Your mobile banking PIN (different from your card PIN!) is the 4-6 digit code you use to log into the NAB app. If you want to change it for security or because you forgot it, here’s exactly how to do it.
⚠️ Important:
- Changing your mobile banking PIN won’t affect your card PIN or contactless payments.
- NAB will never call/SMS asking for your PIN.
📱 Method 1: Change PIN in the NAB App (Fastest & Easiest)
Use this if you can still log into the app with your current PIN.
- Open the NAB app on your phone
→ Log in with your current PIN or biometrics (Face ID/fingerprint). - Tap “Profile” (bottom right corner)
→ Look for the person icon. - Select “Security”
→ Scroll to find this option. - Tap “Change Mobile PIN”
→ You may need to re-enter your current PIN for security. - Create a new PIN
→ Enter a 4-6 digit code (e.g.,4729
).
→ Do NOT use:
– Your birthday (1708
)
– Simple sequences (1111
,1234
)
– Your card PIN (keep them different!). - Confirm your new PIN
→ Type it again exactly. - Tap “Save”
→ You’ll see: “Your mobile PIN has been updated”.
Done! Use your new PIN next time you log in.

📞 Method 2: Reset PIN by Phone (If You’re Locked Out)
Use this if you forgot your PIN and can’t log in.
- Call NAB’s 24/7 Support:
→ Dial 13 22 65 in Australia.
→ Overseas? Dial +61 3 8641 9083. - Say:
“I need to reset my NAB mobile banking PIN.” - Verify your identity:
→ Provide:
– Your full name and date of birth
– NAB client number or card number
– Answer security questions (e.g., recent transactions) - Get a temporary PIN:
→ The agent will give you a one-time temporary PIN. - Log into the app:
→ Open NAB app → Enter the temporary PIN.
→ Immediately set a new PIN (Steps 2-7 in Method 1).
🏦 Method 3: Reset at a NAB Branch (In-Person Help)
Use this if phone support didn’t work or you prefer face-to-face.
Bring with you:
- Photo ID (Australian driver’s licence or passport).
- NAB debit/credit card (if you have one).
What to do:
- Find your nearest branch: NAB Branch Locator.
- Tell the staff:
“I need to reset my mobile banking PIN for the app.” - Verify your identity (they’ll scan your ID).
- Staff will help you:
- Set a new PIN on the spot.
- Or guide you through resetting it via the app.
Time needed: ≈ 10 minutes.
🛠️ Troubleshooting: Common Problems

App crashes after PIN change | Update app → Restart phone → Uninstall/reinstall NAB app. |

🔒 Keep Your PIN Secure: Best Practices
✅ Do This:
- Change your PIN every 6 months.
- Use a random number (e.g., childhood friend’s house number).
- Enable biometric login (Face ID/fingerprint) to skip typing PIN.
- Memorize it – never save it in your phone notes.
❌ Avoid This:
- Sharing your PIN with anyone (even family).
- Using the same PIN for banking and your phone unlock.
- Obvious numbers like
0000
or2580
(straight line on keypad).
💡 Pro Tip: Set a calendar reminder for PIN changes! Label it “NAB Security Check”.
Can I use letters or symbols in my NAB mobile PIN?
No. It must be 4-6 digits only (numbers 0-9).
Will changing my PIN log me out of other devices?
Yes. After changing it, you’ll need to enter the new PIN on all devices using the NAB app.
What if I forget my new PIN again?
Repeat the steps above! Call 13 22 65 or visit a branch.
Can I change my PIN online via a browser?
No. You can only change your mobile banking PIN in the NAB app or with help from NAB (phone/branch).
Is there a fee to reset my PIN?
Never. PIN resets are free through all methods.
✅ Done! You’re in Control.
Changing your NAB mobile banking PIN takes under 3 minutes in the app. Remember:
- Use a unique number you haven’t used elsewhere.
- Never share it – not even with NAB staff (they’ll never ask).
- Stuck? Call 13 22 65 – they’re available 24/7.
🔐 Security Alert: If you didn’t change your PIN but get a “PIN updated” message, call NAB immediately – it could be fraud.
