RSIN number

Upon registration with the Chamber of Commerce, all legal entities and associations, such as private limited companies, associations, foundations, general partnerships and partnerships (but not sole proprietorships, i.e. eenmanszaken), are given a Chamber of Commerce number and also an identification number for legal entities and associations (RSIN: Rechtspersonen en Samenwerkingsverbanden Informatienummer). This RSIN is used to exchange data with other government organisations, such as the Tax and Customs Administration.

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.
