A BSB (Bank-State-Branch) number is a six-digit code that identifies a bank and branch in Australia. It is written as two groups of three, such as 123-456, and is used with an account number to send money within Australia.

PayID: an alternative

Australia's New Payments Platform lets people register a PayID, such as a phone number or email, linked to their account. Payers can then send money to the PayID instead of typing a BSB and account number.

Paying from abroad

Australia does not use IBANs. To send money there from another country, the sender's bank usually asks for the receiving bank's SWIFT code, plus the BSB and account number.
