I'm bummed by this, because I live in a weird corner case and wanted to see where we fall on this map. Our legal address is in West Fairlee, VT 05083, but our mail is routed through the post office in Fairlee, 05045, and must be addressed to that town and ZIP code or it doesn't arrive. Just to make life more interesting, Another part of town delivers out of Thetford and does use 05083. All this in a town of about 600 people.

As a result of that, and address verification services, our de facto address is our mailing address. Except for the handful of times a year, usually pertaining to state taxes directly or indirectly, when we have to ask which address is actually needed/intended. Even in those cases, it's the source of confusion since the two differ by the addition of "West" to the town name and two digits in the ZIP code.
