What is an IBAN?

An IBAN, or International Bank Account Number, is a banking code which is used to identify the account of a customer at a financial institution. The IBAN system was designed to reduce this risk of errors when sending money abroad. An IBAN is formatted to consist of all the relevant information needed to transfer funds from one bank to another. IBANs were originally used for transfers with the Eurozone only, but due to the success of this identification method, they are now used across the globe and have become a standardised mode of communication. 

Why would I need to use an IBAN? 

IBANs are used to facilitate cross-border transactions sent from a benefactor in one country, to a payee in another country, streamlining the process and reducing the chance of erroneous payments. Customers will need to find out the IBAN of their payee before they can make an international money transfer online, over the phone or in-person. Find out how to locate an IBAN by reading our guide on the subject.

What is an IBAN validator?

As the name suggests, an IBAN validator is a tool which enables users to verify and validate International Bank Account Number details. This tool makes it possible for the sender to validate the routing information prior to submitting the payment, avoiding delays and bypassing potential mistakes. 

Due to the growing prominence of online banking and digital remittance platforms, customers may have appointed their bank the responsibility of finding and validating an IBAN, heading to their local branch or calling up to conduct the validation process. However, nowadays, it is possible to verify an IBAN yourself, entirely online. This means customers are able to confirm their recipient’s bank details quickly and securely, transferring funds instantly, the money reaching your recipient before you even made it to your local bank branch. 

What does an IBAN validator check?

The programming of an IBAN validator makes it possible to conduct the following checks:

  • Country code
  • The number of characters in the IBAN correspond with the number specified for the relevant country code
  • BBAN  (Basic Bank Account Number) format matches the relevant country code
  • Account number, bank code and country code is compatible with check digits

IBAN validators are also sometimes known as IBAN checkers: read more about these here.
