Auburn, MA Zip Codes: Complete List, Map, and County Guide for 2026

Auburn, MA runs on a single primary zip code for all its postal addresses. Anyone buying a home in Auburn, MA will find a fast-moving market - median home prices sitting around $479,000 as of late 2026, roughly 35 homes available at any given moment, and a median time on market of just 23 days.

That's a tight setup. Knowing how the local zip code boundaries work, and where they bump up against neighboring towns, helps you get clear on exactly where a property sits within the Worcester metro area before you start making offers.

The Primary Zip Code for Auburn, MA

The United States Postal Service designates one standard zip code for Auburn: 01501. One code, entire town. Whether you're mailing a letter or registering a vehicle to a property inside the municipal limits, 01501 is what goes on the envelope.

That simplicity is useful when you're searching for homes. You don't have to sort through multiple Auburn-specific codes to find listings in different parts of town - the 01501 boundary covers it all, roughly 16,700 residents based on recent postal data.

That said, postal routes don't always line up perfectly with town lines. A home sitting right on the Auburn border might technically receive mail from a neighboring post office. It happens. But 01501 remains the only Auburn-designated code regardless.

Overlapping Zip Codes on the Auburn Border

Several zip codes from neighboring towns cross slightly into the Auburn municipal boundary. These include 01527, 01540, 01542, 01603, 01607, 01610, and 01611 - codes that belong to nearby postal cities like Millbury, Oxford, Worcester, Rochdale, and Cherry Valley.

A property in one of these border zones might physically sit within Auburn and pay Auburn property taxes while carrying a Worcester or Oxford mailing address. If you're looking at anything on the edge of town, verify the actual taxing municipality before you get too far down the road on a deal.

Understanding the Auburn Zip Code Map

The 01501 boundary traces Auburn's roughly 16.4 square miles. Worcester sits to the north, Millbury to the east, Oxford to the south, and Leicester to the west. The Massachusetts Turnpike (I-90), I-290, and I-395 all intersect directly within this single zip code - which tells you a lot about why this area draws commuters heading toward Boston or Connecticut.

That highway access shapes demand in real, measurable ways. Properties near the major interchanges tend to move quickly, and it's a contributing factor to the town's current two-month supply of housing inventory. When supply is that thin and location is that convenient, you feel it in the offers.

Worcester County and the Auburn Area

Auburn is in Worcester County and falls within the Worcester, MA-CT Metropolitan Statistical Area - Central Massachusetts, with a foot in the outer edge of the Greater Boston area. Suburban, but connected.

Worcester County handles regional services, though Auburn runs its own local town government and public school district. Any real estate listing in 01501 falls under Worcester County jurisdiction for property recording and registry of deeds.

Auburn Neighborhoods Within the 01501 Boundary

All of Auburn's recognized neighborhoods - Pakachoag, Stoneville, Oxford Heights, Town Center, and Auburn Northwest - sit inside the 01501 boundary. Pakachoag is in the eastern part of town and includes the Pakachoag Golf Course, a town-owned facility that also happens to be the Goddard Rocket Launching Site, a National Historic Landmark where Dr. Robert H. Goddard launched the world's first liquid-fueled rocket in 1926.

Town Center and Pondville put you closer to municipal buildings and local retail. Oxford Heights, in West Auburn, runs right up to the Oxford town line.

Stoneville and Drury Square

Stoneville and Drury Square represent a more densely developed pocket of 01501 - older, established homes, closer to local commercial routes. If you're someone who wants character and a real neighborhood feel rather than newer construction on a cul-de-sac, this part of town is worth a look.

Homes here sell fast and frequently above list price, which tracks with the town's current 101.7% average sale-to-list ratio. That number isn't an anomaly - it's the baseline.

Telephone Area Codes for Auburn

Residents in the 01501 zip code use two area codes: 508 and 774. The 508 code is the original designation for Central Massachusetts, Southeastern Massachusetts, and Cape Cod. The 774 code was added later as an overlay covering the exact same geographic region.

Because they operate as an overlay, Auburn residents dial the full ten-digit number for local calls. Both codes are standard across local businesses, municipal offices, and residential landlines throughout town.

How to Find Your Full 9-Digit Zip Code in Auburn

The standard Auburn address uses the five-digit 01501 code, but the USPS assigns a full nine-digit ZIP+4 code to every specific delivery point. Those extra four digits identify a geographic segment within 01501 - a city block, a group of apartments, an individual business - so the postal service can route mail more precisely.

To find the exact ZIP+4 for a specific property, use the official USPS Zip Code Lookup tool. Enter the street address, city, and state, and it returns the standard 01501 followed by the four-digit routing extension for that address.

Real Estate and Living in Auburn's 01501 Area

More than half of Auburn's recent sales closed above asking - 55.8% of properties, to be exact. With a median of just 23 days on market, this is not a place where you take your time deciding. Get your financing sorted before you start touring, and know what you want going in.

One thing that works in buyers' favor here: because Auburn operates under a single zip code, you're not trying to decode which postal zone is "better." Housing decisions come down to neighborhood character, commute times to the Mass Pike or I-290, and proximity to things like local parks or the Pakachoag Golf Course. That's a cleaner calculus than most towns in the Worcester metro offer.
