The .se extension is the country-code domain of Sweden, a Nordic country with Stockholm as its capital and Swedish as its main language. Swedish companies, schools, cultural projects and local services use it to show that they are rooted in Sweden. It tells visitors and search engines that a site is aimed at a Swedish audience. Use the availability form just below this text to see whether your name in .se is still free.

A short history
Sweden received its national code in the early years of the internet, when universities and technology firms were among the first to register names. As Swedish businesses and public bodies moved online, the zone grew to cover everything from large companies to family firms, sports clubs and cultural associations. Its rules have been updated over time, so the current terms are the ones that matter when you place an order.
Who runs it
The .se zone is managed by IIS, the Internet Infrastructure Foundation, a non-profit foundation based in Sweden. IIS operates the registry, keeps the database of names and sets the rules that apply to holders, while registrars sell names to customers and send orders to the registry. Because the foundation publishes its terms openly, they are the best reference when you have a question about registration or renewal.
Rules in practice
- Holder rules: the registry sets conditions on who may register and hold a .se name, so check the current rules before you pay.
- Contact details: the information you give must be accurate, and it may need to be confirmed when the registry asks for it.
- Length and characters: names use letters, digits and hyphens, and a single label can be up to 63 characters long.
- Swedish letters: letters such as å, ä and ö may be possible through internationalised names, depending on the current rules.
Who uses .se
- Swedish companies of every size, from sole traders to large groups.
- Restaurants, hotels and shops that serve customers in Sweden.
- Schools, sports clubs, choirs and cultural associations with a Swedish audience.
- Designers, consultants and tradespeople who want a clear local address for their clients.
Strengths
- The ending gives a clear signal of a Swedish base, which helps local visitors recognise the business quickly.
- Search engines can treat a country-code ending as one geographic hint, so Swedish-language content may match local searches.
- The zone is familiar and reads well on signs, vehicles and printed material, so it needs little explanation.
Things to keep in mind
- A .se name points to Sweden, so a business that mainly serves Norway, Denmark or Finland may want to consider other endings too.
- Visitors from other countries may type .com out of habit, so decide whether owning both is worth it.
- Good short names are often registered already, so think about a descriptive wording.
- Holder rules can change, so keep your registration details up to date.
Tips before you register
- Check the name in .com and in the Nordic zones you may need, and decide which ones matter for your audience.
- Enter the company details exactly as they appear in your official registration.
- Publish Swedish content, contact details and the information your customers will look for first.
- Host the site close to Swedish visitors so that pages load quickly.
- Set up mail records before you send invoices or newsletters from the domain.
Frequently asked questions
Do I need to be based in Sweden to register .se? Holder conditions apply and can depend on your situation, so check the current terms at the time of the order.
Does a .se name suit a company with customers in several Nordic countries? It can, but the ending points to Sweden, so a wider Nordic audience may be better served by a generic address.
Will a .se name help my site appear in Swedish search results? It is a helpful location signal, but relevant content, fast pages and genuine local references usually matter more.
