Finland Business Registry (YTJ & PRH Trade Register) & Open Business Companies Data: Y-tunnus (Finnish Business ID), Official Portals & Master Data

What You Need to Know at a Glance: Finland Business Registry & Company Master Data (YTJ & PRH Trade Register)

The statutory backbone for company register search in Finland is YTJ Business Information System & PRH Trade Register (Kaupparekisteri), keyed by each organization’s Y-tunnus (Finnish Business ID). Around that core register, Finland’s institutional data landscape comprises 10 verified official sources managed by Finnish Patent and Registration Office / Finnish Tax Administration, Finnish Patent and Registration Office, Digital and Population Data Services Agency / Suomi.fi, Finnish public procurement advisory unit / HILMA. Primary legal-entity lookup routes include FIN-FSA registers (Finnish Financial Supervisory Authority).

Complementing the primary register at YTJ & PRH Trade Register, Finland maintains specialized public portals for open data catalogues and statistical business frames through Suomi.fi Avoindata catalogue (Digital and Population Data Services Agency / Suomi.fi); financial supervision, capital-market disclosures, and LEI records from Finnish Competition and Consumer Authority (Finnish Competition and Consumer Authority) and GLEIF LEI records for Finland (GLEIF); public procurement notices, official gazettes, and intellectual-property registers such as HILMA public procurement guidance (Finnish public procurement advisory unit / HILMA) and YTJ / PRH open data (Finnish Patent and Registration Office / Finnish Tax Administration).

How the Official Finland Business Registry (YTJ & PRH Trade Register) & Public Data Ecosystem Work

Finland is one of the stronger European jurisdictions for official company-data work because the YTJ/PRH stack is explicit about open data, API use, daily updates, basic company details and important exclusions. That makes Finland a good benchmark for what a serious open-company-data article should do: start with the official register and API evidence, then keep every enrichment layer separate.

Quick source answer: For Finland, start with the Business Information System/YTJ and official PRH/statistics/open-data routes, then check which fields are available, downloadable or reusable. This guide answers the registry-source question first, then explains source limits, reuse conditions and where normalization adds value.

The practical mistake is to say that Finland has “all company data” available in one reusable file. The safer and more useful answer is more precise. YTJ/PRH open data is the primary machine-readable route. YTJ company search and PRH online services support manual verification and document/product routing. Suomi.fi Avoindata helps discover wider public-sector datasets. HILMA, PRH intellectual-property services, FIN-FSA, FCCA and GLEIF add supplier, IP, regulated-entity, competition and LEI context.

Registry and API coverage: the YTJ/PRH open-data route provides the strongest source evidence. It supports basic company details, register-membership details and digital financial-statement information. The official page also states that the data are digital and updated once a day. That supports a high-confidence API and update-cadence claim, not a claim that every Finnish corporate document or contact field is freely reusable.

Known exclusions: YTJ/PRH open data does not provide email addresses or phone numbers. It also excludes private traders and certain public-sector or tax partnership categories. A derived Finland dataset should therefore expose source coverage and exclusions clearly instead of hiding them behind a generic “complete database” label.

Official Finland Business Registry, Company Data API & Master Data Portals (10 Verified Sources)

Core Corporate Registry, Entity Lookup & Statutory Filings

FIN-FSA registers — Finnish Financial Supervisory Authority

Data & Access: sector-specific registers for supervised, authorised or notified financial-sector entities

Terms & Operational Scope: regulator-source terms apply; store regulatory category, authority and access date separately. sector-specific and not a complete company register; some lists may include foreign or cross-border entities

National Open Data Portals, Bulk Feeds & Statistical Agencies

Suomi.fi Avoindata catalogue — Digital and Population Data Services Agency / Suomi.fi

Data & Access: national open-data catalogue for discovering Finnish datasets and API metadata

Terms & Operational Scope: dataset-specific licences apply; the catalogue is discovery evidence, not a blanket reuse approval. company identity still belongs in YTJ/PRH evidence; catalogue metadata must not be treated as field-level permission

Central Bank, Financial Supervision, Capital Markets & LEI

Finnish Competition and Consumer Authority — Finnish Competition and Consumer Authority

Data & Access: competition, merger-control, consumer and advocacy information from the national authority

Terms & Operational Scope: decision and authority-context source; case reuse needs decision-specific provenance. case-driven coverage and not a register of all companies

GLEIF LEI records for Finland — GLEIF

Data & Access: public JSON API for LEI-bearing Finnish entities

Terms & Operational Scope: GLEIF API terms and attribution apply; use as enrichment and identifier cross-check only. partial coverage limited to entities that have LEIs

Public Procurement & Intellectual Property Registers

HILMA public procurement guidance — Finnish public procurement advisory unit / HILMA

Data & Access: official guidance and route to the free electronic public-procurement notice channel

Terms & Operational Scope: procurement-notice and guidance terms apply; cite notice provenance and do not infer whole-company coverage. procurement is event-based and supplier-biased; it does not represent all Finnish companies

YTJ / PRH open data — Finnish Patent and Registration Office / Finnish Tax Administration

Data & Access: free official interface/API for company details and digital financial statement information

