What is RCS Luxembourg?
The RCS is Luxembourg's official trade and companies register, operated by LBR (Luxembourg Business Registers). Search at lbr.lu for any Luxembourg entity's RCS number, form, address, and filings.
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.
The RCS holds legal records for every entity domiciled in Luxembourg — SA, SARL, SCS, SCA, funds, and holding structures. Given Luxembourg's role as a financial hub, RCS data is essential for M&A, fund research, and beneficial-ownership due diligence.
