An IBAN or International Bank Account Number is a standardized international account number made up of up to 34 letters and numbers to identify bank accounts across countries. Each country has its own sequence, not exceeding 34 characters. IBAN is commonly used in Europe and other regions for making or receiving international payments.

An IBAN comprises data used to authenticate your account number, your bank’s country of origin, and other account information. During a payment, the code is validated to ensure the receiver exists. Transactions fail if an IBAN is invalid. With an IBAN checker, banks can confirm the number is error-free.
