    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.

    Is the Ireland company register free to search?

    Yes. Basic company lookups on the Companies Registration Office (CRO) are free — you can search by company name or registration number, view legal status, registered address and (usually) directors at no cost. Some jurisdictions charge a small fee only for downloading full filed documents.

    What is the official Ireland business registry?

    The Companies Registration Office (CRO) is the official public register of companies incorporated in Ireland. It is operated by the government and is the primary source cited on this page — https://www.cro.ie.

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

    Every registered Ireland 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 Companies Registration Office (CRO) record.

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

    No. The registration number is the identifier issued by the Companies Registration Office (CRO) 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.
