":I think it had better be ""North American"", not ""U.S."", because the area codes are used for Canada and a few other countries as well as the U.S. (see North American Numbering Plan).  I'll try to get started on this today.  I've never really moved or merged articles before, so I hope you'll let me know if I mess something up (and maybe show me how to fix it?)  BTW, how does one merge an article while preserving the edit history?  Thanks, again.   23:30, 2005 May 19 (UTC)
