About

IBAN is the standard for bank account numbers in Europe and a few countries outside Europe. The IBAN API let you check if an IBAN is valid or invalid. There is a more extensive check for Dutch IBANs. The last 10 digits of these are also checked on the basis of the 11-point test. This detects common typos.

Why use our API

  • 100% correct validation guarantee
  • Gives bank names
  • Up to 100,000 requests per month
  • Accepts numbers of 44 countries
  • Additional check for Dutch IBAN numbers; Also for banks like Bunq with a different IBAN structure
  • We are continuing to research in order to maintain quality

Although it is possible to set up your own IBAN validator, the maintenance for an extensive check is time-consuming over the years; You also need to create an alert system that detects changes in the official banking list. Approximately there are 6 changes per year in the Dutch bank list. Many companies choose a service like Tuxx API to check APIs.
