Area Code Resource - Possibly off topic

[williams.jeff]

We're rolling out a bunch of offices and I'm trying to find a resource that list NPAs and has some details about them. Basically, I need to know about the local area dial plan- what area codes exist in the local area, are all numbers 7 or 10 digit, etc.

Anybody have a good online resource?

TIA,

Jeff

The North American Numbering Plan Administration website at http://www.nanpa.com has at least part of what you're asking for.

Look at the QTEL products.

NOT cheap though.

I use NANP and also the attached calling guide which is a little easier to use.
