How to call the United Kingdom (international dialing)

  • Do not dial a leading ‘0 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 mislabeled:

  • 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 mislabeled 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’). Do not include the leading ‘0’ when calling from outside the United Kingdom, Jersey, Guernsey, and the Isle of Man.

When calling a mobile phone user, dial to the country where the mobile phone is registered, regardless of where the person is roaming.

… to a VoIP phone

Use the same call sequence.

VoIP phone numbers are typically in area codes ’05’ and ’08’. Do not include the leading ‘0’ 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, dial to the country where the VoIP phone is registered, regardless of where the person is roaming.

… to a satellite phone

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

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

… sending a fax

Use the same call sequence.
