Is this call really from Medicare?
You can't tell from caller ID alone: scammers routinely make a real Medicare number show up on your screen. The safe move is to hang up and call Medicare back on a number from the table above (or from the back of your card or an official letter), never on a number the caller gives you.
What Medicare says about how it contacts you
- Medicare never calls to sell you anything and never visits your home. It only calls asking for personal information in limited cases, such as returning a call you made. (medicare.gov)
Treat these as red flags whoever the caller claims to be: pressure to act right now, threats of arrest, deportation or a frozen account, requests for gift cards, crypto or a wire transfer, and any request for a one-time passcode, PIN or full password.

How to call Medicare from abroad
The medicare.gov pages we checked don't list a separate number for callers outside the US, and toll-free numbers usually can't be reached from a foreign phone network.
Toll-free numbers are paid for by the organization, and that arrangement mostly stops at the border, so a foreign mobile usually gets an error. Our guide to calling 1-800 numbers from outside the US covers the ways around it.
