Technical contacts are created by the domain holders. Technical administrators can only perform the functions of the domain’s technical administration in the account. They have no access to the initiation of the procedures of billing, transfer of the registrar or domain trade and management of other functions. Technical contacts are used for contacts on the technical issues arising with regards to a specific domain.
