About BSB Lookup

BSB Lookup is a free online tool designed to help Australians quickly search, check and verify BSB numbers for any bank branch across the country.

Our Mission

We believe that banking information should be easy to find and free to access. Our goal is to provide the most accurate and up-to-date BSB directory available, so you can make bank transfers with confidence.

Data Source

Our BSB database is sourced from the Australian Payments Network (AusPayNet), the official body that manages BSB allocations for all Australian financial institutions. We update our records monthly to reflect the latest changes, including new branches, closures and bank mergers.

What You Can Do

• Search BSB numbers by code, bank name, branch or suburb
• Browse BSB directories by bank or state
• Verify BSB details before making a payment
• Learn about BSB number format and structure
