Finland Company Check — PRH/YTJ Register & Financials

Give this Actor a list of Finnish companies — by Business ID (Y-tunnus), VAT number (FI…) or name — and it returns one row per entry, including the ones that were not found. Every row is built from the official open APIs of the Finnish Patent and Registration Office (PRH):

• the Business Information System (YTJ): name, legal form, address, industry (TOL), status — bankruptcy, restructuring, liquidation, ceased — and the tax registers: prepayment register (ennakkoperintärekisteri), VAT register and employer register, each with its date;
• the Trade Register notices: a registered loss of share capital, filed financial statements, debt adjustment — plus the latest ten notices of the company;
• the digital financial statements (XBRL): revenue or gross profit, operating profit, net result, equity, liabilities, total assets and cash, for the latest year and the year before.

No scraping, no proxy, no browser.

Built for supplier and customer onboarding (KYB), credit and collections teams who need to know whether a counterparty is still trading, subcontractor checks under the Finnish Contractor's Obligations Act, and periodic re-checks of a customer or supplier book.

Option	Default	Meaning
companies	—	Business IDs, VAT numbers or names; also {"businessId": …} or {"name": …}
maxMatchesPerName	1	Rows per name query, best match first (1–10)
includeNotices	true	Register notices and the flags derived from them
includeFinancials	true	Key figures from digital financial statements
includeRawRecord	false	The untouched PRH record under raw, with Finnish code values
requestIntervalSeconds	1.0	Spacing between requests (minimum 0.5)

0112038-9, 01120389, 112038-9 and FI01120389 all work. Check digits are validated before querying — a mistyped Business ID comes back as a row with error, not as a false "not found". Finnish personal identity codes are recognised and never searched. Duplicates in your list are checked once.

Name queries are matched strictly. The register's own name search also returns similar names. This Actor only accepts a company with a registered name — current, parallel, auxiliary or former — that contains every word of your query, ranks exact matches and active companies first, and says how and on which name it matched. If nothing qualifies, the row is not_found and note lists the closest names the register suggested.

Speed

PRH temporarily blocks clients that query its open APIs too fast. This Actor spaces its requests (one per second by default, shared across all threads) and pauses on its own if PRH signals a limit, so a run waits out a block instead of failing.

Measured 12 October 2026: 268 entries in about 10 minutes (617 requests, no limit hit), with notices and financial statements. A company takes one request, plus one or two for limited companies when financial statements are looked up — plan roughly 40 minutes for 1,000 companies.

Limits, honestly

• Digital financial statements only. PRH publishes figures only from statements that were filed in XBRL form — 11,765 companies for financial years ending 31 December 2025 (as of 12 October 2026); in a test list of 220 companies in bankruptcy, restructuring or liquidation, about one in ten had them. For every other company financials stays empty; lastAccountsFiledOn still shows when statements were registered. Listed groups reporting under IFRS are not in this service.
• No people. PRH's open data contains no board members, managing directors or owners.
• The tax registers show registration, not tax compliance. The Contractor's Obligations Act also asks for a tax debt certificate and pension insurance details, which are not open data.
• annual_accounts_overdue is a heuristic: an Oy or Oyj registered more than 30 months ago without financial statements registered in the last 21 months (the deadline is eight months after the end of the financial year). It is null where it does not apply.
• This is not a credit report. It states what the official registers say on the day you ask.

Pricing

Pay per event:

Event	What it covers
actor-start	once per run
company-check	one company row — including "not found"

Rows with an error are free: a wrong check digit or a source that did not answer is never billed. Notices and financial statements are included in the company price. A spending limit you set on the run is respected — the run stops cleanly when it is reached.

Suomeksi

Tarkista suomalaiset yritykset PRH:n ja YTJ:n avoimesta datasta. Liitä lista Y-tunnuksia, ALV-numeroita tai toiminimiä. Actor tarkistaa Y-tunnuksen tarkistusmerkin ja palauttaa yhden rivin jokaista hakua kohden, myös silloin kun yritystä ei löydy:

• tila — toiminnassa, konkurssi, yrityssaneeraus, selvitystila, lopettanut tai poistettu rekisteristä;
• varoitusmerkinnät kaupparekisteri-ilmoituksista: osakepääoman menetys, velkajärjestely ja viimeisin rekisteröity tilinpäätös;
• verohallinnon rekisterit — ennakkoperintärekisteri, arvonlisäverovelvollisten rekisteri ja työnantajarekisteri päivämäärineen;
• tilinpäätöstiedot digitaalisesti ilmoitetuista tilinpäätöksistä: liikevaihto tai bruttotulos, liikevoitto, tilikauden tulos, oma pääoma, vieras pääoma ja taseen loppusumma kahdelta tilikaudelta.

Tiedot haetaan vain PRH:n avoimista rajapinnoista — ilman välityspalvelinta ja ilman sivujen kaapimista. Rivit, joiden Y-tunnus on virheellinen, ovat maksuttomia.
