B2B leads in Finland. Start from the register.
International contact databases are built largely from websites and profiles, and many small and mid-size companies in Finland barely show up in them. The official register has every company. Here is how to go from the register to a list you can work.
What Atlas holds for Finland
Source: the Atlas database, updated automatically.
1. The official sources
- PRH trade register and YTJ: business ID (Y-tunnus), name, company form, registration date, address, TOL 2008 industry code and status. Open data with a free API.
- Tax administration: public tax data for companies is published yearly.
- Municipal purchase invoices: many municipalities publish them as open data, which shows who already sells to the public sector.
2. Define the segment
Use three coordinates the register can answer: the industry code, the region and the size. Add a reason to get in touch now, such as a newly registered company, a new director or a won public tender.
3. Remove closed companies
The PRH company endpoint also returns closed companies. On 22 July 2026 it returned 821 699 companies, of which 461 107 were registered. Filter on status. Read more in our register audit.
4. Find the contact
The company's own website gives the contact page, the management and open jobs. Check that the website really belongs to the company, with the registration number or a distinguishing name on the page. Parked domains and pages of another company with a similar name are a common source of wrong data.
5. The rules for outreach
In Finland, email marketing to a person's work address is allowed when it relates to their work role and opting out is easy. The GDPR applies to named contacts.
This is a general overview, not legal advice.
How Atlas helps
Atlas searches companies by industry, region and registration date, and looks for the website, phone, email and decision-maker in public sources. The source is shown next to every piece of data, and if nothing is found the field stays empty. Coverage varies a lot by country, see the measured coverage page. Price: 600 euros for two months plus VAT, no credits.
