Australian geographic numbers begin with 02, 03, 07 or 08. This map shows a broad state-level overview of the four numbering regions; local numbering areas cross state borders in several places.
How to read the map. The four geographic prefixes are 02 Central East, 03 South East, 07 North East and 08 Central and West. Mobile numbers beginning 04 are not geographic. The fills group whole states and territories for a national overview; they are not exact numbering-area boundaries.
Where the numbering regions actually run. The 2025 Telecommunications Numbering Plan specifies codes by standard zone units and charging districts. It assigns 02 to most of New South Wales, the ACT and parts of northern Victoria; 03 to Tasmania, most of Victoria and parts of southern NSW; 07 to Queensland; and 08 to WA, SA, NT and parts of western NSW. The map uses state boundaries, so border localities can differ from the fill. Christmas Island and the Cocos (Keeling) Islands also have 08 numbers, but are not drawn in the state-boundary layer.
