For corporate clients/banks:

CSV Mass Calculations: Calculate or validate thousands of IBANs in one step. Simply export your data into the CSV format, upload the file, and wait a few minutes.
SOAP Web Service: Integrate the IBAN calculator into your own processes, or perform mass calculations without the formatting problems that sometimes occur with the CSV method.
Downloadable Windows or Linux Executable: For Germany, we offer a command line version of the IBAN calculator. It runs under Windows or Linux. Contains the current German bank codes and BICs and is updated every quarter.
Data: if you'd rather want to use your own software, but benefit from our data collection service, you might like our data subscription.
