How to Block GTBank ATM Card

The fastest way to block your account from transactions is to contact your account manager or customer service to place a bar on your account from transacting. However, if this happens off the working-hour then there is a quick way to keep your account safe and render your ATM card useless if taken at gunpoint or misplaced.

There are several ways to block your GTbank ATM card. You can block online, using social media, with GTbank USSD code and GTbank internet banking application. However, the downside of blocking your ATM GTbank card is that there is no direct USSD code to block your ATM card on another phone unless you put a call through to the GTbank customer service.

You also want to beware of scammers when you want to block your GTbank card. Currently, GTbank does not have the means to block cards by SMS.
