Czech Company Lookup by ICO: Name, Address, Legal Form, VAT ID (ARES)

arescz/company-by-ico

Looks up one Czech economic entity in ARES, the Czech Ministry of Finance's register, by its 8-digit ICO (company identification number): registered name, registered seat (structured and as a single text line), legal-form code, tax office, date of establishment, VAT ID, NACE activity codes and the status of the entity in each underlying register. Field names are Czech. Keep leading zeros in the ICO. Entities include self-employed natural persons, whose names and addresses are personal data, so data-protection law applies to reuse. An ICO that no entity holds is refused as a validation error. ARES data are informative only, not an official extract; passed through unmodified and served by Eden Engine; not an official ARES product.
