What is IBAN?
The International Bank Account Number (IBAN) is a system to identify bank accounts across national borders with a minimal risk of propagating transcription errors. It was initially adopted by the European Committee for Banking Standards (ECBS) and later as an international standard under ISO 13616:1997. The primary purpose of the IBAN is to facilitate the automatic processing of cross-border transactions, ensuring fast and accurate transactions.
The IBAN is a series of alphanumeric characters that uniquely identify a customer's bank account held at a bank anywhere in the world, though its adoption varies by country. The system is designed to standardize the identification of bank accounts across national borders to facilitate international payments with reduced risk of transcription errors.
How is IBAN Constructed?
The structure of the IBAN is defined under ISO 13616-1:2007 and is composed of up to 34 alphanumeric characters. These characters are arranged in a specific order to provide a unique identifier for the bank account, which can be broken down as follows:
- 1. Country Code: The first two letters represent the country code of the account-holding country, using ISO 3166-1 alpha-2 country codes (e.g., 'GB' for the United Kingdom, 'PL' for Poland).
- 2. Check Digits: Following the country code are two check digits used for validation, calculated using a mod-97 operation as specified by ISO 13616-1.
- 3. Bank Identifier: The next few characters (length varies by country) identify the account holder's bank, such as a bank's routing number or sort code.
- 4. Account Number: The remainder of the IBAN includes the account number, branch identifier, and possible routing information, varying in length and format by country.
The precise structure of the IBAN for each country is defined by its national banking authority, and the length and composition can vary. However, no IBAN can exceed 34 characters.
Although the IBAN is used internationally, adoption varies. Countries using IBAN have specific formats and lengths, defined by their banking standards, but must conform to the international standard for interoperability.
