How scams that copy banks and building societies work

UK Finance describes the usual pattern: a caller says they are from your bank or the police, tells you there has been fraud on your account, and asks you to move your money to a "safe account". The criminal controls that account.

Stop Scams UK runs 159, which puts you through to your bank and cannot be spoofed. Hang up and call 159 or the number on the back of your card.

This could still be a scam call

Criminals can make their number look like a genuine one (this is called spoofing). If someone calls from this number and asks for money, bank details, a code or passwords, hang up. Then call Nationwide Building Society back on the number on the back of your card, or call 159, which connects you to your bank.
