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.
• The AreaCode-Info.Com site (contains history, future projections, and thorough detail about area code splits and other topics, plus links to many other sites; maintained by John Cropper and Eric Morson)
• World Telephone Numbering Guide (Dave Leibold) [link updated 2002-02-11]
• Telecom Paper, general telecom news, including a section on numbering issues
• Prefix lookup from TheDirectory.ORG (NOTE: this site now offers lookups of single prefixes, with a limit of 5 lookups per 48-hour period.)
• ABTolls: info on phone rates for one-plus, dialaround, calling card, and inbound toll-free service; highly recommended
• "10-10" phone rates: information about charges for using various "dial-around" long-distance carriers, including surcharges and monthly fees, for domestic and international calls.
• Other T&I Resources from the NTIA

• AreaCoder from Stevens Creek Software (software for PalmOS to update an address list, either automatically or interactively; can also "Hot Sync" with PC or Macintosh-based PIMs)

• Area Code Repair service from Professional Computer Consulting, Inc.
• The Phone Booth (focus on Canadian area codes and prefix assignments, also worldwide area code listings)
• 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.)
