B2B contacts in the Netherlands: business contact data by industry

So far from one public source: the open map data of Overture Maps (licence CDLA-Permissive-2.0). Planned are OpenStreetMap, company websites (contact page and Chamber of Commerce number), public registers of professions and regulators, and member directories of trade associations. We do not obtain bulk data from the KVK business register. We use official statistics from Statistics Netherlands (CBS) only to show the size of a market. Details for each source: data sources and methodology.

The export of a whole industry costs €239 to €469, depending on the industry; the price is on each industry page and on the pricing page. Selections by province, municipality or contact field are quoted individually. We confirm scope, data date and price in writing before you order. All prices are final prices.

Usually not without consent. Under Article 11.7 of the Dutch Telecommunications Act, unsolicited commercial email is prohibited, including towards bvs, foundations and other legal entities. Without prior consent it is only allowed to an address the company itself has published for such messages, within the purpose it attached to it (paragraph 3), or to your own customers for similar products (paragraph 4). A general info@ address on a website does not automatically qualify. Our exports contain no consent; use them for your CRM, direct mail by post, phone outreach to legal entities and market analysis.

You may call legal entities such as a bv, nv, foundation or association on business matters; the consent rule of Article 11.7(2) of the Telecommunications Act applies to natural persons. Sole traders and partnerships (vof, cv, maatschap) may only be called with their prior consent; since 1 July 2026 this also applies to existing customers. The “legal entity” column in the export helps you make that distinction. That column is only filled where the source provides the legal form; the current records have no legal form yet.

Data about legal entities is not personal data. Data about sole traders and freelancers usually is; we process it on the basis of legitimate interest (Article 6(1)(f) GDPR) and only to the extent the business publishes it itself for business purposes. If you object, we put the data on our suppression list and it is no longer included in our exports. We cannot yet check the KVK Non-Mailing Indicator (NMI), because the current records carry no KVK number; check the NMI yourself before sending advertising mail. The information under Article 14 GDPR is on information for data subjects; objections can be made via this form.

The published figures are as of 4 November 2026: 535,638 records from Overture Maps (release 2026-10-21.0), 513,153 of them with phone, email or website. Every quotation states the actual number of records and the data date of the delivery. We do not promise a fixed update interval per contact.
