Amazon Warehouses in Wisconsin: Every Facility Code and Address

Wisconsin’s Amazon map has an obvious tell once you look at it. Kenosha County holds more
facilities than Milwaukee County, which makes no sense until you notice that Kenosha sits on the
Illinois state line, roughly an hour from downtown Chicago.

Much of Wisconsin’s capacity is not there to serve Wisconsin.

The short version in numbers: 18 Wisconsin facilities on record, 16 of
them carrying a published facility code, spread across 4
distinct facility types. The full breakdown is below.

Looking up a code you saw on a tracking page? Every Wisconsin facility we have on record is in the table below with its code, address, and type. Search this page for your code. If it is not here, it is most likely a building in a neighboring state, because parcels cross state lines routinely on the way to you and I’d not read that as a problem.

Every Amazon facility in Wisconsin

18 facilities, of which 16 have a published code: 7 delivery stations, 6 fulfillment centers, 2 distribution centers, 1 sortation center.

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parcels, which is why we do not publish site phone numbers.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 Wisconsin codes people look up most

• HMK4 is a delivery station at 16555 W Small Rd in New Berlin, west of Milwaukee.
• SWI1 is a distribution center at W232N2950 Roundy Cir E in Pewaukee.
• DML8 is a delivery station at 1925 Grandview Pkwy in Sturtevant, between Milwaukee and Kenosha.
• JVL1 is a fulfillment center at 1255 Gateway Blvd in Beloit, on the Illinois state line.

JVL is the airport code for Janesville, which sits near Beloit, and DML relates to the Milwaukee area.
Three of the four are last-mile or transfer buildings, so a parcel showing one is usually close to
delivery.

Kenosha serves Chicago, Milwaukee serves Wisconsin

Kenosha County leads, with Milwaukee and Waukesha counties level behind it, then Dane. By town,
Kenosha leads clearly, followed by Madison and Milwaukee.

Kenosha is a Chicago play. It sits on I-94 between Milwaukee and Chicago, about 35 miles south
of Milwaukee and roughly 60 miles north of the Loop, which is close enough to serve the northern
Chicago suburbs in about 1 hour and far enough out that land is affordable. Beloit does the same thing
on the other side of the state, sitting on the Illinois line near Rockford.

Milwaukee and Waukesha are the genuine Wisconsin network, covering the state’s largest metro and
its western suburbs. Dane County covers Madison, about 80 miles west, and the middle of the state.

Northern Wisconsin is thin. The population is sparse and the distances are long: Superior sits
roughly 380 miles from Kenosha, and Wausau about 190 miles from Milwaukee. Winter compounds both,
typically adding 1 to 2 days on the worst weeks between December and March. I’d expect delivery
promises around Green Bay, Wausau, and Superior to run longer than in the southeast corner, and the
Upper Peninsula of Michigan is partly served from here too.

Expect Illinois codes in your tracking constantly, particularly in the southern half of the state.
The two networks are effectively continuous, and in our experience Wisconsin residents find that more
surprising than they should.

What it means when your parcel is at one of these

The facility type tells you roughly how far along your parcel is, and I’d argue that is the
single most useful thing on this page after the addresses themselves.

A fulfillment center holds inventory, so a parcel there has usually not been packed for you yet.
A sortation center handles parcels that are already packed, grouping them by destination region.
A delivery station is the last building your parcel sees before it goes onto a van, which means
it is close to you and close to arriving. 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.

A word on the codes themselves. Amazon has never published its facility naming scheme, so
every decoder you find online is inference rather than documentation. One pattern does hold up
reasonably well: a leading D usually means a delivery station. Beyond that I’d read the type column
above rather than the letters, because the exceptions are common enough to mislead you.

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

Searched and found nothing? That happens often, and I’d read it as unremarkable. The
possibilities are few.

The building sits in a neighboring state. The single most common answer. Parcel networks are
built around drive times rather than state lines, and in our experience a cross-border scan worries
people who have no reason to be worried.

The site is newer than this page. Amazon commissions buildings faster than any list is updated,
so recent codes are frequently absent.

It is not an Amazon code at all. Contracted delivery partners and third-party logistics providers
run their own identifiers, which look similar and are not the same thing.

