When to prefer

Use this endpoint when you need to programmatically validate an IBAN before initiating a bank transfer, storing account details, or verifying user-submitted payment information. It performs the full ISO 13616 checksum (mod-97) plus country-code and length checks, making it more thorough than simple format regex.

Side effects

Invalid or malformed IBAN string returns validation failure details
Unsupported or unknown country code returns error
Empty input returns a validation error
Network timeout or service unavailability returns HTTP 5xx
