Seeing this number on your screen does not prove the bank is calling.
Scammers fake banks' official numbers (spoofing). A bank never asks for a BLIK code, password, PIN or text-message code, never asks you to install an app and never tells you to move money to a “safe account”. Hang up and call the number on this page, on your card or in your banking app yourself.

A mobile number may have been moved to another network and kept its prefix. The original operator is the company that the Polish regulator (UKE) assigned the number block to (register of 23 October 2026). It does not have to be the number's network today or the brand the subscriber uses.
