Keeping Your Contact Details Current
Maintaining up-to-date contact information is one of the most effective ways to protect your accounts and ensure you receive critical security alerts. Whether you have moved to a new home or changed your mobile phone number, updating your details with NAB promptly helps the bank reach you regarding account activity, fraud alerts, or important service updates.
You can typically manage these updates entirely through your digital banking profile. While most information can be changed online or via the mobile app, certain updates—particularly if you no longer have access to your old registered mobile number—may require a more direct verification process with the bank. Keeping this data accurate ensures that security features like SMS authentication function as intended.

Step-by-Step Guide: Updating Your Details
Managing your profile settings is straightforward within the NAB digital ecosystem. Follow this sequence to update your information.
- Log into the NAB app: Open the app and log in using your credentials.

- Edit contact information: Within the 'My details' section, you can select the fields you wish to update, such as your residential address or mobile number.
- Save your changes: Edit the information as needed, then follow the prompts to confirm and save your new details.
- Verify the update: You may be prompted to authorize the change using an existing security code or authentication method.
Update via Online Banking
To change your address or mobile number, log in to Internet Banking, go to “Profile & Settings”, then “My details”. Update your information, click “Save”, then enter the SMS code sent to your registered number to confirm the change. The update will be applied shortly after.
Update via Mobile App
Open the NAB app and log in. On Android tap “Menu”; on iOS tap “More”. Go to “Profile”, then “My details”. Choose what to change, follow the prompts, and tap “Continue” or “Confirm”. You’ll receive a security code via SMS—enter it to finalize the update.
Troubleshooting Profile Updates
If you experience difficulty updating your information, here is how to resolve common hurdles.
MFA / Login Issues
- Cause: You cannot update your number because you no longer have access to the old mobile phone linked to your account for SMS security codes.
- Simple Fix: If you are still logged in, sometimes push notifications in the NAB app can be used instead of SMS.
- Fallback Action: Contact the bank's customer support line or visit a branch to have a consultant verify your identity and manually update your mobile number.
Browser or App Errors
- Cause: Stored browser cache or an outdated app version can cause profile pages to freeze or fail to display current information.
- Simple Fix: Clear your browser's cookies and cache, or ensure your mobile banking app is updated to the latest version.
- Fallback Action: Switch to a different browser or device, or use the alternate digital portal (app vs. desktop) to complete the update.
Locked Account / ID / Access Issues
- Cause: Repeatedly entering incorrect authentication details can lead to a temporary security lock on your digital profile.
- Simple Fix: Use the 'forgot password' function on the login screen to securely reset your credentials and unlock your profile.
- Fallback Action: If the account remains locked, visit a branch with your photo ID so a teller can manually verify your identity and restore access.
Pro-Tip: Before changing your mobile number, ensure your current registered phone is working and that you can still receive SMS codes. If you wait until you have already switched to a new SIM card without updating your profile first, you may be unable to receive the necessary security codes to authorize the change online, requiring a branch visit to verify your identity.
Frequently Asked Questions
Q: Why can't I update my mobile number online?
If you no longer have access to the mobile number currently registered with the bank, the automated security system cannot send the necessary code to verify that you are the true account holder. This security design protects your account from unauthorized changes. One limitation is that you must prove your identity through other means when this primary authentication method is unavailable. Your practical next step is to call the bank's support number or visit your nearest branch with photo identification.
Q: How long does it take for my address update to be processed?
In most cases, changes made to your contact information through the NAB app or internet banking are applied immediately to your profile. However, if your address change affects a mortgage or a specific investment product, there might be a short internal review period before the change is reflected across all your sub-accounts. One exception is that some legacy paper-based accounts might require additional manual processing. Your practical next step is to log back into your account after 24 hours to confirm the new address is displayed across all your linked products.
