Interim

National Numbering Plan

For Anguilla

Introduction

Anguilla (country code +1 264)

The Telecommunications Act 2003 stipulates under section 31 that the Minister shall develop a plan for the numbering of telecommunications services and shall administer and manage such numbers.

Under Part 1 Section 3 (1) of the Telecommunications Numbering Regulations 2004, “The National Numbering Plan to be issued by the Minister identifies the framework for allocation of ordinary numbering blocks, exchange codes, short codes, and other unique numbering resources to different classes of Resource Users and applications”.

The Minister of Infrastructure, Communications, Utilities and Housing (MICUH), the Valley, Anguilla, announces the following Interim National Numbering Plan for Anguilla.

Anguilla is in the World Zone 1 (WZ1) Plan, Country Code = “1”, NPA = 264.

The 10-digit North American Numbering Plan (NANP) area address is made up of three parts, in the format NXX-NXX-XXXX:

· The first group of three characters (NXX) is the Numbering Plan Area Code (NPA);

· The second group of three characters (NXX) is the Central Office Code (CO Code); and

· The third group of characters (XXXX) is the subscriber’s line number. In the above format NXX-NXX-XXXX: N = 2 to 9 and X = 0 to 9).

The dialling format for the 264 NPA is as follows:

All home NPA (HNPA), local calls will be dialled on a seven-digit basis with no prefix, i.e.: NXX + XXXX, e.g. 497 1234, where 497 is the NXX, and 1234 is the subscriber number (SN).

All Foreign NPA (FNPA), direct dialled calls will be dialled with a prefix “1” + ten digits”, i.e.:

1 + NPA + NXX + Subscriber Number (SN).

For example: 1 + 264 + 497 +1234, where 1 = Prefix
264 = NPA
497 = NXX
1234 = SN

Resource allocation or numbering is no longer a viewed as a purely technical matter but increasingly as an issue which must address important commercial, political, and economic considerations for telecommunications operators, regulators and policy makers. As a result it is foreseen that the PUC and the Government will have to continually engage in a continuous process of revision of any Numbering Plan that is implemented.

Central Office Codes

This document outlines the current allocation of Central Office (CO) codes within the Numbering Plan Area (NPA) Code “264”. Note the use of the word “allocation” intentionally to differentiate between it and “assignment”. To allocate a numbering resource is to identify its intended use, e.g., geographic, wireless, special services, by the telecommunications sector. To assign a numbering resource is to reflect the allocation by actually assigning a specific block(s) of the resource to service providers to use for the stated purpose (allocation).

These allocations are based on the premise that “achieving the objective of clearly distinguishing the type of service is more important than distinguishing the specific company providing the service”.

Central Office Codes are a part of the NANP telephone number format. They are assigned only to identify initial destination addresses in the Public Switched Telephone Network (PSTN), not addresses within private networks. Examples of uses for CO codes include plain old telephone service (POTS), Centrex, Direct Inward Dialling (DID), cellular mobile service, pagers, data lines, facsimile, coin phones, and customer owned pay phones.

Short Codes for Special Services

A set of codes is traditionally set aside for “special services”. Typically, the codes selected for allocation to special services are codes that are easily recognizable by subscribers.

These Easily Recognizable Numbers (ERCs) are codes of the N00 any YYY formats. Such codes are normally used for special services. Such services would typically be value-added services, charged at special rates or premium rates, with or without content.
