What is a BSB number?
BSB stands for ‘bank, state, branch’, and is a set of 6 characters that identifies where a bank account is in Australia.
Banks use BSB numbers to identify the bank and branch holding an account. Each branch has its own code, though some banks also have a single, centralised BSB for all their accounts.
You’ll need a BSB to send money from one Australian bank account to another, or to send money to an Australian bank account from overseas.

Format of a BSB number
BSB numbers are usually made up of 6 characters. The first 2 characters identify the bank the BSB is associated with (like Commonwealth Bank). The 3rd character is a number between 2 and 7, representing the state the bank branch is located in (4 represents Queensland, for example). The last 3 characters identify the individual branch.
BSB number for international transfers
You can use BSB numbers to send money between Australian accounts, and to send money to an Australian account from overseas. If you’re sending money to Australia from another country, you’ll also need to use a SWIFT code.

BSBs, IBANs, BIC and SWIFT codes — What’s the difference?
You’ll need a few details to send or receive money internationally. Here’s a quick breakdown:
BSB numbers identify bank branches in Australia. You’ll need to use one when sending money to Australia with Wise, along with an account number.
IBANs (international bank account numbers) identify individual bank accounts. They're issued by many banks in Europe, but banks elsewhere in the world are starting to adopt them as well.
SWIFT codes identify banks and financial institutions, but this time for international payments. They're sometimes known as BIC codes.
Where to find your BSB number
You can find the right BSB number to use by searching for your bank on this page. If you’re looking for your own BSB number, you can also find it in your online banking or on your account statements.
Always check the BSB number with your bank or recipient. If you use the wrong number, your payment could bounce, or be sent to the wrong account.
