You're looking for the Dacula Georgia zip code, but here is the thing: it isn’t just a single five-digit number. Most people type 30019 into their GPS and call it a day. That's the main one. It covers the city proper and a massive chunk of unincorporated Gwinnett County. But if you’re actually living here, or trying to mail something to a specific new development near the edges of Auburn or Hamilton Mill, things get a little blurry.
Dacula is weird. In a good way.
It’s this pocket of Georgia that managed to stay "country" way longer than its neighbors like Lawrenceville or Buford. You’ve got horse farms sitting five minutes away from a brand-new Publix. It’s growing fast. Like, really fast. Because of that, the Dacula Georgia zip code boundaries feel like they’re bursting at the seams. People move here for the schools—specifically the Dacula and Mill Creek clusters—but they often get confused about where Dacula ends and the next town begins.
The 30019 Breakdown and Why It Matters
The primary Dacula Georgia zip code is 30019. This is the heavy lifter. If you live in the city limits, you’re 30019. If you live in one of the sprawling subdivisions off Harbins Road, you’re 30019.
But here is where it gets tricky for delivery drivers and new residents. Dacula shares borders with Lawrenceville (30043/30045), Hoschton (30548), and Auburn (30011). Sometimes you’ll find a house with a Dacula mailing address that is actually physically located in the city of Auburn. Or you’ll be in a neighborhood that feels like Dacula, but your taxes go to Lawrenceville.
Why should you care?
Insurance rates. School districts. Local taxes.
If you are looking at real estate, don't just trust the "Dacula" label on Zillow. Check the specific parcel data. Some homes in the Dacula Georgia zip code area are zoned for Archer High School, while others are Dacula High or even Mill Creek. In Gwinnett County, your zip code doesn't always dictate your school zone, which is a common trap for parents.
What’s actually inside 30019?
It’s a massive area. You have the historic downtown—which is tiny, charming, and has that classic train-track vibe—and then you have the suburban sprawl.
- Little Mulberry Park: This is the crown jewel. It’s over 890 acres. If you’re in 30019, you’re likely minutes from one of its entrances.
- The Rabbit Hill Park complex: Great for soccer families.
- The Retail Hub: Most of the shopping is clustered around Highway 29 and Winder Highway.
Real Talk on Growth and Traffic
Dacula used to be a place where you'd see more cows than cars. Not anymore. Honestly, the traffic on Highway 316 is a nightmare during rush hour. If you are moving to the Dacula Georgia zip code and planning to commute to Atlanta, prepare yourself. You aren't just driving; you're battling.
The Georgia Department of Transportation (GDOT) has been working on the 316 interchanges for years. They are trying to turn it into a full freeway by removing the at-grade intersections. This is a big deal for property values in 30019. Once those traffic lights at Harbins Road and Winder Highway are fully gone and replaced with flyovers, the commute might actually become "tolerable" rather than "soul-crushing."
But growth has a price.
The quiet two-lane roads like Fence Road or Hamilton Mill Road are now packed with SUVs. New developments are popping up on every available acre of former farmland. It’s a classic suburban evolution. If you want the "old Dacula" feel, you have to head further east toward the Barrow County line, but even there, the 30011 zip code is starting to look a lot like 30019.
The School District Confusion
Let’s address the elephant in the room. Most people search for the Dacula Georgia zip code because they want their kids in Gwinnett County Public Schools (GCPS).
GCPS is huge.
Within the 30019 area, you primarily have the Dacula Cluster. Dacula High School is a pillar of the community. It has a deep history. But, as the area expanded, the Mill Creek Cluster was formed to take the pressure off. Now, parts of Dacula are zoned for Mill Creek (located in Hoschton/Braselton area) and parts are zoned for the newer Seckinger High School—the one with the massive focus on Artificial Intelligence.
If you are buying a house specifically for a school, verify the map. Do not assume 30019 equals Dacula High. Use the GCPS "School Look-up" tool. It’s the only way to be 100% sure before you sign a mortgage.
Is Dacula actually "In the Mountains"?
No. But it feels like the start of them.
