How this service works
Official Swiss company registry lookup (Zefix). Query: /v1/eu/entreprise/CH/CHE-107.480.920 (UID, dots optional). Returns legal name, legal form, normalized status, registered office, cantonal register link, live from Zefix. 404, not billed: a Swiss sole proprietorship (Einzelunternehmen), a branch whose head office is not served, an undecided form. Same unified schema as every Sirenic European profile.
Output
A unified JSON object containing the company's legal name, legal form, normalized status (e.g. active/dissolved), registered office location, and a link to the cantonal commercial register entry — all sourced live from the Swiss Zefix registry, in the same schema as other Sirenic European company profiles.
Example use cases
Supplier due diligence before contract
“I'm about to sign a contract with a Swiss company and they gave me their UID CHE-356.789.012 — can you pull their official Zefix profile and confirm their legal name, legal form, and whether they're still active?”
Verify Swiss entity for KYC
“I need to verify the legal status of Swiss entity CHE-107.480.920 for a KYC check — please get me their official registered name, legal form, current status, and the cantonal register reference from Zefix.”
Cross-check Swiss company details on invoice
“I received an invoice from a Swiss company claiming to be 'Alpine Holding AG' with UID CHE-234.567.890 — can you check Zefix and confirm their legal name and registration status match what's on the invoice?”

Endpoint
GEThttps://api.sirenic.eu/v1/eu/entreprise/CH/:id?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to verify or enrich data about a Swiss legal entity using its official UID (CHE number) from the Zefix central register. Prefer it over generic web searches when you need authoritative legal name, status, and registration data for KYC, supplier verification, invoice validation, or compliance checks on Swiss companies. Choose it over other Sirenic country endpoints specifically for Switzerland (CHE prefix UIDs).
Side effects
- Invalid or malformed UID format — must match CHE-\d{3}.\d{3}.\d{3} pattern (with or without dots/dash)
- Company UID not found in Zefix — returns 404 or empty result
- Zefix upstream service temporarily unavailable — may return 503 or timeout
- Non-Swiss UID passed to Swiss endpoint — wrong country code (e.g. passing a French SIREN)
