You’re driving down Highland Drive, past the REI and the local bagel shops, and you think you know where you are. You're in Millcreek. Or maybe you're in Salt Lake City? Honestly, it depends on who you ask—and more importantly, it depends on which Millcreek Utah zip code is written on your mail.
Millcreek is a weird spot. It’s one of Utah’s newest cities, officially incorporating only back in 2016, but it’s also one of the oldest settled areas in the valley. Because of that "new city, old neighborhood" identity crisis, people constantly mess up the borders. If you’re looking for a house or trying to set up a business here, the zip code matters more than the city name on your GPS.
The Three Big Ones: 84106, 84109, and 84124
Most people assume a city has one zip code. Millcreek has several, and they don't care about city limits.
The 84106 zip code is the heart of the "Canyon Rim" and "Sugar House-adjacent" lifestyle. It’s the vibe everyone wants. You’ve got the old brick bungalows and the massive trees that have been there since the pioneers decided this was a good spot for a farm. But here's the kicker: half of 84106 is actually in Salt Lake City proper. If you live on the north side of 2700 South, you’re in the city. South of that? You’re in Millcreek. It’s a mess for taxes, but great for property values.
Then there’s 84109. This is the east bench. If you see a house with a view of the entire valley and a backyard that basically touches the Wasatch Mountains, you're likely in the 09. It runs along the I-215 belt route and includes the Olympus Cove area. It's steep. It's expensive. It’s also where the snow stays on the ground three weeks longer than anywhere else in the valley.
Finally, we have 84124. This is the southern chunk of the city. It’s a bit more mid-century modern, a bit more suburban, and it feels a world away from the hustle of downtown SLC, even though you can get to Temple Square in fifteen minutes.
Why the Millcreek Utah zip code is a branding nightmare
When Millcreek became a city, it didn't magically get its own post office. That’s why your mail might still say "Salt Lake City, UT 84106" even though you pay your property taxes to the Millcreek City Council.
It's confusing.

Businesses struggle with this constantly. A local shop on 3300 South might list their address as SLC because that's what the USPS database says, but they’re actually part of the Millcreek business license program. If you're searching for "Millcreek Utah zip code," you have to realize that the federal government (the Postal Service) and the local government (the City of Millcreek) aren't always talking to each other.
The 84117 and 84107 Overlap
It gets worse. Or better, depending on how much you like trivia.
Small slivers of 84117 (mostly associated with Holladay) and 84107 (mostly Murray) bleed into the official Millcreek city boundaries.
- 84117: Mostly the southeastern corner near Big Cottonwood Creek.
- 84107: The western edge near the TRAX lines and the industrial zones.
Why does this matter? Schools.
If you’re moving here specifically for the Granite School District, you need to check the map, not just the zip. A zip code tells the mailman where to go; it doesn't tell your kid which elementary school they’re zoned for. Skyline High and Olympus High are the big names here, and their boundaries are a jagged zig-zag that mocks the simplicity of a five-digit zip code.
Real Estate Reality Check
Let’s talk money. If you’re looking at a listing in 84109, you’re paying a premium for the "East Bench" prestige. Homes here regularly clear the $1 million mark, especially as you get closer to the mountain.
In contrast, 84106 offers more "starter" homes (if $600k can still be called a starter home in 2026). The lots are smaller, but you're walking distance to parks and coffee shops.

The 84124 area is the sweet spot. You get larger lots than the 06, but lower prices than the 09. It’s the "sensible" Millcreek.
The Demographic Shift
Millcreek isn't just for retirees anymore. It used to be. For decades, it was the place people went to fade away into quiet suburban bliss.
Not now.
Young professionals who got priced out of the 9th and 9th neighborhood in Salt Lake City are flocking to the 84106 and 84124 areas. They want the yard. They want the proximity to Millcreek Canyon. You can literally leave your office in Millcreek and be hiking the Pipeline Trail in ten minutes. That access is the primary reason the Millcreek Utah zip code data shows such a high median income compared to the rest of the county. People move here specifically because they have the money to prioritize the outdoors.
The Secret of the "Unincorporated" Days
Before 2016, this whole area was just a "township." It was the Wild West of Salt Lake County. Zoning was weird. Sidewalks were optional. This is why, if you walk through certain parts of the 84106 zip code, you’ll see a brand-new $2 million modern farmhouse sitting right next to a 1940s shack with a horse in the backyard.
That's the Millcreek charm. It’s inconsistent.
The zip codes reflect this history. They weren't designed for a unified city; they were designed for rural delivery routes that eventually got paved over. When you look up a Millcreek Utah zip code, you are looking at the fossilized remains of old farm boundaries.

Practical Steps for Residents and Newcomers
Stop relying on your phone's "auto-fill" for your address. It will lie to you.
If you are moving to the area or trying to identify a specific location, do these three things:
- Check the Millcreek City Interactive Map. Don't look at Google Maps; look at the municipal boundary map on the official city website. It’s the only way to know if you’re actually in the city limits or just in a Salt Lake City zip code that neighbors it.
- Verify the School District. If you have kids, go to the Granite School District's boundary seeker tool. Enter the specific house number. Do not assume that because your neighbor goes to one school, you will too. The lines are that tight.
- Confirm Your Property Taxes. If you’re buying, look at the tax ID. Millcreek has its own tax rate, which differs slightly from unincorporated Salt Lake County or SLC proper. Knowing your zip code isn't enough to calculate your monthly escrow payment accurately.
The Millcreek Utah zip code situation is a perfect example of how digital maps struggle with human history. Whether you’re in 84106, 84109, or 84124, you’re in one of the most desirable spots in the Intermountain West. Just make sure you know which "Millcreek" you’re actually buying into before you sign the papers.
The boundaries are messy, the history is long, and the views are worth every bit of the confusion.
Find your specific plot, check the city services, and enjoy the mountains. They’re the only thing in Millcreek that doesn't change when the zip code does.
Actionable Insight: For the most accurate data regarding utility providers (which vary wildly by zip code in this area), use the Salt Lake County Assessor's property search. Cross-reference the "Tax District" field with the city’s official boundary map to ensure you are receiving the correct municipal services.**
