How this service works
Use when you need to check whether an IBAN is valid and extract its country, bank code and check digits.
Output
A JSON object with a boolean 'valid' field, a nullable 'country' string (ISO country code), a nullable 'bank_code' string, a nullable 'check_digits' string, and a nullable 'error' string explaining any validation failure.
Example use cases
Pre-payment IBAN sanity check
“Before I wire money to this account, can you verify that the IBAN DE89370400440532013000 is valid and confirm which country and bank it belongs to?”
User-submitted form validation
“A user just entered FR7630006000011234567890189 as their bank IBAN in our onboarding form — is it valid, and what bank code and country does it contain?”
Bulk reconciliation spot check
“I've got this IBAN from an invoice: NL91ABNA0417164300 — can you quickly tell me if it checks out and what components it breaks down into?”
Technical details
Endpoint
GEThttps://tools.rocketman.dev/v1/iban/validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap, single-call IBAN validation that also returns parsed components (country, bank code, check digits) without setting up a local library or handling the complex IBAN checksum algorithm yourself. Ideal for payment flows, form validation, or data enrichment pipelines where IBAN accuracy is critical.
Side effects
- IBAN with invalid check digits returns valid=false with an error message
- Malformed or empty IBAN string returns valid=false with an error description
- Unsupported or unknown country prefix may result in null bank_code or country
- Network or service errors may return non-200 HTTP responses
