In Australia, the Australian Payments Network (AusPayNet) is now the regulatory body of cheque clearances and of the BSB codes in Australia. AusPayNet assigns the bank code to a financial institution and the financial institution allocates the other digits to its branches, in line with guidelines set by AusPayNet. Some financial institutions have more than one bank identifier, arising from mergers of financial institutions or consolidating by banks of their trading and savings banks operations. As of March 2012, almost 14,300 unique BSB code values were in use.
