This guide simplifies the process for you. By the end of this post, you’ll learn:

• How to use the GTBank USSD code to block your ATM card from any phone.

Steps to Block GTBank ATM Card Using USSD on Another Phone

Blocking your GTBank ATM card using USSD can easily be done from any phone not linked to your GTB account. Follow the steps below:

1. Dial the USSD Code

Start by dialling *737*51*10# from another phone. That is, the mobile number not registered with your GTBank account but with another customer’s account.

This code is the gateway to initiating the card blocking process from any phone in Nigeria. Ensure that you have access to this phone and sufficient network coverage.

2. Enter Your Account Number

After dialling the code, you will be prompted to input your 10-digit GTBank account number linked to the ATM card you want to block. Double-check the number for accuracy to avoid errors.

3. Confirm Blocking Request

You’ll see a confirmation screen asking you to verify your account number. Press 1 to confirm. Next, you’ll be prompted to enter your USSD PIN. Once you input the correct PIN, your GTBank ATM card will be blocked immediately.

This process ensures that no unauthorized transactions can occur on the blocked card.
