IBAN stands for International Bank Account Number. It is a standard developed by ISO (International Organization for Standardization) and the ECBS (European Committee for Banking Standards) for the presentation of bank identification systems and account numbers, for which switzerland plays a significant role. Ever since 2001 switzerland was processing payment transactions quoted in IBAN format.

The main purpose of an IBAN is to promote straight-through processing of international financial transactions, thereby making the transfer of funds between different EU countries quick, fast and more efficient.
