Amazon Warehouses in Pennsylvania: Every Facility Code and Address

Pennsylvania is the state that quietly serves the American Northeast. It holds one of the densest
concentrations of fulfillment capacity in the country, and almost none of it exists to serve
Pennsylvanians. The buildings are there because the New York and Philadelphia markets are close and
the land is not New York or New Jersey land. I’d call it the most under-discussed logistics state in
the country.

The short version in numbers: 41 Pennsylvania facilities on record, 35 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 Pennsylvania 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 Pennsylvania

41 facilities, of which 35 have a published code: 22 fulfillment centers, 11 delivery stations, 6 distribution centers, 2 sortation 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parcels, which is why we do not publish site phone numbers.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 Pennsylvania codes people look up most

Pennsylvania generates more code searches than almost any state, so these are worth naming
individually.

• MDT9 is a distribution center at 251 Westwood HL in Frailey Township.
• MDT4 is a fulfillment center at 5125 Commerce Dr in York.
• LBE1 is a fulfillment center at 165 Glenn Fox Rd in New Stanton, in the western half of the
  state.
• WBW2 is a fulfillment center at 1300 Corporate Way in Olyphant, near Scranton.
• DPL2 is a delivery station at 7125 Grayson Rd in Harrisburg, so a parcel there is close to
  arriving.

The MDT prefix comes from Harrisburg International Airport’s code, which is a useful reminder that
the letters often reference the nearest airport rather than the town on the address.

The I-81 and I-78 corridor, and why it exists

Allegheny and Cumberland counties lead on facility count, with Berks and Philadelphia close behind,
then Lackawanna and York. By town, Philadelphia leads, then Carlisle, with Imperial, Shippensburg,
Breinigsville, Reading, and Lewisberry each holding two.

That list is really one corridor. Carlisle, Shippensburg, Lewisberry, and York sit along I-81 near
Harrisburg. Breinigsville and Reading sit on the I-78 run through the Lehigh Valley. Together they
form a band of warehousing roughly 100 miles long that can reach New York City, Philadelphia,
Baltimore, and Washington inside a single driving day, on land that cost a fraction of what the same
building would cost in New Jersey.

Allegheny County is a separate business. Pittsburgh and the sites around Imperial and New Stanton
face west toward Ohio rather than east toward the coast.

The practical consequence is that Pennsylvania codes appear in tracking all over the Northeast.
If you live in New York, New Jersey, Maryland, or Delaware and see one, nothing has gone wrong. In
our experience this is the single most common source of confused tracking questions in the region.

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.

Why Pennsylvania is where the network wants your stock

Pennsylvania is one of the few states where Amazon’s placement logic is obviously and defensibly
correct, which makes complaining about placement pointless here.

Inventory in the Harrisburg or Lehigh Valley corridor reaches roughly a fifth of the United States
population overnight by truck. That is why so much of Amazon’s east coast capacity sits there, and
why third-party prep and storage providers have followed.

You still do not choose it. Send to Amazon assigns your inbound destination from Amazon’s own
network planning. What you can influence is the inbound leg, and Pennsylvania is well served by
carriers moving freight from the New York and New Jersey ports inland. Our guide to
shipping options for Amazon sellers
covers the routes that are genuinely your decision.

Only fulfillment centers hold seller inventory. The delivery stations and sortation centers in the
table above never will, whatever their location.

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 Pennsylvania?

The complete list with codes, addresses, and types appears in the table above. Pennsylvania holds one
of the densest concentrations of fulfillment capacity in the country, most of it serving markets
outside the state.

Which Pennsylvania county has the most Amazon facilities?

Allegheny and Cumberland counties are level at the top, with Berks and Philadelphia close behind,
then Lackawanna and York. The Cumberland, York, and Berks sites form the I-81 and I-78 distribution
corridor.

What is MDT9 and where is it?

MDT9 is a distribution center at 251 Westwood HL in Frailey Township. The MDT prefix comes from
Harrisburg International Airport’s code, which is a good illustration of how Amazon’s facility
letters frequently reference the nearest airport rather than the town.

Why does my tracking show a Pennsylvania facility when I live in New York?

Because Pennsylvania serves the whole Northeast. The Harrisburg and Lehigh Valley corridor reaches
New York City, Philadelphia, Baltimore, and Washington within a driving day, so its codes appear in
tracking across the region routinely.

Why are there so many warehouses near Harrisburg and Allentown?

Because I-81 and I-78 put a truck within a day of roughly a fifth of the United States population,
on land costing a fraction of the equivalent site in New Jersey. That combination is unusual and it
is the whole reason the corridor exists.

Can a seller choose a Pennsylvania fulfillment center?

No. Amazon assigns inbound destinations through Send to Amazon. Pennsylvania is where the network
often routes inventory anyway, so Amazon’s planning and a seller’s interest tend to align here more
than in most states.
