Estonia publishes things no other register in this series publishes.
Directors, shareholders, share capital, the articles of association, full annual reports, declared turnover, the number of employees, and whether the company owes tax. All free, no account, from anywhere in the world.
Then, in 2025, it closed the one thing everybody assumed would stay open: the beneficial owner register.
Both halves of that story matter, and most guides still tell only the first. Here is the current state of the register.
Where it is and what it costs
The register is the e-Äriregister, the e-Business Register, at ariregister.rik.ee. It is maintained by the Registration Department of Tartu County Court and operated by RIK, the Centre of Registers and Information Systems.
Since 1 October 2022, the data is free of charge, including annual reports. Before that date, documents cost one or two euros each.
There is no login for public queries and no registration. A compliance team anywhere in the world can search Estonian companies, read directors and shareholders, and download the articles of association without creating an account.
The one charge that survives: two euros to view a document from the public file of a non-profit organisation.

The registry code, and why you should search by it
Every Estonian entity has a registrikood, a permanent eight digit registration code.
It does not change. Not when the company changes name, not when it restructures, not when the directors are replaced. Every Estonian government system, every tax filing, every VAT invoice and every bank account references it.
| Search by | Reliability |
|---|---|
| Registry code | Exact, permanent, unambiguous |
| Company name | Works, but breaks on name changes and near-matches |
| VAT number | Works, and links the tax identity to the entity |
If a counterparty gives you a name and not a registrikood, ask for the code. It costs them nothing and removes every ambiguity from your search.
The three ways to query
Quick search takes a name or a registry code and returns entities with their status and address.
Detailed search opens extended parameters, including searching by a private person. Like the Companies House officer search, this turns one name into a map of everything they are attached to.
Activity search uses the EMTAK classifier, Estonia's activity coding system. Useful when you are mapping a sector rather than checking one company.
What a company record shows
| Field | Free |
|---|---|
| Name, registry code, status | ✅ |
| Registered address | ✅ |
| Area of activity (EMTAK) | ✅ |
| Directors and board members | ✅ |
| Shareholders | ✅ |
| Share capital | ✅ |
| Articles of association | ✅ downloadable |
| Annual reports | ✅ since 1 October 2022 |
| Declared turnover | ✅ |
| Number of employees | ✅ |
| Tax arrears | ✅ |
| Missing tax declarations | ✅ |
| Business prohibitions | ✅ |
| Licences for economic or excise activities | ✅ |
| Commercial pledges | ✅ |
| Beneficial owners | ⚠️ restricted, see below |
Three of those lines have no equivalent anywhere else in this series.
Declared turnover and headcount
Estonia publishes what a company told the tax authority it turned over, and how many people it employs.
No other register in this series does. In the UK you can infer scale from filed accounts, with a delay of up to nine months. In Hong Kong and Singapore you cannot see it at all. In Delaware there is nothing to see.
For screening a supplier or a prospective partner, this is the fastest signal available anywhere: a company claiming a fifty person operation with two declared employees is a conversation you can have before signing anything.
Tax arrears and missing declarations
The register shows whether a company owes tax and whether it has failed to file declarations.
This is a live solvency and diligence signal, published by the state, for free, about any Estonian company. It is the single most useful field in the whole register and it is barely mentioned in the guides that currently rank.
Annual reports, and why the format matters
Filing an annual report is mandatory for every Estonian accounting entity, once per financial year, for as long as the entity exists. The report contains the financial statements and an activity report.
Since October 2022 they are free to access. Larger private companies and listed companies file in iXBRL, a machine-readable format.
That combination, mandatory filing plus free access plus machine readability, makes Estonia one of the very few EU jurisdictions where you can run genuine financial analysis on private companies straight from public registry data.
The beneficial owner register closed, and reopened differently
This is the part almost every page currently ranking gets wrong.
What happened. On 22 November 2022 the Court of Justice of the European Union ruled that general public access to beneficial ownership information constitutes a serious interference with the fundamental rights to private life and data protection.
Member states were no longer required to provide public access. They were required instead to provide it, at minimum, to those who can demonstrate a legitimate interest.
What Estonia did. It restricted public access to beneficial owner data in 2025.
Where it stands. The register reopened in January 2026 under a tiered access model. Access is available to competent authorities, to anti-money-laundering obliged entities such as credit institutions and financial service providers acting in the course of customer due diligence, and to other parties who can demonstrate a legitimate interest.
General public access is no longer available.
| Who you are | Access to Estonian UBO data |
|---|---|
| Competent authority | ✅ |
| AML-obliged entity performing customer due diligence | ✅ |
| Party able to demonstrate a legitimate interest | ✅ on demonstration |
| A member of the public checking a supplier | ❌ |
Two practical consequences.
If you are a regulated business running customer due diligence, nothing much changed for you. If you are a founder or a journalist checking who is behind an Estonian company, the route that existed until 2025 is closed.
And the wider EU picture is still moving. Estonia's obligations under the sixth Anti-Money Laundering Directive and the Anti-Money Laundering Regulation continue to develop through 2026. Check current eligibility before assuming either access or refusal.
Open data, and the contrast with Delaware
Estonia publishes downloadable open data sets from the register, including current beneficial owner lists in the open data context and general annual report statistics for the three previous financial years.
This is the opposite posture from Delaware, whose search page states that it "strictly prohibits mining data" and warns that automated tools may result in suspension of access.
Same activity, bulk analysis of a national company register. One jurisdiction publishes the files for you. The other threatens to cut you off.
If you need Estonian data at scale, use the open data downloads rather than hammering the search interface. It is faster, it is intended for that, and it is free.
Digital identity, and where the wall is
Public queries need nothing. Doing anything needs an Estonian digital identity.
Applications and reports can only be signed with an Estonian ID card, Smart-ID or mobile ID. That covers establishing a company, changing registered data, submitting petitions and filing annual reports.
This is the practical function of e-Residency: it gives a non-resident the digital identity needed to operate on the Estonian side of the wall. It does not affect your ability to search.
⚠️ e-Residency eligibility is assessed by nationality and background, and has been suspended or restricted for certain nationalities. Check before building a plan around it.
How Estonia compares
| Estonia | United Kingdom | Singapore | Hong Kong | Delaware | |
|---|---|---|---|---|---|
| Directors | Free | Free | S$5.50 | HK$22 | ❌ |
| Shareholders | Free | Free, over 25% | S$5.50 | ❌ | ❌ |
| Annual accounts | Free, iXBRL | Free PDFs | ❌ mostly | ❌ | ❌ |
| Declared turnover | ✅ | ❌ | ❌ | ❌ | ❌ |
| Employee count | ✅ | ❌ | ❌ | ❌ | ❌ |
| Tax arrears | ✅ | ❌ | ❌ | ❌ | ❌ |
| Beneficial owners | ⚠️ restricted | ✅ free | S$5.50 | ❌ | ❌ |
| Bulk data | Published | API | Limited | Limited | ❌ prohibited |
On operating data, Estonia is the most transparent register in this series by a wide margin. On beneficial ownership specifically, the UK is now more open than Estonia, which is a reversal of the position most people still assume.
When the company does not come up
You are searching a name, not a code. Estonian names carry the entity suffix, usually OÜ for a private limited company. Search the registrikood instead.
Diacritics. Estonian uses ä, ö, ü and õ. A name typed without them may not match.
It is a branch. A foreign company operating in Estonia registers a branch, held separately.
It is a sole proprietor. Registered, but under the person rather than as a company.

