Structure of the UK IBAN

The International Bank Account Number (IBAN) is an internationally agreed means of identifying bank accounts across national borders with a reduced risk of transcription errors. It was originally adopted by the European Committee for Banking Standards (ECBS), and later as an international standard under ISO 13616:1997. The current standard is ISO 13616:2007, which indicates SWIFT as the formal registrar initially developed to facilitate payments within the European Union; it has been implemented by most European countries and many countries in the developing world, especially in the Middle East and in the Caribbean.
