Doing business safely with the KVK APIs

Why do things the hard way? Avoid searching, checking and retyping your customers' data. Think of trade name, address details, Chamber of Commerce number and more. Create a link with the KVK API (Application Programming Interface). The KVK API provides you with a lot of convenience and prevents unnecessary mistakes.

Available APIs

KVK Handelsregister Zoeken

This API allows you to search companies listed in the Business Register. You can search using KVK number, RSIN, branch number, business name, address or town/city. You can then use another API, such as API basisprofiel or API vestigingsprofiel, to request data.

KVK Handelsregister Basisprofiel

This API allows you to request basic information on companies from the Business Register, such as their business activity, owner details, head office details and a link to a list of offices. Selection is based on the KVK number.

KVK Handelsregister Vestigingsprofiel

This API allows you to request specific information on companies from the Business Register, such as their basic information, business activities and physical and postal address. Selection is based on the ‘vestigingsnummer’.

KVK Handelsregister Naamgeving

With this API you request name data from companies from the Business Register. For example, statutory name, trade names and non-commercial name. You search by KVK number.
