You will receive a Chamber of Commerce number (KvK-nummer) when you register in the trade register of the Chamber of Commerce (KvK). The costs are €50,- once. After you have registered with the Chamber of Commerce, you will automatically receive a VAT number assigned by the Belastingdienst (Dutch Tax Authority). To be able to insure yourself as a freelancer you need to have a Chamber of Commerce number. As soon as you start freelancing more regularly, you may be legally obliged to register with the Chamber of Commerce.

However, a VAT number can also be granted to companies that do not have to register with the Chamber of Commerce. You can request a VAT number for this free of charge using the 'Opgaaf Startende Onderneming' form. If the Tax Authorities approve your application, the VAT number will then be provided to you by post (in combination with the log-in details for making the VAT declarations online).
