How this service works
Validate an IBAN: country, correct length, ISO 13616 checksum, bank code and BBAN, with a reason when invalid (likely typo, wrong length). Works offline for about 80 countries. Use before sending a bank transfer or saving payout details.
Output
Returns a structured object indicating whether the IBAN is valid, plus parsed components (country code, bank code, BBAN) and, if invalid, a human-readable reason such as wrong length, checksum failure, or unrecognised country code.
Example use cases
Pre-transfer IBAN check
“I'm about to wire money to a supplier — can you validate this IBAN before I confirm the transfer: DE89 3704 0044 0532 0130 00?”
Payout form validation
“A user just entered their IBAN FR76 3000 6000 0112 3456 7890 189 into our payout form — is it valid or is there a typo?”
Bulk onboarding sanity check
“We're onboarding a new vendor and they gave us the IBAN NL91 ABNA 0417 1643 00 — run a validation on it and tell me if the checksum and bank code are correct.”

Endpoint
GEThttps://bess-x402.onrender.com/v1/finance/iban?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need offline, instant IBAN validation covering ~80 countries with full ISO 13616 checksum verification, bank code parsing, and actionable error reasons — ideal for pre-transfer checks, form validation, and payout onboarding flows where you want structured feedback rather than a simple pass/fail.
Side effects
- Invalid or unrecognised country code returns validation failure with reason
- Checksum mismatch returns failure indicating likely digit transposition or typo
- Wrong length for the declared country returns reason citing expected vs actual length
- Unsupported or uncommon country (outside ~80 supported) may return limited detail
- Missing iban query parameter returns a 400-level error
- Malformed request returns error without IBAN details
