I wish USA would take a stronger stance on mobile numbers being used for identity - either permanently assigning numbers to people which can't be reassigned or banning the use of phone numbers for identity verification entirely. Your life should not be identified by a sequence of numbers that are no longer yours if you don't pay your bill or somebody pretends to be you in a cell phone store. That said, Google has allowed me to use my Google Voice number for account verification for a very long time now. It probably helps that I added that number before I ported it over to Google Voice but it's nice not having accounts tied to phone bill.
