Which characters are allowed in a .se or .nu address? And which domain names are not possible to register? Here we have collected the terms and conditions that are good to know when you are registering a domain.
The registration terms are the agreement that applies to all domain name holders.
The registration of .se and .nu domains is done through any of The Swedish Internet Foundation’s retailers, so called registrars. Regardless of which registrar you choose, The Swedish Internet Foundation’s terms and conditions apply. There terms are included in all registrar agreements. In addition, each registrar has his or her own terms.
- Anyone can register a .se or .nu domain provided it is available and does not appear on The Swedish Internet Foundation’s block list (see below). The registration of the domain name occurs immediately.
- The chosen name cannot conflict with the law or infringe on the rights of others, such as a trademark.
- The holder must provide a working email address and full contact details.
- A .se or .nu domain may contain at least one and at most 63 characters.
Accepted characters for .se domains
A .se domain can contain the characters a-z, 0-9, hyphens, as well as å, ä, ö, ü and é. All characters in the official Swedish minority languages (Finnish, Meänkieli (Tornedal Finnish), Sami, Romani and Yiddish) can be used. It is also possible to handle the other Nordic countries’ language characters. A complete list of over all 240 characters currently available to use in .se domains can be found in the character table below. Read more about IDN.
Accepted characters for .nu domains
A .nu domain can contain the characters a-z, 0-9, hyphens, and å, ä, ö, ü and é. A large number of characters in other Western European languages, Swedish and some of the other Nordic languages are supported. A complete list over all 69 characters currently available to use in .nu domains can be found in the table below. Read more about IDN.
Blocked and reserved domain names
There are a number of categories of domain names that are blocked or reserved by The Swedish Internet Foundation. See below:
- Number combinations in the format xxxxxx-xxxx that constitute or may be a personal identity number. The block was introduced after a recommendation from the Swedish Data Protection Authority in order to protect people’s personal integrity.
- Two letters followed by two hyphens. The syntax containing two letters followed by two hyphens is reserved for internationalized domain names and is blocked in accordance with current standards to avoid common domain names being perceived as IDN domain names.
- Some domains are reserved as example and test domains and therefore are not possible to register.
- Designations according to the law (1953:711) about protection for certain international health care designations and more (the law is sometimes called the Red Cross law) and the law (1970:498) about protection of weapons and certain other official designations with the associated regulation (1976:100) cannot be freely used and are therefore blocked. The organization that holds the right to the name can register the domain name by proving its right to the name and verifying the right to represent the organization, unless otherwise stated in the relevant legislation. If someone other than the holder requests the cancellation of the block, the applicant must be able to prove that he or she has the approval of the organization concerned. One condition is that something else is not stated in the current legislation.
- Main domains, such as county letters, are blocked for new registrations (only for .se domains). Already registered domain names under a main domain continue to be registered as long as they are renewed.
