The phone number is probably the best worldwide ~1 to ~1 identifier. I say keep it, for now at least.

- Symbiote 5y agoI don't know about most, but a lot of people have more than one phone number. I have a personal mobile number, a personal mobile number from the country I used to live in, and two work numbers. If I take a longer trip somewhere, I might have another mobile number for a few weeks. I don't have one now, but landline numbers are generally shared between a whole household.
