How BSB works
The first two digits identify the bank, the third digit identifies the state, and the last three identify the specific branch. BSB numbers are administered by the Australian Payments Network.

Good to know
The state digit maps to: 2 = NSW, 3 = VIC, 4 = QLD, 5 = SA, 6 = WA, 7 = TAS.
PayID transfers use your email or phone instead of BSB — but BSB is still required for direct debits.
Online-only banks like ING and Up use a single BSB for all customers.
