How this service works
Validates an IBAN (MOD-97 checksum and country length, computed here) and, if it passes, looks up the bank name, city and BIC (SWIFT) through OpenIBAN's public validation. The bank lookup depends on OpenIBAN's directory and may be missing for some banks; a valid checksum does not prove the account exists.
Output
Returns a JSON object with the normalized IBAN string, boolean flags for overall validity, checksum correctness, and country length compliance, plus bank details (name, city, BIC, bank code) sourced from OpenIBAN, the OpenIBAN validation status, the source URL used, and a timestamp. Bank details may be absent if the bank is not in OpenIBAN's directory.
Example use cases
Verify supplier bank details before payment
“Before I wire money to this supplier, can you check if this IBAN is valid and tell me what bank it's registered to: GB29 NWBK 6016 1331 9268 19?”
SWIFT code lookup for international transfer
“I need the BIC/SWIFT code for this IBAN so I can complete an international wire: FR76 3000 6000 0112 3456 7890 189 — can you look it up?”
Onboarding form IBAN verification
“A new customer filled in their bank account as NL91 ABNA 0417 1643 00 — can you confirm the IBAN is valid and tell me the bank name and city?”
Technical details
Endpoint
GEThttps://api.fadeandco.workers.dev/api/agent-intel/iban-routing-swift-resolver?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both IBAN format/checksum validation AND bank identification (name, city, BIC/SWIFT) in a single call. It performs the MOD-97 check locally and enriches with OpenIBAN's directory, making it suitable for payment onboarding, supplier verification, and international wire preparation workflows. Prefer it over raw IBAN regex checks when bank routing metadata is needed.
Side effects
- Invalid checksum returns valid=false with checksumOk=false
- Unsupported country code returns invalid length/format
- Bank not in OpenIBAN directory returns valid IBAN but missing bank name/BIC
- Malformed IBAN string (non-alphanumeric) may return error or invalid flags
- OpenIBAN external service unavailable may result in missing bank lookup data despite valid checksum
