Search companies by industry (NACE code), country, region and size in official E
Search companies by industry (NACE code), country, region and size in official European business registers: France (Sirene), Norway (Brønnøysund), Finland (PRH/YTJ). Give one NACE code, Rev. 2 or Rev. 2.1: it is translated into each registry's own classification with the official correspondence tables (Eurostat, INSEE NAF, Statistics Finland TOL, SSB SN2025), and only companies whose main activity matches come back, up to 25, with registry ID, status, both NACE codes, local code, size band, address, licence and attribution. No sole traders. Charged only if a company is found. 20 free calls/day per IP with header X-Free-Trial: 1.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
