Amazon Warehouses in Michigan: Every Facility Code and Address

Michigan’s Amazon network is built on infrastructure that was already there. Wayne County holds
more facilities than the next two counties combined, and the reason is that southeast Michigan was
purpose-built for moving physical goods long before Amazon existed. The warehouses went where the
freight infrastructure already was.

The short version in numbers: 25 Michigan facilities on record, 23 of
them carrying a published facility code, spread across 4
distinct facility types. The full breakdown is below.

If you are trying to identify a code from your tracking, start with the table below. It lists every Michigan facility we hold, alongside its address and type. Search the page for your code. Codes that do not appear here generally sit just over a state line, and I’d treat that as ordinary rather than alarming.

Every Amazon facility in Michigan

25 facilities, of which 23 have a published code: 11 fulfillment centers, 7 delivery stations, 4 sortation centers, 3 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parcels, which is why we do not publish site phone numbers.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 Michigan codes people look up most

• LAN2 is a fulfillment center at 6500 W Mt Hope Hwy in Lansing.
• DET6 is a fulfillment center at 20110 Woodward Ave in Detroit.
• DET3 is a fulfillment center at 1220 Featherstone Rd in Pontiac.
• XSA1 is a delivery station at 2266 Northway Dr in Mt Pleasant.

DET6 and DET3 are worth pausing on. Both carry a D prefix, which usually signals a delivery station,
and our listing records both as fulfillment centers. In our experience Michigan is one of the states
where the prefix convention breaks down most visibly, so read the type column rather than the
letters.

Detroit, Grand Rapids, and the Upper Peninsula problem

Wayne County leads decisively, followed by Kent County around Grand Rapids, then Oakland, Macomb, and
Eaton. Romulus and Caledonia hold three sites each, with Livonia, Lansing, Pontiac, Walker, and
Plymouth holding two.

Romulus is the tell. It sits beside Detroit Metropolitan Airport, and its cluster exists for the same
reason the airport does. The wider Wayne, Oakland, and Macomb spread follows the industrial corridor
built for the automotive industry, which left behind exactly the rail links, interstate access, and
large flat sites a fulfillment network wants.

Kent County is the second engine, serving western Michigan out of Grand Rapids, Caledonia, and Walker.
Lansing, in Eaton County, covers the middle of the state.

The Upper Peninsula is the honest gap. Our listing shows nothing there. The UP is served from
Wisconsin and from downstate, across long distances and, for much of the year, difficult weather. I’d
expect delivery promises there to look more like rural Alaska than like Detroit, and that is not going
to change, because the population does not justify a building.

What it means when your parcel is at one of these

The type of building tells you how far along the journey is. I’ve found that single distinction
resolves most of the anxiety people arrive with.

A fulfillment center is where inventory sits, so your order has probably not been packed. A
sortation center only ever sees packed parcels and groups them by region. A delivery station
is the last building before the van, so a parcel there is normally close to home. 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.

One caveat about the codes. The naming scheme has never been published by Amazon, so
decoders you find elsewhere are guesswork dressed as documentation. A leading D does reliably tend to
indicate a delivery station. Past that, I’d trust the type column in the table rather than trying to
read meaning into three letters, since I’ve found the exceptions turn up constantly.

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

If you have searched this page and come up empty, that is a normal outcome rather than a
problem, and I’d resist the urge to read anything into it. Four explanations cover almost every case.

It is a facility in an adjoining state. By far the most likely. Distribution networks ignore
state boundaries entirely, and in our experience people are far more surprised by this than the
logistics justify.

It opened after this listing was compiled. Amazon adds buildings constantly and any published
list trails reality by some margin.

It is a partner code, not an Amazon one. Contracted carriers and third-party logistics firms
issue their own facility identifiers that will never appear here.

The characters were misread. Zero and O, one and I, five and S all trip people up. I’ve found
this explains a surprising share of codes that appear not to exist.

In every one of those cases the useful response is the same: let the tracking update rather than
chase the building.

