Editing E.164 (section)

==Recommendations==
===E.163===
E.163 was the former [[ITU-T]] recommendation for describing [[telephone]] numbers for the [[public switched telephone network]] (PSTN). In the United States, this was formerly referred to as a ''directory number''. E.163 was withdrawn, and some recommendations were incorporated into revision 1 of E.164 in 1997.<ref>{{Cite web|url=https://www.itu.int/rec/T-REC-E.163|title=E.163 : Numbering plan for the international telephone service|website=www.itu.int|url-status=live|archive-url=https://web.archive.org/web/20190729130203/https://www.itu.int/rec/T-REC-E.163|archive-date=2019-07-29|access-date=2019-11-12}}</ref>

===E.164.1===
This recommendation describes the procedures and criteria for the reservation, assignment, and reclamation of E.164 country codes and associated ''identification code'' (IC) assignments.<ref>{{Cite web|url=https://www.itu.int/rec/T-REC-E.164.1|title=E.164.1 : Criteria and procedures for the reservation, assignment and reclamation of E.164 country codes and associated identification codes (ICs)|website=www.itu.int|url-status=live|archive-url=https://web.archive.org/web/20191112172208/https://www.itu.int/rec/T-REC-E.164.1|archive-date=2019-11-12|access-date=2019-11-12}}</ref> The criteria and procedures are provided as a basis for the effective and efficient utilization of the available E.164 numbering resources.

===E.164.2===
This recommendation contains the criteria and procedures for an applicant to be temporarily assigned a three-digit identification code within the shared E.164 country code [[+991|991]] for the purpose of conducting an international non-commercial trial.<ref>{{Cite web|url=https://www.itu.int/rec/T-REC-E.164.2|title=E.164.2 : E.164 numbering resources for trials|website=www.itu.int|url-status=live|archive-url=https://web.archive.org/web/20191112172324/https://www.itu.int/rec/T-REC-E.164.2|archive-date=2019-11-12|access-date=2019-11-12}}</ref>

===E.164.3===
This recommendation describes the principles, criteria, and procedures for the assignment and reclamation of resources within a shared E.164 country code for groups of countries.<ref>{{Cite web|url=https://www.itu.int/rec/T-REC-E.164.3|title=E.164.3 : Principles, criteria and procedures for the assignment and reclamation of E.164 country codes and associated identification codes for groups of countries|website=www.itu.int|url-status=dead|archive-url=https://web.archive.org/web/20191112172813/https://www.itu.int/rec/T-REC-E.164.3|archive-date=2019-11-12|access-date=2019-11-12}}</ref> These shared country codes will coexist with all other E.164-based country codes assigned by the ITU. 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. The Secretariat of the ITU Standardization Sector ([[ITU-T]]), the Telecommunication Standardization Bureau (TSB) is responsible for the assignment of the CC + GIC.
