How scams that copy lenders and credit cards work
Lenders and card companies are copied in the same way as banks. UK Finance says callers claim there has been fraud on your account and ask you to move money to a "safe account" that the criminal controls.
Call the lender back on the number on your card, statement or its own website, or call 159 if your bank or card provider is part of it.
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 Capital One UK back on the number on the back of your card, or call 159, which connects you to your bank.
Safe ways to check
- Call 159 (opens in a new tab): Stop Scams UK runs 159, which connects you to your bank. It cannot be spoofed.
- Capital One UK's own contact page (opens in a new tab): Where this number is published.
- Report Fraud (opens in a new tab): Report fraud and cyber crime in England, Wales and Northern Ireland. In Scotland, call Police Scotland on 101.
- Forward scam texts to 7726 (opens in a new tab): It is free, and reports the message to your mobile provider.
- How number spoofing works: Why a genuine number on your screen does not prove who is calling.
