The ACMA is required to maintain the Telecommunications Numbering Plan 1997 (the Numbering Plan) under the Telecommunications Act 1997.
The Numbering Plan provides for the availability, allocation and portability of numbers in Australia, including their use, transfer and withdrawal.
The Numbering Plan covers geographic numbers, freephone numbers (1800), local rate numbers (13, 1300), premium rate numbers (19) and mobile phone numbers.
Geographic numbers are ten digit numbers starting with 02, 03, 07 and 08, which are used for local services in Australia. Geographic numbers contain information about where the service is located, including the state and region, and may give additional information about the general locality of a number.
New geographic numbers are created when a number range has been fully allocated in an area. Stocks of telephone numbers set aside for different areas of Australia run out over time, and new prefixes are introduced to meet demand.
New number ranges are developed in consultation with the ACMA’s Numbering Advisory Committee. The committee is made up of representatives from telephone companies, government bodies and organisations representing consumer and user interests.
