.
- Contact your state DMV to ask whether your license number should be replaced, and watch for accounts opened with your ID.
- Consider reporting the exposure to the U.S. State Department if you see suspicious activity; a new passport invalidates the old number.
- Call your bank, ask about extra monitoring or a new account number, and review statements for small unknown charges.
- Review the Explanation of Benefits statements from your insurer for services you never received.
- Ask your insurer whether a new member ID can be issued, and check claims made under your policy.
