Each company is one row with 15 columns: name, legal form, NIP, REGON, KRS, street, postcode, town, voivodeship, county, industry (by source category), PKD code (where available), phone, email and website. Not every field is filled in – it depends on the source, and we never fill empty fields with estimates. Column description and sample file: export format and sample file.
You can narrow the list to selected counties or towns and to records that have the fields you need, for example a postal address and a website. One-off file as CSV (UTF-8), XLSX or JSON, no subscription.
From publicly accessible sources: business directories, OpenStreetMap and professional registers and lists. The full list is in the methodology. Our own database, built region by region, is one of these sources and today has the most records from this voivodeship – see the figures below.
As of 17 September 2026. We assign the voivodeship based on the company address; some records without an assigned region may also be in Mazowieckie. The voivodeship has 37 counties and 5 cities with county rights (Warsaw, Radom, Płock, Siedlce, Ostrołęka); in Warsaw a list can be narrowed approximately to districts by postcode.
No. The GUS figure of 939,049 entities shows the size of the market. Our export contains companies found in public sources; how many of them meet your criteria (industry, counties, required fields) we state before you order.
Yes. The export has “county”, “town” and “postcode” columns, so a list can be limited to any set of counties or towns in the voivodeship.
Only towards recipients who have given prior consent. Article 398 of the Polish Electronic Communications Law prohibits sending commercial information by email or phone without the prior consent of the subscriber or end user; it does not distinguish between consumers and businesses. The export contains no consents. More: B2B telemarketing and email in Poland after the change.
The price is given on request, once the industry, counties and required fields are agreed. You get the number of records first, then the price. All prices are final prices.
