Short answer. The official source is the ARES (Administrative Register of Economic Entities). Start there, then check what a register does not show.
Where. ARES (Administrative Register of Economic Entities): https://ares.gov.cz/
What you can see for free. ARES lets you search economic entities registered in the Czech Republic and shows data held in the source registers it draws from (per the Ministry of Finance).
Steps.
What the register does not show. A registry record does not verify business activity, creditworthiness or sanctions status, and it is not a news check.
What a Dutiful report adds. For Czechia: registry profile, legal form, seat address, VAT number, status and business activities from the official register. Officers, owners and financial figures are not covered. Plus a sanctions screen (OFAC SDN and UK Sanctions List) and a public news and web scan, with sources. Sample: /sample.
