You can restrict the disclosure of your personal data to third parties in the Digital and Population Data Services Agency's online service

The Digital and Population Data Services Agency reminds you that you can add or remove data disclosure prohibitions in the Suomi.fi Web Service.

In practice, this means that you can prohibit the disclosure of your personal data, such as your address, to direct marketing or customer registers, for example. This will take a few minutes.

You can check your personal data kept in the Population Information System on the personal data page of the Suomi.fi Web Service.
In addition to managing data disclosure prohibitions, you can check the validity of your current personal data in the service and activate Suomi.fi Messages to minimise paper post. You can identify yourself on the website with your online banking ID, mobile certificate or citizen certificate on your ID card.
