Houlton is weirdly important. If you’re looking up the Houlton Maine zip code, you probably just need to mail a package or fill out a mortgage application, but there’s a massive amount of logistics packed into those five little digits: 04730. Most people don't realize that this single zip code covers an area larger than some entire counties in Southern New England. It’s the gateway. It's where the I-95 literally ends and hands you over to Canada.
It’s 04730. That’s the number.
But honestly, if you’re moving here or doing business in Aroostook County, the zip code is just the start of the conversation. Houlton is the shire town of the "County," and it carries a heavy load for the surrounding rural patches.
Why the 04730 Zip Code is More Than Just a Number
When you type 04730 into a GPS, you aren't just getting a small town center. You’re getting a massive geographic footprint that includes Houlton, but also touches parts of Ludlow, New Limerick, and Hammond. It’s the hub.
The United States Postal Service (USPS) runs the main office right on Court Street. It’s a classic, brick-and-mortar operation that feels like the 1950s in the best way possible. Because Houlton is a border town, this zip code is a hotbed for international shipping and customs brokers. If you've ever bought something from a Canadian seller that magically arrived via USPS, there’s a decent chance it passed through the 04730 sorting system.
The Geographic Reach
The area is vast. We are talking about nearly 150 square miles of territory. While the population density is low—roughly 6,000 people in the town proper—the zip code services a much wider net of farmers, foresters, and off-grid dwellers who rely on that Houlton postmark for everything from Amazon deliveries to vital agricultural supplies.
It's cold here. Like, "don't leave your liquids in the car" cold. That matters for the mail. During the winter months, the 04730 delivery routes are some of the most grueling in the Northeast. Mail carriers aren't just dodging traffic; they're navigating seasonal roads that sometimes vanish under four feet of drift.

Living and Working in Houlton Maine Zip Code 04730
If you're looking at real estate in the Houlton Maine zip code, you'll notice something immediately. The prices look like a typo from twenty years ago. You can still find a Victorian mansion with original woodwork for the price of a parking spot in Boston. But there’s a trade-off.
The economy is gritty. It's based on potatoes, timber, and the border.
- Agriculture is the backbone. The soil here is Caribou loam—the "black gold" of the north.
- Border Patrol and Customs are major employers. Being the terminus of I-95 makes Houlton a strategic point for national security.
- Small business culture is alive on Market Square. It’s one of the few places where the downtown hasn't been completely gutted by big-box stores, though the North Road has its fair share of Walmarts and chain restaurants.
Market Square and the 04730 Vibe
Market Square is the heart of 04730. It's a circular downtown area with raised sidewalks and historic architecture that feels remarkably European. Honestly, it’s one of the most beautiful downtowns in Maine, even if a few storefronts are perpetually waiting for their next big idea.
If you visit, you have to go to the Temple Cinema. It’s one of the oldest continuously operating independent movie theaters in the state. They still do affordable popcorn. They still care about the community. It’s that kind of place.
Connectivity and Logistics in the 04730 Area
A huge misconception about the Houlton Maine zip code is that it’s "in the middle of nowhere." Geographically? Sure. Logistically? Not even close.

The Border Factor
You can't talk about 04730 without talking about Canada. The relationship is porous. Or at least, it was before the world got complicated.
