If you’re typing Bourne MA zip code into a search bar, you're probably trying to mail a package, set up a utility bill, or maybe you're daydreaming about moving to the Gateway to the Cape. Most people expect a single five-digit string. They want 02532.
That’s the main one. But it isn't the whole story.
Bourne is weird. I mean that in the best way possible, but geographically, it’s a bit of a jigsaw puzzle. It’s the only town in Massachusetts that sits on both sides of the Cape Cod Canal. Because of that physical split—and the way the United States Postal Service (USPS) handles historic villages—you can’t just use one code and hope for the best.
Depending on where you are standing, your zip code might change three times in a ten-minute drive. Honestly, if you use the wrong one for a sensitive delivery, your package might end up sitting in a sorting facility in Wareham or Sandwich while you're staring at an empty porch.
The Big Three: Breaking Down Bourne’s Zip Codes
The primary Bourne MA zip code is 02532. This covers the "town center" area and a massive chunk of the residential land. If you live near the Bourne Bridge or the high school, this is likely your number.
But then we have Buzzards Bay.
Buzzards Bay is technically a village within Bourne, but it carries the zip code 02532 as well. However, many people confuse it with the surrounding areas. Then you have 02559, which belongs to Sagamore Beach. This is the northernmost tip, tucked away on the mainland side of the canal. If you’re at Scusset Beach State Reservation, you’re in 02559 territory.
Wait, there’s more.
02561 belongs to Sagamore. It’s small. It’s specific. It’s mostly for PO Boxes and a tiny slice of the residential area near the Sagamore Bridge. Then you have 02534, which is Cataumet. This is the southern, more coastal-feeling part of town that borders Falmouth.
It's a lot.
- 02532: Bourne, Buzzards Bay, Monument Beach.
- 02559: Sagamore Beach (The mainland side).
- 02561: Sagamore (The bridge area).
- 02534: Cataumet (The south end).
- 02535: Otis Air National Guard Base (Technically its own entity).
Why the Canal Changes Everything
The Cape Cod Canal isn't just a waterway. It's a massive psychological and logistical barrier. When the canal was finished in 1914, it literally cut the town of Bourne in half.

Before the canal, Bourne was just a collection of farming and fishing villages. After the canal? The USPS had to figure out how to route mail across a bridge that, back then, wasn't exactly easy to traverse. This historical legacy is why we have so many distinct identities within one town.
When you use the Bourne MA zip code of 02532, you're essentially tapping into the heart of the town’s infrastructure. This area includes the Bourne Integrated Solid Waste Management facility and the main police station. It's the "working" part of town.
But if you’re looking at real estate in Gray Gables—where President Grover Cleveland used to have his summer White House—you’re still looking at 02532. It’s a wide net.
The Monument Beach Factor
Let’s talk about Monument Beach for a second. Locals call it "Mo Beach."
If you live there, you might feel like you're in a completely different world than someone living in the shadows of the Sagamore Bridge. Yet, you share the 02532 code. This is where the USPS gets a little lazy with naming conventions. Even though Monument Beach has its own post office on Shore Road, your mail will still say Bourne, MA 02532.
Why does this matter?
Insurance companies.
When you're getting a quote for homeowners insurance, that Bourne MA zip code tells the insurance company how close you are to the water. 02532 covers both inland woods and high-risk flood zones. If you're buying a house, don't just rely on the zip code for your "closeness to the coast" metrics. A house in 02532 could be 50 feet from the surge or 5 miles away.
The Military Zone: 02542 and Joint Base Cape Cod
One thing that confuses the heck out of people moving to the area is the military presence. Joint Base Cape Cod (formerly Otis Air Force Base) occupies a huge chunk of land that technically sits within Bourne, Sandwich, and Mashpee.
If you are active duty or living on the base, your zip code is 02542.

