How to call a phone number in London from the United States

Updated on July 6, 2007

The number you have for London might be presented in a number of different ways:

+44 (0)20 5555 5555 (this has the UK country code)

020 5555 5555 (this assumes you're calling from within the UK)

5555 5555 (very unlikely, because it doesn't include the area code)

In each case you'll need the country code (44 for UK), and the area code, minus the leading zero (20 in the case of the example above).

To call any international number from the US, start with 011 first (from a landline phone) or hold down the 0 button until it turns into a + (from a cellphone).

011 44 20 5555 5555 (from a regular landline phone)

+44 20 5555 5555 (from your cellphone)

      Elaine, on my phone (a Motorola) you have to hold * for the +, not 0. Maybe yours is the same way.

      Holding down the 0 did not change into a +. What am I doing wrong? I want to call a cell # and must use the +44. This is very frustrating

      Matthew - maybe your cell phone is not enabled by your carrier to send international text messages.

      If you think this is confusing, Italy uses the same system with the 0 before the number, and it was like the UK so that you'd have to eliminate the 0 when calling from overseas. Then they changed it so that now you do have to put the 0 in. Unless of course, you're calling a cell number in which case you don't use 0. Oh fer cryin' out loud!!!:)

      It takes time to adjust, now I don't that much mostly e-mails and chat with overseas friends. This is a good one for those who want to call UK, same priniciple for other countries also.

      Gawd, calling between countries over here is such a PITA. Though, at least here they write it +420, so you don't have to wonder what the friggin 0 means! The first time I ever called Europe from the US (to AMS) it took me 5 tries to figure it out. I could have used this hub then, lol. :)
