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 , 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 . John Rupley 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 for/of/by the Internet community. See also the listing by state/country and the NANPA data. There's also a listing at geocities and areacode-info.com Area Code Region Timezone Offset (from UTC ) Description [data....] See NIST 's Boulder labs ' explanation of GMT versus UTC .
