In order to be a domain subscriber, you have to be registered as an organisation in the Brønnøysundregistrene (the Norwegian central organisation registry). Here you can find an overview of relevant organisation types . The organisation applying for a domain name must previously be registered with an organisation number. In addition, the organisation has to have an address in Norway or in Svalbard. If the enterprise exists only outside of Norway, it cannot apply for domain names under .no.

An organisation can subscribe for up to 20 domain names under the .no domain. In addition, it can register up to 5 domain names under different suitable categories and up to 5 domain names for each geographical area to which the organisation belongs.
