GTBank USSD Code Activation Fees

• USSD Activation Fee: 6.98 Naira

Registering the USSD code on a mobile phone costs money. But the cost you bear is not from GTBank but from your mobile network in Nigeria (Airtel, Mtn, Glo or 9 mobile)

When you dial the GTBank USSD activation code, your phone network will charge you 6.98 Naira.

The money will be deducted from your airtime balance, not your bank account. 

Since this is a standard fee across these networks, you must have sufficient airtime before dialling the GTB code. 

Without this, *737# will not work for your banking needs.

Why is GTB Bank USSD Code not Working?

Is the GTBank USSD code not working on your phone? Here are the reasons: 

• Dialling the code from the wrong phone
• Entering the wrong code or PIN
• Having insufficient airtime on the phone
• Experiencing bank and mobile network issues

Now, here is the right way to resolve these issues

The GTB code will not work if you want to activate it on a phone not linked to your bank account.

Not even from your second phone number talkless of someone else’s smartphone.

Solution: Activate the code on the GTBank registered phone number. But if you have lost the phone, visit the GTBank branch to update the number to a new one.

2. Wrong USSD Code

The GTBank USSD code is not working because you enter the wrong USSD code or PIN. You can get an error like ‘authentication failed‘.

Solution: Confirm you enter the right GTBank short USSD code. If in doubt, dial *737# and follow the activation instructions.

2. Insufficient Airtime

Most times, having insufficient airtime is why the GTB USSD code is not working on a phone.

Solution: Recharge your phone number and retry the code to activate it.

3. Network issue

The network can be the reason why GTBank *737# is not working. When the network of GTBank or the mobile operator is down, it affects USSD banking.
