🇦🇺 Australia Phone Number Format
Australian numbers are 9 digits after the trunk 0 (10 digits in national format). Mobiles start with 04, while landlines use single-digit state area codes — 02 (NSW/ACT), 03 (VIC/TAS), 07 (QLD), 08 (SA/WA/NT) — and the 0 is dropped the moment you dial through +61.
Australian Numbers in All Four Standards
Here is how one Australia number is written in each of the four standards:
| Format | Example | Use for |
|---|---|---|
| E.164 | +61491570156 | Databases, SMS APIs (Twilio, WhatsApp), CRMs |
| International | +61 491 570 156 | Display to a global audience, business cards |
| National | 0491 570 156 | Domestic display inside Australia |
| RFC3966 | tel:+61-491-570-156 | Clickable tel: links on websites |
ACMA’s Plan: State Codes, 04 Mobiles and 13 Numbers
Australia compressed dozens of regional codes into just four giant geographic zones during the 1990s renumbering, which is why a single area code like 02 covers everything from Sydney to Canberra. The trade-off: the area code tells you the state, never the city.
The 13, 1300 and 1800 families are Australia’s inbound-service numbers — six or ten digits, priced for the caller at local or zero cost. They are routing aliases rather than real lines, which is why most cannot be reached from outside Australia at all. If a business only advertises a 13-number, overseas callers need its +61 geographic alternative.
For test data and documentation, ACMA reserves specific numbers including the mobile 0491 570 156 used throughout this page — structurally perfect, permanently unallocated, and accepted by libphonenumber-based validators.

Australian Numbering Essentials
- ACMA reserves 0491 570 156 and similar numbers for fictional use — they are safe example numbers.
- Australian mobiles are always 04 + 8 digits; in E.164 they become +614XXXXXXXX (11 characters with the +).
- 13 and 1300 “local rate” numbers are 6 or 10 digits and cannot be dialed from outside Australia.
- Landline area codes cover whole states, so an 02 number can be anywhere in NSW or the ACT.
Mistakes to Avoid with Australian Numbers
- Keeping the 0 after +61 — “+61 0491 570 156” will fail; the correct form is +61 491 570 156.
- Publishing only a 13/1300 number for an international audience — most are unreachable from abroad.
- Assuming the area code pins down a city — 02 spans all of New South Wales and the ACT.
- Storing mobiles without the leading 0 domestically (491 570 156) — ambiguous; normalise to E.164 +61491570156.
