Telephone area code/Talk

Removed "The United States is stuck with 3 digit area codes, because it was one of the first countries to have area codes and is so stuck with old technology." because it didn't sound NPOV and IMO was not correct.

I haven't heard of the plan that was described for adding a 9; if this exists, I believe it is at most still a proposal.

Somewhere this article should explain (better) why NPAs fill up.

Personally, I think we should think about unallocating unused numbers, usused being any number which is not published for dial-in. For example, many companies have a block of numbers in a roll-over group, of which they only use one. - Justfred
