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

    Use the exact CRO with its issuing jurisdiction or register on CRO Ireland. 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 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

      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 CRO Ireland

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

    Ireland: choosing and checking the right record

    Choose the correct source
    Use CRO's official company search and distinguish a company registration from a business-name registration. Review the filing record and any available officer document relevant to your question.
    Confirm the entity
    Compare the CRO number and legal name. A business name is a trading label and may be registered to an individual or another entity; identify that underlying contracting party.

    Check current access and document options on the official Companies Registration Office (CRO) site. For search limitations and missing-result guidance, see the Ireland registry guide.

    Frequently asked questions

    What is a CRO in Ireland?

    It is the identifier CRO Ireland 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 CRO lookup free?

    LemReveal's basic lookup is free where supported. Check CRO Ireland's official access rules for the record or document required.

    What if the CRO 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 CRO or the company name?

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

    How do I search the Irish CRO?

    Visit the CRO's CORE search system (core.cro.ie) and search by company name or number. Basic company details are free. Document images (annual returns, financial statements) can be purchased for a small fee.
