Important update for individuals registered with the RCS: Luxembourg National Identification Numbers

Important update for individuals registered with the RCS: Luxembourg National Identification Numbers
Published Date
Mar 24 2025
The Luxembourg Business Registers (LBR) recently published a notice in relation to the Luxembourg national identification numbers (LNIN) of individuals that need to be registered with the Luxembourg trade and companies register (RCS).

The formality of filing with the RCS to update LNIN will remain free of charge until May 31, 2025. From June 1, 2025, this service will be subject to a fee. If the LNINs are not updated, the LBR reserves the right to restrict access to the filing formalities for the relevant entities registered with the RCS. The RCS indicates that this restriction will be enforced from October 1, 2025.

The LBR also reminded that there is no specific legal deadline for correcting registered Luxembourg addresses to ensure they comply with the Registre national des localités et des rues. This update can be carried out simultaneously with any mandatory filings with the RCS, such as during the registration of the renewal of directors' or managers' mandates.

For further information on the LNIN requirements, please refer to our previous e-Alert.
