ARES company data: fields KYB teams actually use
Short summary
ARES, run by the Czech Ministry of Finance, exposes Commercial Register, Trade Register, and VAT data in a single response—more detail than most KYB teams realize. OpenRegistry preserves raw jurisdiction_data for audit trails, which matters when onboarding happens near insolvency filings or license suspensions. Key limitations: ARES is not a UBO register, lacks sanctions screening, and doesn't store historical snapshots.
- •ARES returns cross-register Czech company data in one call, more than most teams expect
- •Raw registry preservation matters for audit trails—screenshots aren't enough
- •ARES is not a UBO register and lacks sanctions/PEP/credit checks—those belong elsewhere
