Knoxville, TN

ZIP code 37939 is a PO Box–only postal designation for Knoxville, Tennessee, rather than a defined residential or commercial district. It has no separate neighborhood footprint, so no major physical landmarks can reliably be said to lie within its boundaries. Nearby Knoxville landmarks include Market Square, the Sunsphere, and the Knoxville Museum of Art, but those sites are associated with other downtown ZIP codes.
