FAQ

Each year, there are circa 350,000 new registrations and 2,300,000 changes in the entire Business Register. Nearly half of those are changes in the details of a branch office, and a third changes in officials.  

When you start your subscription, you receive a list of KVK numbers. This is the result of the population you have assembled, based on population criteria. You use this list (the population) to determine for which KVK numbers you want to order a product. To avoid an overload, the moment for ordering products is usually decided in consultation.
