    How do I look up a company by its registration number in Estonia?

    Use the exact Reg. code with its issuing jurisdiction or register on e-Business Register (Äriregister). Compare the returned legal name and identifier. A valid-looking number does not guarantee a result: coverage, formatting, access and source availability affect the lookup.

    Step-by-step

    1. 1

      Find the Reg. code on the paperwork

      The Reg. code normally appears on invoices, contracts, the website footer or official correspondence. It is the number counterparties are required to quote.

    2. 2

      Search the Reg. code

      Preserve leading zeros, letters, court and jurisdiction information. Follow the source's documented format rather than removing meaningful parts to force a match.

    3. 3

      Confirm the returned entity

      Check the legal name on the returned record matches the name on your paperwork. A mismatch between quoted number and quoted name is a serious warning sign.

    4. 4

      Verify at e-Business Register (Äriregister)

      For anything contractual, confirm the number against the primary source at https://ariregister.rik.ee.

    Estonia: choosing and checking the right record

    Choose the correct source
    Use the e-Business Register and search the exact registry code where possible. Open the entity record before selecting a report or historical entry; the company profile and a filed annual report have different dates and scope.
    Confirm the entity
    Match the registry code, legal name and legal form. Distinguish a management-board member from a shareholder and read the available representation rules. e-Residency is an identity programme, not the company's registry status.

    Frequently asked questions

    What is a Reg. code in Estonia?

    It is the identifier e-Business Register (Äriregister) assigns to a registered entity. It stays with the entity even if the trading name changes, which makes it the reliable way to track a company over time.

    Is a Reg. code lookup free?

    LemReveal's basic lookup is free where supported. Check e-Business Register (Äriregister)'s official access rules for the record or document required.

    What if the Reg. code returns no result?

    Check the format, issuing jurisdiction, coverage and source availability. Preserve meaningful prefixes and leading zeros. An unavailable source is not a confirmed absence; ask the counterparty to clarify the identifier.

    Should I use the Reg. code or the company name?

    The Reg. code. Names are duplicated across entities within a group; the number is unique to one entity.

    What is an OÜ?

    An OÜ (Osaühing) is an Estonian private limited company. Since 1 February 2023 the minimum share capital is €0.01 per shareholder, with contribution at formation. The former €2,500 minimum no longer applies. Online formation requires the applicable identification and registration steps; it is not a guaranteed 18-minute process.
