Data Sources

The Netherlands uses a single official registry — the KVK (Kamer van Koophandel / Chamber of Commerce) — accessed through multiple channels. Data retrieval follows a two-phase model: basic structured data from the KVK Search API, and detailed data (legal representatives, shareholders, capital, RSIN) from the HTML trade register extract via AI parsing.

KVK Search API (web-api.kvk.nl/zoeken) — Provides basic company data in structured JSON: legal name, legal form, status, address, activity description, and trade names. This is a free, fast API that returns data immediately. Used for search results and base company profile data.
KVK Trade Register Extract (Uittreksel Handelsregister) — The official HTML extract from the KVK online trade register. Contains detailed data including legal representatives (Bestuurders, Gevolmachtigden), shareholders (Aandeelhouders, Vennoten), SBI activity codes, RSIN, share capital, and employee count. This HTML is AI-parsed to extract structured data.

Two-phase data retrieval: Basic company data comes from the KVK Search API (fast, structured JSON). Detailed data (legal representatives, shareholders, capital, RSIN, SBI codes) requires fetching and AI-parsing the HTML trade register extract, which takes longer but provides comprehensive information. The trade register HTML is fetched once and reused by multiple data sources (company enrichment, legal representatives, shareholders) via document factorization.

Company Identifiers

Query Identifiers

Company Type	Source	Format	Example	Notes
All entities	KVK	8 digits (KVK number)	`53781066`	Kamer van Koophandel number — the universal Dutch business identifier

KVK Number Format: The KVK number is always exactly 8 digits. The system validates this with the regex pattern ^\d{8}$. There is no prefix, no check digit algorithm exposed to the API consumer — just 8 numeric characters.

Identifiers in API Response

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

Identifier Type	Format	Example	Found In
`KVK`	8 digits	`53781066`	All entities (from Search API)
`RSIN`	9 digits	`123456789`	Tax/fiscal identification number (from trade register extract, AI-parsed)

Identifier Casing: The system uses consistent uppercase KVK for the identifier key — not kvk or KvK. Always reference identifiers using this casing in API requests and responses.

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By KVK Number	8 digits	`53781066`	Exact	Exact match returned first (matchType: id); other results may follow
By Name	Text string	`"Philips"`	Fuzzy	Multiple results

Search Performance: Use KVK number searches for exact matching and best performance. Name searches query the KVK Search API and return multiple results. Both search types have built-in retry handling for reliability. Name search results are filtered to main establishments only (Hoofdvestiging).

