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.
- Call your bank, ask about extra monitoring or a new account number, and review statements for small unknown charges.
- Ask the school which records were involved and whether any account credentials need to be reset.
- Get your free credit reports at AnnualCreditReport.com and look for accounts you do not recognize.
- Call the Yu Ming Charter School helpline at 1-833-931-8488 if you have questions about your letter.
