Frequently asked questions about the Switzerland KYB API
What company data can I verify in Switzerland?

Does the API return beneficial ownership (UBO) data for Switzerland companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Switzerland companies and exposes them as a recursive ownership org-chart (GET /v2/Companies/{caseCommonId}/org-chart), tracing control through holding companies to the individual beneficial owners. The depth available depends on what the ZefixWebApp discloses. See the UBO API.

Yes. The default document set for Switzerland includes Registry Extract, Company Registration, retrieved by default, with additional documents available on demand (Commercial register extrait – certified, Register document – certified, Statutes – certified, Certificate of incorporation – certified).
