If you are trying to mail a package to the shores of Sebago Lake or just moving into a new spot in Cumberland County, you've likely realized that the zip code for Standish Maine isn't just one single number. It’s actually two. Most people living in the main part of town use 04084, but if you’re further west, you’re looking at 04085.
It’s a bit of a quirk for a town with about 10,000 residents.
Honestly, Standish is one of those places where the geography is bigger than the population suggests. We’re talking over 80 square miles of land and water. Because the town is so spread out—stretching from the edge of Gorham all the way to the Saco River—the postal service split things up years ago.
The Primary Zip Code: 04084
For the vast majority of residents and businesses, 04084 is the one. This covers Standish Corner, Sebago Lake Village, and the areas surrounding Saint Joseph's College. If you’re heading to the Hannaford on Ossipee Trail or grabbing a bite at the Outpost Bar and Grill, you’re firmly in 04084 territory.
The main post office is located right at 111 Ossipee Trail East. It’s a busy little hub.
One thing you've gotta watch out for is that 04084 also encompasses Frye Island during the summer months. Frye Island is technically its own municipality now, but for mailing purposes, it still hitches a ride on the Standish zip code. If you’re sending something to a cottage on the island, don’t be surprised if the tracking says it arrived in Standish first.
Why the 04084 Boundary Matters
Living in this zone means you're part of the School Administrative District 6 (SAD 6). It’s a huge district. You’ve got kids from Standish, Buxton, Hollis, and Limington all mixing together.
The real estate in 04084 is pretty varied. You’ll see everything from $1.8 million lakefront estates on Whites Point Road to more modest capes and new subdivisions popping up in the rural zones. Most of the recent growth in town has actually happened in the "rural" areas of this zip code, rather than the village centers, which has been a bit of a headache for local planners trying to keep the town "walkable."
The Steep Falls Zip Code: 04085
Then there’s 04085.
This zip code belongs specifically to Steep Falls. While Steep Falls is technically a village within the town of Standish, it has its own identity and its own post office. It sits way out on the western edge of town, right where Route 113 meets the Saco River.
If your address is in Steep Falls, you use 04085.
It's a smaller, more tight-knit area. The population density is lower, and it feels a lot more "country" than the Standish Corner area. People there often feel a closer connection to the Saco River than they do to Sebago Lake. It’s a subtle vibe shift, but if you live there, you know it.
Quick Facts for Your Mail
If you’re filling out a form or sending a gift, here is the breakdown:
- Main Standish Area: 04084
- Steep Falls Village: 04085
- Post Office Location: 111 Ossipee Trail E, Standish, ME 04084
- Steep Falls Post Office: 2 Main St, Steep Falls, ME 04085
The Standish post office has decent hours, usually 9:00 AM to 4:30 PM on weekdays, and they’re open on Saturday mornings until noon. They don't do passports there, though—you’ll have to head over to Gorham or Windham for that.
What Most People Get Wrong About the Standish Zip Code
One common mistake is thinking that every house in Standish has a Standish mailing address. Because of how the rural routes are drawn, there are some houses on the very edges of town that actually have a Gorham (04038) or Windham (04062) mailing address, even though they pay taxes to Standish.
It’s confusing. I know.
Basically, the USPS cares more about which truck can get to your house the fastest than they do about town tax lines. If you're buying a house near the town line, always check the legal description versus the mailing address. You might be a Standish resident who gets mail from the Gorham postman.
Another weird detail? The "Standish" zip code covers a massive amount of water. About 21 square miles of the town's official area is actually Sebago Lake. So, unless you’re a fish or you live on a boat, a good chunk of the zip code for Standish Maine is just blue space on a map.
Moving to Standish? What to Know
The town has seen a lot of growth lately. In the 2020 census, the population was 10,244, but estimates for 2026 show that number is still climbing as people flee the higher prices in Portland and Westbrook.
The median household income in the 04084 area is roughly $96,000, which is pretty solid for Maine. It’s a town of commuters. The average travel time to work is about 28 minutes, mostly because people are driving into Portland or over to the mall area in South Portland.
If you are moving here, you’ll find:
- Schools: Part of MSAD 6 (Bonny Eagle).
- Utilities: Most of the town is on private wells and septic systems, though some village areas have public water.
- Internet: It’s actually better than you’d think for a rural town; over 94% of households have broadband.
Navigating the Area
If you are visiting, don't just stick to the main drag. The area around 04084 has some of the best hidden gems in Cumberland County.
Johnson Field is a great spot if you have kids. If you’re into hiking, the Standish portion of the Sebago to the Sea Trail is beautiful. And of course, there is the Standish Boat Launch, but you’ll need a resident sticker for that, and the town is pretty strict about it.
Honestly, the best way to handle the zip code situation is to just look up your specific street address on the USPS website if you're right on the border of Steep Falls. Most of the time, 04084 is your winner.
To make sure your mail arrives without a hitch, always include the full four-digit extension if you know it. For the main post office boxes in Standish, that’s usually 04084-9998. For Steep Falls, it's 04085-9998. Using that extra four digits can actually shave a day off your delivery time because it tells the automated sorters exactly which rack to put your mail on.
Actionable Next Steps
If you are moving to the area or need to update your records, here is exactly what to do:
- Verify your exact zone: Use the USPS Zip Code Lookup tool with your full street address to see if you fall under 04084 or 04085.
- Check your tax bill: If your mailing address says Gorham but you think you live in Standish, check your property tax records at the Standish Town Hall to ensure you're registered for the right school district and voting precinct.
- Update your GPS: If you're a business owner in 04084, make sure your Google Business Profile is updated with the correct zip so local customers can find you when they search for services in Standish.
