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 the subpages in the main menu.
Take special care of personal identity codes and home addresses
The Finnish Trade Register is a register for public use. Anyone is entitled to obtain information about the entries made in the Finnish Trade Register, as well as the filed notifications and their enclosures. Therefore, do not give any personal identity codes and home addresses unless specifically requested. Do not attach any documents that contain personal identity codes, home addresses, or sensitive information, 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 misleading communications are in English and come from abroad, but it is possible that someone will contact you from Finland and in Finnish.
Beware of scam websites
Follow closely which website you are at. Scam websites may include content from the PRH websites and the layout can be similar to them. Check the website address in your browser. The website you are at now is at https://www.prh.fi/fi/index.html. The other PRH website, ytj.fi, is at https://ytj.fi/.
Be alert when identifying yourself and always check the website address. The correct address for Suomi.fi e-Identification is https://tunnistautuminen.suomi.fi.

Private trader: choose only online notifications
Private traders can still choose to submit their notifications to the Finnish Trade Register using paper forms. As of 2026, other company types must file their notifications to the Finnish Trade Register online.
When you file your notification online at ytj.fi as a private trader, choose that your company can only file notifications online. This is how you make sure that only authorised persons will be able to file notifications with the Finnish Trade Register for your company in the future.
