Is this call really from American Express?
You can't tell from caller ID alone: scammers routinely make a real American Express number show up on your screen. The safe move is to hang up and call American Express 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.
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.
