Choose your phone number

You can ask your telco to give you a specific phone number for your personal use. You can also buy a custom number for your business. 

Types of phone numbers

There are 6 main types of phone numbers in Australia:

Geographic numbers are mainly for local or landline services. They have 10 digits and start with one of the following:

Smartnumbers are catchy numbers that make it easier for people to remember a business. Smartnumbers have one of the following:

Register for updates from our numbering system to learn about changes to numbers. For example, when we release the new 05 number prefix for mobile phone services.

You can check which telco has numbers at the Numbering System.

Choose a personal number

Ask your telco if you want:

  • a specific number to use straight away
  • to reserve a number to use in the future

Your telco does not have to agree to your request.

Calling line identification (CLI)

Your CLI is the number that is shown to the person being called when you make a call. You can make your phone number more private if you don’t want this number to be displayed.

Some businesses want to display a particular number as the CLI when they call customers. This makes make it easy for customers to identify them and call back.  This is called ‘CLI overstamping’, and it is legal in Australia—as long as it is not being used for phone scams

Talk to your telco if you want to use your particular number when making outgoing calls to customers.

In December 2020, we registered Industry Code C661:2020 Reducing Scam Calls. It includes new CLI rules for carriers and carriage service providers to help identify, block and reduce scam calls.

Use phone numbers for fiction

Do not use real phone numbers in radio, books, films and television as people often call them.

We have phone numbers you can use for the work you publish or broadcast.

You can use these numbers for fictional purposes. This includes premium rate, geographic, mobile or freephone and local rate numbers.
