Knoxville, TN

ZIP code 37950 is a PO Box–only code for Knoxville, Tennessee, rather than a geographically bounded neighborhood. Consequently, no major landmark can be reliably identified as lying within the ZIP itself. Prominent Knoxville landmarks include Market Square, the Tennessee Theatre, and World’s Fair Park, home of the Sunsphere, but these are city landmarks rather than confirmed features of ZIP 37950.
