FAQ
Frequently asked questions about the company database
A one-off export of an entire sector costs CZK 4,900 to 9,900 depending on the sector; you will find the exact price for each of the fifteen sectors in the sector overview.
By sector, region, district, city, street and postcode, by VAT-payer status (reliable, unreliable, not registered) and by whether the company has a phone, an email or both.
All companies in the given sector in our database, including the contacts available for them. For example, Construction & trades has 513,177 companies, of which 97,954 have a phone and 77,391 an email. We deliver the export in CSV or Excel, ready to import into a CRM or email tool. API access is available on request.
The data comes from public registers (ARES, the Commercial and Trade Register, the Ministry of Finance, the Insolvency Register) and from publicly available sources where companies published it themselves. Information about legal entities is not personal data; for sole traders and contacts to specific individuals it is personal data processed on the basis of legitimate interest (Art. 6(1)(f) GDPR). For their own outreach, the buyer is an independent controller: they need their own legitimate interest, must inform the recipient and must respect objections. Email marketing is governed by Act No. 480/2004 Coll., so every email must include the sender's identification and an option to unsubscribe. We're happy to help you set up your campaign.
A note on e-mail: under the Czech Data Protection Authority’s (ÚOOÚ) interpretation of Act No. 480/2004 Coll., an unsolicited e-mail offer without the recipient’s prior consent is illegal commercial communication — even when sent to a company. Use the database for phone, postal or in-person outreach, LinkedIn, and for verifying and enriching your own contacts; e-mail only existing customers or recipients who have given consent.
We refresh VAT-payer reliability, VIES and the Contracts Register data with repeated runs and change detection, for every company you can see when something changed. We don't sell one-off purchased lists; the database is continuously updated.
