IBAN
International Bank Account Number - a standardized international bank account identifier used across European and many other countries.
Full Explanation
An IBAN (International Bank Account Number) is a standardized way to identify bank accounts internationally. IBANs are used primarily in Europe and some other regions. An IBAN contains the country code, check digits, and the domestic bank account number. For example, a UK IBAN starts with "GB". IBANs make international transfers more reliable by reducing errors.
