Why Updating Your Number Matters
Your registered phone number acts as a primary security key for your banking profile. Financial providers use this number to send authorization codes when you log in on a new device, set up a new payee, or make online purchases. Keeping these contact details up to date ensures you retain full access to your funds and prevents sensitive alerts from going to an old device.
If you are switching mobile networks or replacing a lost phone, you will need to inform the bank so they can route these security messages correctly. You can typically handle this update through digital channels, provided you still have access to your previous number, or by visiting a branch if you are completely locked out.

Step-by-Step Guide to Updating Your Number
For most customers, the quickest route is using the digital banking portal. Start by logging into your Metro Bank mobile app or the secure internet banking site using your current credentials.
Navigate to the personal details or account settings section, which is typically found in the main menu or by tapping your profile icon. Look for the specific section labeled "Contact Details" or "Phone Numbers."
Select the option to edit your mobile number and type in your new digits. At this stage, the bank's system usually sends a One-Time Passcode (OTP) to your old phone number to confirm that the real account holder is making the change.
Enter the security code to verify the update. Once confirmed, the system will replace your old number. It is generally a good idea to log out and log back in to ensure the new details have synced across the banking network.
Troubleshooting Common Issues
MFA or Login Issues
Cause: You cannot receive the authorization text message required to approve the update because you have already lost your old phone or deactivated the old SIM card.
Fix: If you use a biometric login (like Face ID) on a trusted device, check if the app allows you to authorize the change using your biometrics instead of an SMS code.
Fallback Action: Take your debit card and a valid photographic ID to a Metro Bank branch. The counter staff can bypass the SMS requirement and manually update your profile.
Browser or App Errors
Cause: The app might freeze or return a connection error when you attempt to save the new number due to cached data conflicts or poor network reception.
Fix: Connect to a stable Wi-Fi network, force close the banking app, clear your device's application cache, and restart the process.
Fallback Action: Bypass the mobile application entirely and log into your internet banking portal via a desktop web browser to update your profile.
Locked Account or Access Issues
Cause: Attempting to enter the SMS security code incorrectly multiple times will trigger an automated security block, locking your digital profile to prevent unauthorized changes.
Fix: Use the "Forgotten login details" link on the app's home screen to safely reset your security credentials using your account recovery information.
Fallback Action: Call the Metro Bank customer service team. Once you answer standard security questions, an agent can lift the block and help process the number change over the phone.
Pro-Tip: If you are planning to change your mobile provider, update your phone number in the Metro Bank app while your old SIM card is still active in your device. This ensures you can seamlessly receive the mandatory security text needed to approve the switch, saving you a trip to a physical branch.
Frequently Asked Questions
Why can't I update my number through the app right now?
You might log in intending to change your details but find the edit option grayed out or restricted. The banking system occasionally limits digital profile changes if it detects unusual login activity, such as accessing the app from a new country or an unrecognized device, to protect against account takeovers. When this happens, the automated system restricts self-service updates temporarily. Wait until you are back on your usual home Wi-Fi network, or call customer support to verify your identity and process the change securely.
How long does it take for my new number to work for online purchases?
After you successfully update your number, you might try to buy something online and notice the security code is still trying to send to the old phone. While the bank's internal database updates quite quickly, third-party payment networks (like Visa or Mastercard's 3D Secure systems) can sometimes take a few hours to synchronize the new contact data. If an online payment verification fails right after you update your profile, wait a few hours for the networks to align, and then retry the transaction.
Can I change the phone number for my partner on our joint account?
Handling administrative tasks for a shared household is common, but banking systems treat contact details on a strictly individual basis. Even if you hold a joint current account together, Metro Bank maintains separate digital profiles and login credentials for each person. You cannot log into your app and change the phone number associated with your partner's profile. They will need to log into their own app or call the bank themselves to update their specific contact information.
