Estonian Business Register: What It Shows and How to Get a List
Updated 2026-08-14 · 7 min read
The business register is Estonia's official company registry, maintained by the registration department of Tartu County Court. It records every active company's name, registry code, legal form, address, activity field, and board members.
Looking up a single company in the register is easy. It gets harder when you need an entire target audience — say, every construction company in Harju County along with their email addresses, in one file. This guide covers what the business register gives you, what it doesn't, and how to build a list in practice.
What data is public in the business register
A large share of business register data is public information that can be used commercially. Kontabase's dataset is built directly from these fields and supplements them with public contact data.
- Company name and registry code
- Legal form: private limited company, public limited company, non-profit, foundation, sole proprietor, general or limited partnership
- Address, county, and city
- EMTAK activity field and description of core activity
- Board members and rights of representation
- Annual report figures: revenue and employee count, if disclosed
- Status: active, in liquidation, or deleted
How to search for a company in the business register
The official information system lets you search by company name, registry code, or person. This works well for checking a single company: is the partner active, who's on the board, and what do the latest reports show.
The registry interface isn't built for bulk search — filtering hundreds or thousands of companies at once by activity, county, size, and contact availability. Nor does it produce a ready Excel list you can take straight into sales or email marketing.
Business register data as a list: what the registry doesn't give you
The registry doesn't compile companies' public email addresses or phone numbers in a form ready for a campaign. Nor can you get a filtered export that combines activity, county, size range, and contact data all at once.
Kontabase's builder handles exactly this step: you choose filters, instantly see the number of companies and how many have an email and phone, and download the file right after payment. Before buying, you get a free 25-row sample.
- Filter by EMTAK sector, county, legal form, employee count, and revenue

- Get an XLSX or CSV file immediately, with no sales call
What you're allowed to do with business register data
A business offer sent to a company's public general contact is allowed in Estonia if it relates to the company's activity, the sender is identifiable, and every email includes an opt-out.
We do not sell or collect private individuals' personal phone numbers or personal email addresses.
Frequently Asked Questions
- Is using business register data for sales allowed?
- Yes. Public business register company data and a company's public general contact can be used for business outreach as long as the email includes a clear opt-out and the sender is identifiable.
- Can I get an Excel list of all companies from the business register?
- The registry search is built for single lookups. You can get a filtered list with emails and phone numbers from Kontabase's builder in a couple of minutes.
- How fresh is Kontabase data compared to the registry?
- The dataset is refreshed regularly based on registry data, and every record is linked to a registry code, so old records get replaced correctly.
