You’re driving through the foothills of the Appalachian Mountains, maybe coming in from Johnson City or over the gap from Virginia, and you see that sign: Welcome to Kingsport. It’s a place that feels sturdy. It’s the "Model City," after all, a town literally designed from the ground up to be the perfect balance of industry and greenery. But when you’re trying to mail a package, move into a new house, or just figure out where "Fairview" ends and "Colonial Heights" begins, you realize that the zip for Kingsport TN isn't just one single number.
Honestly, it’s a bit of a jigsaw puzzle.
Kingsport is split between two counties—Sullivan and Hawkins—and that complexity bleeds into the way the mail gets sorted. If you just type "Kingsport zip" into a search bar, you'll get a list. But a list doesn't tell you why your insurance rates might change when you move three blocks over, or why some people in the 37660 area feel a world away from the folks in 37663.
The Main Players: 37660, 37663, and 37664
If you live in Kingsport, there is a 90% chance you’re using one of these three codes.
37660 is the heart of the beast. It covers the downtown area and the historic neighborhoods. This is where you’ll find the iconic Church Circle and the sprawling Eastman Chemical Company plant. It’s the densest part of the city. Houses here range from grand, century-old estates on tree-lined streets to smaller, post-war bungalows that young families are currently snapping up and renovating.
Then you’ve got 37664. This is largely the eastern side of town. Think of the Indian Path Community Hospital area and the shopping corridors. It’s a mix of established suburban pockets and newer developments. If you’re looking for a mid-century ranch with a big backyard, you’re probably looking in 37664.
37663 is different. It’s the Colonial Heights area. If you ask someone from Colonial Heights where they live, they might not even say "Kingsport" first. They’ll say "Colonial Heights." It’s technically part of the city, but it has its own distinct vibe—lots of rolling hills, the Warrior’s Path State Park nearby, and a slightly more "rural-suburban" feel. It’s the zip for Kingsport TN that people choose when they want a little more breathing room but still want to be ten minutes from a Target.
The Ones Most People Forget
- 37665: This covers the Lynn Garden area. It’s often overlooked but has deep roots in the city’s industrial history.
- 37662: This is primarily for P.O. Boxes. If you’re doing business in town, you might see this on a letterhead.
- 37669: This reaches out toward Fall Branch and the more rural stretches of the county.
Why the Zip for Kingsport TN Actually Matters
It’s not just about the mailman finding your porch. In the Tri-Cities region, your zip code is a shorthand for your lifestyle.
Take the school systems. Kingsport City Schools are highly rated—the Dobyns-Bennett High School band is basically a local legend—but not every address with a Kingsport zip code is actually inside the city limits. This is a huge trap for people moving from out of state. You could have a 37660 address but technically be in the county, which means your kids might be slated for Sullivan County Schools instead of the city system.
It’s a headache. You’ve gotta check the tax maps, not just the zip code.
Then there's the "Kingsport smell." Locals know what I’m talking about. Depending on which way the wind blows and which zip code you’re standing in, you might get a whiff of the industrial side of the Model City. 37660 gets the brunt of it because of its proximity to the plants, whereas 37663 is usually far enough south and east to stay in the clear.
The Hawkins County Side of the Story
Most people think Kingsport is strictly a Sullivan County town. It’s not.
A chunk of the western side of the city sits in Hawkins County. This creates a weird situation where you might have a Kingsport mailing address but pay taxes to Rogersville (the Hawkins county seat) and use Hawkins County services. If you’re looking at property in the 37660 area, specifically heading toward Mount Carmel or Church Hill, you’ve got to be real careful about which side of the county line you’re on.
It affects everything from your car tags to who shows up if you call the fire department.
Actionable Steps for Navigating Kingsport Zips
If you are moving to the area or trying to verify an address, don't just trust a Google Map pin.
- Check the Sullivan County GIS or Hawkins County Property Assessor’s site. This is the only way to know for sure if a specific house is "City" or "County."
- Verify your school zone. If you’re eyeing a house in 37664 specifically for the city schools, call the Kingsport City Schools administrative office. The borders are jagged and confusing.
- Look at the sales tax. Some areas just outside the city limits have different tax rates. It might only be a fraction of a percent, but it adds up over a decade of grocery trips.
Basically, the zip for Kingsport TN is a starting point, but it's never the whole story. Whether you're settling into a historic home in 37660 or a quiet cul-de-sac in 37663, you're becoming part of a "planned" city that still manages to be full of surprises. Just make sure you know which county is sending you a tax bill before you sign the closing papers.
