Protect your address from advertising and door-to-door sales

Do you not want other businesses and organisations to use your organisation's address for sales or advertising purposes? Report this to KVK. Anyone who requests an extract of your details from KVK will see whether they are allowed to use your address for advertising purposes.

How to protect your address

Send an email to handelsregistermail@kvk.nl. Please include the following information in the email:

  • company name or KVK number
  • the name of the person who is officially authorised to register, change or deregister your company or organisation in the Business Register
  • whether you want to enable or disable protection

Is the protection enabled? Then anyone who requests a KVK Business Register Extract of your company will see that your address may not be used for advertising.

If you are approached in spite of this, you can point out to the company that they are required by law to observe your wishes. You can use (Dutch) letter templates preprared by the Dutch Data Protection Authority.

The Business Register

Businesses use the information from the Business Register to check the details of your company or to find new customers. You yourself can also do this, for example by ordering a KVK Business Register Extract.

Good to know

Your phone number listed in the Business Register is not public data. Only organisations that have permission to do so, such as the Netherlands Tax Administration or civil-law notaries, can see your phone number.

No more unwanted mail?

Protecting your address from advertising and door-to-door sales – also known as NMI (Non Mailing Indicator) – means that others will have less chance of finding your address. For example, Google does not include businesses that protect their address in Google Maps.

Protecting your address does not guarantee that no one will come to your door. Businesses and organisations can also find address details in other places, such as address directories and websites. And businesses can of course also reach you by email or telephone. So get started with more tips against unwanted mail, emails or phone calls.

Frequently asked questions

Companies are only allowed to send you commercial email if you have given them your consent. There is an exception to this rule. If the company has sold a service or product to you (i.e. you are an existing customer), they may email you about similar services or products without asking your permission. 


If you receive unwanted digital mail (spam), ask the sender to stop. If they do not stop, you can lodge a complaint with the Netherlands Authority for Consumers and Markets ACM. They also offer tips on how to avoid receiving spam.

The Commercial Register Act 2007 (Handelsregisterwet) states that KVK must register the phone number of every entrepreneur. The phone number is not public. Only KVK and authorised organisations, such as the Netherlands Tax Administration or a civil-law notary, can see your phone number and contact you.
