Poland KRS Company Registry Scraper

Extract public Polish KRS company registry records by KRS number. The actor accepts one or many KRS numbers and returns normalized company identity, address, registration, representative, shareholder/partner, business activity, and capital fields from the official public registry response.

What you can do with it

• Enrich B2B lead lists with Polish company names, NIP, REGON, legal form, and address.
• Check compliance records for known KRS numbers in repeatable batches.
• Build market research datasets from official public registry extracts.
• Normalize pasted KRS numbers from spreadsheets into machine-readable JSON, CSV, or Excel exports.

Who is it for?

Compliance teams, sales operations, B2B data vendors, researchers, and analysts who already have KRS numbers and need structured company registry exports without manually opening registry pages one by one.

Legality

This actor extracts publicly available Polish KRS registry records for KRS numbers you provide. Use the data in line with applicable privacy, compliance, and database-use rules, especially when combining registry data with other personal or commercial datasets.

Tips and limits

• Use the correct register: most companies are in P; associations and foundations are usually in S.
• Keep maxConcurrency low for large batches to avoid unnecessary pressure on the public registry service.
• KRS numbers are normalized to 10 digits automatically.
• Personal identifiers in the official response can be masked by the registry; the actor returns what is publicly provided.

What should I include in a support request?

Please include the run ID or run URL, your input JSON, expected output, and actual output. If a specific KRS number failed, include that number and the selected register.
