New feature in our open data service: interface to add Trade Register notifications to your application

We have further revamped the PRH open data service, which allows application developers to access company data.

You can now use the service’s interface to retrieve details of notifications registered at the Finnish Trade Register. You can access the date of registration, the subject matter of register entries, and basic details about companies.

The interface provides details of notifications registered since 7 November 2014. The service does not provide information about notifications filed by private traders.

You can download the information as compressed files.

Notifications can be filed with the Finnish Trade Register by companies whose form requires them to be in the Trade Register. The forms of companies in the Trade Register are listed here.

Use the new interfaces now

The service provides interfaces to basic details in the Finnish Business Information System at ytj.fi and to notifications filed with the Finnish Trade Register. We have made technical changes to the interfaces.

Start using the new interfaces now to avoid interruptions to the service. You will find the new interfaces and our instructions for use at https://avoindata.prh.fi/en.Open link in a new tab

Our aim is to ensure that the old interfaces are available until the beginning of 2025.
