What to do now

Steps chosen from the information listed in the official filings. Your own letter may list more.

  1. A credit freeze stops new credit accounts being opened in your name. It is free by law and you can lift it when you need credit: Equifax, Experian and TransUnion.

  2. An IP PIN stops someone else filing a tax return with your Social Security number. Get one from the IRS at irs.gov.

  3. Review recent transactions, ask about account alerts, and ask whether a new account number is recommended.

  4. Check the Explanation of Benefits (EOB) statements from your insurer for visits, prescriptions or claims you do not recognize, and contact your insurer about anything unfamiliar.

  5. Ask your state's DMV what it recommends when a driver's license number has been exposed. Find your state's agency at USA.gov.

  6. Scammers often contact people after a breach, pretending to be the organization, a bank or a government agency. Do not give your Social Security number, passwords or codes to anyone who contacts you first.

  7. You can get free credit reports from all three bureaus at AnnualCreditReport.com, the official site.

  8. The Federal Trade Commission's IdentityTheft.gov gives you a personal recovery plan.
