What is an IBAN?
IBAN (International Bank Account Number) is an internationally agreed system to identify bank accounts across national borders. It consists of a country code, two check digits, and a Basic Bank Account Number (BBAN).
How is IBAN validated?
IBAN validation checks: 1) Country code format, 2) IBAN length for the specific country, 3) Character format (alphanumeric), 4) Checksum using MOD 97 algorithm. A valid IBAN passes all these checks.

Over 80 countries support IBAN, primarily in Europe, the Middle East, and North Africa. Each country has a specific IBAN length and format defined by the ISO 13616 standard.
