How to Find Your BSB (Bank State Branch) in Australia

A BSB (Bank State Branch) is a 6-digit code identifying your Australian bank branch. Here are the fastest ways to locate yours:

1. Bank Statement (Paper or PDF)

Look at the top—BSB appears next to your account number (format: XXX-XXX or XXXXXX).

2. Online / Mobile Banking

• Log in → Accounts → Select account → Details / Account Info.
• BSB displayed with account number.

3. Contact Your Bank

• Call customer service (13-digit numbers for majors: CBA 13 22 21, Westpac 13 20 32, ANZ 13 13 14, NAB 13 22 65).
• Verify identity (DOB, address, last transaction).

4. Online BSB Lookup Tools

• bsb.com.au, bsblookup.com, bankcodess.com – Search by bank/branch name.
• Bank websites often have "Find BSB" pages.

5. Visit a Branch

Bring photo ID and account details. Staff can print your BSB.

Important Notes

• BSB is branch-specific. If you opened your account at a different branch than you visit, your BSB reflects the opening branch.
• Mergers (e.g., BankWest → CBA, St.George → Westpac) may change BSBs—update payroll, direct debits.
• For international transfers, you need SWIFT/BIC, not BSB.
