Losing your phone or suspecting unauthorized access to your bank account can be scary. In moments like this, what you do next really matters. Your UBA account holds your hard-earned money, so knowing how to block it from another phone is important.
Fortunately, UBA has made it easy to take control in urgent situations. Whether you lost your phone, noticed suspicious activity, or your ATM card is missing, you can block your account right away without needing to visit the bank.
Below is everything you need to know to take action fast.
How to Block UBA Account Using USSD Code
UBA offers a simple USSD code you can dial from any phone, even if it’s not the one linked to your account.
To block your UBA account:
- Dial *919*911#
- Follow the prompt to enter the account number you want to block
- Confirm the request
Once completed, your UBA account will be restricted immediately. No one will be able to withdraw or transfer money until you visit a UBA branch to reactivate it. This service is available 24/7 and works on any mobile network in Nigeria.
What if My SIM Card Is Still Active?
If you still have access to your SIM card, it is best to use the USSD code from your own phone to ensure quick verification. However, even from another phone, you can block your UBA account by entering your correct account number when prompted.
