Australian business phone numbers: area codes, 13/1300 and 1800
Setting up in Australia? Learn the area codes, mobile numbers and 13, 1300 and 1800 numbers, and which type suits your business.
On this page
Australia has a small number of area codes, which makes choosing straightforward. The right number helps local customers recognise you, and the national options help larger customer-facing teams.
| Number | Region or use |
|---|---|
| 02 | New South Wales and the ACT, including Sydney |
| 03 | Victoria and Tasmania, including Melbourne |
| 07 | Queensland, including Brisbane |
| 08 | Western Australia, South Australia and the Northern Territory |
| 04 | Mobile numbers |
| 13 and 1300 | National numbers used by businesses |
| 1800 | Freecall numbers, free for callers from most landlines |
Local numbers
A local area code such as 02 for Sydney tells customers you are nearby. It works well for trades, clinics, agents and service businesses.
Mobile numbers
A mobile number beginning with 04 feels personal and suits sales reps and consultants who want customers to reach them directly.
13, 1300 and 1800 numbers
These non-geographic numbers are common for customer service and larger businesses because they are not tied to one city. Availability depends on the provider, so check before you plan.
Choosing the right number
- List where most of your customers live.
- Decide whether a local or a national feel suits you.
- Check what your provider offers in Australia.
- Give each team member their own number if you want to track results.

Calling Australia from abroad
If your team is overseas but your customers are in Australia, a local number helps because people answer numbers that look familiar. Remember the time difference, and plan call windows so you reach people during their working day.
