Finland Company Register — YTJ / PRH Lookup

Look up Finnish companies by name or business ID. Legal form, industry, addresses, current and former names, and which registers they are entered in. From the official YTJ open data, no key required.

What it does

YTJ is the shared business information system of PRH and the Finnish Tax Administration. It is open data, published in a shape built for Finnish systems: every description arrives in three languages at once, names carry validity dates rather than a current flag, addresses hide the city inside a nested multilingual list, and statuses are bare numeric codes.

This Actor flattens that into one row per query with 31 fields, in English where the source provides an English description.

What you get

31 fields per row, including business_id, name, legal_form, main_business_line, street_city, registered_on, active_registrations, situations, total_matches, name_match_score and matched_by.

The table view shows 12 of them; all 31 are in the JSON, CSV and Excel downloads.

active_registrations counts which registers the company is actually entered in — trade register, VAT, prepayment, employer. A company can exist and be registered for none of them.

Input

Field	Meaning
businessIds	Finnish business IDs, for example 0112038-9.

  "businessIds": ["0112038-9", "1927400-1"],

There is no start fee and no per-row dataset fee.

What it does not do

No financials and no officers. YTJ covers company identity, registrations and addresses. Annual accounts and board members are not in the open data.

Fragments of names do not work well. KONE Oyj finds KONE. Kone matches eleven thousand machine shops, because the word is common in Finnish. total_matches reports how many, and the row returns the best one.

Descriptions are English only where the source has English. YTJ publishes Finnish, Swedish and English versions of most descriptions; English is used when present and the Finnish original when it is not.

situations is usually empty. It carries bankruptcy and restructuring entries, which most companies do not have.

Notes

Send business IDs where available. They are exact and remove the ambiguity entirely.

Sort by total_matches descending to find the queries that were too vague to trust.

no_current_name means every name on file has an end date, which usually indicates a dissolved company.

Support

Open the Issues tab with the exact query and the matched_by, total_matches and issues values from the row.
