This tool validates BSB format and identifies the bank from the prefix. For the full branch directory, refer to the Australian Payments Network.
What BSB validation does not tell you
BSB validation confirms the bank and branch. That is a useful first step, but it leaves the most important question unanswered.
Who owns the account
A valid BSB says nothing about who controls the account linked to it.
Whether it's active
The BSB could be valid but the account may be closed or frozen.
Whether it's your supplier
Scammers use real BSBs with their own accounts. The BSB will validate fine.
For complete bank account verification, you need Confirmation of Payee
Confirmation of Payee checks the account holder's name against the person or business you intend to pay. It answers the question BSB validation cannot: does this account belong to who you think it does?
How BSB numbers work
BSB stands for Bank-State-Branch. It is a six-digit code used in Australia to identify the financial institution and branch for a bank account. Every Australian bank account has a BSB paired with an account number.
The first two or three digits identify the bank. For example, BSBs starting with 062 belong to the Commonwealth Bank, while 032 indicates Westpac. The remaining digits identify the specific branch location.
BSB numbers are managed by the Australian Payments Network (AusPayNet) and are used for direct credit, direct debit, and BPAY transactions. When you set up a payment, the BSB routes the funds to the correct bank and branch.
