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

    Enter the CRO to look up a Ireland company directly on CRO Ireland. Unlike a name search, an CRO 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 CRO on the paperwork

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

    2. 2

      Search the CRO

      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 CRO Ireland

      For anything contractual, confirm the number against the primary source at https://www.cro.ie.

    What if the CRO returns no result?

    Re-enter it without spaces or punctuation first. If it still returns nothing, the number may be mistyped, belong to a different country's register, or not exist — ask the counterparty to confirm it in writing.
