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
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.

regulatory agency web sites,
provided by the state of New York

online: archives, chat room, etc.

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

It had a MAP of the area code split, a LIST OF TOWNS affected by the split, and excellent

since the 803/843 split is "old news," but BellSouth is to be commended for its
excellent work on that project.)
