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.

AAB-CCC
