Protecting your data with the non-mailing indicator

For direct marketing campaigns conducted by mail, businesses and organisations can request address databases from the Chamber of Commerce. If you activate the non-mailing indicator (NMI) for your registration in the Commercial Register, the amount of paper mail from such campaigns you receive will drop.

How to activate the NMI

Will you be registering with the Chamber of Commerce?

When registering in the Commercial Register, you can indicate that you do not want your details made available for direct marketing campaigns for the duration of your registration.

Are you already registered at the Chamber of Commerce?

There is a form for easily switching the non-mailing indicator on or off (only in Dutch).

How quickly will mailings end?

As soon as we have activated the NMI (within a few working days) and any address database users have processed this, the number of mailings should drop. Address database users are required to process the NMI in their databases.

I am still receiving mail, why?

The NMI is not a guarantee that your address will no longer be used for direct marketing campaigns. If businesses continue to send you mail, this could have one of these reasons:

  • The address details come from another source than the Chamber of Commerce, such as commercial suppliers.
  • Businesses create their own database by collecting information publicly available on the internet, also known as scraping. This could concern your listing in the telephone book or Yellow Pages, a municipal business guide or the contact details on your website.
  • Your details may still be found in old databases in use.

Your details remain available on request

Even if you activate the NMI, your registration in the Commercial Register will remain visible. The Commercial Register is public and the information must be accessible to everyone.

The Commercial Register lists all businesses, legal entities and other organisations that participate in economic transactions in the Netherlands. The Commercial Register shows you who you are dealing with, who is authorised to sign on behalf of the company and whether perhaps liquidation has ensued. This provides certainty when doing business. The public nature means that everyone can consult your details.
