    How do I search the business registry in Luxembourg?

    The Luxembourg business registry is operated by RCS Luxembourg. It covers S.à r.l. (Société à responsabilité limitée). Search by business name to find the registered entity behind a trading name — free, no signup.

    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.
