Zoeken API

Yes. These are all search options in the API KVK Handelsregister Zoeken:

• Chamber of Commerce number
• RSIN
• Location number
• Name
• Street and place
• Postal code and house number (new)

Postal code and house number are not shown by default in the search result, unless they are searched for.

The Zoeken API only allows you to look up companies. You get the information with the other two APIs. The API KVK Handelsregister Basisprofiel works with the Chamber of Commerce number found. The API KVK Handelsregister Vestigingsprofiel works with the location number found.
