Other Telecom-Related Sites
- Neustar NANPA — the administrators of the
area code system [NANPA was formerly administered by Lockheed-Martin, and before that by Bellcore.]
- The TelMex web page about new area codes in México is no longer available.
(NOTE: Every number in México changed, and the new
numbers are mandatory effective 2002-02-16.) All numbers in Mexico are now of the form
+52 nn xxxx-xxxx (Mexico City = 55, Guadalajara = 33, Monterrey = 81) or of the form
+52 nnn xxx-xxxx (all other locations).
- One of the most-requested items is a listing of prefixes within an area code.
NANPA now has a set of zipped tab-delimited text files listing
assigned
and available prefixes.
The files are divided by groupings of states, and by available versus utilized;
once unzipped, the files can be imported into Excel or other programs.
- Telcordia (formerly Bellcore)
Traffic Routing Administration
(T.R.A.), official information on prefixes and other routing issues. T.R.A. used to
issue a free monthly update called the NNAG, listing prefixes scheduled to be activated
or deleted in the near future. However, free distribution of the NNAG was discontinued.
- Listing of state and provincial
regulatory agency web sites,
provided by the state of New York
- TELECOM Digest
online: archives, chat room, etc.

(NOTE: this site now offers lookups of single prefixes,
with a limit of 5 lookups per 48-hour period.)

dialaround, calling card, and inbound toll-free service; highly recommended

charges for using various "dial-around" long-distance carriers, including surcharges and

- BellSouth had an excellent page about the
South Carolina coastal area code split (803/843) — an exemplary site.
It had a MAP of the area code split, a LIST OF TOWNS affected by the split, and excellent
overall detail on the whole split process. (The pages are no longer on the web,
since the 803/843 split is "old news," but BellSouth is to be commended for its
excellent work on that project.)
