IBAN Validation APIs
IBAN validation APIs check that an account number is valid, and most also tell you which bank it belongs to. IBAN Analyzer works without a key and resolves the bank's name, BIC and address. Bank Data adds SWIFT/BIC validation, IBANforge handles Swiss clearing numbers and sanctions screening, and EuroValidate bundles IBAN checks with VAT and EORI validation.
