An IBAN, or International Bank Account Number, is a series of alphanumeric characters that identifies a customer account held at a bank anywhere in the world. An initiative driven by the European Commission, the adoption of a standard account number is credited with reducing the number of errors in international payment processing.
Understand the number. The first two characters are ISO (International Standards Organization) country codes followed by the domestic bank code and account number. The country code indicates the country in which the IBAN was issued. This format ensures payments are processed correctly. The order (and example) is: Country Code (GB), Check Digits (98), Bank Code (RBOS), Sort Code (123456), Account No. (123456789).
Determine if you're looking for an IBAN in an electronic or printed form. IBANs printed in paper form are split into groups of four characters. Electronic IBANs do not contain spaces or include the word IBAN. Following is an example of each: Paper form : GB99 RBOS 1234 56 78 9156 78 Electronic form : GB99RBOS12345678915678
