A Switzerland IBAN starts with the country code CH, followed by 2 check digits and the national account number (BBAN), for a total of 21 characters. ValidateFin verifies the mod-97 checksum (ISO 13616), the length and the format - entirely in your browser, no data sent to any server.
- •The 5-digit bank code is the Swiss clearing number (IID/BC number) maintained by SIX, identifying the institution.
- •Switzerland also issues QR-IBANs (clearing numbers in the 30000–31999 range) used with the QR-bill payment system — the validator accepts both.
- •Switzerland is not in the EU but is part of the SEPA zone, so a CH IBAN is accepted for euro SEPA transfers; domestic accounts are in Swiss francs (CHF).
