I'm aware of portability. This doesn't create ownership, it simply seeks to alleviate the most common pain point around the fact that numbers aren't owned. It's not the same thing as ownership such as regards a domain name. Telcos can allocate numbers as they please, much as ISPs or web hosts can allocate IP addresses as they please to your services but this doesn't make you the owner of them. Fortunately, nobody uses IP addresses in their email addresses (though it is allowed).
