Australia Phone Number Format: +61 Country Code Guide

Australia Phone Number Format: The Complete Guide

The Australia phone number format is used by over 26 million people across the continent. Whether you are calling Australia from abroad, filling out an international form, or setting up a virtual Australian business line, understanding the correct Australian phone number structure is essential.

A standard Australian phone number has 10 digits and always starts with a 0 when dialled domestically — for example, 02 XXXX XXXX for a Sydney landline or 04XX XXX XXX for mobile. When dialling internationally, you replace the leading 0 with the Australia country code +61 to get the full international format: +61 2 XXXX XXXX.

This guide covers every aspect of the Australian phone number format — from the +61 country code and number structure to mobile formats, area codes by state, real examples, sample numbers, and how to get an Australian virtual number from anywhere in the world.

Australia Country Code: +61 (Australian Calling Code)

The country code for Australia is +61. It is also written as 0061 when dialling from some countries using the exit code method. The +61 calling code covers the whole of Australia, including all states, territories, and external territories.

Many people search for the +61 area code or 61 area code — while +61 is technically the country code (not an area code), it functions as the international prefix for all Australian numbers. Area codes within Australia are the single-digit state codes (2, 3, 7, 8) that follow after you remove the leading 0.

Australia Country Code Key Facts

• Australia country code: +61 (also written as 0061)
• +61 area code: +61 is the country prefix; Australian area codes are single digits (02, 03, 07, 08) used as state codes
• +61 phone number always replaces the leading 0 of the domestic number
• Australia international phone code +61 was assigned by the ITU and covers every state and territory
• The 0061 country code is the same as +61 — used when your phone does not support the + symbol

Australian Phone Number Structure: How Many Digits?

A common question is: how many digits in an Australian phone number? The answer is 10 digits including the leading 0 — or 9 digits when the 0 is removed for international dialling. The structure depends on whether it is a landline or mobile:

In the Australian phone number format, a landline number is split into a 2-digit area code (the state code, beginning with 0) and an 8-digit local number. Mobile numbers do not use a geographic area code — they all begin with 04 followed by 8 digits.

For a comparison, the UK phone number format also uses a leading 0 and replaces it with the country code (+44) for international calls — the same rule applies to Australia with +61.

Australian Phone Number Examples and Samples

Below are real Australian phone number examples and Australian phone number samples showing the correct format for different states and number types. Each is shown as both domestic (with 0) and international (with +61) versions.

Australian Phone Number Sample for Testing

For a sample Australian phone number for testing, forms, or examples, Australia reserves the 0491 570 156–0491 570 159 mobile range and the XX 7010 XXXX landline range for fictional use. These will never be assigned to real subscribers, so they are safe to use in demos and documentation.

Australian Phone Number Length

The Australian phone number length is 10 digits domestically (including the leading 0). Internationally, an Australian phone number is 11 digits — the two-digit country code 61 plus the 9-digit number (after dropping the leading 0).

Australian Mobile Number Format: 04 Numbers

All Australian mobile numbers start with 04 when dialled domestically. This is the universal Australian mobile number format — if a number begins with 04, it is always a mobile. The australian mobile code is 04, where the 0 is the national trunk code and the 4 is the mobile indicator.

Internationally, an Australian mobile number in +61 format drops the leading 0 and adds +61, so 0491 570 156 becomes +61 491 570 156. This is the correct phone number in Australia format for international contacts and CRM systems.

How to Write an Australian Mobile Number with Area Code

A frequent question is how to write an Australian mobile number with the area code. The key point: Australian mobiles do not use a geographic area code like landlines. The "04" prefix is the mobile code — it replaces the state area code. So you write a mobile as 04XX XXX XXX domestically, or +61 4XX XXX XXX internationally. There is no separate city area code for mobiles.

Australian Area Codes by State (02, 03, 07, 08)

Australia uses four geographic area codes, each covering a group of states or territories. Every landline Australian phone number begins with one of these two-digit state codes. Here is the full breakdown:

People often search for specific codes like the 02 area code (New South Wales), the 08 area code (Western Australia, South Australia, Northern Territory), or the 0272 area code — note that 0272 is simply an 02 Sydney number where "72" are the first digits of the local number, not a separate area code. Australia only has four true area codes: 02, 03, 07, and 08.

How to Write an Australian Phone Number (Phone Number in Australia Format)

Writing an Australian phone number correctly depends on whether you are using it domestically or internationally. Here are the standard formats:

• Domestic landline: 02 7010 1234 (area code + 8-digit number, with leading 0)
• Domestic mobile: 0491 570 156 (04 prefix + 8 digits)
• International landline: +61 2 7010 1234 (drop 0, add +61)
• International mobile: +61 491 570 156 (drop 0, add +61)
• E.164 format: +61491570156 (no spaces, used in databases and APIs)

On international forms, business cards for global use, and CRM systems, always use the +61 phone number format. The E.164 format (+61 followed by the number with no spaces and no leading 0) is preferred for technical systems, SMS platforms, and VoIP services.
