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.
-
An IP PIN stops someone else filing a tax return with your Social Security number. Get one from the IRS at irs.gov.
-
Review recent transactions, ask about account alerts, and ask whether a new account number is recommended.
-
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.
-
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.

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

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