Company Search in Estonian Registry Data
Updated 2026-08-14 · 6 min read
Company search usually means one of two very different things: looking up a specific company, or finding every company that matches certain criteria. The first only needs a registry lookup; the second needs a filterable dataset.
In this guide we look at how to run a targeted company search in Estonia so the result is a sales-ready list right away, not rows copied one by one.
Which search criteria actually work in Estonia
Some fields in Estonian registry data are consistently filled in, others are patchy. It's worth building your search around the reliable fields.
- EMTAK activity code — the most reliable way to search by sector
- Legal form — OÜ, AS, MTÜ, sole proprietor, general partnership
- County and city — for regional campaigns
- Employee count, including companies with 0 employees as a separate group
- Revenue range — keep in mind some companies have no data
- Contact availability — records with only email or only a phone number
Single-company search vs. list search
If you need data on one company, the public business register is entirely sufficient and free. If you need hundreds or thousands of companies at once, manual searching quickly becomes more expensive than a ready-made dataset.
Kontabase's builder is designed for the second case: set your filters, instantly see how many companies match, and get exactly that range as a file.
How to narrow a search without losing your audience
Start with a broad activity field and narrow one filter at a time, watching how the count changes. If the number drops too fast, you've likely added a filter where the data is partially missing.
For revenue and employee count, it's worth including records where the figure is missing too — many active small companies fall into that group.
