The ability to properly format phone numbers becomes vital for daily communication because it enables effective contact with international parties. You need to learn the correct Australian mobile number format when you communicate with Australian people or provide your mobile number to others. So, how to write Australian mobile number with area code? This blog will explain Australian mobile number structure and area codes significance while showing you a step-by-step method for correct number formatting.
Understanding Australian Mobile Numbers
The Australian Communications and Media Authority (ACMA) regulates the telecommunications system that consists of Australian mobile numbers throughout the country. The phone numbers maintain their uniqueness through a standardized format for maintaining both clarity and consistency. Australian mobile numbers contain ten digits where the area code represents one part of the sequence.
Key Components of an Australian Mobile Number
- Country Code: Australia’s country code is +61. The country code +61 functions when making international phone calls from outside Australia.
- Area Code: Mobile phone numbers in Australia begin with the area code 04. Mobile numbers possess their own unique 04 area code which separates them from landline numbers that use different area codes.

- Subscriber Number: Mobile user identification runs across the final eight digits of the number sequence.
Why Area Codes Matter?
Area codes help both identify the phone service type between mobile and landline while also revealing the location region of a phone number. Mobile phone numbers in Australia use the 04 area code regardless of location since it remains constant throughout the country. The standard mobile area code enables quick identification of mobile numbers compared to landlines because they use state-specific area codes.
How to Write Australian Mobile Number With Area Code?
Now that we’ve covered the basics, let’s dive into how to write Australian mobile number with area code in different scenarios:
# 1. Writing for Domestic Use (Within Australia)
When writing an Australian mobile number for use within the country, follow this format:
Format: 04XX XXX XXX
04: The mobile area code.
XX XXX XXX: The 8-digit subscriber number, typically written in groups of 3 or 4 digits for readability.
# 2. Writing for International Use
Australian mobile numbers shared with international contacts need the addition of the country code +61 before the mobile area code and subscriber number. Here’s the correct format:
Format: +61 4XX XXX XXX
Example: +61 412 345 678
Key points to remember:
- The initial zero of the Australian area code requires replacement with the international code +61.
- The country code must follow the mobile number without any gaps or special characters between them.
# 3. Writing for Online Forms or Databases
Many online forms and databases require phone numbers to be entered in a specific format. For Australian mobile numbers, the standard format is:
Format: 614XX XXX XXX
Example: 61412345678
In this case:
- The leading 0 is dropped.
- The country code 61 is added directly before the mobile number.
- Spaces are omitted for consistency.
Common Mistakes to Avoid
When writing an Australian mobile number with area code, people often make these mistakes:
- Incorrect Country Code: The use of any country code different from +61 represents a mistake when writing Australian phone numbers.

- Omitting the Area Code: The area code 04 for mobile numbers should always be included.
- Incorrect Formatting: Unnecessary spaces as well as hyphens and parentheses added to mobile numbers can cause confusion for automated systems.
Tips for Writing Australian Mobile Numbers
- Use Spaces for Readability: Human readers should see mobile numbers broken into sections using spaces for better readability (0412 345 678).
- Include the Country Code for International Use: You must include +61 as the first part of an Australian mobile number when providing it to international contacts.
- Double-Check the Number: Check the number twice to make sure it matches the proper format before you distribute it to others.
