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.
- Consider reporting the exposure to the U.S. State Department if you see suspicious activity; a new passport invalidates the old number.
- Your date of birth is often used to verify identity: add a fraud alert to your credit file so lenders must confirm it is really you.
- Call your bank, ask about extra monitoring or a new account number, and review statements for small unknown charges.
- Ask your card issuer to replace the card and review recent transactions; card fraud is usually refunded if reported quickly.
- Expect targeted phishing that mentions this incident: do not click links in unexpected emails about the breach.
- Be wary of calls or texts that mention this incident and ask for codes or payment.
- Request an IRS Identity Protection PIN and watch for IRS letters about returns you did not file.
- Get your free credit reports at AnnualCreditReport.com and look for accounts you do not recognize.
- Call the Marin Housing Authority helpline at 1-855-260-0593 if you have questions about your letter.
