Expert Opinion
Calls that reference the Co‑operative Bank’s fraud team often feel official, yet the feedback swings between genuine safety checks and unsettling harassment. Most recipients describe an automated verification asking for birth year, month, last four digits and transaction amount – a typical anti‑fraud protocol. When the call is recognised as a bank number, answering can confirm a legitimate large payment, but the same script is also used by scammers to harvest details. If you’re unsure, hang up, then log into your online banking to verify any pending alerts. Never disclose full PINs or passwords over the phone, and report suspicious numbers to your bank’s fraud desk.
