Amazon Warehouses in Maryland: Every Facility Code and Address

Maryland packs a lot of Amazon capacity into a small state, and it does so for two reasons that have
nothing to do with each other: the Port of Baltimore, and the Washington DC metropolitan area.
Delivery stations outnumber every other type here, which reflects how much of Maryland’s job is
getting parcels the last few miles.

The short version in numbers: 33 Maryland facilities on record, 27 of
them carrying a published facility code, spread across 5
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 Maryland 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 Maryland

33 facilities, of which 27 have a published code: 12 delivery stations, 8 fulfillment centers, 3 sortation centers, 2 aas, 1 distribution 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parcels, which is why we do not publish site phone numbers.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 Maryland codes people look up most

• DLD1 is a delivery station at 7659 Solley Rd in Pasadena, near Baltimore.
• DMD9 is a delivery station at 1000 Prince Georges Blvd in Upper Marlboro, serving the DC side of
  the state.
• MTN8 is at 811 Wesel Blvd in Hagerstown, with no type recorded in our listing.
• KRB5 is searched frequently but does not appear in our Maryland listing, and we would rather say
  so than publish an address we cannot support.

Two of the three we can place are delivery stations, so a parcel showing one of those is normally
close to arriving.

A port, a capital, and a former steel mill

Baltimore City holds the most facilities, with Prince George’s and Anne Arundel counties level behind
it, then Baltimore County, Harford, and Washington County out west. Baltimore leads by town, followed
by Hagerstown.

The Baltimore concentration follows the port, which is one of the larger east coast container
terminals and is unusual in handling a great deal of roll-on cargo alongside boxes. The Prince
George’s and Anne Arundel sites face Washington DC, serving a dense, affluent market that has almost
no warehouse land of its own.

Sparrows Point deserves its own mention. The site is the former Bethlehem Steel works, once one of
the largest steel mills in the world, and it has been redeveloped into a logistics complex with a
significant Amazon presence. I’ve found that piece of history explains more about Maryland’s map than
any amount of interstate analysis: the land existed, it was already industrial, and it sat next to
deep water.

Hagerstown, out on I-81, is a different play again. It is on the same corridor as the Pennsylvania
sites and serves the same broad region rather than serving Maryland.

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.

Maryland for sellers: the port and the promise

Maryland’s relevance to a seller is inbound rather than storage.

The Port of Baltimore is a practical east coast entry point, and it is less congested than the New
York and New Jersey terminals that most importers default to. For goods arriving from Europe or via
the Suez route it can be a sensible alternative, and the warehousing around it is cheaper than the
equivalent in New Jersey. Our guide to
finding a reliable shipping agent
covers moving freight from a port into Amazon’s network without the rejections inexperienced
forwarders produce.

The second point is about the market rather than the buildings. The Washington and Baltimore corridor
is one of the wealthiest in the country, and delivery speed converts well there. That is an argument
for keeping inventory in stock rather than for trying to place it geographically, since
placement is not a seller decision. Send to Amazon assigns your destination.

Only fulfillment centers hold seller inventory, and Maryland’s list is dominated by delivery
stations.

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 Maryland?

The complete list with codes, addresses, and types appears in the table above. Maryland holds
substantial capacity for its size, split between the Port of Baltimore and the Washington DC market.

Which Maryland county has the most Amazon facilities?

Baltimore City, with Prince George’s and Anne Arundel counties level behind it, then Baltimore
County, Harford, and Washington County.

What is at Sparrows Point?

Sparrows Point is the former Bethlehem Steel works, once among the largest steel mills in the world,
now redeveloped as a logistics complex with a significant Amazon presence. The land was already
industrial and sits beside deep water, which is why it was converted rather than replaced.

What is DLD1 and where is it?

DLD1 is a delivery station at 7659 Solley Rd in Pasadena, Maryland, near Baltimore. As a delivery
station it handles parcels that are already packed, so an item scanned there is usually close to
delivery.

Why does Amazon have facilities in Hagerstown?

Because Hagerstown sits on I-81, the same corridor as the large Pennsylvania distribution sites. Those
facilities serve a broad multi-state region rather than serving Maryland specifically.

Is Baltimore a good port for Amazon sellers importing goods?

It can be. The Port of Baltimore is a practical east coast entry point and is generally less congested
than the New York and New Jersey terminals, with cheaper warehousing nearby. Placement into Amazon’s
network is still assigned by Amazon.

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.