A character was misread somewhere. Zero versus O, one versus I, five versus S. When I have run
down a code that seemed impossible, a misread character was often the whole story.

Whichever applies, the sensible move is to wait for the next tracking update rather than to
investigate the address.

Other Amazon buildings you may see in tracking

Five other kinds of Amazon building turn up in tracking often enough to be worth naming, and
none of them behave like the ones above.

Air hubs move freight between regions by aircraft rather than picking orders, which is why a
parcel can appear hundreds of miles from both its origin and its destination without anything having
gone wrong. Receive centers, sometimes labeled cross-docks, take bulk shipments from
manufacturers and break them apart for distribution; nothing there is destined for a customer yet.
Amazon Warehousing and Distribution sites hold bulk stock upstream and replenish fulfillment
centers automatically, which matters to importers and is largely unknown among smaller merchants.
Returns centers grade what customers send back. And third-party partner sites are buildings
Amazon uses without owning, which is why some addresses look nothing like a warehouse.

I’d not read too much into seeing one. They are ordinary stages in a long chain.

Visiting, calling, and collecting

Worth stating plainly, because it comes up constantly: you cannot visit any of these
sites. Fulfillment centers, sortation centers, and delivery stations admit no members of the
public, hand out no parcels, and run no inquiry desk. Amazon Locker and Amazon Hub Counter locations
are the designated collection points and are unrelated to the facilities in this table.

Facility phone numbers, where other lists publish them, are the same trap. When I have followed one
up it reached a switchboard with no visibility of orders at all, so the useful route is Amazon
customer service rather than the building.

What Wisconsin means for a seller

Mainly it means proximity to Chicago without Chicago’s costs, which is a pattern repeated across this
whole cluster and is worth naming once properly.

Amazon builds where land is affordable and demand is reachable, not where the demand actually lives.
Kenosha, Beloit, and the Illinois border towns exist because of that trade. The state a facility sits
in tells you very little about the market it serves, and I’d carry that idea into every state page
you read, including this one.

For a seller the practical consequences are the same as everywhere. Amazon assigns your inbound
destination through Send to Amazon, and only fulfillment centers hold your inventory. Wisconsin’s
list is mostly delivery stations.

If you sell heavy or oversized goods, note that winter in the upper Midwest genuinely affects delivery
reliability between December and March, and a late delivery affects your On-Time Delivery Rate whether
or not the weather caused it. Our guide to
what a carrier delay means covers that
asymmetry.

A note on how much weight to put on this list. I’ve found it helps to say plainly what a
page like this can and cannot do.

Everything here comes from public listings rather than from Amazon, which means it trails the real
network. Closed buildings linger; new ones take a while to appear. The type column carries whatever
those listings recorded, and in our experience that is usually accurate rather than always accurate.

Use the page to identify a code and to understand what stage your parcel has reached. Do not use it
to count Amazon’s footprint exactly, and I’d be wary of anyone who claims to.

FAQ

How many Amazon warehouses are in Wisconsin?

The complete list with codes, addresses, and types appears in the table above. Kenosha County holds
more facilities than Milwaukee County, which reflects how much of the capacity serves Chicago rather
than Wisconsin.

Why does Amazon have so many facilities in Kenosha?

Because Kenosha sits on I-94 on the Illinois state line, roughly an hour from downtown Chicago. It is
close enough to serve the northern Chicago suburbs and far enough out that land is affordable.

Which Wisconsin county has the most Amazon facilities?

Kenosha County, followed by Milwaukee and Waukesha counties level behind it, then Dane County around
Madison.

Why does my Wisconsin tracking show an Illinois facility?

Because the two networks are effectively continuous across the state line, particularly in the
southern half of Wisconsin. Illinois codes in Wisconsin tracking are routine rather than a routing
error.

Is Amazon delivery slower in northern Wisconsin?

Yes. The population is sparse, distances are long, and winter compounds both, so delivery promises
around Green Bay, Wausau, and Superior run longer than in the southeast corner.

Does Wisconsin store much seller inventory?

Less than the facility count suggests. Most Wisconsin entries are delivery stations, and only
fulfillment centers hold seller inventory. Sellers cannot choose their inbound destination in any
case.

Last updated: August 30, 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
