These shared Country Codes coexist with all other E.164-based Country Codes assigned by ITU-T. The resource of the shared Country Code consists of a Country Code and a Group Identification Code (CC + GIC) and provides the capability for a Group of Countries to provide telecommunication services within the Group of Countries. TSB is responsible for the assignment of the CC + GIC. Source ITU-T Recommendation E.164.3 was prepared by ITU-T Study Group 2 (2001-2004) and approved under the WTSA Resolution 1 procedure on 14 September 2001. History This version is the first issue of ITU-T Rec. E.164.3. ITU-T Rec. E.164.3 (09/2001) i FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operat
