Poland KRS Companies: Polish Company Register (KRS) Data API

Poland KRS Companies exports company data from the KRS (Krajowy Rejestr Sądowy, National Court Register), Poland's official register of companies, associations and foundations, as clean JSON, CSV or Excel. It reads the Ministry of Justice's official open KRS API (api-krs.ms.gov.pl), published on dane.gov.pl as open data in the public domain (CC0), so you can reuse the data freely. No login, no API key, no browser, no proxy.

• ✅ Look up any KRS number: name, legal form, NIP, REGON, registration date, registered address, email and website.
• ✅ PKD activity codes: main and other activities with descriptions.
• ✅ Share capital, representation rules, management board functions, supervisory board and commercial proxies (prokurenci).
• ✅ Filed documents: annual financial statements, auditor reports, approval resolutions and management reports, with filing dates and periods.
• ✅ Delta feed: every company with a new register entry on given days, from the official daily KRS Biuletyn.
• ✅ New companies feed: only companies first registered in your date range, for fresh B2B leads.
• ✅ Both registers: entrepreneurs (P) and associations, foundations and other organisations (S).

Values are in Polish, as registered. filedDocuments lists notices of filed documents (annualFinancialStatement, auditorReport, approvalResolution, managementReport), not the documents themselves. section6Entries names register section 6 entries (liquidation, bankruptcy, mergers, transformations).

Personal data: the register itself masks people's names (e.g. J**** K********); they are exported exactly as published and never unmasked. PESEL numbers and birth dates are not exported, and PESEL numbers written into free text are redacted. Shareholder and partner lists are not exported.

How much does it cost to get Polish company data?

• $0.003 per company record ($3 per 1,000).
• $0.00005 per run start. Platform compute is included.
• Companies skipped by Newly registered only and KRS numbers that are not found are not billed.

FAQ

Is this legal? Yes. The data comes from the Polish Ministry of Justice's official KRS API, listed on dane.gov.pl as open data under CC0 (public domain). The actor makes plain, polite GET requests (at most 3 in parallel, with pauses) and identifies itself.

What is a KRS number? The 10-digit number of an entity in the National Court Register, e.g. 0000019193. It is printed on Polish invoices and websites next to NIP and REGON.

Can I search by NIP, REGON or name? Not yet: the official API looks up by KRS number. Use the delta feed to discover companies by date.

How fresh is the data? Each record is the current extract (odpis aktualny) at run time. The Biuletyn lists entries made on each day, usually by the next morning.

How many companies change per day? Typically 3,000-10,000 on working days; a few hundred on weekends.

Why is a KRS number not found? It may be deleted, never assigned, or only in the other register (use register: "auto").
