Is it feasible for a regular American to keep their physical address private?

I've always wished the USPS would provide this as a service. I register my name and/or any number of virtual address aliases. Then, I privately keep the USPS up to date with a physical address for each alias.

You can take it even further and authorize requests for verification. E.g., I can let my car insurance company see my zip code, or even just get a yes/no that I live in a specific zip code.

Something to consider: Don't register to vote. Might seem counterintuitive but your address is publicly available if you do. Too bad since voting seems important, but not more important than personal privacy if you are in a similar situation.

Certainly. Put the home in a trust with an address at a law office. As long as you never tell anyone that is your address, and as long as you never have any of your billing or payments, or anything under your name connected to that address, it is certainly possible. Of course, everything would have to be paid for/billed to etc. a shell essentially at the law office

I always found it interesting that you cannot have a domain name without publishing your address and phone number, or paying for an extra service.
