Formula
From the US: 011 (or +) → 61 → Australian number without the leading 0.
| Type | Domestic in Australia | Save as (portable) | Dial from US |
|---|---|---|---|

| Mobile | 04XX XXX XXX | +61 4XX XXX XXX | 011 61 4XX XXX XXX |
X characters are placeholders, not a private callable number. Save +61 in contacts; use 011 only for all-digit US access.

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.
