What This Actor Does

ARES is the official register of economic subjects in the Czech Republic. This Actor turns it into structured company data. For each company it returns:

• Identity — company name, IČO (company ID) and VAT number (DIČ)
• Legal — legal form (code + label) and incorporation/dissolution dates
• Location — full address, street, city, district, region and postal code
• Industry — NACE activity codes
• Link — the ARES profile URL

Search by company name (paginated across all matches) or look up exact IČO numbers to verify specific companies.

Why Use This

• KYC & due diligence. Verify Czech companies by IČO, VAT, address, legal form and status — the identifiers compliance needs.
• IČO + VAT in one. The IČO and DIČ are the universal identifiers for Czech businesses — ideal for matching and enrichment.
• Name search or exact lookup. Sweep a keyword across the register, or verify a list of IČO numbers.
• Clean and free. Reads the official public ARES API — no key, no anti-bot, no browser.

Tips

• IČO is the primary company identifier; DIČ (VAT) is the tax identifier — both are key for matching.
• Name search paginates across all matches; IČO lookup verifies exact companies fast.
• NACE codes classify each company's activities for sector filtering.
• Schedule it with Apify Schedules to monitor changes.
