Data source

Data is fetched from the official ARES REST v3 API operated by the Czech Ministry of Finance. ARES aggregates records from the main Czech company registers:

  • VR — Obchodní rejstřík (Companies Register, Ministry of Justice)
  • RŽP — Živnostenský rejstřík (Trade Licensing Register)
  • RES — Registr ekonomických subjektů (Czech Statistical Office)
  • ROS — Registr osob (Persons Register)

Approximately 5 million registered economic subjects are accessible via the API. The IČO is the canonical identifier for Czech business data — it links to tax records, procurement databases, and court filings.
