A BSB (Bank-State-Branch) is a six digit number that identifies banks and branches in Australia. Your account number is unique to you and it’s how your account is identified. To make a funds transfer, you’ll need both your recipient’s BSB and account number. Similarly, to receive a transfer, the payer will need your BSB and account number.

Note that you can use the CommBank app to make and receive payments using a mobile number. Find out more about making payments and receiving payments through the app.

  • Log on to NetBank and see your BSB and account number on the ‘My home’ page
