MoreBank data validation
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.
IBAN syntax check
Check IBANs for a valid structure, correct length and checksum. This helps you catch typos and transposed digits before a payment fails. Additional bank validation against real bank directories is available for the countries listed above.
API and automation
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.
