How to write a Australia number in E.164
- Remove spaces, dashes, dots and brackets so only digits are left.
- If the number starts with the trunk prefix 0, remove it. It is only used when dialling inside Australia.
- Put +61 in front. The result has 9 digits after the country code for a mobile.
So 0412 345 678 becomes +61412345678. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Australia allocates separate number ranges to mobiles and landlines, so a numbering-plan check reads the line type straight from the digits, for free. That type describes the range the number came from. It doesn’t prove the number is connected today.

Common questions
- What is the country code for Australia?
- The country calling code for Australia is +61. It is shared with 2 other countries and territories, so the number after it decides which one a number belongs to. When you call Australia from abroad, dial your international prefix (or +) followed by 61 and the number without its leading 0.
- How many digits is a Australia phone number?
- A Australia mobile number has 9 digits after the country code +61, the same as a landline. Written for dialling inside Australia, a number gains the trunk prefix 0 in front.
- How do I write a Australia number in international format?
- Start with +61, drop the leading 0, then add the rest of the number. The mobile number 0412 345 678 becomes +61 412 345 678, or +61412345678 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a Australia number is a mobile?
- Usually, yes. Australia numbers come from ranges allocated separately to mobiles and landlines, so a numbering-plan check reads the line type from the digits. It tells you what the range is for, not whether the number is in service.
