Kingsport, TN

ZIP code 37665 is a PO Box ZIP code serving Kingsport, Tennessee, rather than a distinct residential area, so it has no clear physical boundary for assigning landmarks. Major attractions in the broader Kingsport area include Bays Mountain Park and Planetarium, the Netherland Inn, Allandale Mansion, and the Kingsport Carousel; these should not be assumed to lie within 37665 itself.
