USPS needs to implement a form of indirect addressing. The basic premise: Assign recipients a unique ID. The physical address is then a single indirect lookup (ie. from a database, which can be altered by the recipient ad nauseum). 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.
