Phone number meanings

Numbers for telephone services can give you information about certain aspects of the service you are calling. For example, an area code such as (02), (03), (07) or (08) at the beginning of a number indicates it is a regular geographic telephone number, whereas an '04' prefix indicates that the service is a mobile phone.

Australia's Telecommunications Numbering Plan 1997 ensures telephone companies use the same approach to the use of telephone numbers. This means you can recognise a certain telephone number is associated with a specific type of service and call cost.

The table below gives information about special services (using numbers other than regular telephone numbers) provided by telephone companies.
