How To Link NIN/BVN To GTbank Account Quickly

Last Updated on Mar 23rd, 2024

Do you know you can link your NIN/BVN to your GTbank account by yourself?

NIN stands for National Identification Number while BVN means Bank Verification Number. Both of these are important in Nigeria.

Your NIN is your ID number for the government while your BVN helps banks protect your account.

If you fail to link your National Identification Number (NIN) and Bank Verification Number (BVN) to your GTBank account before April 2024, the Central Bank of Nigeria (CBN) has announced that accounts will be frozen starting from this date​​.

So, let me teach you how to link your BVN/NIN to your GTbank account.

Here are 3 ways to link your NIN and BVN to your GTbank account:

1. USSD code

To link your BVN, dial *737*20*BVN# from the phone number linked to your GTBank account. This will link your BVN easily. Currently, there is no USSD code to link your NIN. You can try the other two options below.

2. GTbank website

  1. Visit GTBank’s self-service portal at

Approach the customer service desk, and they will guide you through the process of linking your NIN to your account.

Issues That Might Arise During Linking of BVN/NIN

1. Incorrect NIN number

If you enter an incorrect NIN, the system will not be able to match your identity, leading to a failed linking attempt.

Double-check your NIN before submitting it to ensure accuracy. If you continue to face issues, contact GTBank customer care for assistance.

2. Technical difficulties

Sometimes, technical glitches, like network problems or maintenance, can interrupt linking.

If you encounter any technical difficulties, try the process again after some time. If the issue persists, reach out to GTBank customer care for help.

3. Mismatched information

The information on your GTBank account must match the details associated with your NIN and BVN. If there’s a discrepancy (e.g., different names or phone numbers), the linking might fail.

Make sure all your records are consistent. Update any old information with the bank or the National Identity Management Commission (NIMC) as needed.

4. USSD code not working

The USSD code for linking may not work. This could be due to issues with your mobile network or because you’re dialing from a phone number that’s not linked to your GTBank account.

Make sure you’re using the correct phone number and USSD code. If problems continue, consider using another linking method or contacting customer support.

3. Website login issues

You might have trouble logging into GTBank’s internet banking to link your NIN. This can be due to forgotten login details or website problems.

If you can’t log in, follow the website’s instructions for getting back or resetting your credentials. Or, use a different method for linking your NIN/BVN.
