Data Sources

Finland uses two official data sources. Company profile data and legal representatives are AI-parsed from the official Trade Register Extract (kaupparekisteriote) PDF document, while activity codes are fetched from the YTJ open data API.
  • PRH VIRRE (Trade Register). The Finnish Trade Register, maintained by PRH since 1896, is the primary source for Finnish entity data. PRH operates the VIRRE information service for fetching Trade Register Extracts and Articles of Association, and for searching companies by name. The Trade Register Extract PDF is AI-parsed to produce structured company data including company name, legal form, status, registered address, share capital, activity description, and legal representatives.
  • PRH ESR (Beneficial Owner Register). PRH’s separate Beneficial Owner Register (ESRServices10) provides Ultimate Beneficial Owner (UBO) data. Companies are required to register their beneficial owners with PRH. The ESR API returns structured ownership and voting rights data for natural persons who hold significant control over a company.
  • YTJ (Yritys- ja yhteisötietojärjestelmä / Finnish Business Information System). The YTJ open data API provides structured company data including official TOL (Toimialaluokitus) activity classification codes assigned by Statistics Finland. It is used to search by id and for fetching TOL codes, from which NACE and ISIC codes are derived deterministically.
Finland’s data extraction is document-based: the system fetches the official Trade Register Extract PDF from PRH’s VIRRE service and uses AI to parse structured company data from it. This means company profile and legal representatives are extracted from the same authoritative document. Legal form, status, activity descriptions, and role classifications are all AI-parsed from the extract. Activity codes (TOL) are sourced separately from the YTJ API and mapped deterministically to NACE and ISIC. UBO data comes from the separate PRH ESR register.

Company Identifiers

Query Identifiers

Business ID (Y-tunnus) Format: 1234567-8 = 7 digits + hyphen + 1 check digit. The check digit is calculated using a modulo-11 algorithm. All Finnish entities registered with PRH receive a Y-tunnus, including limited companies, partnerships, sole traders, cooperatives, foundations, and associations.

Identifiers in API Response

Once you retrieve company data, the identifiers object contains all available identifiers for that entity:

Search Capabilities

Search Performance: Use Business ID search for best performance and exact matching. Name searches query the PRH VIRRE API and may return multiple results. Name searches support Finnish, Swedish, and English company names.
ID search implementation: Searching by Business ID uses the YTJ open data API for fast, direct lookups. Name searches use the PRH VIRRE API for curated results.

Quirks & Gotchas

Mappings

Company Status

Company status is AI-parsed from the Trade Register Extract document. The AI extracts the current registration status and maps it to standardized status values.
Because status extraction is AI-parsed from the Trade Register Extract document, the exact local status text may vary. The AI maps Finnish or Swedish status descriptions to standardized values. The active boolean is derived from the statusDetails.status field.
Finland uses a variety of legal forms defined in the Trade Register. Legal form mapping is AI-enriched — the AI parser reads the legal form from the Trade Register Extract and maps it to standardized categories and ISO 20275 codes.

Key Business Forms

Partnerships

Sole Proprietorships

Cooperatives

Non-Profits & Foundations

Branch Offices & European Forms

Because legal form standardization and ISO 20275 assignment are AI-enriched, exact mappings may evolve. The local Finnish legal form name is always preserved verbatim from the Trade Register Extract.
Legal representatives are AI-parsed from the Trade Register Extract document. The AI extracts persons from sections such as “Hallitus” (Board), “Toimitusjohtaja” (CEO), and “Edustaminen” (Representation rules), and classifies them as legal representatives or other key persons.
The classification of each role as legal representative vs. other key person is AI-enriched and depends on the representation rules described in the “Edustaminen” section of the Trade Register Extract. Board members are included as legal representatives when the extract states that the board represents the company by law (e.g., “Lain nojalla yhtiötä edustaa hallitus”). Signatory rights (alone or jointly) are noted but do not affect extraction — all named signatories are included.

