    2. 2

    Luxembourg: choosing and checking the right record

    Choose the correct source
    Use Luxembourg Business Registers for the RCS entity and available filed documents. Keep an RCS check separate from any beneficial-ownership inquiry, which can have different access conditions.
    Confirm the entity
    Match the full RCS identifier, including its section letter, with the legal name and legal form. Similar names or group membership are not sufficient to select the contracting entity.

    Check current access and document options on the official RCS (Registre de Commerce et des Sociétés) site. For search limitations and missing-result guidance, see the Luxembourg registry guide.

    Is the Luxembourg company register free to search?

    Yes. Basic company lookups on the RCS (Registre de Commerce et des Sociétés) 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 Luxembourg business registry?

    The RCS (Registre de Commerce et des Sociétés) is the official public register of companies incorporated in Luxembourg. It is operated by the government and is the primary source cited on this page — https://www.lbr.lu.

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

    Every registered Luxembourg 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 RCS (Registre de Commerce et des Sociétés) record.

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

    No. The registration number is the identifier issued by the RCS (Registre de Commerce et des Sociétés) 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.
