How to check companies in Luxembourg

The business registration system in Luxembourg

Luxembourg has a transparent and highly regulated business system that allows anyone to verify the information corresponding to a company registered in the country. This is especially relevant for those who wish to establish commercial relationships, invest or guarantee the legitimacy of a company with which they plan to interact.

The official database where all the information about companies active in Luxembourg is registered and maintained is the Luxembourg Trade and Companies Register (RCS), which is managed by the Luxembourg Business Registers (LBR). The information in this register is published in the Recueil électronique des sociétés et associations (RESA), the RCS's publication platform that acts as an official gazette.

All legal entities operating in the country are registered in the RCS, from limited liability companies (SARL) to non-profit associations and cooperatives. This register not only makes it possible to verify the existence of a company but also to access a large amount of information about it, such as its legal form, date of incorporation, share capital, statutes and the names of the legal representatives. Furthermore, any significant change in a company, such as modifications in its shareholding structure, changes in management or even its dissolution must be reported and updated in the RCS.

FAQ

Is it free to check a company’s registration in Luxembourg?

Yes, basic searches in Luxembourg’s Registre de Commerce et des Sociétés (RCS) are free, and you can access general company details like registration number, legal form, and even download certain documents, such as statutes, at no cost. However, fees may apply in specific cases: if you request certified copies of documents, access older records that require digitization, or you want to download detailed reports.

What is the difference between the RCS and the RESA?

The RCS (Registre de Commerce et des Sociétés) is the official business register. It contains key information about each entity, such as its legal form, representatives, and status. The RESA (Recueil électronique des sociétés et associations) serves as the official publication platform for mandatory legal announcements: changes to company statutes, mergers, appointments of directors, or liquidation notices. In short, the RCS is a repository of company data, while the RESA is a communication tool for publishing legal records.

Can I access financial information about a company through the RCS or RESA?

Yes, in some cases. Companies that are required to file financial statements, such as large entities or public companies, must submit these documents to the RCS. However, not all companies, especially smaller ones, are required to file financial information.

Are all types of companies in Luxembourg required to register with the RCS?

Yes, all companies operating in Luxembourg, regardless of size or business type, must register with the RCS. This applies to commercial companies (SARL, SA, SC, etc.), non-profit organizations, partnerships, and even certain professionals, such as notaries or lawyers, operating under specific legal forms.

How do I verify if a company is active or has been dissolved?

To verify a company’s status (active, dissolved, or in liquidation), you may need to look beyond the initial search results provided by the RCS. After finding the company in the search list, you can access the detailed company profile or download documents such as recent publications in the RESA. These documents, such as dissolution notices or liquidation updates, will indicate the current status.
