In the case a Youth Business (studentbedrifter) wants to register a .NO domain, they have to use a subordinate to uenorge.no. For example: youthbusiness.uenorge.no. Below you'll find a detailed explanation by the registry.
Youth Businesses (studentbedrifter) may only register domains within the category domain uenorge.no, like youthbusiness.uenorge.no
The applicant must be a Youth Business (Ungdomsbedrift) or a Student Business (Studentbedrift), and must be a part of Ungt Entrepenørskap’s teaching plan for high school or college education.
If this is not the case, the registrant can consider registering the domain as a private individual.
