How to protect yourself and your company from scams

On this page, we have compiled information about how you can protect yourself from scams in Trade Register and trademark matters. Read further instructions by clicking on the links under each subject or by opening the pages in the menu.

Take special care of personal identity codes and home addresses

The Trade Register is a register for public use. Anyone is entitled to obtain information about the entries made in the register. This principle of open access also applies to all notifications and enclosures filed with the Trade Register. Therefore, do not declare any personal identity code and home address unless specifically requested. When you send notifications, do not include any documents that contain personal identity codes, home addresses, or sensitive details, such as health details.

Beware of misleading communications

As a client of the Finnish Patent and Registration Office (PRH), you might receive letters, phone calls, invoices and payment reminders that have nothing to do with the PRH. Most of these are in English and come from abroad, but it is possible that someone will contact you from Finland and in Finnish.
