    How do I find a company's registration number in Estonia?

    Search the company's name on e-Business Register (Äriregister) at https://ariregister.rik.ee. The result page shows its registration number — the same identifier that appears on invoices, contracts, and government filings.

    Step-by-step

    1. 1

      Open e-Business Register (Äriregister)

      Navigate to https://ariregister.rik.ee.

    2. 2

      Search by company name

      Type the exact trading or legal name. Partial matches usually work; add the city if the name is common.

    3. 3

      Copy the registration number

      The registration number is displayed at the top of the entity profile. It is the authoritative ID for cross-referencing.

    4. 4

      Confirm it's the right entity

      Check the registered address and incorporation date to be sure you have the correct legal entity, especially for groups with similarly named subsidiaries.

    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

    Where is a Estonia company's registration number published?

    Look for the identifier on the entity's record or available extract in e-Business Register (Äriregister) (https://ariregister.rik.ee). Compare it with the counterparty's documentation; publication requirements and identifier labels vary by jurisdiction.

    Is looking up a Estonia registration number free?

    LemReveal's basic lookup is free. Check e-Business Register (Äriregister)'s current access rules: an official portal can require an account, charge for searches or restrict particular documents.

    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.

    Where do I find a Estonia company's registration number?

    Every registered Estonia entity has a unique registration number issued at incorporation. It appears on invoices, contracts, the company's website footer (often in a "legal" section), and prominently on its e-Business Register (Äriregister) record.

    Is a Estonia registration number the same as a VAT number?

    No. The registration number is the identifier issued by the e-Business Register (Äriregister) when the company was formed. The VAT number is a separate tax identifier issued (only if the company is VAT-registered) by the national tax authority. Many small companies have a registration number but no VAT number.