Representation Mode

Legal representatives include a representationMode field extracted from the “Edustaminen” (Representation) section of the Trade Register Extract:
  • { mode: "sole" }: Can sign alone (“yksin”)
  • { mode: "joint", minimumSignatories: 2 }: Must sign jointly with one other (“kaksi yhdessä” / “two jointly”)
  • { mode: "joint", minimumSignatories: 3 }: Must sign jointly with two others (“kolme yhdessä” / “three jointly”)
  • null: No signing authority explicitly stated
The field is extracted via AI parsing from Finnish-language text in the Trade Register Extract PDF.

Enrichment from Trade Register Extract

The AI parser also extracts:
  • Start dates: From person-level “Rekisteröity DD.MM.YYYY” dates or section-level registration dates
  • Nationality: From “Voimassa olevat henkilötiedot” section (e.g., “Suomen kansalainen” = FI)
  • Residence: City and country from personal details section

Other Key Persons

Auditors (“Tilintarkastajat”) and deputy board members (“Varajäsen”) are excluded from the legal representative extraction. These roles are present in the Trade Register Extract but are not currently extracted as structured data.

Shareholders

The Finnish Trade Register (PRH) does not provide structured shareholder data. Individual shareholder information is not available through the PRH VIRRE API or the Trade Register Extract. Shareholder details may appear within the Articles of Association document if the company’s bylaws reference specific shareholders or share classes, but this is not extracted as structured data.
Finland’s Trade Register does not maintain a shareholder register. Share ownership information is held privately by each company. Only the total share capital and share classes are registered with PRH.

Activity Code Mapping

The official TOL (Toimialaluokitus) code is fetched from the YTJ open data API. NACE and ISIC codes are then derived deterministically — no AI inference is involved when TOL is available.
The derivation is straightforward: TOL codes at 4 digits are identical to NACE Rev. 2 class codes (5-digit TOL codes are truncated to 4 digits, as the 5th digit is a Finnish sub-class). ISIC is then derived from NACE using the official UN correspondence table.
Deterministic mapping: When the YTJ API returns a TOL code, all activity codes (TOL, NACE, ISIC) have isAIInferred: false. If the YTJ API does not return a TOL code for a given company, the system falls back to AI inference from the Finnish activity description text (in which case isAIInferred will be true).

Data Availability

Data Availability Matrix

Legend: ✅ Available | ❌ Not Available | ⚠️ Conditionally Available | Async = Asynchronous processing (1-3 min typical)
Why UBOs are not always available: Finnish law requires a natural person to hold >25% of shares or voting rights (or exercise other significant control) to be registered as a UBO. Public companies (Oyj) have dispersed ownership below this threshold. State-owned companies have no natural person owner. Associations, foundations, and cooperatives have no “owners” in the legal sense. Sole entrepreneurs (Tmi) are not separate legal entities from their owner, so UBO registration does not apply.

Documents by Company Type

All Finnish company types have the same documents available:
Trade Register Extract Language: The Trade Register Extract is provided in Finnish (or Swedish for Swedish-registered companies). There is no English translation available from PRH. The AI parser handles Finnish/Swedish text extraction.
Both documents are always listed as available for any Finnish company. However, actual content depends on PRH having the document on file.

Example API Responses

All examples use placeholder data. Query: POST /v2/company with { "id": "<id>", "countryCode": "FI", "dataPoints": ["company", "legalRepresentatives"] }
Note: Public limited companies (Oyj) follow the same data structure as private limited companies (Oy). The incorporationDate may differ from registrationDate for older companies.
Note: Procurists (prokura holders) are included as legal representatives with the standardized role “Authorized Signatory”. Signatory rules (alone or jointly) are not modeled as separate fields.
Query with "dataPoints": ["ultimateBeneficialOwners"] for Holvi Retrieval Services Oy (2193756-4):
Note: UBO data comes from PRH’s ESR register (separate from Trade Register). Control types include ownership-of-shares (from ownershipExtent), voting-rights (from voteExtent), and significant-influence-or-control (from otherBeneficialOwnership). The residenceAddress.city is resolved from the Finnish municipality code (kuntanumero). Companies that declare no beneficial owners return an empty array. Public companies (Oyj), state-owned entities, associations, and foundations typically have no UBO data.
Query with "dataPoints": ["availableDocuments"]:
Note: Both documents are always listed as available for any Finnish company. The Trade Register Extract is the source document for AI-parsed company data.
