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.
- When the search returns nothing
- Ask for the RCS number, search former names and distinguish a branch from its parent. An access restriction or missing document should be reported as unavailable, not as a confirmed absence of a company.
- What the record cannot establish
- RCS registration does not automatically provide unrestricted beneficial-ownership data. Preserve the dates and scope of documents; officer information does not by itself establish ultimate ownership.
Check current access and document options on the official RCS (Registre de Commerce et des Sociétés) site. Keep the exact entity identifier, source URL and retrieval date with your evidence. A LemReveal record PDF is not a government-certified extract.

Frequently Asked Questions
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).
What is a S.à r.l.?▾
S.à r.l. (Société à responsabilité limitée) is Luxembourg's limited liability company. Minimum capital is €12,000. It's the most popular company form for holding structures and operating companies.
How do I search Luxembourg companies?▾
The RCS portal (lbr.lu) provides free access to company data. The RESA (Recueil Électronique des Sociétés et Associations) publishes official company announcements.
What is a SCSp?▾
SCSp (Société en commandite spéciale) is Luxembourg's special limited partnership, widely used for private equity and venture capital fund structures. It offers tax transparency and governance flexibility.
How do I search for a company in Luxembourg by name?▾
Use the available lookup or the linked official RCS Luxembourg service. Start with the legal name, then compare the exact RCS number and available identity fields. Name matches are candidates; source coverage and partial-name support vary.
Is the Luxembourg company register free to search?▾
Basic company lookup is free on LemReveal. The official Luxembourg register has independent access rules and may require an account or charge for searches, extracts or particular documents. Check the source's current terms.
Can I search Luxembourg companies by registration number?▾
Where the source supports it, use the exact RCS number together with its register or jurisdiction. Preserve prefixes and leading zeros and compare the returned legal name. A number alone does not guarantee coverage or a successful lookup.
How do I check whether a company is registered in Luxembourg?▾
Search the exact RCS number or legal name above, then confirm the entity's identifier and source. An empty result can reflect coverage limits, a source outage, spelling or a different jurisdiction; it does not prove the business is unregistered. A fuzzy candidate is not a confirmed identity.
How can I tell if a Luxembourg company is still active?▾
Read the status and effective date where the RCS Luxembourg supplies them. Active registration does not establish trading or financial health. Monitoring is available only for supported sources and confirmed records; verify the actual watch state.
How do I find a company's RCS number?▾
Identify the legal entity using the available lookup or official RCS Luxembourg route. Record the RCS only where supplied, with its source and jurisdiction. Do not infer missing identifiers from a similar name.
