NaN overview

Numbering is a key enabler of communications services and national numbering plans have evolved to facilitate competition and service innovation for new and existing market players while maintaining an appropriate level of consumer protection. On the network side, appropriate policies are required to ensure a seamless transition to next generation networks, which will provide capacity and speed for the applications and services that consumers will demand now and in the future.


The CEPT's Electronic Communications Committee (ECC) and the ECO have been actively involved in assisting National Regulatory Authorities to pursue these objectives during the process of liberalising electronic communications markets in Europe, as well as in the new environment that is emerging from the convergence of the traditional electronic communications market and the Internet.

Harmonisation of national numbering plans and policies is necessary to assist citizens travelling in an increasingly integrated Europe to stay connected with ease and at a reasonable cost. A good example of harmonisation is the single European emergency number 112 which allows European citizens to contact emergency assistance no matter where they are in Europe on a single common number. CEPT's Long Term Standardisation of National Numbering Plans (Recommendation T/SF 1) originating from 1972 was a seminal document which started the process towards making pan-European 112 a reality. The harmonisation initiatives of this recommendation have since been enshrined in ECC Decision (17)05 on Harmonised Prefixes and Short Codes in National Numbering Plans.
