So, you’re looking for the zip code for Erie Colorado. Most people just want a five-digit number and they’re done. But if you're moving here, mailing a package to a new build in Colliers Hill, or trying to figure out why your car insurance rates just spiked after moving three blocks, there’s actually a lot more to the story than just hitting "search."
Erie is weird. I mean that in the best way possible, but geographically, it's a bit of a headache.
The primary zip code for Erie, Colorado is 80516.
That’s the big one. If you live in the historic downtown area, or many of the sprawling new developments like Vista Ridge, that’s what you’re putting on your envelopes. But here is where it gets tricky: Erie isn't just in one county. It straddles the line between Weld County and Boulder County. Because of that split, and the way the United States Postal Service (USPS) handles routing, you might occasionally see references to other nearby codes like 80026 (Lafayette) or 80503 (Longmont) creeping toward the town borders. However, for 99% of residents, 80516 is the golden ticket.
Why the Erie Colorado zip code is more than just a number
Zip codes were originally just about mail sorting. Simple, right? Not anymore. Today, that 80516 designation dictates your sales tax, your school district options, and even how much you pay for home insurance.
In Erie, your "place" on the map is a moving target.
Because the town is growing at a breakneck pace—we're talking about a population that has more than doubled since 2010—the infrastructure is constantly playing catch-up. I've seen situations where a developer breaks ground on a new subdivision and the GPS hasn't even registered the road names yet, let alone confirmed which post office is going to handle the heavy lifting.
If you are looking at a map of the 80516 zip code, you’ll notice it’s shaped like a jagged puzzle piece. It covers the heart of the town but also stretches out into the more rural, agricultural sections of Weld County. This creates a strange mix of suburban "Stepford" vibes and old-school Colorado farm life all sharing the same mailing prefix.
The Weld vs. Boulder County Split
This is the part that trips up new residents every single time. About 60% of Erie sits in Weld County, while the remaining 40% is in Boulder County.
Why does this matter for your zip code?
Well, the 80516 zip code is serviced primarily by the Erie Post Office located at 1250 Telleen Ave. However, the tax you pay at the local Safeway or when you register your car is determined by your county, not your zip code. You can have two people living in 80516, but one pays Boulder County property taxes (higher) and the other pays Weld County property taxes (generally lower).
It’s a quirk of Colorado geography.
Does Erie have a 80026 zip code?
Technically, no. 80026 belongs to Lafayette. But because the borders between Erie and Lafayette are basically invisible—just a street sign on Baseline Road or Highway 287—a lot of people get confused.
If you’re on the far western edge of town, near the Nine Mile Corner development, you might feel like you’re in Lafayette. Your neighbors across the street might even have a Lafayette address. But if you’re within the Erie town limits, you are 80516.
Using the wrong zip code in this area can actually cause significant delivery delays. The mail for 80516 goes through a different sorting facility than the mail for 80026. If you put "Lafayette, CO 80516," the automated sorters might have a minor existential crisis before a human finally intervenes to fix it.
The logistics of living in 80516
Let's talk about the post office itself. The Erie Post Office isn't huge. In fact, for a town that's pushing 30,000 people, it feels a bit nostalgic. If you’re moving into one of the new high-density neighborhoods, you likely won’t have a mailbox at the end of your driveway.
You’ll have a CBU.
A "Cluster Box Unit." Those big metal banks of mailboxes at the end of the block.
It’s a point of contention for some. People miss the "Mayberry" feel of a mailman walking up to the porch. But in the 80516 zip code, efficiency is the name of the game. With hundreds of new residents arriving every month, the USPS has standardized these cluster boxes to keep the mail moving without having to hire an army of new carriers.
Shipping and Freight issues in Erie
One thing I hear all the time from people living in the newer parts of 80516—think areas out toward the Erie Air Park or the northern edges near Highway 52—is that FedEx and UPS sometimes struggle.
The zip code is accurate, but the geofencing in their private databases isn't.
If you’re ordering something expensive, always double-check that the "City" is listed as Erie. Occasionally, an automated system will try to "correct" your address to Longmont or Broomfield because the 80516 boundaries are so expansive. Don't let it. Stick to your guns. Erie is its own entity.
Real Estate and the 80516 "Premium"
Is there a zip code premium in Erie? Honestly, yeah.

Real estate agents will tell you that the 80516 zip code has become a "brand." It signals a specific lifestyle: the view of the Front Range, the proximity to the Erie Community Center (which is world-class, by the way), and access to the St. Vrain Valley or Boulder Valley school districts.
When you see "80516" on a Zillow listing, it usually commands a higher price point than some of the more rural zip codes further east in Weld County. It’s the "sweet spot" between the urban density of Denver and the mountainous isolation of the foothills.
A quick look at the numbers
To give you an idea of the scale of this zip code area:
- Land Area: Roughly 20-25 square miles depending on recent annexations.
- Households: Over 10,000 and growing.
- Median Income: Significantly higher than the state average, often hovering in the $120k+ range.
These aren't just dry stats. They explain why the 80516 zip code is getting so much attention from commercial developers. Everyone wants a piece of that demographic. It’s why we’re seeing new shopping centers pop up at the intersection of Highway 7 and I-25, even if those areas technically have different zip codes (like 80023).
Common mistakes to avoid with the Erie zip code
- The "Lafayette" Mistake: Don't assume that because your kids go to a Boulder Valley school, you have a Boulder or Lafayette zip code. Check your closing documents.
- Sales Tax Confusion: If you buy a car, make sure the dealership uses your specific address to calculate tax. If they just see "80516" and assume Weld County, but you actually live in the Boulder County portion of Erie, you might end up with a bill for the difference later.
- Emergency Services: This is the big one. If you call 911, the dispatchers generally use your location data, but in a town with a split zip code and split county, knowing exactly where you sit relative to the county line helps the Erie Police or Mountain View Fire Department find you faster.
The future of 80516
Will Erie get a second zip code?
It’s possible. The USPS doesn't like to change things unless they have to, but with the "Erie Highlands" and other northern developments expanding toward Longmont, the volume of mail might eventually force a split. For now, though, 80516 is the king of the hill.
It’s a weird, sprawling, beautiful part of Colorado. From the old coal mining tunnels that still sit deep underground near the downtown area to the multi-million dollar hangars at the Air Park, 80516 covers a lot of ground.
Actionable steps for 80516 residents
If you’ve just moved in or you’re planning a move, do these three things immediately to make sure your "zip code life" is handled:
- Verify your county: Go to the Erie Town website and use their interactive map to see if you are in Weld or Boulder County. This affects your voting, your taxes, and your car registration.
- Update your "My USPS" account: This is the best way to track packages in a high-growth area where Google Maps might not have your house listed yet.
- Check your school district: Just because you are in the Erie zip code doesn't mean your kids go to Erie High School. Some parts of 80516 are zoned for schools in neighboring towns.
Basically, 80516 is more than a mailing address. It's a ticket into one of the fastest-growing, most vibrant communities in the Rockies. Just don't be surprised if your GPS takes a year or two to figure out exactly where your driveway is.
That’s just the price of living on the "New Frontier" of the Front Range. If you're mailing a letter, just write 80516, make sure your stamps are centered, and trust the folks at the Telleen Avenue office to get it where it needs to go. They’ve seen it all.
