Calling United Kingdom from Australia

Dial 0011 (the Australia exit code), then 44 (United Kingdom’s country code), then the local number with its leading 0 removed. So +44 20 7946 0123 is dialled as 0011 44 20 7946 0123. From a mobile you can dial +44 directly instead of 0011.
Dialling United Kingdom from Australia: start with 0011, the exit code for Australia, then 44 for United Kingdom, then the local number with its leading 0 dropped. The diagram shows those three blocks and the leading-zero rule that catches most people out.
The + shortcut on a mobile replaces the exit code entirely, which is why it works on any SIM in any country.

Step by step

Dialing United Kingdom from Australia

Four steps, and the third one is where almost every failed call goes wrong.

  1. 1

    Dial 0011: the exit code for Australia

    0011 tells the Australia network that the call is leaving the country. On a mobile you can press and hold 0 to type a + instead, which works from any country and any SIM; it is the more reliable option when you travel.
  2. 2

    Dial 44: the country code for United Kingdom

    44 is United Kingdom's country calling code. It never changes and is the same no matter where you are calling from.
  3. 3

    Drop the leading 0 from the local number

    Numbers written for domestic use in United Kingdom begin with 0. That digit is a national trunk prefix and is not part of the number. Remove it: +44 20 7946 0123 is dialled as 20 7946 0123 after the country code.
  4. 4

    Check the local time before you dial

    United Kingdom is on GMT/BST (UTC+0/+1) and Australia is on AEST/AEDT (UTC+10/+11). Work out the overlap before calling; the most common cause of an unanswered international business call is simply the hour.

Ofcom reserves 020 7946 0XXX and 07700 900XXX for drama and documentation, so these examples cannot ring a real person.

One thing about United Kingdom

The leading 0 in 020 or 07911 is a domestic trunk prefix. Drop it when dialling from abroad: +44 20…, never +44 020…

Frequently asked questions

How do I call the United Kingdom from Australia?
Dial 0011, then 44, then the local number with its leading 0 removed. For example, +44 20 7946 0123 is dialled as 0011 44 20 7946 0123.
What is the country code for United Kingdom?
+44. From Australia you reach it by dialling 0011 first, or by dialling + directly from a mobile.
Do I include the 0 when calling United Kingdom?
No. The leading 0 is only used inside United Kingdom. Including it from abroad is the most common reason the call fails to connect.
How do I call a United Kingdom mobile from Australia?
Exactly the same way as a landline: 0011 + 44 + the mobile number without its leading 0. A United Kingdom mobile in international format looks like +44 7700 900123.
What is the time difference between Australia and United Kingdom?
Australia is on AEST/AEDT (UTC+10/+11) and United Kingdom is on GMT/BST (UTC+0/+1). Because several of these zones observe daylight saving on different dates, check the current offset rather than assuming a fixed gap.
Is it cheaper to call United Kingdom over the internet?
Usually, yes. Carrier international rates are typically far above VoIP per-minute rates, and calling from an owned local number also means the person you are calling sees a number they can ring back.