Quirks & Gotchas

Quirk	Details
Two-phase data retrieval	Basic company data comes from the KVK Search API (fast, free); detailed data (legal reps, shareholders, capital) requires fetching and AI-parsing the HTML trade register extract. Legal reps and shareholders take longer to return.
KVK website access	KVK website access requires automated session handling. Search and establishment number retrieval are performed against the KVK website.
Legal form: two tiers	Onboarding mode returns 23 base legal forms from the KVK search API. Verification mode extracts the detailed form (48 values) from the trade register document. A BV that is a structuurvennootschap will show as “Besloten Vennootschap” in onboarding and “Besloten Vennootschap (blijkens statuten structuurvennootschap)” in verification.
No UBO data	Ultimate beneficial owner information is not available from the KVK API or trade register extract. The UBO register in the Netherlands is not publicly accessible.
Sole shareholders only	The KVK registers a shareholder only when a company has a single 100% holder (`Enig aandeelhouder`). A BV with two or more shareholders publishes no shareholder record at all, so `shareholders` succeeds with an empty list. See Reading an empty `shareholders` list.
Null ownership percentages	Ownership percentages are only extracted when explicitly stated in the trade register extract. `null` means “not stated”, not “0%”. The system never infers or calculates percentages.
Null nationality	Nationality is always `null` unless explicitly stated in the document. The system does not assume Dutch nationality for shareholders of Dutch companies.
SBI codes via AI	SBI 2008 codes are AI-extracted from the trade register extract HTML. NACE and ISIC are then derived deterministically (no AI). SBI 2025 codes are derived via CBS crosswalk, with LLM disambiguation for ambiguous mappings. In onboarding (no TRE), all codes are AI-inferred from the activity description.
Establishment number required	Document listing and fetching requires the `vestigingsnummer` (establishment number), which is obtained automatically before documents can be listed.
Partial document failures	The three document listing calls (extract, financials, statutes) run in parallel. If one fails, partial results are returned. Only if all three fail is an error thrown.
KVK identifier casing	The system uses consistent `KVK` casing (uppercase) for identifiers, not `kvk` or `KvK`.
Statutes listing	Deposited statutes the register has already checked for personal data are listed and can be ordered for instant download. A recently deposited deed that still contains personal data is not listed, because the register only provides it through a manual redaction request (up to about 2 working days). Core registration facts for a new company (incorporation date, legal form, capital, registered office, directors) already appear in the Trade Register Extract, but the full deed text requires that manual request.
Document delivery via email	Financial statements and statutes are ordered from KVK, delivered via email, then downloaded. This adds latency (~30 sec). Trade register extracts use a direct online flow.
AI model for legal reps	Legal representative parsing uses GPT-5.1 exclusively (no model racing). The AI extracts birth dates, start dates, roles, and authorization scope.
Company self-filtering	AI parsing sometimes includes the main company itself as a legal representative or shareholder. The system automatically filters these out by matching on KVK number.

Company Status

Company status is determined deterministically from the KVK actief boolean field. No AI inference is involved in status determination.

Local Status	English	Standardized Status	Notes
Ingeschreven	Registered	Active	`actief` = true
Uitgeschreven	Deregistered	Closed	`actief` = false

The KVK provides only a binary active/inactive status. There are no detailed closure reasons (bankruptcy, liquidation, etc.) or insolvency statuses available from the structured API. More detailed status information may occasionally be available in the trade register extract via AI parsing, but it is not systematically extracted.

Legal Forms

The Netherlands has a two-tier legal form model. The level of detail you receive depends on the mode you request.

Onboarding mode returns 23 base legal forms from the KVK search API. These are the values in the rechtsvorm field (e.g. “Besloten Vennootschap”, “Naamloze Vennootschap”, “Publiekrechtelijke Rechtspersoon”). This is a deterministic mapping with no AI involved.
Verification mode returns 48 detailed legal forms extracted from the trade register document. These are the uitgebreideRechtsvorm values (e.g. “Besloten Vennootschap (blijkens statuten structuurvennootschap)”, “Naamloze Vennootschap (beleggingsmaatschappij met veranderlijk kapitaal)”, “Publiekrechtelijke Rechtspersoon: Gemeente”). A dedicated AI parser constrained to the 48-value enum extracts the detailed form from the document.

Both tiers map to the same standardized categories and ISO 20275 codes. The difference is granularity: onboarding collapses variants into their parent form, while verification resolves the specific subtype.

Legal Representatives

Legal representatives come from the KVK trade register extract. You get a person’s name, birth date, start date, and a role that always comes from a fixed list.

A closed role list

We use a closed list of canonical roles for the Netherlands. Every role.localName you receive in the API response is guaranteed to be one of these values. The list is built on top of ISO 5009, the international standard for official organizational roles published by ISO and maintained by GLEIF. ISO 5009 covers the statutory roles defined in the Dutch Civil Code (directors, supervisory board members, liquidators, and so on). We took the Dutch entries from the ISO 5009 code list and deduplicated them into canonical roles. On top of that, we added four roles that appear on Dutch trade register extracts but are out of scope for ISO 5009 because they are based on power of attorney (volmacht) rather than corporate governance:

Gevolmachtigde and Gevolmachtigd handelsagent, registered via KVK Form 13
Procuratiehouder, a historical commercial volmacht role
Bewindvoerder, a trustee appointed during suspension of retrievals

Shareholder roles (Aandeelhouder, Vennoot, Eigenaar) are not part of this list. They live in the shareholders field of the API response.

