How to Deactivate your FAB Debit Card? Detailed Guide 2026
Lost your card, spotted a transaction you did not make, or simply want to stop using it? Wondering how to deactivate your FAB debit card? You can freeze or block it in seconds in the FAB Mobile app, through online banking, by calling FAB or at a branch. This guide explains each method and what to do next.
Deactivate your FAB Debit Card Via Mobile app
The FAB Mobile app is the fastest way. It works 24/7 and the block takes effect immediately:
Step # 1: First of all, open the FAB mobile application (if you have not installed it already, install it through the Play Store for Android and the Apple App Store for iOS devices)
Step # 2: Log in with your username and password. If you are a new user, register first using your card details.
Step # 3: Tap Cards and select the debit card you want to stop.
Step # 4: Tap Freeze card to pause it temporarily, or Block & Replace to block it permanently and order a new card. Confirm your choice.
Note: If you only misplaced the card, freeze it instead of blocking it. You can unfreeze it in the app as soon as you find it, and you keep the same card number.

No. Freezing or blocking your FAB debit card is free, whether you do it in the app, online or at a branch.

No. Blocking or freezing only affects the card. Your account stays open and you can still use the app and online banking.
