Skype numbers support this (in some countries), too. I live outside the US but have a US Skype number for this very purpose.
It's bad enough having banks rely on a phone system where most carriers are perfectly happy to let anyone who knows your Address, DOB and Mother's Maiden name to port your phone number to a new SIM.
It probably requires less effort (and certainly less risk of discovery) to take over a Skype, Google Voice or other VOIP/SMS service.
