codes and Internet country domain identifiers. It also lists the
telex code and international dialing code, wherever it is available.
It will also list major Internet "Public" E-Mail addresses.
This list is designed to show the corresponding codes for Fax and
voice messages, telex country codes, telex answerbacks and Internet
