12、ondence services. Further, ithas been determined that three-digit Trial Identification Codes (TICs) will be temporarily assignedto successful applicants for the duration of their specified trial activity. This Recommendationdefines the use and limitations of such a resource as well as the criteria a
13、nd procedures for thetemporary assignment and reclamation of TICs.2ScopeThis Recommendation contains the criteria and procedures for an applicant to be temporarilyassigned a three-digit identification code within the shared E.164 country code 991 for the purposeof conducting an international non-com