Full role enum

The 20 canonical role values you may receive in the role.localName field. Each ISO 5009 role can map to multiple OOR codes because the code depends on the legal form of the company. For example, “Bestuurder” is KHNVNO for a BV, TK4BXG for an NV, and PPIUMW for a Stichting.

Dutch name	English	Standardized	ISO 5009 OOR codes
Bestuurder	Director	`Director`	KHNVNO (BV), TK4BXG (NV), PPIUMW (Stichting)

Bewindvoerder	Trustee (suspension of retrievals)	`Trustee`	Topograph extension (Boek 3 bewind)

Role normalization

Dutch trade register extracts sometimes use informal variants or add authority scope to a role name. We normalize these to the canonical value so you always get a predictable result.

What the extract says	What you receive
Directeur, Statutair bestuurder, Algemeen directeur	Bestuurder
Bestuurder - Alleen/zelfstandig bevoegd	Bestuurder
Bestuurder - Gezamenlijk bevoegd	Bestuurder
CEO, CFO, COO	Bestuurder
Gevolmachtigde - Beperkte volmacht	Gevolmachtigde
Gevolmachtigde - Onbeperkte volmacht	Gevolmachtigde

Signing authority (sole or joint) is kept as a separate representationMode field on the response, not mixed into the role.

Fields extracted per legal representative

Field	Dutch source term	Description
Birth date	Geboortedatum	Date of birth
Start date	Datum in functie	Date the person started in the role
Role	(from the extract)	One of the canonical values above
Name title	Mr., Mrs., Dr., etc.	Honorific prefix only

Other Key Persons

Two roles appear on Dutch trade register extracts but are not legal representatives. They are returned separately:

Dutch name	English	Standardized	ISO 5009 OOR codes
Oprichter	Founder	`Founder`	AJ86T4 (BV), 6ITGMW (NV), KLUFYX (Stichting)
Lid	Member	`Member`	1AHQJK (Vereniging)

Shareholders

Shareholders are extracted from the KVK trade register extract HTML via AI parsing, using the same HTML document as legal representatives (fetched once via document factorization).

Dutch Terms for Shareholders

Dutch Term	English	Entity Type	Found In
Aandeelhouders	Shareholders	BV, NV companies	Capital companies
Vennoten	Partners	VOF, CV partnerships	Partnerships
Eigenaar	Owner	Eenmanszaak (sole proprietorship)	Sole proprietorships

Extraction Logic

Source	When Used	Data Extracted
Trade Register Extract HTML	Always (AI-parsed)	Partners, Shareholders, Owners with names and optional share percentages

Ownership Fields

Field	Description	Source
`sharePercentage`	Ownership percentage	Only if explicitly stated in document (null if not stated)
`type`	Individual or Company	Determined from AI parsing context
`nationality`	Nationality	Only if explicitly stated (null by default — never assumes Dutch)

Critical: Ownership PercentagesShare percentages are only extracted when explicitly stated in the trade register extract (e.g., “50%”, “33,33%”). The system does not infer or calculate percentages. If no percentage is mentioned, sharePercentage is null. Do not assign 100% to each shareholder. Nationality is also null unless explicitly stated — the system does not assume Dutch nationality.

Shareholder data is available for BV/NV companies, VOF/CV partnerships (as partners), and Eenmanszaak (as owner). Stichtingen (foundations) and Verenigingen (associations) do not have shareholders.

Reading an empty `shareholders` list

Dutch law only obliges a company to register its shareholder when there is exactly one holding 100% of the shares (Enig aandeelhouder, art. 2:194 BW). A BV or NV with two or more shareholders registers nothing — the Handelsregister simply has no shareholder record for it, and neither does the Uittreksel. So for the Netherlands:

Response	Meaning
`shareholders: [ { … 100% } ]`	The company has a registered sole shareholder.
`shareholders: []` with `status: "succeeded"`	The register holds no shareholder record. Almost always a company with two or more shareholders — not a company without owners.
`shareholders` key absent	The datapoint was not requested, failed, or is still running. Check `dataStatus`.