Terms & Operational Scope: official open-data route; preserve source, access date, update date, field scope and no-endorsement wording. email addresses and phone numbers are not available; private traders and some public-sector or tax partnership categories are excluded

YTJ company and organisation search — Finnish Patent and Registration Office / Finnish Tax Administration

Data & Access: free public search for companies, organisations and associations by Business ID or name

Terms & Operational Scope: manual verification route; automated reuse should follow YTJ rules and source-specific terms. public search shows current details and selected previous details; occasional search is not the same as all-fields bulk reuse

PRH Finnish Trade Register — Finnish Patent and Registration Office

Data & Access: official Trade Register route for legal-register context, filings, register notices and guidance

Terms & Operational Scope: official register source; documents, extracts and detailed products can have separate fees and terms. register guidance is not a blanket permission to republish every document or personal-data field

PRH online services and Virre — Finnish Patent and Registration Office

Data & Access: official online-service overview for Virre, YTJ search, extracts, payments and other PRH services

Terms & Operational Scope: service-specific terms and fees apply; use as route evidence for manual products and paid documents. basic details and some extracts are free, but financial statements, articles of association and other products can be paid

PRH patents and IP services — Finnish Patent and Registration Office

Data & Access: official IP guidance and patent route for rights-owner and invention context

Terms & Operational Scope: IP records and right-owner data need source-specific terms and matching confidence. IP ownership can differ from company identity and does not prove operating status by itself

Operational Scope, Access Workflows & What Is Missing from Public Finland Registry Records

Manual search and documents: YTJ company search is free and useful for Business ID lookup, register membership, legal name, company form, registered office and main line of business. PRH online services and Virre add extract and document workflows. Some products are free, but financial statements, articles of association and other documents can involve fees or product-specific terms.

Enrichment layers: HILMA covers procurement notices and supplier events; PRH IP pages route patent and rights-owner context; FIN-FSA registers cover supervised financial entities; FCCA covers competition and consumer authority context; GLEIF covers LEI-bearing entities. None of these sources replaces the YTJ/PRH company core.

Update risk: YTJ/PRH open data, YTJ search, PRH document products, procurement notices, IP records, regulator records, competition cases and LEI records update on different schedules. A trustworthy dataset should carry source-specific timestamps rather than one generic Finland freshness date.

API and open-data route: start with YTJ/PRH open data when the project needs repeatable ingestion. Store the endpoint or interface route, access date, update cadence, coverage exclusions, field list, parser version and the fact that contact fields are absent. Use daily update semantics only for the data layer that actually carries that promise.

Manual verification: use YTJ company and organisation search for individual Business ID checks, disputed-name resolution and quick inspection. Manual search is valuable for validation, but it should not be described as an unrestricted bulk route.

Register and document products: use PRH Trade Register and PRH online services to understand filings, extracts, Virre products, financial statements and articles of association. When a product is paid or document-specific, store the product route and fee/terms note separately from open API fields.

• Best official starting point: YTJ / PRH open data, because it is free, official, API-oriented, updated daily and clear about missing email and phone fields.
• Best manual verification route: YTJ company and organisation search, which supports free searches by Business ID and exposes core current company details.
• Best register context: PRH Trade Register and PRH online services/Virre explain filings, extracts, paid products and service boundaries.
• Best enrichment stack: Suomi.fi Avoindata, HILMA, PRH IP, FIN-FSA, FCCA and GLEIF add public-sector dataset discovery, procurement, IP, regulator, competition and LEI signals.
• Contact-data caution: Finnish public company data is not consent for email, phone, lead-list or sales-prospecting contact enrichment.
• Entity core: Business ID, legal name, normalized name, company form, status, registered office, main line of business, country, source URL, access date and confidence.
• YTJ/PRH open-data layer: endpoint or interface route, field list, update cadence, excluded categories, financial-statement availability and parser version.
• Manual verification layer: YTJ search URL, viewed date, current detail flags, previous-detail availability and reviewer confidence.

Frequently Asked Questions: Finland Business Registry (YTJ & PRH Trade Register) & Company Data

What is the best official source for Finland company data?

Start with YTJ / PRH open data. It is the clearest official route for free company details, daily updates and machine-readable planning, while also stating important exclusions.

Does Finland provide an official API or open-data route?

Yes. The YTJ/PRH open-data route supports interface/API use for company details and digital financial-statement information. Production use should still preserve source terms, access dates, update cadence, field scope and exclusions.

Does YTJ/PRH open data include emails and phone numbers?

No. The official open-data page states that email addresses and phone numbers are not available. Contact-data enrichment requires a separate lawful-basis and suppression workflow.

Is YTJ company search the same as bulk access?

No. It is a free public search route for individual verification. It is valuable for validation and record lookup, but it should not be described as an unrestricted bulk database.

Can beneficial ownership be published as open company data?

Not automatically. Beneficial ownership involves natural-person data and AML purpose limits, so it needs special review before commercial publication or ingestion.

Why use CompaniesData for Finland?

Finland has strong official sources, but useful commercial data still requires normalization, source provenance, API/manual route separation, enrichment matching and privacy controls. CompaniesData packages those layers into a practical dataset.
