KVK Mutatieservice (KMS)

Receive 24/7 alerts about changes in the Business Register. You specify for which changes you want to receive an alert. For example: SBI, number of employed persons, municipality, or province.

How does it work?

  • You immediately receive an alert when something changes in the Business Register. 
  • You receive alerts about changes in the Business Register 24/7. 
  • You determine in advance for which target group you want to receive alerts. 
  • Extensive choice of registration types for which you want to receive alerts (such as SBI, number of employed persons, municipality, and province). 
  • With the alerts, you retrieve reliable and up-to-date data from the Business Register via a different API. 
  • You do not need to take immediate action when you receive an alert. Save the change and retrieve the most recent information later.

Connect 

  • Determine which signals you wish to receive. View the KMS catalog (in Dutch) for all signals. 
  • To connect KMS, you need an API subscription. Do you not have one yet? Arrange this first. 
  • Market parties connect directly to the API (JSON). 
  • Government bodies preferably connect via Digilevering through Logius (XML).

Frequently asked questions about KMS

Every year, 350,000 new registrations and 2,300,000 changes are processed in the Business Register. Half of these are changes of establishment. A third are changes of officials.

At the start of the subscription, you will receive a list of KVK numbers. This is the result of the desired population that you have compiled using population criteria. With this list (the population), you can then determine for which KVK numbers a product must be purchased. In order to prevent overload, it is agreed in consultation at what time the products can best be purchased.

That depends on how you want to connect KMS. If you are already using APIs or an automated connection, the impact is limited. Do you work manually or with exports? Then there is more work to be done. Do you want real-time processing of mutation data and full automation? Then it will be a major project.
