BSB Numbers (codes) of banks in Australia

What is a BSB Number?

The BSB number (Bank-State-Branch) is a six-digit numeric code that identifies individual financial institutions and branches within Australia. The BSB code is used in conjunction with the bank account number to identify the recipient account for a money transfer. It’s a lot like a SWIFT code, but used rather for local money transfers as opposed to international money transfers. The BSB identifier is used for processing of paper and electronic transactions, but not in payment card numbering.

The bank state branch number format consists of three parts: AAB-CCC.

The first two digits (AA) specify the bank or financial institution where the money is being sent.
The third digit (B) indicated which state the bank branch is located in.
The last three digits (CCC) are a unique identifier for a branch, usually specifying the address of the bank branch.

Here is an example of a BSB number from Commonwealth Bank of Australia: 062-001.

06 is the two-digit code for Commonwealth Bank of Australia.
The third digit (2) means the branch is located in Australian Capital Territory.
The last three digits (001) mean this is a bank branch in Sydney City.

For paper transactions (cheques) - financial institutions are required to include BSB and bank account numbers on cheques, at the bottom of the cheque to identify the specific bank account number to be debited. Paper transactions refer to Australian Paper Clearing System (APCS).

Electronic transactions - For EFT (Electronic fund transfers) transactions between bank accounts the BSB and bank account numbers must be given for the accounts to be debited as well as for the account to which funds are to be transferred. Electronic transactions are processed under the Bulk Electronic Clearing System (BECS).

International Money Transfers

When you send or receive an international wire with your bank, you might lose money on a bad exchange rate, which is like a hidden fee. That’s because the banks still use an old system to exchange money. We recommend you use Wise, which is usually much cheaper. Wise’s smart technology:
