How this service works

IBAN validation (ISO 13616 mod-97 and per-country length, SEPA membership; for Spain also the national CCC check digits and bank name). Computed locally, IBAN is not stored.

Output

A JSON object containing: the normalized IBAN (partially masked), a boolean 'valid' flag, the 2-letter country code, a boolean 'sepa_zone' indicating SEPA membership, the bank/entity name (for Spain), and an array of 'errors' describing any validation failures (e.g. wrong length, bad check digits, unknown country prefix).

Example use cases

Payroll IBAN sanity check

“Before I run payroll this week, can you validate all the employee IBANs in my list starting with DE89 3704 0044 0532 0130 00 — tell me if each one is valid and in the SEPA zone?”

Spanish bank account verification

“I have a Spanish IBAN: ES91 2100 0418 4502 0005 1332 — can you validate it, check the CCC digits, and tell me the bank name?”

B2B payment pre-flight check

“We're about to wire funds to a supplier who gave us GB29 NWBK 6016 1331 9268 19 — please verify that IBAN is valid and confirm it's a SEPA account before we proceed.”

When to prefer

Choose this endpoint when you need a privacy-preserving, locally-computed IBAN validation that does not transmit or store the account number externally. It is especially useful for Spanish IBANs where you need the additional CCC national check digit validation and the resolved bank name. Prefer it over generic regex checks when full ISO 13616 compliance and SEPA membership status are required in a single low-latency call.

Side effects

Malformed or unsupported country prefix returns valid=false with error details
Incorrect mod-97 check digit causes valid=false
Wrong length for the given country returns an error in the errors array
Entirely missing or empty IBAN field returns an input validation error
Non-string or null IBAN input may return a 400-level error
