Is ARES company data free?

Yes. ARES (Administrativní registr ekonomických subjektů) is the Czech Ministry of Finance's official company registry, published as open data via a free REST API — no key, no login, no scraping. Free for commercial reuse.

An IČO is the 8-digit identification number assigned to every Czech company or sole trader. It is the reliable key for exact lookups. The DIČ is the separate VAT number for VAT-registered subjects.

Does it include directors?

Yes, on demand. From the public register (Veřejný rejstřík) you can attach the statutory body / board of directors (names, roles, tenure), the supervisory board, and the registered share capital as an opt-in enrichment.

How many companies are covered?

The ARES registry covers over 3 million Czech economic entities — the whole register. You can search by name, look up exact IČO numbers, and filter by address or active status.

How to get Czech company data from the ARES registry

Czech companies are registered in the official ARES registry (Administrativní registr ekonomických subjektů), run by the Ministry of Finance. Here's how to pull a company's identity, IČO, VAT (DIČ), legal form, NACE activity, address, board of directors and share capital as clean JSON — for KYC, KYB and B2B research.

IČO & VAT (DIČ) are the keys

An IČO is the 8-digit identifier assigned to every Czech company or sole trader — the reliable key for exact matches. The DIČ is the separate VAT number, present only for VAT-registered subjects. Numbers beat names, which can repeat or change.

What data can you get?

Identity — registered name, IČO, VAT (DIČ), legal form, founding date.
Activity & address — CZ-NACE codes, registered seat, active status and registers.
Directors & capital (opt-in) — statutory body / board (names, roles, tenure), supervisory board and registered share capital.
Filters — company name, exact IČO list, address, active-only.

The easy way (by name or IČO)

ARES offers an official REST API, but you still have to page it and stitch the public register for directors. Instead, the Czech Company Data scraper on Apify takes a name or a list of IČO numbers and returns a structured profile — no key, no setup, exportable to JSON / CSV / Excel.

Use cases: KYC / KYB & due diligence on Czech counterparties, VAT (DIČ) verification, board / director mapping, CRM enrichment on IČO, and market & competitor research.
