How to call the United Kingdom (country code +44)

Calling to the United Kingdom

  • A leading ‘0’ is not included in the international call sequence – it is only used in the United Kingdom for domestic long distance calls and domestic calls to a mobile phone.
  • A leading '+' in the phone number means 'dial your country's exit code'.
  • Calling from a mobile phone: dial from on the country where you're currently located.
  • Calling from a VoIP or satellite phone: dial from on the country where the phone is registered.

The U.K.’s country code may be mis-labelled:

  • Country code 0044 (exit code of ’00’ used in many European, Asian, and African nations followed by the United Kingdom’s country code of ’44’).
  • Country code 01144 (exit code of ‘011’ used in the United States and Canada followed by the United Kingdom’s country code of ’44’).

When calling to a mis-labelled country code, remove the exit code from the call sequence and replace it with the exit code of the country the call is dialed from.

… to a mobile (cellular) phone

Use the same call sequence.

Mobile phone numbers are represented by area codes ’07’ (except for ‘070’). The leading ‘0’ is not included when calling from outside the United Kingdom, Jersey, Guernsey, and the Isle of Man.

When calling a mobile phone user, call to the country where the mobile phone is registered, regardless of where the person being called is currently roaming.

… to a VoIP phone

Use the same call sequence.

VoIP phone numbers are typically in area codes ’05’ and ’08’. The leading ‘0’ is not included when calling from outside the United Kingdom. Not all ’05’ and ’08’ phone numbers are VoIP phone numbers – they are shared with other services in these area codes.

When calling a VoIP phone user, call to the country where the VoIP phone is registered, regardless of where the person being called is currently roaming.

… to a satellite phone

The United Kingdom does not have a country-speicifc satellite phone system.

Most satellite phones operate on their own country code – calls to these satellite phones follow their own call sequence.

… sending a fax

Use the same call sequence.

Calling within the United Kingdom (domestic dialing)
