How it works

You may be asked to 'Get NetCode' when you:

  • Register for the CommBank app
  • Authorise certain transactions e.g. pay someone for the first time, update personal info, retrieve log on details, make international money transfers
  • Confirm some online credit and debit card purchases

To complete your transaction:

  • Choose 'Get NetCode'.
  • A 6-digit NetCode will be sent to your mobile as an SMS or app notification. You’ll need to enter that NetCode to finalise your transaction (it’s valid for 2 mins).
  • Once used, delete it.

Check which device is registered

You can check which device you’ve registered for NetCode in the app:

  • Log on to the CommBank app and tap the top left menu
  • Tap Settings and security then Accounts and security
  • Go to Registered devices to see which device you’ve set up

Then, check the following:

  1. You’ve got your mobile data turned on or you’re connected to WiFi. 
  2. You’ve turned on general alerts on your Android or iPhone.

For iOS operating systems: Go to your phone Settings, choose Notifications and find the CommBank app. Tap or slide to turn on. You’ll find NetCode notifications in the app menu (top left of screen) then My notifications. 

Android operating systems: Go to your phone Settings and choose the CommBank app. Tap app menus then Setting and security. Choose Accounts and security then Notifications. Tap or slide to turn on.



Your NetCode will be sent to the number we have on file. If you haven’t received your NetCode by SMS, check we’ve got the right phone number listed:

  • Log on to the CommBank app or NetBank
  • Go to My details
  • Check which mobile number we have on file

If it's changed, update it at your nearest branch or give us a call.

To resend the NetCode, log on to NetBank and start a new request.

Using NetCode overseas

Before you travel

Make sure you do the following to ensure you can receive NetCode while you’re overseas:

  • Take your nominated Australian mobile phone with you
  • Check the device you’re planning to use can receive SMS or has the CommBank app installed with notifications switched on
  • Have global roaming activated on your handset (contact your provider to check)
  • Know the country you’re visiting offers a compatible network

We also suggest you contact your mobile phone service provider prior to travelling as International roaming charges may apply. 

Already overseas

If you’re unable to receive your NetCode because you’re overseas and are using a different phone number or can’t access the app, call us on +61 2 9999 3283 between 6am – 10pm (Australian time).

 If you’d like reverse charges you’ll need to use a land line (not a mobile) to call the international operator of the country you’re in.
