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

    Enter the Reg. code to look up a Estonia company directly on e-Business Register (Äriregister). Unlike a name search, an Reg. code returns exactly one entity, which is why it is the identifier to use for KYC, invoicing and contract checks.

    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

      Enter the number exactly as printed. Punctuation and spacing vary between documents — strip them if the search returns nothing.

    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.
