The International Bank Account Number (IBAN) is a bank account number structured according to the ECBS (European Committee for Banking Standards) standards. The IBAN was originally developed to facilitate payments within the European Union. Apart from most European countries, IBAN has now been adopted by a few other Middle Eastern countries as well. You can download the latest update of countries supporting IBAN from the SWIFT website. Sri Lanka like most other Asian countries, USA and Australia use the current Bank Identifier Code system (BIC or SWIFT code) in conjunction with the BBAN (Basic Bank Account Number).
