The .mu extension is the country-code domain of Mauritius, an island nation in the Indian Ocean with its capital in Port Louis. Hotels, tour operators, financial and professional firms, and local shops use it to show that they are based in Mauritius and to speak to visitors and clients who come to the island. Use the availability form just below this text to see whether your name in .mu is still available.

A short history
Mauritius received its national code in the early years of the internet, when the network was used mainly by universities and government bodies. Over time the island's tourism industry and its service sectors made the zone a common choice for hotels, travel firms and local businesses. Today a .mu address is a regular part of commercial life on the island, from small shops in the towns to larger companies that serve international clients.
Who runs it
The zone is managed by a national registry that maintains the database of names and sets the rules for registration. Registrars sell names to customers and pass the orders to the registry. Because the terms are set nationally, read the current conditions for holders, contact details and renewal before you order, since they can change over time.
Rules in practice
- Holder conditions: the registry may set rules on who can hold a .mu name, so check the current terms and your own eligibility first.
- Contact details: the holder information must be accurate, and the registrar may ask for it to be confirmed.
- Characters: names use letters, digits and hyphens, within the length limits that apply to domain labels.
- Renewal: enable auto-renewal and set reminders for a named person, because a lapsed name can be taken by another applicant.
Who uses .mu
- Hotels, resorts, tour operators and beach restaurants that welcome visitors to the island.
- Accountancy, legal and financial services firms that work with local and international clients.
- Shops, craft makers and food producers that sell to residents and visitors.
- Schools, universities and cultural organisations that serve the island's communities.
Strengths
- The ending points clearly to Mauritius, which helps visitors and partners recognise a business based on the island.
- The address suits sites in English or French, and many people on the island also use Mauritian Creole in daily life.
- The name works well on resort signs, boat tour leaflets and printed travel guides where a short address matters.
Things to keep in mind
- The zone refers to one island nation, so a business with customers across the world may also need a generic address.
- Visitors from many countries may not know the ending, so print the full address on brochures and receipts.
- Good short names are often taken, so consider a name that includes the resort, the town or the activity.
- Rules for holders can change, so keep the registration details current.
Tips before you register
- Search for the name in .com and weigh up whether a second address is worth it.
- Match the holder details to your official records, down to spelling and address format.
- Publish the site in English and French, with clear booking or contact details and a privacy notice.
- Set up SPF, DKIM and DMARC records before sending booking confirmations from the domain.
- Turn on auto-renewal and give access to two trusted people in your team.
Frequently asked questions
Do I have to live in Mauritius to register a .mu name? The registry's conditions decide this, and they may depend on your situation, so check the current terms before you order.
Does a .mu address help a travel site appear in search results? It is one useful signal. Accurate content about the island, clear booking information and genuine references usually matter more.
Can I use Creole on a .mu site? Yes. The ending does not fix the language, and many local sites use English, French and Creole together, depending on their audience.
