USAGE RULES

When field 57a is not present, it means that the Receiver is also the debtor's bank

Option A is the preferred option.

If the debtor's bank cannot be identified by a financial institution BIC, option C should be used containing a 2!a clearing system code preceded by a double '//'.

Option D must only be used in exceptional circumstances: when the party cannot be identified by a financial institution BIC, when there is a need to be able to specify a name and address, for example, due to regulatory considerations or when there is a bilateral agreement between the Sender and the Receiver permitting its use.

When qualified by a clearing system code or an account number, the use of option D will enable the automated processing of the instruction(s) by the Receiver.
