Last updated 12 June 2015

A BSB (Bank-State-Branch) is a 6-digit number that identifies banks and branches in Australia. Your account number is unique to you, and how your account is identified. Your account number follows your BSB. 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.

If you are a Commonwealth Bank customer, there are a few ways to find your BSB and account number:

  • The bank will have notified you of both your BSB and account number after you opened your account
  • Log in to NetBank and you can find your BSB and account number within the 'My home' page
  • Use our locator tool to search for the branch, select a branch in the map to find the BSB number; or
  • Visit any Commonwealth Bank branch.
