What Is an IBAN?

An International Bank Account Number (IBAN) is a standardized international numbering system developed to identify bank accounts across national borders. It was originally adopted by the European Committee for Banking Standards (ECBS) and later became an international standard under ISO 13616.

IBAN Structure

Every IBAN consists of the following components:

  • Country Code (2 letters): ISO 3166-1 alpha-2 code (e.g., GB, DE, FR).
  • Check Digits (2 digits): Calculated using MOD-97 algorithm for error detection.
  • BBAN (Basic Bank Account Number): Country-specific format containing the bank code, branch code, and account number.

Frequently Asked Questions

How is an IBAN validated?

IBAN validation uses the MOD-97 algorithm (ISO 7064). The country code and check digits are moved to the end, letters are converted to numbers (A=10, B=11, ..., Z=35), and the resulting number must give a remainder of 1 when divided by 97.

Do all countries use IBAN?

Over 80 countries use IBAN, primarily in Europe, the Middle East, and parts of Africa and the Caribbean. The United States, Canada, Australia, and New Zealand do not use IBAN.

Is IBAN the same as a SWIFT/BIC code?

No. An IBAN identifies a specific bank account, while a SWIFT/BIC code identifies the bank itself. International transfers often require both.
