How to Change Your Bank Account Phone Number

Changing the phone number linked to your bank account may be necessary if you have lost your old SIM, changed your mobile number, or want to update your banking information. The exact procedure depends on your bank and the services available to you.

How to Change Your Bank Account Phone Number

The safest way to change your registered phone number is to use your bank’s official channel. Some banks may allow certain profile updates through their mobile app, while others require you to visit a branch for verification.

Contact Your Bank First

If you still have access to your old number, contact your bank through its official customer-service channel and ask about changing the registered phone number. The bank will explain whether the update can be completed remotely or requires a branch visit.

Visit Your Bank Branch

If your old SIM has been lost, stolen, or permanently deactivated, visiting a branch may be necessary. Take a valid means of identification and provide your account details and new phone number. The bank will verify your identity before updating the record.

What You May Need

• Your bank account details.
• A valid means of identification.
• Your current or previous phone number, where available.
• The new phone number you want to register.
• Any additional verification requested by your bank.

Can You Change Your Number Through a Bank App?

Some banks provide options for managing personal information through their mobile banking platforms, but not every bank allows customers to change their registered phone number entirely online. Check your bank’s current instructions before attempting the update.

What If Your Old Phone Number Is Lost?

If you no longer have access to your old number, inform your bank immediately. You should also contact your mobile network provider about recovering or replacing the SIM if possible, particularly if the number is still connected to your banking services.

Why Your Registered Phone Number Matters

Your registered number may be used for transaction notifications, account verification, USSD banking, and other security-related services. Keeping it updated helps ensure that important banking communications reach you.

After Changing Your Phone Number

Confirm that the new number has been successfully linked to your account. Check that banking alerts and other services associated with the number are working correctly. If you use USSD banking, follow your bank’s instructions for ensuring the service is connected to the updated number.

Security Tips

Only provide your new phone number through your bank’s official channels. Never give your OTP, PIN, password, or other confidential banking credentials to someone claiming they need them to update your number.
