The .dk extension is the country-code domain of Denmark, a Scandinavian kingdom whose capital is Copenhagen. For a company or project that serves Danish customers, a name in .dk shows at once where it is based and who it is for. Visitors in Denmark tend to recognise the ending straight away. Use the availability form just below this text to see whether your name in .dk is still free.

A short history
Denmark received its national code in the early years of the internet, when universities, research institutions and technology firms were among the first to use the network. As Danish companies moved online, the zone grew to cover shops, design studios, craft workshops and public bodies. Over time .dk became a normal part of Danish business life, and its rules have been revised as the zone developed, so the current terms are the ones to read before you order.
Who runs it
The Danish zone is run by DK Hostmaster, which operates the central register of .dk names and the systems behind them. Accredited registrars sell names to customers and pass the orders on to the registry. The registry publishes its rules for holders and for the registration process, and those rules are the reference point for any question about eligibility, contact data or renewal.
Rules in practice
- Holder conditions: the registry sets rules on who may hold a .dk name, and these can depend on the holder's connection to Denmark. Check them before you pay.
- Contact data: the details you give must be accurate and up to date, and they may be checked when the registry asks.
- Letters and length: names use letters, digits and hyphens, and a single label can be up to 63 characters long.
- Danish letters: letters such as æ, ø and å may be possible through internationalised names, depending on the current rules.
Who uses .dk
- Danish companies of every size, from sole traders to established firms.
- Shops, cafés, design studios and craft workshops that sell to Danish customers.
- Associations, clubs and cultural projects with a Danish audience.
- Consultants, freelancers and service providers who work mainly in Denmark.
Strengths
- The ending makes the Danish focus of a site clear, which helps local visitors feel that a business is close to them.
- Search engines can treat a country-code ending as one hint about the intended audience, so Danish-language content may match local searches well.
- The zone is familiar in Denmark, so it needs little explanation on a business card, a van or a shop window.
Things to keep in mind
- A .dk name ties the project to Denmark, so a business with mostly overseas customers may also want a generic address.
- Visitors in neighbouring countries may expect their own endings, so think about who will actually type the address.
- Short and simple names are often taken, so prepare two or three alternatives before you start.
- Holder rules and contact requirements can change, so keep your registration details current.
Tips before you register
- Check whether the same name is free in .com and decide whether a second address is worth owning.
- Write the company details exactly as they appear in your official papers.
- Set up SPF, DKIM and DMARC records before the domain is used for e-mail or invoices.
- Publish clear contact and company information on the site, so that the domain and the content tell the same story.
- Turn on auto-renewal and protect the registrar account with two-factor login.
Frequently asked questions
Do I have to live in Denmark to register a .dk name? Holder conditions apply, and they can depend on your situation. Check the current terms at the time of the order.
Does .dk help a site appear in Danish search results? It is one useful geographic signal. Clear Danish content, fast pages and relevant local links usually matter more.
Can I write a .dk name with æ, ø or å? Possibly, through internationalised names, but the registry rules decide. Check how the address displays in your e-mail programme before you rely on it.
