About BSBNumber.com.au
BSBNumber.com.au is a free, independent BSB (Bank State Branch) lookup service built for Australians who need fast, accurate bank routing information.

Our Data Source: AusPayNet
Every BSB record on this website is sourced from AusPayNet — the independent industry body that governs Australia's payment infrastructure and maintains the official national BSB directory.
AusPayNet is the authoritative source for BSB data in Australia. Financial institutions, payment processors, and enterprise software providers rely on the same dataset we use. We do not generate, estimate, or infer BSB records. Every entry in our database originates from the official AusPayNet directory.
We publish a monthly update log every time AusPayNet releases a new directory revision, documenting every addition, change, and deletion across Australia's banking network. You can review all historical updates in our BSB Update Archive.

What Is a BSB Number?
A BSB (Bank State Branch) number is a six-digit code used in Australia to identify the bank and branch associated with a bank account. It is required for:
• Domestic bank transfers (EFT, direct debit, payroll)
• Setting up a new payee in your banking app
• Receiving payments from employers or clients
• International wire transfers (combined with your account number and SWIFT code)
The first two digits identify the bank; the remaining digits identify the specific branch or processing centre. With the rise of digital-only banks and neobanks, BSB codes are increasingly assigned to centralised digital branches rather than physical locations — making reliable verification tools like ours more important than ever.

Why BSB Accuracy Matters
An incorrect BSB number can cause:
• Payment delays — the transfer bounces back or is held for manual review
• Failed payroll — employees or contractors don't receive funds on time
• Misdirected payments — in rare cases, funds may reach the wrong institution
• Fraud risk — scammers sometimes provide altered BSB or account numbers to intercept payments (known as Business Email Compromise or invoice fraud)
Verifying BSB details through an up-to-date, authoritative source is a simple step that protects both individuals and businesses. It takes seconds and can prevent costly errors.

A Note on Digital Bank BSB Codes
Traditional BSB codes were designed around physical branches, with the third digit historically indicating the state. This convention no longer applies to many modern BSB codes.
Neobanks, digital banking divisions, and fintech providers are often assigned BSB codes that do not follow historical state-based patterns. For example, ANZ Plus uses BSB 014-111 — registered in Victoria despite the "4" traditionally indicating Queensland. This causes frequent confusion and unnecessary fraud concerns.
Our website includes in-depth guides explaining these non-standard BSB codes, helping users confidently verify payment details without misinformation.
───
Our Commitment to Accuracy
We take data accuracy seriously. Our commitments:
• Monthly synchronisation with the AusPayNet official directory
• No manual data entry — all records are imported directly from the source
• Public update logs — every monthly change is documented and published
• Error reporting — if you spot a discrepancy, you can report it to us and we will investigate promptly
We cannot guarantee real-time accuracy between AusPayNet release cycles, as banks occasionally make changes outside of the monthly schedule. For time-sensitive or high-value transactions, we always recommend confirming details directly with the receiving bank.
