South Burlington is weird. Most cities have a clear center, a downtown, and a handful of post office codes that separate the suburbs from the shops. But if you’re looking for a South Burlington zip code, you’re basically looking for one thing: 05403. That’s it. It’s the solitary identifier for a city that’s constantly trying to prove it isn’t just a "suburb of Burlington."
It’s actually the second-largest city in Vermont now. Think about that for a second. It has more people than Rutland or Montpelier, yet it shares its mail identity almost entirely with a single string of numbers. People get tripped up because South Burlington wraps around the actual city of Burlington like a horseshoe. You can be driving down Shelburne Road, pass a car dealership, and cross the city line three times without even realizing it.
The Identity Crisis of 05403
When you write 05403 on an envelope, you’re hitting a massive geographic footprint. We’re talking about everything from the high-end lakefront properties on Orchard Shore to the busy commercial sprawl of Williston Road. Honestly, the 05403 zip code is a bit of a chameleon. It covers the Burlington International Airport (BTV)—which, despite the name, is fully located in South Burlington—and the University Mall.
If you live here, you’ve probably had to explain to a confused delivery driver that you aren’t in Burlington proper. "No, I’m near the park-and-ride," you say. Or "I’m over by the new City Center." This is where the confusion peaks. For decades, South Burlington didn't have a "middle." It was just a collection of developments. Now, with the development of Market Street and the new library, the South Burlington zip code finally has a heartbeat.
But here is the kicker: some people in South Burlington actually have a Burlington zip code (05401) depending on exactly where the mail carrier's route cuts off near the University of Vermont. It's a mess. ZIP codes were never designed to respect municipal boundaries; they were designed for the efficiency of the U.S. Postal Service. In 1963, when the system was launched, South Burlington was mostly farmland and small neighborhoods. They didn't think they'd need a complex grid.
Why the Real Estate Market Loves 05403
If you're looking at Zillow, 05403 is the "Goldilocks" zone. Burlington is too expensive and the houses are often a century old with drafty windows and lead paint. Williston is too far out. South Burlington? It’s just right.
Property taxes here are a major talking point at every city council meeting. People pay a premium to be in this zip code because of the schools. The South Burlington School District consistently ranks as one of the best in the state. Rick Marcotte Central and Orchard School are huge draws. Families move across state lines specifically to get their kids into the 05403 system.
It’s not just about the schools, though. It’s the connectivity.
- You’ve got the Red Rocks Park for hiking.
- Access to the bike path that can take you all the way to the Colchester Causeway.
- The proximity to UVM Medical Center.
The real estate inventory in 05403 varies wildly. You have 1950s ranch homes in the Mayfair neighborhood and then you have multi-million dollar contemporary builds over by the Vermont National Country Club. It’s a diverse mix that you don't really see in the more monolithic suburbs.

The Great Border Confusion: 05403 vs. 05401
Let's get technical for a minute. The USPS doesn't care about your property taxes. They care about the truck route.
Because South Burlington and Burlington are so intertwined, there are pockets near the Spear Street corridor where the lines blur. Sometimes, your physical address says South Burlington, but your mail says Burlington 05401. This happens most often near the UVM campus and the hospital. If you’re a renter, this is a nightmare for setting up your utilities.
Most people don't realize that South Burlington actually used to be part of Burlington. Back in the 1800s, it was the "Town of Burlington" while the city was the "City of Burlington." They split because the farmers in the town didn't want to pay for the expensive infrastructure the city dwellers wanted. Fast forward to today, and the South Burlington zip code is the one seeing the most aggressive urban development in the state.
Navigating the Logistics of the Area
If you are moving to the area or just visiting, 05403 is home to the major transit hubs. The airport is the big one. If you’re flying into Vermont, you are landing in South Burlington.
Parking is another story. Unlike Burlington, where you’re constantly fighting for a spot or feeding a meter on Church Street, 05403 is largely built for cars. Huge lots. Wide roads. It’s convenient, sure, but the city is trying to move away from that. They want more walkability. That’s why the "City Center" project is such a big deal. They are trying to turn 05403 from a zip code into a destination.
What You Need to Know Before Buying or Moving
Don't just look at the number. 05403 is massive.
If you are looking for a house, check the school district boundaries carefully. Even within the 05403 zip code, where your house sits determines which of the three elementary schools your kids will attend.
Also, consider the flight path. Being the home of BTV and the Vermont Air National Guard means the F-35s are a reality of life here. Some people love the sound of "freedom," others find it incredibly disruptive. If you're looking at property in the northern part of the zip code, go there during a scheduled flight time. You'll thank me later.
Traffic on Shelburne Road (Route 7) is the other "feature" of 05403. It's the busiest road in Vermont. If your daily commute involves crossing from the south end of 05403 to the north end during rush hour, you’re going to spend a lot of time looking at brake lights.
Final Practical Takeaways for South Burlington
Stop worrying about whether your address says Burlington or South Burlington on your Amazon packages. As long as the 05403 is there, it’ll get to your porch.
- Verify the Municipality: Always check the tax maps if you're buying. Some properties on the border are confusingly zoned.
- School Choice: Understand that 05403 doesn't guarantee a specific elementary school; it depends on the neighborhood zone.
- Noise Mitigation: Check the airport's noise contour maps if you are sensitive to sound.
- Community Services: South Burlington has its own police, fire, and recreation departments. Don't call Burlington City Hall for a South Burlington problem.
The South Burlington zip code is more than just 05403. It's a growing, shifting identity for a city that is finally coming into its own. It’s the place where the convenience of the suburbs meets the ambition of a rising urban center. Whether you're here for the schools, the lake views, or just a quick commute to the hospital, 05403 is the anchor of Chittenden County.
Go to the South Burlington City Hall website to look up specific parcel IDs if you're ever in doubt about where a property actually sits. You can also use the Vermont Center for Geographic Information (VCGI) maps to see the exact parcel boundaries, which is way more accurate than a Google Maps pin. If you're moving here, get a resident pass for the parks early—Red Rocks is a gem but parking fills up fast in the summer.
