Amazon Warehouses in Massachusetts: Every Facility Code and Address

Massachusetts has an unusually scattered Amazon network. Where most states concentrate capacity
in two or three towns, Massachusetts spreads it across more than twenty, and no single municipality
holds more than a couple of facilities. I’ve found this catches people out when they try to picture
one big building somewhere. That is a consequence of how the state is built, and it
changes what your tracking is likely to show.

The short version in numbers: 25 Massachusetts facilities on record, 25 of
them carrying a published facility code, spread across 4
distinct facility types. The full breakdown is below.

Came here from a tracking page with a code you did not recognize? The table below carries every Massachusetts facility on our record, with its code, address, and type. Use your browser’s find function. A code that is missing usually belongs to a neighboring state, which in my experience worries people far more than it should.

Every Amazon facility in Massachusetts

25 facilities, of which 25 have a published code: 11 fulfillment centers, 7 delivery stations, 4 sortation centers, 2 distribution centers.

Addresses are compiled from public listings. Amazon opens, closes, and repurposes buildings
continually, and no facility on this list accepts visitors or takes calls about individual
parcels, which is why we do not publish site phone numbers.

The Massachusetts codes people look up most

• OWD9 is a sortation center at 350 Bartlett St in Northborough, which is why so many
  Massachusetts parcels pass through it.
• BOS3 is a fulfillment center at 1450 Osgood St in North Andover.
• SMA2 is a fulfillment center at 1025 Elm St in Bridgewater.
• SMA1 is at 64 Otis St in Westborough, with no type recorded in our listing.

Worcester County leads, and nothing dominates

Worcester County holds the most facilities, ahead of Norfolk and Suffolk counties, then Bristol,
Plymouth, and Middlesex. Milford, Revere, and Northborough appear more than once; almost everywhere
else appears just the once.

The dispersal is a land constraint. Eastern Massachusetts is densely settled with an old
street pattern and very little large contiguous industrial land, so Amazon has taken smaller
buildings in more places rather than a few enormous ones. Worcester County, further west and less
built up, is where the larger floor plates are, which is why it leads despite Boston being the
demand center.

The I-495 belt does most of the work. It arcs around Boston at a distance where land is still
affordable but the city is reachable, and Milford, Northborough, and Franklin sit on it.

For a resident, this means short hops. A Massachusetts parcel typically moves between nearby
facilities rather than traveling far, and the whole state is close enough to the New Jersey and
Connecticut network that inventory frequently arrives from out of state without adding much time.

What it means when your parcel is at one of these

Knowing what kind of building your parcel is sitting in changes how much patience the situation
deserves, and in our experience most people worry at exactly the wrong moment.

Inventory lives at a fulfillment center, so a parcel scanned there has generally not been picked
and packed yet. A sortation center deals only with packed parcels, sorting them toward the right
region. A delivery station is the final stop before a van, and I’d expect delivery within a day
or so of seeing one. Our guide to the different types of Amazon warehouse
covers what happens inside each, and sortation center versus fulfillment center
covers the pair people confuse most.

On the codes themselves, a caution. Amazon does not publish how it names facilities, which
means any lookup table circulating online is somebody’s inference. The leading D for a delivery
station is the one convention that mostly survives scrutiny. For everything else, in our experience
the type column above is the safer guide than anything the letters appear to suggest.

If the parcel has stopped moving entirely, our guide to what a carrier delay means
covers how long to wait before it is worth doing anything, and our guide to
a disappeared order covers the case where
the order itself has vanished from your account rather than the parcel from the network.

If your code is not on this list

Plenty of people arrive here, search for their code, and find nothing. I’d not treat that as a
dead end, because there are only a few explanations and none of them are alarming.

The building is over a state line. Much the commonest reason. Parcel networks pay no attention to
borders, and neighboring states routinely handle each other’s volume. In our experience this accounts
for the large majority of missing codes.

The facility is newer than this listing. Amazon opens buildings continually and no compiled list
keeps pace. If the code looks unfamiliar and recent, that is likely why.

The code belongs to a partner rather than to Amazon. Contracted delivery firms and third-party
logistics providers generate their own scan codes, which never appear on a list of Amazon facilities.

You misread a character. Genuinely common. Zero against O, one against I, five against S. When I
have chased a code that seemed not to exist, roughly half the time it was a transcription slip.

None of these change what you should do, which is wait for the tracking to update rather than
investigate the building.

