If you are a Guaranty Trust Bank customer, the code *737# won't be new to you. We all know how easy it is to operate GTBank's 737 shortcode service. You can buy Airtime, Check balance, make a transfer etc using this short code service. It only requires for the last 4 digits on your ATM card before processing any transaction. The 4digits is just a PIN to process your transactions.
 
But now, GTBank has made the service even more secured. Using just the last 4 digits on your ATM card isn't secured at all; because anyone who steals your phone and wallet (where your bank card is likely to be) can use the service lol



Well, GTBank has looked into this and now made it more secured. The service now requires a 4-digit PIN to be able to complete transactions on the service. That is certainly a more secure approach to the service than the previous use of your card’s last 4 digits. It is a surprise that it took 11 months, but better late than never.

HOW TO CREATE A PIN ON GTBANK'S 737 SERVICE

According to the instructions on GTBank’s website, here is how to create a PIN for use on the 737 platform:

Dial *737*5# on the phone number that is linked to your account.
Input the last 6 digits of your ATM debit card
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.
