Extract contains RSIN number
You can find the RSIN of a business in the KVK Extract (only in Dutch). Businesses or organisations sometimes also state their RSIN on their own website. Note: sole proprietorships do not have an RSIN.
What is the RSIN used for?
The RSIN is used to link data between various basic registrations, such as the land register and the municipal personal records database (BRP: Basisregistratie Personen). Accordingly, you do not have to provide your details on multiple occasions. For instance, you no longer need to register separately with the Dutch Tax and Customs Administration.
