What to do now

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

Review your health insurance statements

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.
Watch for phishing calls, texts and emails

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.
Check your credit reports

You can get free credit reports from all three bureaus at AnnualCreditReport.com, the official site.
Report identity theft if you see signs of it

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