About domain names


A domain name is a combination of an address and an online identity. The ability to register and use domain names has facilitated the global development of the internet and created the means for people who lack specific technical knowledge to use the internet.

A domain name is an address to a server on the internet in a format that people can remember, such as regeringen.se (thegovernment.se). You could say that a domain name is a pseudonym for the IP addresses that machines communicate with – for example, is the same address as www.regeringen.se.

The same applies to e-mail management. You do not need any complicated numerical codes to send your e-mail to a friend. Instead, you generally just write name.surname@example.se or something similar.

Your online identity

Your domain name is your online identity, regardless of whether you use it as a private website, your company website or for a personal e-mail address. According to a survey conducted by IIS, the most common reasons for obtaining an independent domain name were as follows – please note that several reasons could be given.

  • For website (75%)
  • For a personal, independent e-mail address (33%)
  • To prevent others from registering the domain name (protective registration) (13%)
  • To blog (7%)
  • To resell the name (4%)
  • Other (31%)

A .se domain must contain at least two and not more than 63 characters.

A .se domain can include the letters a-z, å, ä, ö, é and ü, the numbers 0-9, hyphens and any of the characters in the official Swedish minority languages or those of our Nordic neighbors, which are known as IDN domains. Read more about IDN domains here.

A good domain name is a name that works for you and those with whom you want to communicate. Regardless of whether you are a private person, an association or a company, a good name should express your online identity and be easy to remember.
