Dialing sequence, step by step

  1. 1

    Start with + on a mobile, or 011 when the United States network requires an all-digit access prefix.

  2. 2

    Add 61, the country calling code for Australia.

  3. 3

    Add the destination national significant number. Remove the leading domestic 0 before adding +61.

Use +61 from a mobile or saved contact. From a US line that requires digits, replace + with 011 and remove Australia's domestic trunk 0.

Mobile and landline examples

X means a subscriber digit placeholder, so these patterns explain the transformation without publishing a private callable number. Save the + format; use the access-prefix format only for a call that starts in United States.

How the international format is built

Portable contact format

+ 61 + national significant number

The + represents international access. It is display notation, not one of the E.164 digits.

Digits-only call from United States

011 + 61 + national significant number

The first part routes out of the origin network and must not be stored as part of the destination.

E.164 limits the full international number to 15 digits and excludes international and national prefixes. See the E.164 and international-format guide for the reusable structure and regional exceptions.

Common mistakes for this route

  • Dialling 011 61 followed by the Australian domestic 0.
  • Forgetting that the Australian area or mobile prefix remains after only the leading trunk 0 is removed.
