Our ISP is exanding into other areas. Where can I find a list of what
numbers certain cities can dial locally? We want to get the best location
and phone number for the buck.
Thanks in advance,

i don't see that this is nanog material, unless we want to use it as a
springboard to begin complaining about a certain incumbent carrier...
however, the answers are easy:
*your local phone book should have pages in the front which should
list local calling areas, usually with a table of exchanges.
*call your local operator by dialing zero, and ask
them if, with your calling plan, you can call NXX-1 from NXX-2
toll-free. if s/he says s/he can't tell you that information, ask to
talk to their supervisor, because, as the entity billing you for such
calls, they should be able to tell you what their billing structure
is. (this is the most reliable method.)
if anyone knows of a centralized listing, i'd love to see it. this is
something that i deal with everyday, and it can be messy. generally
we get a table of "this NXX can be dialed toll free from these NXXs"
from whomever is providing our virtual NXXs. however, those lists
have proved incorrect in the past, and we INSIST that our phone staff
tell our customer to check their access number using the above
methods.

Not that this is of much use to most of you but for Ohio it is published on
the PUCO web page at http://www.puc.state.oh.us/pucogis/easmaps/EASMAP.HTM
Very useful for figuring out where to put terminal servers.
You might try your own state Public Utility Commission - at least in Ohio the
local calling area is a regulated function.

Look at the LERG (local exchange routing guide), available from
www.trainfo.com, 800$/single issue (monthly snapshot). If there are any
cheaper ways to get the LERG, I'd love to hear about them.
LERG has each NXX's 'rate center'. Calls within one rate center are
local. (I am not sure if it is mandated by FCC or individual PUCs)
There are some cases where calls between different NXXs in different rate
centers are considered local, but that varies between LECs, and I don't
think LERG covers that.
