I just found this site a few minutes ago:.
I've barely clicked around in it. But it could be useful for anyone who needs to see area code layouts.
I realize that area codes exceed boundaries any more. Regardless of what the area code(s) is/are on a person's phone, they could be anywhere in the world where there is wireline or wireless service available.
Nevertheless, some of you may find this Web site to be useful.
Apologies if this URL has already been posted on Telecom Digest. I don't remember seeing it, though.
