Protection and watch areas

Forecasting number runout

The ACMA is responsible for the administration of the Telecommunications Numbering Plan 1997 (the Plan). The Plan provides the structure and policies by which telephone number allocation, issue and use is governed. The ACMA manages the geographic numbering resource so as to ensure that end-users have access to a local telephone service and that the telecommunication industry has access to an adequate supply of numbers with which customers can access its networks and services.  As demand on the numbering resource increases through population growth, the introduction of new technologies and services, and the high rate of telephony penetration in Australia, the ACMA manages the numbering resource so as to ensure that supplies are sufficient to meet the current and future numbering needs of Australia. 

The former ACA as part of its responsibilities under the Telecommunications Numbering Plan 1997 began the process of developing improved geographic number utilisation forecasting and planning techniques to facilitate more efficient use of this valuable resource.

This process is undertaken to assist in the efficient and effective allocation of geographic numbers to carriage service providers. In addition the process will assist in identifying the need for conservation strategies for specific number ranges close to exhaustion, and the need for additional number ranges. Special allocation arrangements apply to protection and watch areas.

Protection areas

The former ACA recognised a number of areas throughout Australia where specific geographic number ranges will be approaching exhaustion during the next two years, and has initiated procedures to contend with the problematic ranges. Number ranges approaching exhaustion in the next 18 months have been identified and are classified as Protection Areas. Specifically, the following Protection Areas have been identified:

Prefix

(03) 62 Geeveston, Hobart, Oatlands, Ouse 1,000,000 933,000 93% 67,000

Number watch areas

The former ACA instituted a system whereby areas which are in danger of running out of numbers in the next 18 months to 5 years, are identified. These ranges are classified as number watch areas. Number watch areas may be upgraded to protection areas if the need to do so becomes apparent. The utilisation of information from carriage service providers assists in determining if there is a need to upgrade Number Watch Areas to Protection Areas.
