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.
- 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.
- Get your free credit reports at AnnualCreditReport.com and look for accounts you do not recognize.
- Call the The Thayer Hotel helpline at 1-866-653-4261 if you have questions about your letter.