Frequently asked questions
Is the Estonian business register free?
Yes. Since 1 October 2022 the data is free of charge, including annual reports. Previously documents cost one or two euros each. The only remaining charge is two euros to view a document from the public file of a non-profit organisation.
Can you see who owns an Estonian company?
You can see shareholders free of charge. Beneficial owner data is different: public access was restricted in 2025 following the Court of Justice of the European Union judgment of 22 November 2022, and since January 2026 access is tiered, limited to competent authorities, AML-obliged entities performing customer due diligence, and parties who can demonstrate a legitimate interest.
What is a registrikood?
The permanent eight digit registration code every Estonian entity holds. It does not change through name changes, restructuring or changes of director, and it is used across every Estonian government system, tax filing, VAT invoice and bank account.
Can you read an Estonian company's accounts?
Yes, free of charge. Filing an annual report is mandatory for every Estonian accounting entity once per financial year. Larger private companies and listed companies file in iXBRL, which is machine-readable.
Does the register show tax debt?
Yes. It shows tax arrears and missing declarations, which no other register in this series publishes.
Can you see how much an Estonian company turns over?
Yes. The register shows declared trading data including turnover and the number of employees, which is unique among the registers covered in this series.
Do you need an account to search?
No. Public queries need no login and no registration, from anywhere in the world. An Estonian ID card, Smart-ID or mobile ID is only needed to sign and submit things, such as establishing a company or filing a report.
Can you download Estonian register data in bulk?
Yes. Estonia publishes downloadable open data sets, which is the opposite of Delaware's explicit prohibition on data mining. If you need volume, use the open data downloads rather than the search interface.
How do I search by person rather than by company?
Use the detailed search, which allows querying by a private person. It works like the Companies House officer search and returns the entities that person is attached to.
Why can I not find an Estonian company by name?
Try the registry code. Also check the entity suffix, usually OÜ, and the Estonian diacritics ä, ö, ü and õ, which a name typed without them will not match.

Search scope, free access, tax arrears and declared trading data reflect the e-Business Register's published services as of August 2026. The change to beneficial owner access follows the Court of Justice of the European Union judgment of 22 November 2022 and Estonia's subsequent implementation; access rules under the EU anti-money laundering package continue to evolve, so verify current eligibility before relying on it. Annual reports have been free of charge since 1 October 2022.
