International Bank Account Number

The IBAN is crucial in cross border payments as it aids in preventing potential operational problems. This article is going to explore everything you need to know about the IBAN number. Stay tuned!

What is IBAN Number?

An IBAN, or as said, International Bank Account Number, is a unique number used to identify bank accounts in international money transfer and helps to facilitate the processing of cross border payments by standardising the format of account numbers.

The IBAN consists of letters and numbers, and its structure varies depending on the country. In general, it is made up of several parts:

The country code: 

This is a two-letter code that indicates the country where the bank account is held. For example, "DE" for Germany, "FR" for France, and so on.

The check digit:

 This is a single digit used to confirm the validity of the IBAN. It is calculated using a specific algorithm and helps detect errors in the IBAN.

The bank code: 

This is a code that identifies the bank that holds the account. The format and length of the bank code vary depending on the country.

The account number: 

This is the actual account number of the bank account. It is usually made up of letters and numbers, and its format and length also vary depending on the country.

IBAN is used in international money transfers between countries in the European Union and many other countries worldwide. It helps to ensure that the money reaches the correct bank account by providing the necessary information about the bank and account holder. The IBAN facilitates the automatic processing of payments by eliminating the need for manual verification of the account number and bank code, which can efficiently reduce the risk of errors.

When making international money transfers using IBAN, you must provide the recipient's IBAN, the account holder's name, the bank's name, and the SWIFT/BIC (if needed). This ensures that the transfer is directed to the correct bank account and the proper account holder.

How to find an IBAN?

An IBAN is a unique number assigned to bank accounts in various countries. There are several ways to find your IBAN number, depending on your bank and the country where your account is held.