An empty shareholders list is not a terminal node in an ownership chain. It means the Dutch register does not publish this company’s ownership, not that the chain ends. Measured across 4,322 real KVK extracts: 2,435 carry a sole shareholder and only 2 carry a multi-holder list.

When the list is empty and you need to continue the traversal:

legalRepresentatives — a Dutch holding structure is very often managed by its own parent, so a corporate Bestuurder with its own KVK number is usually the next entity up.
Trade Register History (Uittreksel Handelsregister Historie) — shows any sole-shareholder registration the company has had in the past, with start and end dates. If the history has none either, the company has never had a registered sole shareholder.
Financial Statements (Jaarrekeningen) — consolidated accounts frequently name the parent in the notes.
Deed of incorporation / statutory amendment (Akte van oprichting / Statutenwijziging) — the notarial deed names the subscribing shareholders at the time it was executed.

Activity Code Mapping

The Netherlands uses the SBI (Standaard Bedrijfsindeling) classification. SBI 2008 codes (5-digit) are extracted from the trade register extract via AI parsing. From these, NACE Rev 2 and ISIC Rev 4 codes are derived deterministically (no AI), and SBI 2025 codes are derived via the official CBS crosswalk (with LLM disambiguation for ambiguous mappings).

Company Profile (with Trade Register Extract)

TRE (AI-parsed) → SBI 2008 codes
  → truncate to 4 digits + insert dot → NACE Rev 2 (deterministic)
  → formal ISIC↔NACE mapping → ISIC Rev 4 (deterministic)
  → CBS crosswalk → SBI 2025 (1:1 resolved or LLM-disambiguated)

Classification	Source	Example	AI Inferred?
SBI 2025	Derived from SBI 2008 via CBS crosswalk	`47120`	Yes (AI-extracted from HTML + crosswalk disambiguation)
NACE Rev 2	Derived from SBI 2008 (truncate + dot)	`47.19`	No (deterministic)
ISIC Rev 4	Formal mapping from NACE	`4719`	No (deterministic)

Onboarding Profile (Search API only, no TRE)

Activity description (activiteitomschrijving)
  → LLM inference → ISIC codes
  → formal ISIC↔NACE mapping → NACE Rev 2 (deterministic)
  → CBS crosswalk → SBI 2025 (1:1 resolved or LLM-disambiguated)

Classification	Source	Example	AI Inferred?
SBI 2025	Derived from NACE via CBS crosswalk	`64110`	Yes
NACE Rev 2	Derived from ISIC (formal mapping)	`64.11`	Yes (source ISIC is AI-inferred)
ISIC Rev 4	LLM-inferred from activity description	`6411`	Yes

Deterministic vs. AI-inferred: When the trade register extract is available (company profile), NACE and ISIC are derived deterministically from SBI 2008 codes (isAIInferred: false). SBI 2025 codes use the CBS crosswalk — 1:1 mappings are resolved automatically, ambiguous mappings (multiple SBI 2025 candidates for one NACE code) are disambiguated by an LLM using the company’s activity description. When only the search API is available (onboarding profile), all codes are AI-inferred from the activity description text.

Trade Register Extract: The Uittreksel is an HTML document fetched from the KVK website and converted to PDF for delivery. The HTML content is AI-parsed to extract structured data.

Document Delivery Methods: The trade register extract uses a direct online flow (fast, ~30 sec). Financial statements and statutes use a mail flow: the document is ordered from KVK, delivered via email, then downloaded and saved. This adds latency but is the only retrieval method available for these document types.

Document Listing: Documents are listed via three parallel KVK API calls: (1) trade register extract availability, (2) financial statements, (3) statutes. If one source fails, partial results are still returned. Only if all three fail is an error thrown.
