    How do I search the business registry in Luxembourg?

    Use RCS Luxembourg as a starting source for Luxembourg, then check its scope for the business form you need. Types can include S.à r.l. (Société à responsabilité limitée). A trading name may need a separate source or document; it does not automatically identify a legal entity. Official access requirements vary.

    Step-by-step

    1. 1

      Search the trading name you were given

      Start with the name on the invoice, website or contract. It is often a trading name rather than the registered legal name.

    2. 2

      Identify the legal entity behind it

      RCS Luxembourg records the legal entity. Matching a trading name to its registered entity is the whole point of a registry search — the two are frequently different.

    3. 3

      Check the entity type

      Luxembourg recognises S.à r.l. (Société à responsabilité limitée). Entity type determines liability and who is legally responsible, so it matters before you contract.

    4. 4

      Note what the registry does not cover

      Sole traders and unregistered activity may not appear at all. An absent record is not automatically proof of fraud — it can simply mean the business is not required to register.

    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

    What does the Luxembourg business registry cover?

    RCS Luxembourg records S.à r.l. (Société à responsabilité limitée). Businesses that are not legally required to register — commonly small sole traders — may not appear.

    Can I search the Luxembourg business registry by trading name?

    Some sources index trading names; others require the legal name or a separate business-name search. Ask for the contracting entity's legal name and identifier when the relationship is unclear.

    Is a business registry search free in Luxembourg?

    LemReveal's basic lookup is free where supported. Official searches, records and documents have their own access conditions; check RCS Luxembourg's current terms.

    What if a Luxembourg business has no registry entry?

    It may not be required to register, or it may be trading under a different legal name. Ask for the registration number directly before assuming either.

    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).
