Mutatieservice

If you have a KMS subscription for all entries in the Business Register, you will receive the "Nieuwe Inschrijving" and "Gewijzigde Inschrijving" signals. 

• Check the KVK Mutation Service agreement on page 5 to see if both signals are selected. 
• When a new entry is registered, we deliver the "Nieuwe Inschrijving" and "Gewijzigde Inschrijving" signals. 
• When a new KVK number is registered, you will receive both signals. 
• When you make a change to the KVK number (the entry), only the "Gewijzigde Inschrijving" signal is delivered.

After a mutation or change has taken place in the Business Register, you will receive a notification within 15 minutes.

The date you join is the start date. The annual contract begins on that date. Do you wish to renew? Then you will receive the next invoice on the same date in the following year.

Saving up from previous years or carrying over to subsequent years is not possible.

• Generic information: all current branches of the KVK registration. 
• Specific information: provides an indication of what has changed in the relevant KVK registration.

The KVK Mutatieservice catalogue indicates which information (generic and specific) is delivered in a signal.

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 "Vestigingen" and "Deponeringen" data blocks will not show any fields if no change has occurred. The "Onderneming", "Eigenaar", and "Functionarissen" 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 data item. After receiving this notification, you can decide to retrieve the updated data via the KVK API or the KVK Dataservice.

We provide real-time updates on changes to the public data in the Business Register. The exception to this is the Communication Data collection, because the phone and fax numbers are not public. Nor do we provide the email address or website in the signal message.
