About .lu domain
.lu is the country code top-level domain (ccTLD) assigned to Luxembourg. It is administered by RESTENA through its registry arm DNS-LU, which has managed the extension since its delegation. The domain was introduced on 27 January 1995 and registrations are made directly at the second level, meaning there are no mandatory sub-categories like .co.lu or .org.lu. In September 2006, the registry introduced an accredited registrar model, making it possible to register .lu domains through certified third-party registrars in addition to the classic direct registration route.
Who can register .lu domain
.lu is an open registration extension — both legal entities and natural persons may register a .lu domain, with no requirement to be based in or have any connection to Luxembourg. Since 1 February 2010, even the administrative contact for a domain no longer needs to be located in Luxembourg. Registrants are responsible for ensuring their registration does not infringe on third-party rights, such as trademarks. Domain names that are contrary to public order or that offend common decency cannot be registered.
How to register .lu domain
Search for your desired .lu domain name using a registrar that is accredited by DNS-LU. Confirm the name is available and check that it falls within 1 to 63 characters, using only permitted alphanumeric characters, hyphens (not at the start or end), or supported accented characters.
Compare pricing and features across accredited .lu registrars. Look at both first-year registration costs and renewal rates, and check whether the registrar offers WHOIS privacy, DNS management tools, and customer support in your preferred language.
Complete the checkout process by providing accurate registrant contact details. As the holder, you are certifying that neither the registration nor the use of the domain name will infringe the rights of any third party, so ensure your intended use is legitimate before purchasing.
After registration, verify your contact details are correct in the WHOIS record and configure your DNS settings to point to your hosting provider or name servers. Keep your registrant information up to date, as accuracy is a requirement under the .lu domain charter.
Typical uses of .lu domain
.lu domains are most commonly used by businesses, organizations, and individuals who want to establish a clear local identity in Luxembourg. Companies operating in the Luxembourg market often choose .lu to signal local presence and build trust with customers who expect a country-specific address. Personal websites, professional portfolios, and public-sector entities based in Luxembourg also make use of this extension, and because registration is open to anyone worldwide, international businesses targeting the Luxembourg market register .lu names alongside their primary domains.
Tips for registering .lu domain
- Registration is open to anyone globally, but you are legally responsible for ensuring your domain name does not infringe third-party rights — review any existing trademarks before registering.
- Domain names must be between 1 and 63 characters long and may include accented characters from Luxembourgish, French, and German (such as à, é, ö, ü, and others), giving you flexibility for localized branding.
- Registrations can be made either through an accredited registrar (the preferred and most common route) or via the classic direct registration process with DNS-LU, though the registrar route is generally faster and more convenient.
- Check whether your chosen registrar offers WHOIS privacy, as availability of this feature can vary between providers for ccTLDs.
- Be aware that domain names clearly contrary to public order or common decency are prohibited and may be refused or revoked by the registry.
