[Bob Larkin <blarkin@xxxxxx>]

Here is the distribution of digits for all current area codes in the NANP

Digit   1st     2nd     3rd
0            0       72        41
1            0       71        30
2          45       20        29
3          34       24        29
4          32       24        33
5          35       24        28
6          38       28        30
7          43       27        29
8          42       19        30
9          40         0        30

There are a total of 309 area codes. Beware of the following codes, as they can
genereate large bills:
   242 Bahamas
   246 Barbados
   264 Anguilla
   268 Antigua and Barbuda
   649 Turks & Caicos Islands
   868 Trinidad and Tobago
   869 St. Kitts & Nevis

These area codes, and several others, go to "foreign" areas, but a dialed as a
1+ call. for the definitive answers, go to
www.nanpa.com.   "This site provides information about the North American
Numbering Plan (NANP) and its administration. The NANP   is the numbering plan
for the Public Switched Telephone Network in the United States and its
territories, Canada,  Bermuda, and many Caribbean nations, including Anguilla,
Antigua & Barbuda, Bahamas, Barbados, British Virgin Islands, Cayman Islands,
Dominica, Dominican Republic, Grenada, Jamaica, Montserrat, St. Kitts and
Nevis, St. Lucia, St. Vincent and the Grenadines, Trinidad and Tobago, and
Turks & Caicos. "
