Description |
Validates *usable* US telephone numbers (possibly Canadian and Caribbean Islands as well?) Numbers cannot beginning with zero, one, (any number)11, or 555. It will allow either a hyphen, space or period as a separator.
Technically (and contrary to popular belief) most 555- numbers ARE valid numbers [see http://www.nanpa.com/nas/public/form555MasterReport.do?method=display555MasterReport ] but they are unlikely to be used by normal folks. Therefore, excluding them with this regex is useful to prevent bogus/fraudulent telephone numbers in forms.
FYI, the fictitious 555- numbers used in the movies and TV are only in the range of 555-0100 through 555-0199. Not very many, huh?
