What does IBAN stand for?

IBAN stands for International Banking Account Number and it is used to identify bank account details of a recipient. The format of an IBAN consists of a two digit country code, two check numbers, a four digit bank code, a six digit bank branch code and an eight digit bank account number. 

Who uses IBAN numbers?

The system was originally developed by the European Committee of Banking Standards (ECBS) in 1997, as a way of creating a standardised method of identifying international bank accounts. The system has since been adopted by banks and financial institutions in countries all over the world, with 80 regions now using IBAN numbers.

How does an IBAN work?

Used when transferring money overseas to a foreign country, IBAN numbers are formatted in the following order, containing the following information:

  • Country code – A code that is specific to a certain country
  • Check number – A two-digit code used as a redundancy check to detect errors on identification numbers
  • Bank identifier – The unique identifier for the domestic bank
  • Account number – The bank account identifier

What is an IBAN calculator?

Unlike an IBAN checker, which checks if an IBAN number is correct by confirming information such as the BIC/SWIFT code, bank name, address and country, a calculator is used to calculate exact bank account information for those who need to find out an IBAN. 

Banks arrange national or local account details into a string of alphanumeric characters and so IBAN calculators are used to convert this information into the International Bank Account Number needed when transferring funds to an international account.

What are the best IBAN calculators?

The official IBAN website has its own calculator, which effectively lets you calculate an IBAN number using the bank code and account number.
