IBAN Structure Switzerland

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

Switzerland's IBAN is 21 characters long and follows the pattern CHkk BBBB BCCC CCCC CCCC C. After the country code CH and two check digits come a 5-digit bank clearing number (BC number) and a 12-digit account number. The BC number is assigned by SIX Interbank Clearing and uniquely identifies each Swiss bank. Although Switzerland is not an EU member, it participates in SEPA, so euro transfers between Switzerland and the euro area ride SEPA. The national currency is the Swiss franc (CHF): euro payments travel over SEPA, while CHF payments usually run over SWIFT, where a BIC is often still required and FX margins can apply.
