Each country in the world is assigned
a three digit number. Some countries have more than one three digit number, and
you can find out what those international routing codes are at the
area codes by continent page.
For purposes of demonstration, we'll
use America. Every long distance number in America is preceded by a 1.
(i.e. 1 + area code + 7 digit number). America's international three digit
dialing code is actually 001. But when you call from within the US, you
don't have to use 001.
Calling from Continental Europe and England:
Europe operates on a standard set of numbering, and any time you call,
you are going to be using 01 as the country code for America. You may have a
Calling Card which has slightly different
instructions. If that's the case, listen to the instructions, and do what they
tell you to do. It could be 001 or just 1.
Calling from China:
It kind of depends on where you are in China, but China also has the
standard 3 digit country code numbering system. They also use three digits
as the International calling code. So make sure that you are entering 0-0-1 as
the country code for calling America from China. My advice is, if you can speak
a bit of Chinese, ask for the IP or IC
Calling Cards. (Phoenetically "wo-ah yow
my IP"
- Good luck!) If you don't speak Chinese, get a
calling card before you go.
Other:
Most countries in the world will follow one of these two standards (01
or 001) for making calls from abroad to America.
One of the easiest ways to avoid having difficulties when you
want to call America from abroad (when you travel especially) is to get a
calling card in advance. There are some very good
international calling card searches
highlighted in this site.
