For obvious reasons, SSN as a unique ID is out. Given the (relative) portability of phone numbers, these might be a good option. Alternatively, allowing users to employ their email address as the unique ID would be awesome! I'd pay an annual fee to USPS if senders could just write my email on an envelope and it would get to me (bonus points for selective digitization).
I think this is one of the beauties of Google Voice service: It's indirect addressing for my phone number. If USPS took some initiative, they could really invigorate their service and bring it into the technical age.
They already have this, of course. You can send USPS a change-of-address form and they'll send mail addressed to you at your old address to your new address. https://moversguide.usps.com/icoa/icoa-main-flow.do?executio...
If you used an old email address, you wouldn't get e-bills either.
I have some rubber stamps made with
ADDRESSEE GONE AWAY
RETURN TO SENDER
and that seems to cut down the amount of repeated post. You can dump all the post for one person in a big envelope and dump that in a post box once a month.Yes, of course.
Also mail forwarding's worked pretty well for me. Just fill the info online or drop the card in the mail.
