In Australia, every bank account number is preceded by a six-digit number, that is, the BSB number. This number is unique. You can know which branch of that bank through BSB.
The first two digits of this number are the name of the bank, for example, NAB is 08 and ANZ is 0 1. The third digit represents the region, for example, 2 represents NSW, 3 represents Vic, and the last three digits represent bank branches or branches, all of which are HSBCUSTRIAL ALTHAYMarket (Sydney) branches.
His BSB is different from SWIFTCODE, which is a universal number and a global standard. For example, ICBC ICBKCNBJXXX, ICBC representative ICBK, CN is China, BJ is Beijing, plus XXX, it is complete. Icbc Beijing. Of course, China's foreign exchange can be transferred to other branches in the system after going to Beijing.
