For corporate clients / banks:

SOAP or REST Web Service: Integrate the IBAN calculator into your own processes.
Mass Calculations: Calculate or validate thousands of IBANs in one step. Export your data into the XLS (Excel) or CSV format, upload the file, and wait a few minutes. There is also an sFTP interface available for batch processing.
Our IBAN validations go way beyond the checksum check. We also check the domestic bank codes and account numbers which are embedded in IBANs. To facilitate fraud prevention, we crawl the Web for IBANs and, if an IBAN you validate has been found on the Web, report this to you. Last, but not least, we provide a mechanism for checking not only if an IBAN is formally correct but also if it actually exists and belongs to a given account holder.
