NAME
       areacode - examine table of US telephone area codes
SYNOPSIS
       areacode pattern1 [pattern2...]
DESCRIPTION
       Areacode  is  a Bourne shell script which searches a table of telephone
       area codes.  The search pattern pattern may be an area  code  or  text.
       If  a  matching pattern contains tabs or spaces, it should be contained
       within double quotes.
EXAMPLES
       To find the area codes for New York, simply type:
              areacode "New York"
       whereas to find the region associated with area code 802, type:
              areacode 802

AUTHOR
       Areacode is based on a script by Alexander Dupuy
       <dupuy@hudson.cs.columbia.edu>, posted in 1989 and 1990.

       The current area code information is at
       http://www.bennetyee.org/ucsd-pages/area.html;  
       the website is maintained by Bennet Yee
       <bsy+areacodes@bennetyee.org>.

       John Rupley <rupley@u.arizona.edu> assembled the areacode
       script in its current form.

       The data for the script are from January, 2004.
       Clearly, the data have changed since then, as have the rules
       for area codes -- portability!

Bennet Yee's webpage has other useful information in the header and
footer bracketing the data:

                    ------------------------------


The cities listed with each area code are the major cities for that area
code; this originated as the city in which the /switch/ computer for
that area code is located, but is no longer the case. The cities listed
are /not/ intended to be exhaustive.

This list is updated /only/ when an Internet user informs me of a
(pending) change. There are no special data sources from which this is
generated -- just the cooperation of the Net. I do /not/ have anything
to do with phone companies etc; I do research in computer security, and
this is just a random service
<http://smac.ucsd.edu/cgi-bin/http_webster?service> for/of/by the
Internet community.

<http://www.nanpa.com/> data. There's also a listing at geocities
