A BSB (Bank State Branch) number is the six-digit code that identifies the bank and branch holding an Australian account, and it's central to how payments and transfers are routed.
A BSB, short for Bank State Branch, is a six-digit code that identifies the specific financial institution and branch where an Australian bank account is held. It works alongside the account number to make sure money reaches the right place. Whenever you set up a direct debit, send a pay-anyone transfer, receive your salary, or arrange a loan repayment, the BSB tells the banking system which institution and branch the payment belongs to. The first two or three digits generally point to the bank, while the remainder identify the branch or processing centre.
Getting the BSB and account number right matters, because an incorrect BSB can delay or misdirect a payment.
