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. 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.

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

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