Estonia Company Registry: 2026 KYB Guide
Estonia’s company registry – the E-Business Register – is one of the most impressive the Kyckr Team has come across.
Transparent, detailed, and built for modern KYB systems, it’s easy to use and useful for UBO verification. We accessed the registry on March 11, 2026.
The following is a guide for compliance professionals trying to navigate the E-Business Register.
Estonia's E-Residency Programme
Estonia launched e-residency in 2014. It lets any non-Estonian apply for a digital identity and use it to register and run an Estonian company without ever moving there.
The numbers are large. More than 128,000 people from 185 countries have joined, founding over 36,000 companies. e-Justice E-resident companies now account for roughly one in five new Estonian businesses each year.
This matters for KYB. A company registered in Tallinn may have no connection to Estonia whatsoever. Its founder might live in Kyiv, Lagos, or Buenos Aires. The E-Business Register will show you the entity clearly, but what it cannot tell you is whether the person behind it is who they say they are, or whether they operate elsewhere under a different structure.
What Data Is Available?
Basic: Name, registry code, legal form, status, registration date, and financial year.

Estonian Legal Entities
Private Limited Company (OÜ): Must file an annual report, even if the company had zero activity. SMEs must also disclose a management report and detailed notes on ownership. All companies must declare and maintain an updated list of Ultimate Beneficial Owners (UBOs).
Public Limited Company (AS): Required to file an annual report, disclose the activities of their supervisory board and provide transparency regarding major shareholders. Like all entities, they are obligated to report their beneficial ownership data to the Business Register within 30 days of any change.
Sole Proprietor (FIE): Must submit a simplified annual report to the registry to maintain their legal standing. While they do not have separate "shareholders," they must disclose their personal identity and primary business address as part of their public profile.
Non-Profit Association (MTÜ): Required to file an annual report, disclose any donations or gifts received, and those on the tax-incentivised list must file additional declarations regarding the use of their assets. Management board members and beneficial controllers must be publicly registered.
General and Limited Partnerships (TÜ & UÜ): Must file an annual report, disclose the identity of all general partners with unlimited liability and the specific financial contributions of any limited partners. Beneficial ownership data must also be reported.
Branch of a Foreign Company (Filiaal): Must file the audited and approved annual report of its foreign parent company, which must be translated into Estonian for public inspection. While the branch has no separate shareholders, the parent company's legal status and authorised representatives must be fully disclosed.
How to Conduct an Estonian Company Search
The Estonian company registry has an easy-to-use online portal with a simple UX design.

You can search by name, registry code, or VAT number. When you type in a name, entities automatically appear in a dropdown menu.
3. View Results.
A basic search result shows entities by name, registry code, status and address.
Sort: You can sort the results by name, registry code, status and address, either ascending or descending.

Estonia’s Beneficial Ownership Register
UBO Data Remains Public (For Now)
Beneficial ownership information is available to the public for free on the E-Business Register.
This was true when the Kyckr Team accessed the E-Business Register on March 11, 2026.
However, Estonia is transposing the 6AMLD into national legislation. Following successful implementation, UBO access will be granted to those who can prove a legitimate interest.
What UBO Data Is Available?
The E-Business Register offers the following data point
Name.
Shareholding.
Ownership graph
Address.
Personal ID.
History.
Criminals Cross Borders
The E-Business Register is one of the most transparent in Europe, but bad actors don’t play by the rules. They use nominees to conceal the real owner, circular ownership structures and shell companies – sprawling networks spanning continents. Estonia shows you what the company says about themselves, but they can’t show you what they say on all the other registries.
Kyckr can. We provide a single live access point to the world’s official company registries. Which means if you search for a legal entity on Kyckr, you are searching 300+ official company registries in real time. Not static data. Not one registry or two. But all of them.
