Am looking for a site where one can enter the AC and NNX and find out

One site to look at is telcodata.us There is also a lookup on dandy.net, but don't have that handy. Just checked it out if you go to
formatting link
and type in the search box NXX it will tell you where that is e.g. NXX = 508-775 will get you a result of Hyannis, Massachusetts. NXX = 206-354 will show Seattle, Washington NXX = 207-549 will show North Whitefield, Maine.
Oh, and BTW NNX is likely not what you're looking for. NXX would be the format of area codes and central office codes. NXX means N= any number between 2 and 9 and X= any number i.e. 0 - 9 (including 1 and
0.)
