On the third hand, it's still true that the large majority of them are in the U.S.Would you agree that 408-921 is a geographic number?No. It's a prefix, assigned to the at&t switch in west San Jose.I guarantee you that there are phones within that prefix within US/Calif/LATA-1 and also some well outside of that, probably not even in the same country.Who said anything about phones? Could you describe what "geographic numbers can be located to a switch" means to you?
I guarantee you that many, if not most at this point, of those numbers are no longer actually handled by that switch most of the time. I suspect that there are more SS7 exceptions than default within that particular prefix which is why I chose it. Owen
