How this service works
Validate an IBAN offline against the ISO 13616 registry: country and length check, ISO 7064 MOD-97-10 checksum, BBAN extraction, durable audit receipt.
Output
Returns a structured validation result indicating whether the IBAN is valid, the extracted country code, expected vs actual length check result, MOD-97-10 checksum pass/fail, the extracted BBAN (Basic Bank Account Number), and a durable audit receipt suitable for compliance logging.
Example use cases
Pre-payment IBAN sanity check
“Before we wire the invoice payment, validate the supplier's IBAN GB29NWBK60161331926819 and make sure the checksum and country format are correct.”
KYC compliance audit trail
“I need to validate the customer's IBAN NL91ABNA0417164300 as part of our onboarding flow and get a durable audit receipt I can store for compliance records.”
Bulk supplier bank account verification
“We just received a new supplier bank record with IBAN FR7630006000011234567890189 — can you verify it's a properly formatted valid IBAN before we add it to our payment system?”
Technical details
Endpoint
GEThttps://lookups.nl/iban/:numberWhen to prefer
Choose this endpoint when you need offline, deterministic IBAN validation with a cryptographically verifiable audit receipt — ideal for compliance workflows, pre-payment verification, and KYC processes where you need proof of validation. It does not require an external banking API call, making it faster and more reliable than live bank registry lookups.
Side effects
- Invalid IBAN format returns validation failure with specific error (wrong length, bad checksum, unknown country code)
- Non-existent or unsupported country code prefix causes country check failure
- Malformed input (non-alphanumeric characters) may return a parse error
- Network timeout on the API call
