The International Bank Account Number (IBAN) is a standardized system used to identify bank accounts across national borders. Introduced by the International Organization for Standardization (ISO 13616), IBAN was developed to simplify and improve the accuracy of international financial transactions, particularly in Europe. It ensures that money transfers between countries are processed smoothly, efficiently, and with minimal errors.

An IBAN is a unique alphanumeric code that can be up to 34 characters long, depending on the country. It typically includes a two-letter country code, two check digits for validation, and a basic bank account number (BBAN). For example, a German IBAN might look like this: DE89 3704 0044 0532 0130 00, where “DE” is the country code for Germany.

The main purpose of IBAN is to reduce delays and errors in cross-border banking by providing a uniform format for account numbers. When used correctly, it helps banks verify the validity of account information before a transfer is made. This significantly reduces the risk of funds being sent to the wrong account or being rejected due to incorrect details.

Today, IBAN is used in over 70 countries and is a key part of the Single Euro Payments Area (SEPA) in Europe. Although it was originally designed for European use, its adoption has expanded globally due to its effectiveness. In conclusion, the IBAN system has become a vital component of modern banking, facilitating faster and more secure international financial transactions.