It’s an "exclusive" zip code. If you try to send a pizza to 02542 from a shop that only services 02532, you might run into some friction. The base has its own internal mail system, its own gates, and its own rules. It’s a town within a town.
Common Mistakes People Make
Most people think that because Bourne is a "small" town (around 20,000 residents), the zip code is interchangeable.
It’s not.
If you’re looking for the Massachusetts Maritime Academy, you’re looking for 101 Academy Drive in Buzzards Bay. Use 02532. If you use 02559, your GPS might try to take you across the canal to the Sagamore side, and during the summer, that’s a 45-minute mistake you don't want to make. Trust me. The bridge traffic is no joke.
Another big one: Sagamore vs. Sagamore Beach.
Sagamore (02561) is largely the area surrounding the bridge on the Cape side. Sagamore Beach (02559) is on the "off-Cape" or mainland side. If you get these mixed up, you’re literally on the wrong side of the water.
How to Verify Your Specific Address
If you're unsure, don't guess. The USPS has a "Look Up a Zip Code" tool that is surprisingly accurate for Bourne's weird borders.
- Go to the official USPS website.
- Enter the full street address.
- Pay attention to the "Last Line" data.
Sometimes, the "acceptable city name" will be Buzzards Bay, but the "preferred city name" will be Bourne. Both work for the Bourne MA zip code of 02532, but using the village name often helps local delivery drivers find your house faster if you live in a confusing subdivision.
Economic Impact of the Zip Code
It sounds crazy, but those five digits change your cost of living.
Cataumet (02534) is often associated with higher property values. It feels more like the "Outer Cape" or "The Islands" because of its proximity to North Falmouth and Megansett. When you see a listing with 02534, the price tag usually reflects that "Village of Cataumet" prestige.

On the flip side, 02532 is the backbone. It’s where the grocery stores are. It’s where the commuters live because it’s the easiest point to jump on Route 25 or Route 28.
Moving to Bourne? Here is the Playbook
If you are relocating, you need to be specific with your utilities. Eversource (electric) and National Grid (gas) are usually pretty good with the Bourne MA zip code nuances, but the Bourne Water District and the North Sagamore Water District are separate entities.
Your zip code—and specifically your village—determines who you pay for water.
- North Sagamore Water District: Generally serves the 02559 and 02561 areas.
- Bourne Water District: Covers the bulk of the 02532 area.
- Buzzards Bay Water District: Specifically for the village of Buzzards Bay.
It’s a fragmented system. That’s just Cape Cod life.
Actionable Steps for Residents and Visitors
If you're dealing with the Bourne MA zip code for anything official, keep these points in mind to avoid headaches.
Check your flood zone regardless of zip. Just because 02532 isn't "The Hamptons" doesn't mean you aren't in a velocity zone. Use the FEMA Flood Map Service Center.
Mind the bridges. If you’re setting up a delivery (like furniture or appliances), explicitly tell the company which side of the canal you are on. Many companies see "Bourne 02532" and don't realize they might have to pay a toll or sit in bridge traffic to reach you.
Use PO Boxes for reliability. If you live in one of the smaller villages like Sagamore, sometimes getting a PO Box at the local village post office is faster than home delivery. The mail doesn't have to travel to the central sorting facility and back out to a rural route.
Verify for Taxes. If you are buying a car, make sure the dealership uses your correct village-based zip code. It can occasionally affect small local tax assessments or insurance garaging codes.
Bourne is a gateway. It’s the transition from the "real world" to the "Cape world." Its zip codes reflect that messy, beautiful transition. Whether you're in the 02532 heartland or the 02534 coastal edge, you're part of a town that refuses to be just one thing.
Stop thinking of it as just a number. It's your coordinates in a town that literally straddles a sea-level waterway. That's pretty cool when you think about it.
Always double-check your village. Never trust a GPS blindly near the canal. And if you're mailing something to the Maritime Academy, for heaven's sake, make sure it says Buzzards Bay 02532.
