Bank data validation

Validation against bank directories

IBAN-Test goes beyond checksum-only validation. For these countries, we check the bank identifier against available bank directories and return bank details such as institution, city and BIC when available. See how IBAN validation works.

API and automation

Automate bank-aware IBAN validation

Validate structure and check digits, then use available bank-directory data in payment forms, SaaS products, SEPA workflows and AI agents. Automate through REST or MCP.
