Making a call to Australia? Understanding their phone number format can ensure your international connection goes smoothly. Here's a breakdown:
Structure: Use eight digits – a four-digit exchange code followed by a four-digit local number.
Area Codes: A single digit identifies the general region (e.g., 2 for Sydney, 3 for Melbourne). This digit is prefixed to the eight-digit number for a total of nine digits nationally.
Calling Within Australia: To dial a landline outside your area code, add the national trunk prefix (0) before the area code.
International Calls: For japan phone number international calls, use the international dialing prefix (+) followed by the country code (61 for Australia) and the nine-digit number (dropping the leading zero of the area code).
Mobile Phones:

Structure: Ten digits total, consisting of the national trunk prefix (0), a mobile indicator (4 or 5), and eight digits.
Mobile Indicators: 04 denotes a Telstra or Optus number historically, while 04x can be used by any carrier due to mobile number portability.
Writing for Australians: Within Australia, mobile numbers are commonly written as 04XX XXX XXX.
Writing Internationally: When presenting mobile numbers to an international audience, use the format +61 4XX
Always double-check the number before dialing to avoid international call charges to unintended recipients.
Consider using an international calling app that can handle dialing the correct format for you.
