Why SMS Security Matters
SMS security is a vital feature of NAB’s internet banking, providing an extra layer of protection for your account. By sending a one-time security code (often called an OTP or one-time passcode) to your registered mobile number, the bank ensures that sensitive transactions—such as transferring money to new payees, resetting passwords, or adding new credit cards to digital wallets—are authorized by you. This process helps significantly reduce the risk of unauthorized access to your funds.
Registering for this feature is a straightforward process managed entirely through your internet banking profile. Once registered, the system will automatically prompt you to enter the code received via SMS whenever you perform a high-risk transaction or manage security-sensitive settings. Keeping your mobile number current in your bank profile is the most important step to ensuring this security feature functions without interruption.

Troubleshooting SMS Security
If you face difficulty during registration or when trying to receive codes, try these common fixes.
MFA / Login Issues
- Cause: The most common cause for not receiving a code is that your registered mobile number is outdated or incorrect in the bank's system.
- Simple Fix: Check your current profile settings to verify that the mobile number listed matches the one you are currently using.
- Fallback Action: Call NAB support on 13 22 65 to have a representative verify your identity and update your mobile details.
Browser or App Errors
- Cause: An outdated browser cache or connection errors can sometimes prevent the registration page from processing your request.
- Simple Fix: Clear your browser's cookies and cache, or try accessing Internet Banking via a different web browser.
- Fallback Action: Use a desktop browser instead of a mobile browser, as desktops provide a more stable environment for security settings.
Locked Account / ID / Access Issues
- Cause: Repeatedly entering incorrect SMS codes during registration will trigger a temporary security lockout for your own protection.
- Simple Fix: Wait for the temporary lockout period to pass (usually a few hours) before attempting registration again.
- Fallback Action: If you remain locked out, visit a local NAB branch with your photo identification to restore access.
Pro-Tip: If you travel internationally, ensure you have international roaming enabled on your phone before you leave Australia. Without an active connection to an overseas mobile network, you will not receive SMS security codes, which could leave you unable to perform essential banking transactions while abroad.
Frequently Asked Questions
Q: What should I do if I don't receive my SMS code?
If you don't receive a security code, first verify that your phone has a strong signal and that you are not in an area with restricted reception. The system relies on standard network delivery, which can sometimes be delayed by local telecommunications congestion. One limitation is that you must have a phone number registered with the bank; you cannot use a number that hasn't been verified in your profile. Your practical next step is to wait a few minutes, ensure your phone is on, and then select the 'Resend code' option on the screen.
Q: Is it possible to use a home or work phone for SMS security?
SMS security codes are specifically designed for mobile devices capable of receiving standard text messages. While the system requires a mobile number for SMS, you must ensure that this number is the one you personally use and have control over. One edge case is that some older VoIP-based or landline services cannot receive text messages, which will cause the registration to fail. Your practical next step is to ensure you are registering a personal mobile number that has active SMS capability.
