How do you call an American cell phone from a foreign country such as Japan? -

Basically, how does one contact a American cell phone with a phone from Japan, do you have to call the phone number with area code as well as a country code and if so what is the country code to call United States, etc.

1 is the country code for USA and Canada then the area code then the number So an example would be 1-111-111-1111

It s the same for landline numbers. You do the international country code (001) and then the phone number (including area code, obviously).
