The Luxembourg national identification number of one or more registered natural persons is missing

Explanation

One or more natural persons are registered in your entity’s file, but their Luxembourg national identification number is missing. However, the Luxembourg national identification number is mandatory for any natural person registered. You must therefore complete the information relating to the persons concerned by adding their Luxembourg national identification number in order to bring the file into compliance.

In this case, you must also attach an identity document and, where necessary, proof of address. These documents are used to create the Luxembourg national identification number by the manager of the RCS when processing the application.
