Keeping Your NAB Cards Secure
Protecting your NAB cards and personal information is a shared responsibility. While the bank employs advanced security monitoring to detect unauthorised activity, being proactive helps safeguard your accounts. This includes managing your card access through the NAB app, remaining vigilant against unsolicited communications, and securing your personal identification data.
If you suspect that your card has been lost, stolen, or compromised, taking quick action is the most effective way to limit potential financial loss. Knowing the tools available in your digital banking profile and the correct channels to report suspicious activity empowers you to respond effectively should an incident occur.

Step-by-Step Guide: Locking and Reporting
Taking immediate action when you notice a card issue is vital. Follow these steps to secure your accounts.
- Lock the card: If you misplace your card or notice an unfamiliar transaction, log into the NAB app, select 'Cards', tap the relevant card, and toggle the 'Block card' or 'Lock card' feature.
- Review activity: Check your transaction history in the app or internet banking to identify any unauthorised charges.
- Report the incident: If the card is permanently lost, stolen, or unauthorised transactions have occurred, call the 24/7 fraud team immediately at 13 22 65.
- Update details: If your card was compromised, change your online banking password and enable multi-factor authentication (MFA) on your accounts.
- Monitor for alerts: Keep an eye on your account notifications; the bank may send SMS or push notifications asking you to confirm legitimate transactions.
Troubleshooting Account and Access Issues
Technical hurdles can occasionally complicate your response to a security concern. Here is how to handle them.
MFA / Login Issues
- Cause: Verification codes may be delayed due to network issues or an outdated mobile number on file.
- Simple Fix: Ensure your device has a clear signal and restart it to refresh your network connection before requesting a new code.
- Fallback Action: If you cannot receive a code, call 13 22 65 to verify your identity verbally with a consultant.
Browser or App Errors
- Cause: Outdated app versions or corrupted cache data can cause the 'block card' functionality to fail.
- Simple Fix: Update the NAB app via your device's app store or clear your mobile app cache.
- Fallback Action: Access your account through a web browser on a secure device or call the bank to have the card blocked manually.
Locked Account / ID / Access Issues
- Cause: Entering incorrect login details repeatedly can trigger a security lock to prevent unauthorised entry.
- Simple Fix: Use the 'Forgot Password' link on the login page to reset your access securely.
- Fallback Action: Visit a local branch with photo ID or call support to have your profile unlocked.
Pro-Tip: Enable push notifications in the NAB app for all transactions. Getting a notification the moment a purchase is made allows you to spot and report fraudulent activity before it escalates, providing an extra layer of real-time security.
Frequently Asked Questions
Q: What should I do if I receive a suspicious SMS asking me to click a link?
NAB will never send you a link in an unexpected SMS asking you to log in to internet banking or share personal details. Criminals use "spoofing" to make these messages appear legitimate. One exception is if you are expecting a security notification you initiated. Your practical next step is to forward the suspicious SMS to 0476 220 003, then delete the message without clicking anything.
Q: How does the bank verify a suspicious transaction?
If the system flags activity as unusual, it will typically send a push notification to your app or an SMS to your mobile phone asking you to confirm if the transaction was yours. If you select "No," the card is automatically blocked. One limitation is that this system relies on your mobile number being correct. Your practical next step is to ensure your contact details are updated in your banking profile and respond to these security alerts immediately if you receive one.
