As someone moved several times in my life I could support (potentially several) personal uuid with global post routing service. Having declaring new postal address to all essential and random places one by one where I was mandated to give out to receive something I couldn't miss (authorities, banks, essential service providers, all else) is a common nuisance in an otherwise difficult period of life. Having a trustful[*] service (preferably post services itself, trusted parcel services) that translates a postal uuid to a current address each time a postal mail is supposed to be sent, current living address is righfully needed, would be a great advance (some countries have a postal address change service locally, some partially, that does similar).

[*] trustful, yes, that is a hard nut to crack! Who can be trusted with physical address and for what purpose, but in some sense it may be better for its controlled nature rather than the wild west of postal address world that we live in.
