Yes, that is possible. When multiple changes are made in the Business Register within one submission, a single notification message with multiple modified details is generated.

You cannot expand or collapse the data blocks. If there has been a change in a record, the fields within the data block will be displayed. The "Branches" and "Deposits" data blocks will not show any fields if no change has occurred. The "Business", "Owner", and "Officers" data blocks always display the underlying fields, even if no change has been made. The J/N indicator shows which records have been changed.

No, you only receive a notification if there has been a change in a public record. After receiving this notification, you can decide to retrieve the updated data via the KVK API or the KVK Dataservice.

We provide the public data that changes in the Business Register in real-time. The exception to this is the Communication Data collection because the phone number and fax number is not public. In addition, we provide the e-mail address and website is not included in the signal message.

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.

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.
