Finnish Company Name Search (PRH Business Information System)

prhytj/search-finnish-companies

Searches the Finnish Trade Register by company name and returns the matching companies: business ID (Y-tunnus), registered and auxiliary names with their dates, main line of business (in Finnish, Swedish and English), company form, registered entries, addresses and status, plus the total number of matches. A name nobody holds returns an empty list. A page holds up to 100 companies and a common name returns a few hundred kilobytes, so add a location to narrow it; page through the rest. Looking up a known business ID is cheaper: prhytj/company-by-business-id.
