An Apify Actor that scrapes the Dutch Chamber of Commerce (Kamer van Koophandel / KVK) Handelsregister (Trade Register). Search by company name or look up specific KVK numbers, with full control over filters, result source, and rate limiting.

What it does

• Search for companies by name or other identifiers
• Look up one or more KVK numbers directly (batch mode)
• Filter by registration status, vestiging type, and trade name type
• Choose between all results, Handelsregister only, or Advies & Inspiratie only
• Handles pagination automatically
• Rate-limited by default to avoid IP blocks — works without a proxy for moderate volumes

Input

Search fields

Filters

Important: inschrijvingsstatus, vestigingType, and handelsnamen are Handelsregister-specific filters. When site is set to corporate (Advies & Inspiratie only), these filters have no effect and will return empty results if set. Leave them at their defaults or clear them when using corporate.

Performance

Example — search by company name

{
"searchQuery":"Software",
"maxPages":2,
"pageSize":20
}

Example — direct KVK number lookup (batch)

{
"kvkNumbers":["42009680","82871612"],
"inschrijvingsstatus":["ingeschreven"],
"site":"handelsregister"
}

Example — include deregistered companies too

{
"searchQuery":"Bakkerij",
"inschrijvingsstatus":["ingeschreven","uitgeschreven"],
"vestigingType":["hoofdvestigingen","rechtspersonen"]
}

Example — Advies & Inspiratie only (corporate)

Use only Search, Result source, Language, page size, and performance options. Leave Handelsregister filters empty / default.

{
"searchQuery":"KPN",
"site":"corporate",
"language":"nl",
"pageSize":10,
"maxPages":1
}

See Output → Advies & Inspiratie for the dataset JSON shape.

Example — full Handelsregister filter set

{
"kvkNumbers":["42009680"],
"pageSize":10,
"language":"nl",
"site":"kvk2014",
"inschrijvingsstatus":["ingeschreven","uitgeschreven"],
"vestigingType":["hoofdvestigingen","nevenvestigingen","rechtspersonen","overig"],
"handelsnamen":["bestaandeHandelsnamen"],
"maxRequestsPerMinute":120
}

Output

The dataset stores one JSON object per search hit. The shape depends on whether the hit is from the Handelsregister or from Advies & Inspiratie (KVK website articles). With site set to All results (kvk2014), you may get both shapes in the same run.

Handelsregister record

No resultType field — normalized company / establishment data:

{
"id":"e027319e-bddf-4982-ac35-ed5cd4a96222",
"kvkNumber":"82871612",
"establishmentNumber":"000049081160",
"name":"Software Buddy",
"legalFormCode":"EMZ",
"legalForm":"Eenmanszaak",
"isActive":true,
"isEstablishment":true,
"registrationType":"Hoofdvestiging",
"visitingAddress":{
"street":"Kloosterlaan",
"houseNumber":"33",
"houseNumberAddition":null,
"postalCode":"1216NH",
"city":"Hilversum"
},
"postalAddress":{
"street":null,
"houseNumber":null,
"houseNumberAddition":null,
"postalCode":null,

},
"activityDescription":"Ontwikkelen, produceren en uitgeven van software...",
"currentTradeNames":["Software Buddy","Maxtrada"],
"formerTradeNames":["Codemap NL"],
"statutoryName":null,
"source":"Actueel"
}

Advies & Inspiratie (site: corporate, or mixed under kvk2014)

When KVK’s search returns Advies & Inspiratie hits (crawler-public), each row looks like this (excerpt — full content can be very long):

{
"resultType":"advies-en-inspiratie",
"id":"4d4ee662-5cda-4b78-8545-52649a21c610",
"title":"Zo help je een werknemer met geldzorgen | KVK",
"url":"https://www.kvk.nl/personeel/zo-help-je-een-werknemer-met-geldzorgen/",
"description":"Vermoed je dat je werknemers geldzorgen hebben of vragen ze om een voorschot van salaris? Weet wat je als werkgever kunt doen om je werknemers te ondersteunen.",
"content":"Zo help je een werknemer met geldzorgen Esther Riphagen ...",
"language":"nl"
}

Note on multiple records per KVK number

A single KVK number can return more than one record. For example, a company may have both a Rechtspersoon (legal entity) and one or more Vestiging (establishment) entries — each as a separate dataset item sharing the same kvkNumber but with a different id and establishmentNumber.

Rate limiting

Without a proxy, all requests go through the same IP. The default of 120 requests/minute is safe for most use cases. If you hit 429 errors:

• Lower maxRequestsPerMinute (try 60)
• Enable a proxy via proxyConfiguration

With a proxy, session rotation automatically handles rate-limited requests by switching IP.

Pay Per Event Billing

This Actor uses Apify's Pay Per Event pricing — you only pay for what actually runs.

You can cap total spend in the Apify Console when starting a run via Max total charge (USD) or Max paid dataset items.
