Regulation 11 Numbering
In exercising their functions under the Act the Secretary of State and the Director shall take into account the need to:
ensure the provision of adequate numbers and numbering ranges for all publicly available telecommunications services;
ensure that the procedures for allocating individual numbers or numbering ranges or both are transparent, equitable and timely and that the allocation is carried out in an objective, transparent and non-discriminatory manner. The Secretary of State and the Director may lay down conditions for the use of certain prefixes or certain short codes, in particular where these are used for services of general public interest;
encourage the earliest possible introduction of the number portability facility whereby end-users who so request can retain their numbers on the fixed public telephone network at a specific location independent of the organisation providing service. In order to ensure that charges to consumers are reasonable the Director shall ensure that pricing for interconnection related to the provision of this facility is reasonable.
ensure that numbering plans and procedures are applied in a manner that gives fair and equal treatment to all providers of public telecommunications services and, in particular, to ensure that an organisation allocated a range of numbers shall avoid undue discrimination in the number sequences used to give access to the services of other Public Operators.
The Director shall ensure that the main elements of the national numbering plans, and all subsequent additions or amendments to them, are published in accordance with regulation 8(1), subject only to limitations imposed on grounds of national security.
