Few months back, Guarantee Trust Bank, which is one of the leading financial institutions in Nigeria came up with an airtime recharge system that lets you easily recharge the very phone number used in your opening of your account simply by dialing some sets of codes of which I covered in this guide.

This time out, GTBank decided to take things a little further by enabling her customers recharge other unregistered phone numbers using an account owners phone.

GTbank Recharge

Let’s say you own an MTN and a Glo line of which the MTN was used in your GTB account reregistration, you can now recharge the Glo line using the MTN simply by dialing the codes below.

Dial *737*Amount*Other Phone Number#

That means, you’ll dial *737*1000*08051234567# if you wish to recharge 08051234567 with N1000.

Note: The code must be dialed from a phone number that is registered with an existing GTBank account.  And make sure the account has an amount more than you are trying to recharge.

That’s GTB making life easier for her customers. BTW, what are you waiting for? Get down with your phones and top me up with airtime. 🙂


  1. I really love this concept from Gtb, the only problem i have with gtb is their workers, some of them could be rude sometimes

  2. I’ve been trying to top-up my wife’s line and was asked to input the last four digits on my atm card.but there are no numbers on the back of the.just 3figures and I got an incorrect reply.how do I go about this

  3. I want to change my alert number to another number because I misplaced my phone. How Can I do this please? Gtbank doesn’t work in ado ekiti anymore would have gone to bank to change it. Please tell me what to do. Thanks
