I receive unwanted email, what can I do about it?

If you receive unwanted emails (spam), please contact the sender to raise the issue. If this does not resolve the matter, you can lodge a complaint with the Netherlands Authority for Consumers and Markets ACM. They also offer tips on how to avoid receiving spam. Businesses or organisations may only send you commercial emails if you have given your prior consent. There is, however, an exception to this rule. Businesses or organisations may send unsolicited messages about similar services or products to customers to whom they have previously sold a product or service. They may do so without your consent, provided they make it clear how you can opt out of receiving such advertising. Are you bothered by annoying emails? Then take a look at tips for dealing with unwanted post, emails or phone calls.

Why am I required to register my phone number upon registration?

The Business Register Act 2007 (Handelsregisterwet) stipulates that KVK must register the telephone number of every business owner or managing director. The telephone number is not publicly available. Only KVK and organisations authorised to do so, such as the Netherlands Tax Administration or a civil-law notary, can view your telephone number and contact you. Are you bothered by annoying phone calls? Read here what you can do about it.

My details are listed on several online channels. How can I get them removed?

You can change your business details in the phone guide and Yellow Pages (Telefoongids & Gouden Gids) yourself online, via detelefoongids.nl. Open your entry on detelefoongids.nl, click on your name to see the details. Then click the 'Manage your company data free of charge' link (in Dutch: 'Beheer gratis jouw bedrijfsgegevens'). To request removal of your details by Google, use this form. To request removal from other websites, you can use the Dutch Data Protection Authority (Autoriteit Persoonsgegevens, AP) sample letters (in Dutch). On social media, manage the visibility of your details through your settings.

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

If you do not want companies to use your business or organisation’s address for advertising mail or door-to-door sales, please let KVK know. Read below to find out how to do this.

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 turn protection 'on' or 'off'

Is the protection enabled? If so, your business’s KVK extract will state that your address must not be used for advertising post. Nor may the address be used for door-to-door sales. It is a sort of ‘digital do-not-disturb sticker’. We also refer to this as an NMI (Non-Mailing Indicator).

If a business or organisation contacts you anyway, you can refer to the ‘digital “no-advertising” sticker’. You can use (Dutch) letter templates preprared by the Dutch Data Protection Authority for this purpose.

Hiding your visiting address

Activating the NMI is not the same as completely shielding your visiting address. When you hide the visiting address of your business or organisation, the address is no longer visible to others who view details in the Business Register.

Doing business safely with 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 telephone number listed in the Business Register is not public information. Only authorised organisations, such as the Netherlands Tax Administration or civil-law notaries, can see your telephone 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.
