Before starting a business or setting up a company, entrepreneurs can check the availability of the commercial brand name or company name they plan to use.
The availability request can be submitted online to the Luxembourg Business Registers (LBR).
When the request has been processed, the entrepreneur has 20 days to download the certificate of availability ("libre") or unavailability ("non libre").
Carry out your procedure:

- Certificat de disponibilité de dénomination
Applications for certificates confirming the availability of business names are subject to the payment of administrative costs.
These costs are laid down in the RCS table of tariffs.
Application for a certificate of availability
The entrepreneur can check the availability of the company name (brand name or business name) that he wishes to use for his business by submitting an application for a certificate confirming the availability of the company name (electronically) to the Luxembourg Business Registers (LBR).
NB: a trader that is a natural person who uses a trading name must add information concerning his surname and first names.
Downloading the certificate
When the certificate is available, the applicant can be notified by email. The certificate can be downloaded in PDF format during a period of 20 days from the personal space of the applicant on the website www.rcsl.lu. The PDF documents can under no circumstances be delivered by email.
The certificate confirms the availability or not of the company name or names requested with respect to the business names already registered with the RCS.
There are 2 possible responses from the LBR:
- a 'certificate of unavailability of the company name' confirms that the name requested is not available and that another person is already registered under this name. Only the deregistration from the RCS of a registered legal or natural person makes a company name available again;
- a 'certificate of availability of the company name' is issued if the name requested has not yet been registered with the RCS. The certificate is valid as soon as it is issued but only until the name is officially registered with the RCS. However, it does not mean that the name in question is now reserved and it does not prevent another person from registering the same name meanwhile on his own behalf.
The certificate of availability of the company name does not allow the reservation of the name concerned. Any name available can be taken by the first person who submits an application for its registration with the RCS.
