If you want to block your GTBank account or unblock your GTBank account, GTBank offers several easy ways to manage your account from your phone. With GTBank’s *737# USSD service, you can transfer money, buy airtime, check account details, and much more. The service is fast, secure, and accessible to everyone.

If you think your GTBank account has been compromised or your phone has been lost, you can block your account immediately. The moment you do that, no transfer or debit transactions will be allowed. You can also unblock your account later using different methods.
