Is this call really from Santander UK?
You can't tell from caller ID alone: scammers routinely make a real Santander UK number show up on your screen. The safe move is to hang up and call Santander UK 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 Santander UK says about how it contacts you
- Santander will never ask for your PIN, Online Banking passwords or one-time passcodes. (santander.co.uk)
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 Santander UK from abroad
From outside the UK, call +44 1512 648 725 (Card fraud / lost credit card, from abroad, not toll-free).
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. UK 03 numbers are different: they're ordinary national-rate lines, as our guide to calling UK 0300 numbers from abroad explains.
