How this service works
Validate an IBAN (international bank account number): ISO 13616 mod-97 check digits and per-country length registry for 88 countries. Returns formatted IBAN and BBAN. Use when someone enters a bank account (IBAN) and you must catch typos before a transfer.
Output
Returns a JSON object with: 'valid' (boolean indicating if the IBAN passes mod-97 and country-length checks), 'iban' (the raw input), 'formatted' (space-separated IBAN groups e.g. 'DE89 3704 0044 0532 0130 00'), 'bban' (the Basic Bank Account Number portion), 'country' (ISO country code), and 'check_digits' (the two-digit mod-97 check digits).
Example use cases
Pre-transfer IBAN typo check
“I'm about to send €2,000 to this account number: GB29NWBK60161331926819 — can you validate the IBAN before I confirm the transfer so I don't lose the money to a typo?”
Customer onboarding bank verification
“A customer just entered their bank account as FR7630006000011234567890189 during signup — validate that IBAN and tell me if it's legitimate so I can approve their payout setup.”
Batch invoice payment prep
“We have a supplier IBAN of NL91ABNA0417164300 — run a quick validation on it and confirm the country and formatted version before we add it to our payment run.”
Technical details
Endpoint
POSThttps://toolrail.dev/validate/iban?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, instant IBAN check before initiating a financial transfer or onboarding a bank account — especially useful for catching typos. It covers 88 countries and applies both the ISO 13616 mod-97 algorithm and per-country length validation, making it more thorough than a simple regex check. Prefer it over general-purpose validation libraries when you need a hosted, pay-per-call service that also returns a clean formatted IBAN and BBAN extraction without deploying your own code.
Side effects
- Invalid IBAN fails mod-97 check — returns valid:false with no formatted output
- Country code not in the 88-country registry — may return invalid even if structurally plausible
- Malformed input (non-alphanumeric characters, empty string) — likely returns valid:false or an error response
- IBAN with correct length but wrong check digits — caught and returns valid:false
- Network timeout or service unavailability — returns HTTP 5xx error
