Swiss contact database: buy company addresses for sales and CRM

A whole industry costs CHF 219 to CHF 439 depending on the industry, as a one-off final price without a subscription. Selections by canton, municipality, language region or additional filters receive an individual quotation. The price list shows the price of each industry.

On 4 November 2026 it held 1,005,992 records: all 796,383 active entities in the commercial register and 209,609 places from Overture Maps that could not be matched to an entity with certainty. 264,448 records have a phone number, email or website. The written quotation states scope, fields, reference date and delivery date of your selection; a request is not an order. Details on the page Database status.

Not without consent. Anyone who sends mass advertising by email, SMS or fax must obtain the recipients’ consent beforehand, and this applies to businesses as well (Art. 3 para. 1 let. o UWG, the Swiss Unfair Competition Act). The only exception is advertising for your own similar offers to customers whose contact details you received in a sale. An export from kontaktdatenbank.ch contains no consent. The email field is meant for matching records in your CRM.

Sales calls are allowed to numbers listed in the telephone directory without the asterisk marking. Ignoring the marking is unfair competition, and numbers that are not listed at all are treated like numbers with an asterisk (Art. 3 para. 1 let. u UWG). You must also call from a displayed number that is listed in the directory (let. v). We do not currently offer a check against the asterisk marking; phone numbers in the export are not checked and are not intended for sales calls. Overview: B2B marketing in Switzerland.

The UWG does not require prior consent for addressed letters to businesses. Respect a declared objection, though: data on sole proprietorships and named individuals are personal data, and processing them against a person’s express wishes can infringe their privacy (Art. 30 para. 2 let. b of the Federal Act on Data Protection, FADP).

Yes. The standard is a UTF-8 CSV file with semicolons as separators that opens in Excel; on request we deliver XLSX or JSON. The page Export and sample file lists the columns and provides a sample with fictitious companies.

The business identification number (UID, format CHE-123.456.789). It identifies a legal entity permanently and is not reassigned after deletion. Where no UID is assigned, for example for unregistered sole proprietorships, matching needs additional attributes; identical names alone are not enough.

So far the records of the Swiss company database come from two public sources: the commercial register (Zefix via LINDAS, open government data of the Federal Commercial Registry Office) and the open places data of Overture Maps (Places, licence CDLA Permissive 2.0). Planned are the legal notices on company websites, OpenStreetMap, open data from cantons and federal offices and individual look-ups in the FSO UID register; they are not yet included in the figures. The commercial register is public (Art. 936 of the Code of Obligations); the Federal Commercial Registry Office publishes its entries as open government data that may be used with attribution. We do not use directories whose terms of use prohibit copying into address databases. Details for each source: data sources and methodology.

Under the Swiss Data Protection Act, information about legal entities is not personal data. For sole proprietorships and named contact persons the FADP applies and, because the operator is based in the EU, the GDPR as well. Information on the processing is on Data subject rights; you can object at any time via Objection. As a buyer you are responsible for your own use of the data.

We confirm the reference date of your delivery in the quotation. We do not promise a fixed update interval for every single contact. The page Database status shows which figures we publish, with which date, and how we count.
