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
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
Disambiguate by registration number
The registration number is unique. If a counterparty cannot give you theirs, that is itself informative.
- 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
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.
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?
Yes — search and the public entity record are free and need no account.
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).
