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 IBANs. The IBAN SWIFT/BIC Validation API allows developers to integrate BIC code authentication functionality in applications. It simplifies access to the BIC code directory and makes it easier for users to validate SWIFT and BIC codes in banking transactions. The API sends HTTP-formatted requests and returns responses in JSON or XML format.
