Frequently asked questions

Searching the directory

How the search works, what each filter means, and how the results come together.

What can I search for in the directory?
The search field matches company names, industries and places. Beyond that you can filter by Industry (18 categories based on the NOGA classification), Size (number of employees), Region (canton, language region or postal code) and Special (keywords and entry date). Filters combine freely; the active ones appear as chips below the filter bar and can be removed there individually.
How do keywords work?
Keywords search the description and stated purpose of each company — the text that goes beyond the company name. Multiple keywords are combined with OR: every additional keyword widens the set of matches rather than narrowing it.
What belongs in the postal code field?
A single postal code (e.g. 8000) or a range (e.g. 1000-1010). The field accepts postal codes only — for place names, use Canton or Language region.

How is organisation size determined?
Size reflects the number of employees and is calculated from publicly available information by a model developed in-house. It is a best-possible estimate, not an official figure.
What does the Verified label mean?
Verified means the entry is tied to a UID (Swiss business identification number) and therefore links back to the official Swiss business register. The label speaks to the company's identity — it is not a rating of its performance.

Source: Federal Statistical Office, UID register

How do I sort the results?
Use the dropdown above the list: Relevance, Name (A–Z), Best rating, Most reviews or Longest established. You can also switch between list and map view and set how many results appear per page.
