Frequently asked questions
How do I check if a company is registered in Luxembourg?
Search the company's name or registration number on RCS Luxembourg at https://www.lbr.lu. A matching entry with an "active" or equivalent status confirms the company is currently registered. The check is free and needs no account.
How can I check if a Luxembourg company is still active?
Read the status field on the company's RCS Luxembourg record. "Active"/"registered" means it is currently on the register; "dissolved", "struck off" or "liquidation" means it is not. Also check the most recent filing date — a nominally active entity years behind on filings is a warning sign.
Is a Luxembourg company with a website automatically registered?
No. A website, email domain or invoice letterhead proves nothing. The only authoritative proof is a current entry in RCS Luxembourg with a matching legal name and registration number.
What proves a Luxembourg company is legally registered?
An entry in RCS Luxembourg with an "active" or equivalent status is the definitive proof. The registration number returned by RCS Luxembourg is the authoritative identifier.

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).
