    How do I find the right registered entity in Luxembourg?

    A registry entity search in Luxembourg identifies which specific legal entity you are dealing with when a name is shared across several. RCS Luxembourg distinguishes them by registration number, entity type (S.à r.l. (Société à responsabilité limitée), S.A. (Société anonyme), S.C.A. (Société en commandite par actions)) and registered address.

    Step-by-step

    1. 1

      Search the name and expect several hits

      Groups commonly register holding, trading and dormant entities under near-identical names. The first result is not necessarily the one you are dealing with.

    2. 2

      Disambiguate by registration number

      The registration number is unique. If a counterparty cannot give you theirs, that is itself informative.

    3. 3

      Compare entity type and address

      Where the number is unavailable, entity type (S.à r.l. (Société à responsabilité limitée), S.A. (Société anonyme), S.C.A. (Société en commandite par actions)) and registered address usually separate the candidates.

    4. 4

      Record which entity you chose

      Contracts are with an entity, not a brand. Note the registration number you verified so later checks look at the same record.

    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.

    Frequently asked questions

    Why do several Luxembourg entities share the same name?

    Groups register separate legal entities — holding, operating, dormant — under closely related names. RCS Luxembourg treats each as a distinct entity with its own registration number.

    How do I tell which entity I am contracting with?

    By registration number. Ask the counterparty for it, then confirm that exact number on RCS Luxembourg. Name alone is not sufficient.

    Is entity search on RCS Luxembourg free?

    Check official search, account and fee rules. LemReveal's basic lookup is separate from official document and subscription charges.

    Does the biggest entity in the results matter most?

    No. What matters is the entity named on your contract or invoice. A dormant shell and a trading company in the same group look similar in a name search and carry very different risk.

    Why is Luxembourg a financial hub?

    Luxembourg offers political stability, a multilingual workforce, favorable holding company and fund regimes, extensive double taxation treaty network (80+ countries), and is the EU's largest domicile for investment funds (over €5 trillion AUM).

    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.
