Switzerland IBAN

Anatomy of the official example

CH9300762011623852957

• Country code
• Check digits
• Bank code
• Account number

The example comes from the ISO 13616 registry; it belongs to nobody. Positions count from the first character of the IBAN.

The check digits of this official example pass, yet SIX BankMaster (Swiss IID / BC-Nummer register) says nobody holds its bank code: that is exactly what our bank-code check catches, and what a checksum alone cannot see.

What the API checks on a Switzerland IBAN

• The length, the charset of every field and the mod-97 check digits.
• The bank code against SIX BankMaster (Swiss IID / BC-Nummer register), refreshed monthly: institution, matching BIC, status.
• The country's SEPA reachability and the open schemes (SCT, SDD).
• The Verification of Payee duty that does, or does not, bind the country's providers.
