How to Write a Phone Number With Country Code: Australian and International Phone Number Format

To write a phone number with the country code, put a plus sign, the country code, then the number without its first 0. An Australian mobile 0412 345 678 becomes +61 412 345 678. This guide shows the international phone number format for Australia and other countries.

Updated 19 October 2026

International phone number format: + country code, then the number without its first 0, with spaces between groups. For Australia that is +61. A Sydney landline 02 9283 9292 becomes +61 2 9283 9292.

How to Write Your Phone Number With the Country Code

Type your Australian mobile number or landline number. The tool writes it in international format, the way people overseas need it.

International Phone Number Format: 3 Rules

An international telephone number has 3 parts: a plus sign, the country code and the national number. The ITU standard E.123 says the + “should precede the country code in the international number” (ITU-T E.123).

  1. Start with +. The plus sign stands for the exit code, also called the international prefix or international dialling code, so it works from any country. From Australia the exit code is 0011.
  2. Add the country code. Australia is 61, the UK is 44 and the USA is 1. See our list of country codes.
  3. Add the number without its first 0. Keep the area code, and use spaces between groups of digits. Do not put the 0 in brackets.

An international number has at most 15 digits, country code included (ITU-T E.164).

Australian Phone Number Format and Area Codes

An Australian number in international format is +61, then the number without its first 0. The Australian Government Style Manual gives these examples (Style Manual):

  • Mobile number: 0491 570 159 becomes +61 491 570 159. Write the 9 digits in 3 groups of 3.
  • Landline: 02 5550 4321 becomes +61 2 5550 4321. Keep the area code without its 0.

08 Central and West Region: Western Australia, South Australia, the Northern Territory and parts of western New South Wales +61 8 XXXX XXXX

Area codes from the Telecommunications Numbering Plan 2025 (ACMA).

Phone Number Format for Other Countries

Most countries follow the same rule: drop the first 0 and put the country code in front. These mobile examples show the number as people write it there, with the country code, and the digits you dial from Australia.

When the Country Code Does Not Replace a 0

The country code replaces the first 0 in most countries. Some countries work differently:

  • No 0 to drop. Portugal, the Czech Republic, Denmark, Malta and Mexico have no trunk prefix. Write all the digits after the country code.
  • Drop more than a 0. Hungary drops 06, and Belarus drops 8 0, before the area code.
  • Shared codes. The USA, Canada and many Caribbean countries share +1. The 3 digit area code comes straight after the 1.

Enter a Phone Number With Country Code on a Mobile or a Form

  • On a mobile phone: touch and hold the 0 key until + appears, then type the country code and the number (Apple iPhone guide).
  • In your contacts: save numbers with + and the country code. They then work when you are overseas too.
  • On a web form: pick the country, then type the number without its first 0. If the form has one box, type + and the country code first.

Common Mistakes in International Phone Number Format

  • Keeping the 0: +61 0412 345 678 is wrong. Write +61 412 345 678.
  • Writing +61 (0)412: E.123 says brackets “should not be used in an international number”.
  • Writing 0011 or 00 in place of +: those prefixes work only from some countries. The + works from everywhere.
  • Using dashes or dots: E.123 separates digit groups with spaces.

Frequently Asked Questions

How do I write an Australian phone number in international format?

Write +61, then the number without its first 0. A mobile 0412 345 678 becomes +61 412 345 678, and a landline 02 9283 9292 becomes +61 2 9283 9292.

Is +44 the same as 07?

No. +44 is the country code for the UK. UK mobiles start with 07 inside the UK, so a UK mobile in international format starts +44 7.

Is the US country code 011 or 1?

The US country code is 1. 011 is the prefix that people in the USA dial to call out of the country. From Australia dial 0011 1, then the 10 digit number.

Does the country code replace the 0?

In most countries, yes: drop the first 0 and write the country code in front. Some countries, such as Portugal and Denmark, have no 0 to drop, and Hungary drops 06.

How many digits can an international phone number have?

At most 15 digits, including the country code, under the ITU standard E.164.

Should I put (0) in an international phone number?

No. The ITU standard E.123 says brackets should not be used in an international number. Write +61 2 9283 9292, not +61 (0)2 9283 9292.
