English is the official language, and Roseau is the capital. Tour operators, guides and community projects on the island use .dm to show a local link.

A short history
The national code was set up in the early days of the internet, and the zone grew as island businesses, schools and public bodies began to publish websites. Dominica is known as the Nature Island of the Caribbean for its rainforest and volcanic landscape, and that makes the ending a good fit for nature and tourism projects. The operator's own information is the most reliable source for current dates and rules.
Who runs it
The zone is managed by a registry operator that keeps the database of names and sets the rules for registration. Registrars sell names to customers and send the orders to the registry. The operator's published terms cover eligibility, contact details and renewal, and they should be read before you pay, since they can be updated.
Rules in practice
- Holder conditions: the operator may set conditions on who can hold a .dm name, so check the current requirements first.
- Contact details: the holder data must be correct, and the registrar may ask you to confirm it.
- Characters: names use letters, digits and hyphens, and each label can be up to 63 characters long.
- Renewal: keep the expiry date in view and enable auto-renewal, so that the name stays with your project.
Who uses .dm
- Eco-lodges, hiking guides and tour operators that take visitors into the rainforest, to the lakes and to the waterfalls.
- Restaurants, shops and craft producers in Roseau and in the villages.
- Schools, environmental groups and research projects that work on the island's nature.
- Transport services that welcome visitors arriving by sea or by air.
Strengths
- The ending links the site to Dominica at a glance, which helps visitors planning a trip find the right address.
- The name is short and easy to read on a trail map, a roadside sign or a boat.
- English is the official language, so a site in English can reach local and international visitors at once.
Things to keep in mind
- Dominica is a different country from the Dominican Republic, which uses .do. Visitors may mix up the two endings, so state the country clearly on the home page.
- The ending points to one island, so a business that serves a wider audience may need a generic address too.
- The letters DM are also used on social networks for direct messages, so check how the address reads in that context.
- Holder rules can change, so check the current terms before you renew.
Tips before you register
- Check the name in .com and in the social profiles you plan to use.
- Register under the legal name of the business and keep it consistent on the site and on invoices.
- Publish trail, tour and safety information clearly, since visitors rely on it before they set out.
- Set up SPF, DKIM and DMARC records before the domain sends bookings or newsletters.
- Set a renewal reminder in two calendars and keep a second contact who can act if the owner is away.
Frequently asked questions
Is .dm the same as .do? No. Dominica uses .dm, and the Dominican Republic uses .do. They are separate countries, so the endings are not interchangeable.
Do I need to live in Dominica to register a .dm name? Holder conditions may apply. Check the current terms at the time of the order.
Does .dm help a tourism site rank in search results? It is one geographic signal. Clear descriptions of tours, reliable details and genuine links usually matter more.