You’re in the foothills. The terrain in the 30019 zip code is much hillier than what you’ll find in southern Gwinnett or down toward Decatur. This means two things: beautiful views and expensive driveway repairs. If you’re moving here from a flat state, the steepness of some of these suburban streets will be a shock during the one week a year Georgia gets "winter weather."
The Cost of Living Reality
Is Dacula cheap? No. Is it cheaper than North Fulton or Buckhead? Absolutely.
In 2026, the median home price in the Dacula Georgia zip code has climbed significantly. You’re looking at a range. You can find older 1970s ranch houses on an acre of land for a decent price, or you can drop nearly a million on a custom-built home in a gated community with a golf course nearby.

Property taxes in Gwinnett are no joke. However, the services you get—massive parks, well-maintained libraries, and top-tier police and fire response—are generally considered worth it by the locals.
Hidden Gems in 30019
If you're just passing through or newly moved, you'll probably stick to the big chains. Chick-fil-A, Publix, Kroger. The usual.
But you've gotta look closer.
There are local spots that define the 30019 lifestyle. Del Rio Mexican Grill is a staple. It’s where everyone goes after a Friday night football game. Then there’s the Dacula Briar Patch—an old-school gift shop and tea room vibe that feels like stepping back thirty years.
And don't sleep on the Ezzard Family Farm. It's one of those places that reminds you of what Dacula used to be before the subdivisions took over. They do organic produce and educational tours. It's a slice of the "real" Georgia right in the middle of a booming zip code.
Logistics: Mail, Shipping, and Confusion
Every year, people complain that their packages are delayed or that their "Dacula" address shows up as "Auburn" on Google Maps.
Here is the deal: The post office uses "preferred city names." For 30019, that is Dacula. However, because the zip code covers parts of the county that are technically closer to the Auburn post office, sometimes the software gets wonky. If you’re ordering something expensive, always double-check that your zip code is 30019 and not 30011 if you are right on that border.
Detailed Area Stats (No Tables Needed)
The population of 30019 is roughly 60,000 people now. That's a massive jump from twenty years ago. The median household income sits well above the Georgia average, hovering around $95,000 to $105,000 depending on which census tract you’re looking at. Most residents own their homes—about 85%. It’s not a big rental market, though more build-to-rent communities are starting to sneak in near the main thoroughfares.
Why 30019 Still Wins
Despite the traffic and the rapid construction, the Dacula Georgia zip code is still one of the best places to live in the metro Atlanta periphery.
Why?
Balance.
You can work a high-tech job in Alpharetta or downtown Atlanta and come home to a place where you can actually see the stars. You have access to Lake Lanier (about 25 minutes away) and the North Georgia mountains (about 45 minutes away). You get the suburban amenities without the claustrophobia of the inner suburbs.
Actionable Steps for New Residents
- Check the School Map: Go to the Gwinnett County Public Schools website and use their "Find My School" tool with your specific address.
- Verify Your City Taxes: Determine if your property is within the "City of Dacula" limits or "Unincorporated Gwinnett." This changes your trash pickup and property tax rate.
- Get a Peach Pass: If you plan on using I-85 or 316 to get to work, just do it. You’ll regret it if you don’t.
- Visit Little Mulberry Park: Enter through the Fence Road entrance for the best views and the least crowded trails.
- Join Local Groups: Find the "Dacula Community" groups on social media. It’s the fastest way to find out why there’s a helicopter circling or which plumber everyone trusts.
The Dacula Georgia zip code of 30019 is more than just a mailing address. It’s a specific lifestyle choice that trades a longer commute for better schools and a bit more breathing room. Just make sure you know exactly which side of the line your house falls on before you move in.
Next Steps:
If you are moving to the area, start by visiting the Gwinnett County Tax Assessor’s website to look up the historical tax data for any property in the 30019 zip code. This will give you the most accurate picture of your true monthly housing costs beyond just the mortgage payment. Once settled, register your vehicle at the Gwinnett Tag Office in Lawrenceville, as the 30019 area does not have its own dedicated tag branch.
