[Talk-us] County Line Corrections

I know of some weird cases of borders and rivers, particularly along the Mississippi, where it has changed course.  There's a case near Wilson, Arkansas where the river has changed course, and a few square miles of land on the west side of the river belongs to Tennessee.  However, for obvious practical reasons, the post office that services that area is based in Arkansas - so the same zip code crosses state lines.

So to be accurate, one has to go to county/state/judicial records
individually if the higher res boundary data isn't made available
somewhere online already?
