Non-disclosure of personal data

Everyone has the right to block the sharing of their data for purposes such as direct marketing, inclusion in public registers, genealogical research, or for updating customer or similar databases. Furthermore, individuals can restrict the release of their contact information for use in contact or address services or similar data services. The non-disclosures are personal in nature and valid until further notice, which means that they do not need to be renewed, for example, when you are moving house.


The following information can be recorded in the Population Information System for an individual:

  • non-disclosure for direct marketing purposes
  • non-disclosure of contact information
  • non-disclosure of customer register update
  • non-disclosure for genealogical research purposes
  • non-disclosure for public registers


You can prohibit the disclosure of data on the Suomi.fi Web Service's Personal Data page or by notifying the Digital and Population Data Services Agency by phone, form or via a free-form letter.

If you need more stronger security measures to protect your address, you can apply for a non-disclosure for personal safety reasons (turvakielto in Finnish).
