Concerning the NANP, I have found two excellent sites which are the most accurate and up-to-date I could find. Here are a list of links you could find interesting: <H2><A HREF="http://www.lincmad.com">LincMad: Telephone Area Codes & Splits</A></H2> <A HREF="http://www.lincmad.com/cities.html">List of area codes and cities:</A> This includes all area codes in the NANP, to find a city or area code rapidly, the best thing to do would be to load the page and then use your browsers' ability to "Find in Frame" found in the "Edit" toolbar, enter your city or area code and click "Find Next", you should have your result promptly (note: some browsers do not have this function). <br> <A HREF="http://www.lincmad.com/locator.html">Locator Guide:</A> Same thing than previously, except that it is listed by area code instead of states/provinces/countries. <br> <A HREF="http://www.lincmad.com/splitmap.html">NANP map:</A> Excellent map showing all current and future area codes in the U.S. and Canada.<br><br> To see all the other links available on that page, follow the enlarged link named LincMad.<br> <br> <h2><A HREF="http://www.areacode-info.com">L.I.N.C.S.</A></H2> This page is also quite interesting and complete, but is a lot heavier in graphics and java applets, so if you have a slow connection, it may not be recommanded.<br> <A HREF="http://www.areacode-info.com/maps/default.htm">Maps of area code splits:</A> This page gives a listing of area code split maps since 1995.<br> <A HREF="http://www.areacode-info.com/telcos.htm">NANP Service providers:</A> A list of companies offering telephone services in the NANP.<br><br> Once again, to see the other links available on this page, click on the enlarged link named LINCS.
