What to do now

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

1. Enroll in the free credit monitoring

   Lennar Corporation offered free credit monitoring for 24 months through Kroll. Use the enrollment code printed in your letter. Never share that code with anyone who contacts you.

2. Freeze your credit at all three bureaus

   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.

3. Get an IRS Identity Protection PIN

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

4. Contact your bank or credit union

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

5. 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.

6. Contact your state motor vehicle agency

   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.

7. 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.

8. Check your credit reports

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

9. Report identity theft if you see signs of it

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