Would you prefer companies not to use your business or organisation’s address for advertising mail or door-to-door sales? You can state this by making a note in the Business Register. Read on to find out how it works.
How can you prevent advertising being sent to your business address?
If you want to receive less advertising post or door-to-door sales, you can register for the non-mailing indicator (NMI) with KVK. This is a kind of ‘do not disturb’ sticker in the Business Register. By registering for the NMI, you indicate that companies are not allowed to use your address details for advertising post or door-to-door sales.
If the NMI is active, your address will still appear on your company or organisation’s KVK extract. However, it will show that others may not use your address for junk mail or door-to-door sales. If a company or organisation still contacts you, you can refer them to the NMI. You can use sample letters from the Dutch Data Protection Authority for this purpose. This letter is in Dutch.
Please note, the NMI makes it harder for others to find your address. For example, Google does not include businesses that protect their address using the NMI in Google Maps. This therefore also has disadvantages in terms of how easily customers can find you.
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
- say whether you want to turn NMI protection 'on' or 'off'
Does the NMI ensure that you will never receive any more advertising?
No. Organisations can still find your address in other ways, such as via websites or public address lists. And businesses can also contact you by email or phone. If you want to make that harder, take a look at our tips on how to deal with unwanted post, emails, or phone calls.
Does the NMI make your address invisible in the Business Register?
No. If you want to do that, you will need to shield your visiting address. With the NMI, your address will still be visible in the Business Register.
These are the differences between the NMI and blocking your address:
| NMI | Shielding your address |
|---|---|
| Prevents your address from being used for advertising | Prevents your address from being visible in the Business Register |
| Your address remains visible | Your address is no longer visible |
| Protection against marketing and advertising | For privacy and safety |
Your phone number in the Business Register
Your phone number as listed in the Business Register is not public. Only organisations that have authorisation, such as the Netherlands Tax Administration or civil-law notaries, can view your phone number. They may only access it if it is needed for them to do their legal duties.
Frequently asked questions
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 . 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.
The Business Register Act (Handelsregisterwet) states 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.
