How this service works
Validate an IBAN's format and mod-97 checksum, derive its country code, and optionally compare it to an expected country. Format/checksum/country only — no bank-account verification.
Output
Returns the normalized IBAN, the extracted two-letter country code, a boolean indicating whether the format is valid, and (if an expected country was provided) a boolean indicating whether the IBAN's country matches the expected country.
Example use cases
Example prompt
“Can you check if this IBAN is valid and confirm it's from the Netherlands: NL91 ABNA 0417 1643 00?”
Technical details
Endpoint
POSThttps://gateway.apiosk.com/financial-validation/iban-country-checkWhen to prefer
Use this endpoint when you need to validate an IBAN's structural format and/or verify its country of origin before initiating a payment or onboarding a bank account. Prefer this over generic string validation when IBAN-specific country-code extraction and cross-checking are needed.
Side effects
- Malformed IBAN string that cannot be parsed — returns format_valid: false
- Expected country code not a valid ISO 3166-1 alpha-2 code — may return an error or unexpected result
- Network or gateway timeout — HTTP 5xx error
- Missing required iban field in request body — HTTP 4xx validation error
