Applying for a registration number

This page was last modified on 02-02-2018

Vehicles that are subject to registration must be fitted with number plates before they can be driven on public roads.

Under the Luxembourg system, there are 2 types of registration number:

  • numbers from the current series, which are attached to the vehicles themselves and stay with them throughout their lifetime;
  • personalised registration numbers, which remain in the name of their holders, unless they give them up so they can be assigned to another person.

It is forbidden to change the registration number of a vehicle that is already registered in a person's name.

An exception is made if the number plate was stolen.

Who is concerned

Businesses concerned

All information provided hereafter is aimed at:

  • businesses who wish to register a car in the name of the company;
  • professionals in the automotive industry.

Professionals in the automotive industry are considered to be car dealerships, car rental businesses, vehicle registration service providers or transport companies.

Vehicles concerned

Anyone residing in Luxembourg must apply for a registration number when registering a vehicle falling in one of the following categories:

  • cars;
  • vans;
  • tricycles and quadricycles;
  • trailers;
  • caravans;
  • mobile homes;
  • machinery;
  • buses and coaches;
  • lorries;
  • tractor units and articulated lorries;
  • motor-homes and camping-cars;
  • mopeds;
  • light quadricycles.

Required registration

In the following cases, a new registration number must first be applied for before the vehicle can be registered:

  • registration of a new vehicle;
  • purchase/registration of a vehicle registered in a another country;
  • purchase of a vehicle already registered in Luxembourg under a personalised registration number belonging to the former owner;
  • purchase of a vehicle registered under a number with the old format (2 letters and 3 digits or 1 letter and 4 digits);
  • re-registration of a vehicle.

Preliminary steps

In order to access the online application form, professionals in the automotive industry must first have their professional eSpace certified for professionals in the automotive industry by the National Society of Automotive Traffic (Société nationale de circulation automobile - SNCA).

To certify the business eSpace, the persons concerned must complete the online procedure for the certification of a business eSpace and attach:

  • a certificate from the employer specifying that the employee has power of signature and acts in the interest and on behalf of the company (scanned document in PDF format);
  • a copy of the company's business permit (scanned document in PDF format).


The reservation of registration numbers is free of charge.

To register a vehicle with a number from the current series, applicants must purchase a government tax stamp in the amount of EUR 50.

When registering the vehicle with a personalised registration number, the following extra charges apply:

  • EUR 50 if the number is being used for the first time;
  • EUR 24 if a number is being reused by the same owner.
The tax is due only at the time of registering the vehicle.

Changing the number on the registration certificate is free of charge if the number plate was stolen. However, the cost of the new number plate is borne by the applicant.

How to proceed

Applying for a registration number by a professional in the automotive industry

The reservation of a registration number from the current series by a professional from the automotive industry can be made online with the assistant.

Clients of professionals from the automotive industry can reserve their personalised registration numbers via the online procedure without LuxTrust authentication (except for applications for a 4-digit number plate) by completing the application with the details of the person in whose name the vehicle will be registered.

Application for a registration number by all other businesses

Registration number from the current series

The application for a registration number from the current series can be filed:

The registration number assigned to a person is the first one available in the current series.

The numbers in the current series are composed as follows:

  • 2 letters and 2 digits for mopeds or light quadricycles;
  • 2 letters and 4 digits for all other vehicles.

Personalised registration number

There are 4 distinct series of personalised registration numbers:

  • for mopeds or light quadricycles: 2 letters and 2 digits;
  • for all other vehicles:
    • a 5-digit number;
    • 2 letters and 4 digits; or
    • a 4-digit number.

The reservation of a personalised registration number has to be carried out with the online assistant with authentication or without authentication.

Re-using a personalised registration number on another vehicle

Personalised registration numbers that are currently being used for a registered vehicle can automatically be kept by their holder and transferred to another vehicle, provided that the current vehicle is taken off the road (deregistration).

The number remains assigned to its holder for 36 months after the vehicle has been taken off the road. At the end of that period, if the holder has not registered another vehicle under the same number, the number will revert to the SNCA and will become available to another applicant.

Number plates for vintage vehicles and other number plate formats

The appearance of number plates may vary, depending on the date of initial registration of the vehicle.

If it is technically impossible to mount a European-format number plate on a vehicle, the owner/holder of the vehicle in question may use a plate with a different format. In such cases, the vehicle owner/holder is advised to file an online application with the SNCA, accompanied by a photograph, to find out what specific conditions apply.

Manufacturing of the number plate

Once a registration number has been reserved, the ministerial authorisation for the assignment of the number is sent to its holder by post.

Once the registration number has been assigned, the person concerned must contact a Luxembourg-registered number plate manufacturer to have the plate made.

If a number plate is damaged or deteriorated, it is recommended that it be replaced.

Transferring a personalised registration number

The current holder of a personalised registration number may transfer the number to another person for the purpose of registering a vehicle with the number in question.

When the holder of a personalised registration number dies, their heir, parent or first-degree relative is entitled to keep the personalised registration number.

The transfer of a personalised registration number is still subject to payment of the applicable regulatory tax.

The transfer of a personalised registration number must be completed before the number can be used to register a vehicle. The transfer can be made by sending a completed "Transfer of a registration number" form (Transfert d'un numéro d'immatriculation) via email, signed by both parties concerned and accompanied by a copy of their identity document, to the National Society of Automotive Traffic (SNCA,

Once transferred, a personalised number will remain assigned to its new holder for 36 months. At the end of that period, if the new holder has not used the number to register a vehicle, the number will revert to the SNCA and will become available again for other applicants.

Theft of a number plate

If a number plate is stolen, the owner or holder of the vehicle must report the theft to the Police, who will record a declaration of theft or a complaint.

The owner/holder must then apply for a new registration number as soon as possible to replace the current one.

Using a vehicle without a number plate may lead to a fine.

To change the number on the certificate, applicants must send or bring the following documents to the National Society of Automotive Traffic (SNCA):

  • the completed and signed registration certificate application form;
  • where applicable, the tax stamp;
  • a valid insurance certificate, established by an insurance company accredited in Luxembourg and bearing the new registration number;
  • the declaration of theft established by the Police;
  • parts 1 and 2 (grey and yellow respectively) of the registration certificate;
  • a valid roadworthiness inspection certificate, if the vehicle is covered by one;
  • a copy of the vehicle owner's/holder's identity document;
  • the owner's written consent to have the number replaced, if the applicant is the holder of the vehicle.

The person submitting the registration documents to the SNCA must produce their identity card. If the application is being submitted by a third party, they must produce a power of attorney. In that case, it is important to ensure that the name of the vehicle's owner or holder, and not that of their representative, appears on all the documents.

The old number will be considered unassigned for 5 years from the presumed date of the theft. Nevertheless, it will still be reserved for the owner or holder of the vehicle in question.
