12 digit numbers cell phones
All US phone numbers are either 7 or 10 digit numbers. All 10 digit number calls must be proceeded by dialing 1 (this shows on the caller id system). It is a 12 digit number and it is not proceeded by a 1 (even international numbers are proceeded by the 1).Planning for 12digit subscriber numbers would begin decades out, and probably be quite unpopular with users; 12digits being longer than most people can comfortably remember at the moment. Implementation would depend on whether your idea is to be implemented in a single region or nationwide. 12 digit numbers cell phones
Sep 16, 2012 I've stopped answering calls from the number, and usually I'd write this sort of thing off as a prank, or just an annoying, but the 12digit number with a national calling code I can't identify, and the caller's persistence has got me quite annoyed.
