I mean, I just had the local library mail me a postcard so I could get a library card. Post office delivered it no problem and that's enough proof of residency for a lot of things.

I don't need an ID with a to turn on the gas and electric. Or, I haven't anywhere I've been.

I don't think it'd be hard to get an ID anywhere I can pick the mail, to be honest. I don't recall needing a document like a lease to get my last drivers license.

But then, I'm not squatting, and given that I try to keep a reasonable credit record and avoid court, I'm not disposed to start squatting.
