The Bank BSB Number is a 6 digit bank code assigned to Australian banks by Australian Payments Clearing Association (APCA). A BSB Number identifies the financial institution (bank), state and the branch to which a payment item is directed and thus called BSB (Bank-State-Branch). Along with the account number, BSB number is essential for delivering payments through the clearing system. However, note that BSB Numbers with account numbers combinations are used only for domestic transactions in Australia.
Format of BSB Numbers
The 6 digit BSB number is made up of three parts:
AAB-CCC

VIC has the state code of

The last three numbers (CCC) are the unique identifier for a branch. For example,

Thus the BSB Number for St.Kilda South of Westpac Banking Corporation in St Kilda South, VIC is
