If you are a Guaranty Trust Bank customer, you should be conversant with the GTBank's 737 shortcode service as it allows customers to perform a different kind of transaction like recharging your phone, check balance, transfer funds, paying your bills, opening an account and much more.
Transactions using the code 737 take less than a minute to conclude and it can be done at the comfort of your home, by just using the last four (4) digits of his ATM card.
Using just the last 4 digits of your ATM card isn't secure enough because anyone who steals your phone and wallet (where your bank card is likely to be) can use the service to clear off all your hard-earned.
I'm glad to inform you that GTBank has made the service more secure. The service now requires a 4-digit PIN to be able to complete transactions on the platform. That is certainly a more secure approach to the service than the previous use of your ATM card’s last 4 digits.
To Create A Pin ON GTBank's 737 Service
According to the instructions on GTBank’s website, here is how to create a PIN on the 737 platform:
1. Dial *737*5# on the phone number that is linked to your account.
2. Input the last 6 digits of your ATM debit card
3. Create your 4-digit PIN
You will be asked for your 4-digit PIN to complete any transactions on the service, so do not forget it.
