What is an IBAN Number?

An International Bank Account Number (IBAN) is an internationally agreed code to identify the country of origin for foreign transactions. It is not a replacement for your bank account number or sort code; however, it is a unique number beginning with the country code.

It is an alphanumeric number starting with the 2-digit country code. Notably, it includes up to 34 alphanumeric combinations which highlight bank code, branch code and bank account number in addition to the country code.
