Tennessee is home to 626 ZIP codes spanning 95 counties and 476 cities, reflecting the state's wide geographic and demographic diversity. ZIP codes in Tennessee fall within two broad numerical ranges — 370xx through 379xx for the central and eastern parts of the state, and 380xx through 385xx for western Tennessee including the Memphis metro area. Shelby County, anchored by Memphis, leads the state with 56 ZIP codes, while Nashville's Davidson County follows with 39. From the mountain communities of East Tennessee to the river cities of the west, the state's postal system covers a rich and varied landscape.
Tennessee ZIP codes span two distinct prefix ranges: the 370–379 series covers Middle and East Tennessee, including major cities like Nashville and Knoxville, while the 380–385 series covers West Tennessee, including Memphis and the surrounding Delta region. This east-west split in prefixes reflects the USPS sectional center facility organization, which historically divided the state's mail processing across geographically logical hubs. Together, the 16 active prefixes provide complete coverage across Tennessee's diverse regions, from the Appalachian highlands in the east to the Mississippi River lowlands in the west.
Shelby County leads all Tennessee counties with 56 ZIP codes, a reflection of its status as the state's most populous county and home to Memphis, a major metropolitan and logistics hub with dense urban, suburban, and commercial postal needs.