Other Amazon buildings you may see in tracking

A handful of other facility types show up in tracking, and knowing them removes a lot of
needless worry.

Air hubs exist to fly freight between regions rather than to pick orders, so a scan at one can
place your parcel somewhere that looks like a detour and is not. Receive centers, or cross-docks,
accept bulk freight direct from manufacturers and break it down for distribution, so nothing there
belongs to a customer yet. Amazon Warehousing and Distribution sites store bulk stock upstream
and replenish fulfillment centers automatically. Returns centers grade returned merchandise.
Third-party partner sites are leased or contracted buildings rather than Amazon-owned ones.

When I have followed an unusual scan back, it has almost always been one of these rather than a
fault.

Visiting, calling, and collecting

A point people frequently test before believing: these are not places you can visit.
Fulfillment centers, sortation centers, and delivery stations take no visitors, release no parcels
over a counter, and staff no desk that can discuss an individual order. Collection happens at Amazon
Locker and Amazon Hub Counter locations instead, which have nothing to do with the buildings above.

Phone numbers deserve the same treatment. Some facility lists publish them; I’d skip them entirely.
They reach switchboards with no access to order records, and in my experience the call achieves
nothing that Amazon customer service would not have handled immediately.

Michigan for sellers: two markets, not one

The useful Michigan insight is about your customers rather than your inventory, since
inbound placement is assigned by Amazon and only fulfillment centers hold seller stock.

Michigan behaves as two markets. Southeast Michigan is dense, well-served, and fast. The rest of
the state, and particularly the Upper Peninsula, is not. If your sales skew toward northern Michigan,
expect longer delivery promises and a slightly higher rate of weather-related delays between December
and March.

There is also a cross-border consideration that rarely gets mentioned. Detroit is the busiest
commercial land crossing on the Canadian border, which matters if you source from or sell into Canada.
Our guide to Amazon Global Selling covers whether
operating in a second marketplace is worth the compliance overhead, and the answer is often no until
volume justifies it.

Michigan’s automotive supply base also makes it a practical place to source certain manufactured and
industrial goods domestically, which is worth knowing if import lead times are hurting you.

How to read this page, and what it cannot tell you. I’d rather set expectations than have
you draw the wrong conclusion from a table.

The list is compiled from public listings, so it lags Amazon’s actual network and always will. A
building that closed last quarter may still appear; one that opened last month probably does not.
The type column reflects what those listings recorded, and in our experience it is right far more
often than not, without being infallible.

What the page is genuinely good for is identifying a code you have in front of you and working out
roughly where your parcel sits in the chain. What it is not good for is counting Amazon’s real estate
precisely, and I’d treat any site claiming an exact national figure with some suspicion.

FAQ

How many Amazon warehouses are in Michigan?

The complete list with codes, addresses, and types appears in the table above. The network concentrates
heavily in southeast Michigan, with a second cluster around Grand Rapids.

Which Michigan county has the most Amazon facilities?

Wayne County, which holds more than the next two counties combined, followed by Kent County around
Grand Rapids, then Oakland, Macomb, and Eaton.

Why are there so many Amazon facilities in Romulus?

Because Romulus sits beside Detroit Metropolitan Airport. The cluster exists for the same reason the
airport does, and it inherits the rail links, interstate access, and large flat sites built for the
automotive industry.

Does Amazon have warehouses in the Upper Peninsula?

Not in our listing. The Upper Peninsula is served from Wisconsin and from downstate across long
distances, which makes delivery promises there considerably longer than in the Detroit metro,
particularly in winter.

What is DET6 and is it a delivery station?

DET6 is recorded in our listing as a fulfillment center at 20110 Woodward Ave in Detroit, despite the
D prefix that usually signals a delivery station. Michigan is one of the clearer examples of why the
type column is more reliable than the code letters.

Is Michigan useful to sellers beyond as a market?

Mainly through Detroit’s position as the busiest commercial land crossing on the Canadian border, and
through the state’s automotive supply base for domestic sourcing. Inbound placement into Amazon’s
network remains Amazon’s decision.

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.
