Australia Bank State Branch (BSB)



What is BSB?

A Bank State Branch (BSB) number is a numerical code that identifies an individual branch of a financial institution within Australia. This six digit number plus your account number is what we use to identify your account.

In Australia, BSB codes are allocated by the Australian Payments Clearing Association (APCA). BSB codes are used in a number of payment systems in Australia. To access the various clearance systems a financial institution must have its own BSB or use an intermediary with a BSB.


Format



The BSB is a six-digit code e.g. AAB-CCC. The format is as follows.

  • The first two digits (AA) specify the financial institution / bank.
  • The third digit (B) indicates the state where the branch is located.
  • The last three digits (CCC) are the unique identifier for a branch..

Therefore, the BSB number for the Westpac Bank in Belconnen, Australian Capital Territory (ACT) (which has the identifying number 732), would be 032-732

  • AA = 03 (Westpac Banking Corporation)
  • B = 2 (ACT)
  • CCC = 732 (Belconnen)
