What is a BSB number and where do I find the BSB number of a CommBank branch?
Last updated 09 December 2016
A BSB (Bank-State-Branch) is a six-digit number that identifies banks and branches across Australia.
Use our locator tool to find the BSB of a specific branch. Just type in the branch location then click on the branch you need the BSB for.
Got the BSB but need the branch details? Type the BSB into our locator tool instead.
You can also see the BSB number for each of your accounts in NetBank.
When you want to transfer money to someone, you’ll need the recipient’s BSB as well as their account number. And you’ll need to give your BSB and account number to anyone transferring money to you.