Other Amazon buildings you may see in tracking

Beyond fulfillment, sortation, and delivery, several other building types appear in tracking,
and each explains a different oddity.

An air hub exists to move freight between regions by plane, so a scan there can put your parcel a
long way from anywhere you expected. A receive center, also called a cross-dock, takes bulk
inbound freight from manufacturers and splits it for onward distribution, meaning nothing inside is
assigned to a customer. Amazon Warehousing and Distribution holds bulk inventory upstream and
tops up fulfillment centers on its own schedule. Returns centers inspect and grade what comes
back. Third-party partner sites are contracted rather than owned, which is why the address
sometimes looks like an ordinary industrial unit.

In our experience these account for most of the tracking scans people cannot make sense of.

Visiting, calling, and collecting

One question worth answering before you ask it: none of these buildings are open to the
public. Fulfillment centers, sortation centers, and delivery stations do not accept visitors, do
not hold parcels for collection, and do not have a desk that will discuss your order. If you need to
collect something, Amazon Locker and Amazon Hub Counter locations are the designated points, and
they are entirely separate from the facilities listed here.

The same goes for phone numbers. Several published lists of Amazon facilities include site numbers,
and I’d ignore them. They ring switchboards that cannot look up an order, and in our experience
people waste an afternoon on that before calling Amazon customer service, which is where the
question belonged in the first place.

What a seller should take from the Massachusetts map

Not a great deal, and it is more honest to say so than to manufacture relevance.

Massachusetts is a strong consumer market: high income, high density, high Amazon penetration. It is
not a place sellers make inventory decisions about, partly because placement is Amazon’s choice
rather than yours, and partly because the state’s facilities are mostly last-mile buildings rather
than storage.

The one point worth carrying away is the same one that applies everywhere and is repeatedly missed:
only fulfillment centers hold seller inventory. Counting Amazon buildings in a state and concluding
you have that many storage options is a misreading of the network, and in our experience it is the
single most common misconception sellers hold about how FBA works.

If your goods are heavy or oversized, note that New England’s older road network and dense
settlement make it a more expensive region to serve, which shows up in fee structures rather than in
anything you can see on this page. Our guide to
shipping options for Amazon sellers
covers the choices that are actually yours to make.

What this page is for, and what it is not. Worth being direct about, because I’ve found
readers assume more precision than any compiled list can offer.

The data comes from public listings, not from Amazon, so it lags reality in both directions:
recently closed sites may persist, recently opened ones may be missing. The type column repeats what
those listings said. In our experience it holds up well, though not perfectly.

Treat the page as a lookup for a code you already have and as a way to place your parcel in the
sequence. I’d not treat it, or any similar list, as an exact census of Amazon’s buildings.

FAQ

How many Amazon warehouses are in Massachusetts?

The full list with codes, addresses, and types appears in the table above. The network is unusually
dispersed, spread across more than twenty municipalities rather than concentrated in a few.

Which Massachusetts county has the most Amazon facilities?

Worcester County, ahead of Norfolk and Suffolk. Worcester leads because it has the larger available
industrial land, even though Boston is the demand center.

Why are Massachusetts Amazon facilities so spread out?

Because eastern Massachusetts is densely settled with an old street pattern and very little large
contiguous industrial land. Amazon has taken smaller buildings in more places rather than a few very
large ones, with much of the activity along the I-495 belt.

What does the code on my Massachusetts tracking mean?

It names a specific building. Search this page for the code to find its address and type. A leading
D usually indicates a delivery station, meaning delivery is close, but Amazon does not publish its
naming scheme so the type column is more reliable.

Why is my Massachusetts parcel coming from Connecticut or New Jersey?

Because Massachusetts sits close enough to the wider Northeast network that inventory frequently
ships from out of state without adding meaningful time. Cross-state movement in tracking is routine
here rather than a sign of a problem.

Can I visit or call an Amazon warehouse in Massachusetts?

No. Fulfillment centers, sortation centers, and delivery stations do not accept visitors or handle
parcel inquiries. Amazon Lockers and Hub Counter locations are the designated collection points.

Last updated: August 29, 2026. Compiled from public listings; Amazon’s facility network changes
continually and this page will lag it. Facilities do not accept visitors or handle parcel
inquiries. For warehouse employment, Amazon’s own hiring site carries current openings and is
the only accurate source.
