Formula

From the US: 011 (or +) → 61 → Australian number without the leading 0.

X characters are placeholders, not a private callable number. Save +61 in contacts; use 011 only for all-digit US access.

Dial it step by step

  1. 1

    Exit the US network. On a mobile or modern contact book, start with +. On a US landline, PBX, or digit-only service, dial 011.

  2. 2

    Add the Australia country calling code: 61.

  3. 3

    Add the NSN after removing the leading domestic trunk 0. Retain the remaining area or mobile prefix.

Portable contact format: + 61 + NSN

Digits-only call from US: 011 + 61 + NSN

Mobile and landline rules

  • Mobile: domestic 04 becomes +61 4.
  • Sydney and its region: domestic 02 becomes +61 2.
  • Remove only the leading trunk 0; retain the area or mobile prefix that follows.

See the Australia calling-code reference and the international dialing format guide.

FAQ

What is the Australia country code from the US?

61. Dial 011 or +, then 61 and the Australian number without its leading domestic 0.

Do I dial 011 or +?

Use + on a mobile or saved contact when supported. Use 011 on a US landline or digit-only path. After that, use the destination country code and national significant number.

Why drop the zero?

The leading 0 is a domestic trunk prefix, not part of the NSN after country code 61.

How do I dial an Australian mobile from the US?

Drop the 0 from 04XX XXX XXX, then dial 011 61 4XX XXX XXX or +61 4XX XXX XXX.

How do I dial a Sydney landline from the US?

Drop the 0 from 02 XXXX XXXX, then dial 011 61 2 XXXX XXXX or +61 2 XXXX XXXX.
