The extensive list  by courtesy of the Guide       http://kropla.com/dialcode.htm

"Country Code   The country code should be used when dialing TO that particular country
FROM another country. In some cases you will also need to dial a city or area
code. When a country name appears in the table as a link, there will be
additional information regarding city or area codes. If you are aware of
more current city/area code information than that shown, or if you can add a
code, please send in a report.   IDD Prefix   The IDD prefix is the access code that you dial
to make a call FROM that country TO another country. This is followed by the country code         
for the country you are calling (see above). The IDD situation in many countries has
been changing regularly. If you are aware of more current information than
that shown here, please send in a report.  
Some countries have multiple IDDs, with each one used by a different long-
distance carrier.  Below is a table listing Country Codes and IDD (International Direct
Dialing) prefixes.
