IBAN.com operates as a web-based portal for real-time identification, validation, and calculation of International Bank Account Numbers (IBAN). This platform uses algorithmic formulas to determine the validity of an IBAN. The IBAN Validation API allows user to query the existence and validity of IBANs using check digits. It provides access to many other features including the validation of domestic bank code, IBAN issuer, and country-specific IBAN length, code, and structure as well as the issuing bank’s address. Developers can use simple HTTP GET or POST requests to initiate the automation of IBAN validation processes. The API supports JSON and XML-formatted requests and responses.
