National Numbering Plans

Administrations are requested to notify ITU about their national numbering plan changes, or to give an explanation of their web page on national numbering plan as well as their contact points, so that the information, which will be available freely to all Administrations/ROAs and service providers, can be posted on ITU-T website.

Administrations are requested to use the format as explained in the ITU-T Recommendation E.129 for their numbering website, or when sending the information to ITU/TSB; e-mail: tsbtson@itu.int.

ITU-T website and the ITU Operational Bulletin (http://www.itu.int/pub/T-SP/e) are the authoritative sources for ITU-T E.164 numbering information (the so called telephone numbering plan).

WTSA-16 approved Resolution 91 recognized that reliable information about reserved and assigned Numbering, Naming, Addressing and Identification (NNAI) resources for each country is an important issue for ensuring global telecommunication interconnectivity. Enhancing electronic access to a repository of information on numbering plans with numbering resources reserved or assigned to each operator/service provider (to the extent available) within every country, would be advantageous for ITU Member States and international telecommunication operators or operating agencies, to help improve the reliability of telecommunication networks and services they carry and help improve revenue assurance for operators, and may assist in countering misuse of international telecommunication numbering resources.
