Bank data validation
The service for Bank data validation includes the functionality for bank data validation, account number validation as well as credit card number and IBAN plausibility check.
We would like to point out explicitly that the bank server is not able to determine whether an IBAN / account number has actually been assigned. The validation can only state whether a given IBAN / account number is valid (syntactically correct) or not. An invalid IBAN / account number cannot be assigned by the respective bank, a valid IBAN / bank account number, however, may have been assigned, but this is not necessarily the case.
