What address should I use for Medicare?

You should use your permanent residential address (where you actually live for at least half the year) for Medicare.

Why Your Address Matters

  • Plan Availability: Your physical location determines which Medicare Advantage (Part C), Prescription Drug (Part D), or Medigap plans you can buy.
  • Cost Changes: Medigap prices can vary based on your specific zip code.
  • No Permanent Home: If you do not have a fixed home, you can use a post office box, a shelter, a clinic, or the address where you regularly receive mail.

  • Online: Log into your my Social Security account.
  • Phone: Call Social Security at 1-800-772-1213 (TTY 1-800-325-0778).
  • In Person: Visit your local Social Security office.
