Second level domains are for trademark/tradename holders only. Third level domains in ".nom.ad" are for personal use. No indication of cost for the domain but the mandatory trademark registration for commercial domains is 20,000 PTA. 3 domains per person. Domains cannot be transferred. Using a domain name ending in .ad invokes the "Law on the use of state emblems and signs" and an application for authorisation must be filed with the ministry in charge of authorisations for use of State signs.
