The Register of Commerce and Societies (RCS) (the Commercial and Companies Register) is an official register of all natural and legal persons involved in the economic life of Luxembourg and other persons subject to the Act of 19 December 2002, as amended. The Luxembourg company registration process is required for most legal structures chosen to incorporate in Luxembourg.

The RCS is subordinate to the Minister of Justice. The administration of the RCS is carried out by the Minister of Justice of the Economic Interest Grouping, which includes the State, the Chamber of Commerce and the Chamber of Crafts.

This register exists since 1909. It has been under the jurisdiction of the Minister of Justice since 2003 and is managed on its behalf by the GIE RCSL economic interest group. Since then, the register is completely converted to EDP. The documents deposited with the RCS since 1 January 2006 are systematically digitized and can be viewed on the website. The documents deposited since the founding of the RCS in 1909 are digitized and gradually made available to the public. The RCS will then be fully electronically viewable.
