And, of course, the "local calling" part of LocalCallingGuide.com is 
extremely useful;  your alternative is to search ILEC tariffs 
exhaustively yourself (have fun with that), or purchase expensive 
commercial databases from the likes of CCMI or Telcordia that digest 
this information.  I don't know where the LCG guy gets _that_ 
information, but it is extremely useful.

Everything related to rate center identification, NPA-NXX to locale 
resolution, NPA-NXX to LATA mapping, rate center to LATA mapping, 
NPA-NXX to LEC resolution, NPA-NXX-Y to LEC resolution, etc. is just 
peanuts, though: the information is free and available.  I just linked 
to it.
