With the rate at which the internet banking system is becoming the system to use for all banking transactions, it also seems like the right time for internet hackers to focus on this area and gain access to anyone’s finances.

Instead of waiting for that time to come, why don’t you prevent any of that from happening? As a GTBank user/customer, you can now lock your bank account just in case something happens to you e.g misplacing your phone, misplacing the SIM card that is linked to your GTBank account, etc.  GTBank has made this easy for all of their customers to do using their USSD code, *737#.


Dial *737*51*74# on the SIM card you use for your GTBank banking transactions. After dialing the code, you will be required to provide the phone number registered to your account and your 737 PIN. Once your account is locked, nobody will be able to make any transfers from your account, and all debit transactions will be blocked. To unlock your account, call GTConnect, contact the care center or visit any GTBank branch near you.
