To call a UK number from a US cell phone, you dial the plus sign (+), then the country code 44, then the local number without its leading zero. This sequence is the exact method for connecting to any UK phone from your mobile device, and it relies on understanding international calling codes and dialing formats.
How to call a UK number from a US cell phone
Follow these steps in order to place a call from your US cell phone to a UK number:
- Press and hold the 0 key on your cell phone keypad until a plus sign (+) appears. You can typically get the '+' symbol on most cell phones by holding down the '0' key. This is the international access code that replaces the exit code used on landlines.
- Dial 44, the country code for the United Kingdom.
- Dial the UK phone number, but omit the leading zero that is used for domestic calls within the UK. For example, if the UK number is 020 1234 5678, you dial 20 1234 5678 after the +44.
The complete dialing sequence is: +44 [area code without the leading 0] [local number].
Account for time zone differences between the US and UK (GMT/BST) to avoid calling at inconvenient hours. Be aware of cultural norms and business hours in the UK when scheduling calls.
Dialing a UK landline number
For a UK landline number, the dialing format is +44 followed by the area code (without its leading 0) and then the local number. A complete UK landline number, including the area code, typically consists of 10 digits after the country code. For a London number such as 020 1234 5678, you would dial +44 20 1234 5678. The area code (20 for London) is included without its leading zero, and the local number follows directly.
Dialing a UK mobile number
UK mobile numbers begin with a leading zero when dialed domestically, such as 07712 345678. To call this number from a US cell phone, remove the leading zero and dial +44 7712 345678. The mobile prefix (7712 in this example) becomes part of the local number after the country code.
Understanding the costs to call the UK
International calling rates may apply when you call a UK number from a US cell phone. Your carrier may charge per minute or require an international calling plan. Consider using an international calling card to add credit to your account for making international calls at a lower rate. If you make frequent international calls, you may want to consider switching to a mobile service provider that offers favorable international calling rates and plans. Check your specific plan or contact your provider to confirm the rates before dialing.
