SITA is required by both ICANN and the aviation community to maintain the integrity of .aero in order to ensure that it is a trusted domain to do business.
Unlike very generic Top Level Domain Names, the integrity of .aero is maintained through verification of all registrants who submit a .aero name request to a registrar. SITA verifies each potential .aero registrant and ensures that they are a valid member of the aviation community, before issuing them an aviation community membership ID. This verification significantly decreases the volume of speculative registrations and cybersquatting, but generates a cost. Although it has an impact on the price of a .aero domain name, it is thanks to this process that .aero benefits from the support of aviation industry associations and their members.
Other specialized Top Level Domains such as .coop and .museum, operating under a contract similar to the one for .aero, have similar or even higher pricing.
