From 1 June 2025, the Luxembourg Business Registers will charge €10.95 per filing for national identification number updates in the trade and companies register (RCS). Non-compliance will lead to restrictions as from 1 October 2025.

The Luxembourg Business Registers (LBR), the administrative authority responsible for managing the Luxembourg Trade and Companies Register (RCS), has confirmed to Paperjam that the 13-digit national identification number (“matricule”) updates in the RCS will incur a €10.95 filing fee, starting 1 June 2025. Entities will face restrictions if updates are not completed by 1 October 2025. According to a representative of the LBR, this measure aligns with the pricing policy for similar services in the business register, although the service remains free of charge until end of May.

The update process aims to ensure the accurate identification of natural persons in the RCS and “improve transparency and accountability,” the representative added.

Who must comply

All individuals registered or to be registered with an entity in the RCS, including partners, authorised representatives and auditors, are required to provide or request the creation of a Luxembourg national identification number, the LBR representative clarified.

Although the requirement “applies exclusively to natural persons,” legal entities must ensure that the individuals associated with them, such as directors, managers and authorised representatives, comply with the obligation.

Fee structure and payment rules

The fee is not charged per individual but per filing submitted for updating or creating an identification number. However, it should be noted that whilst multiple updates or creations included within a single filing will incur a single fee, each separate filing will be charged individually.

“It is possible to update or request the creation of a Luxembourg national identification number for multiple natural persons listed with a registered entity simultaneously, within a single submission,” said the LBR.

Notification process

Since “the Luxembourg national identification number is not publicly accessible in the RCS,” the LBR will, or has already, contacted the individual concerned or an authorised representative via regular post. The representative stated that "this postal notification constitutes the official means of informing the person for whom the number has been requested.”

Update process

For individuals already assigned a Luxembourg national identification number or matricule, no supporting documents are required beyond the number itself.

However, if a new number must be created, applicants need to submit evidence of identity and residence, including:

- Full name (as per passport or national identity card)

- All first names

- Date, place and country of birth

- Gender

- Nationalities

- Address of private residence, supported by valid evidence issued within the last six months (for example, utility bill or a certificate of residence)

Confirmation and processing time

Upon successful processing, applicants will receive a confirmation receipt of the update. If the applicant has authorisation, the Luxembourg national identification number will appear directly on the filing receipt. Otherwise, the newly created identification number will be communicated by post to the individual concerned.

The LBR added that “the standard verification period applied by the RCS administrator is three days.”

Non-compliance

Failure to update an identification number by 1 October 2025 could lead to restrictions on filing services for the relevant entities. The LBR, citing the Grand-Ducal Regulation of 17 February 2025, stated that it reserved the right to block any filing request for an entity whose required Luxembourg national identification numbers were missing. “These restrictions may remain in place until the required information has been duly communicated by the registered entity or its representative, and the situation has been regularised,” emphasised the LBR.

Restrictions could apply to all filing formalities, and the LBR confirmed that access to services would be reinstated immediately once the update had been processed and validated.

For those encountering technical or administrative difficulties, the LBR offers an assistance desk--available by appointment--to help applicants with electronic filing procedures.
