Amazon Warehouses in Washington: Every Facility Code and Address

Washington is where Amazon started, and the state’s network still reflects that. King County alone
holds more than double the facilities of any other county, and the Kent Valley south of Seattle
remains the operational core more than two decades after the company outgrew it.

Washington also holds a higher share of grocery and Prime Now sites than most states, which is why the
most searched code here is not a fulfillment center at all.

The short version in numbers: 30 Washington facilities on record, 29 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 Washington 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 Washington

30 facilities, of which 29 have a published code: 13 fulfillment centers, 7 delivery stations, 4 grocery or prime now sites, 3 distribution centers, 3 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parcels, which is why we do not publish site phone numbers.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 Washington codes people look up most

• UWA6 is recorded in our listing as a grocery and Prime Now site at 20202 84th Ave S in Kent, and
  it draws far more searches than any other Washington code. Worth noting because most people assume a
  heavily searched code must be a large fulfillment center, and here it is not.
• BFI9 is a fulfillment center at 3230 International Pl in DuPont.
• PAE2 is a fulfillment center at 4620 172nd St NE in Arlington.
• PSC2 is a fulfillment center at 1351 S Rd 40 E in Pasco, in eastern Washington.

BFI and PAE are the airport codes for Boeing Field and Paine Field, which is a distinctly Washington
touch: the state has enough aviation infrastructure that Amazon reaches past Sea-Tac for its
markers.

The Kent Valley, and everything after it

King County leads by a wide margin, with Pierce County second, then Snohomish, Spokane, and
Thurston. By town, Kent holds the most, followed by Everett, DuPont, Sumner, Tukwila, and Seattle.

The Kent Valley is the historic heart of it. Kent, Sumner, Auburn, and Tukwila sit on flat
industrial land between Seattle and Tacoma, close to the ports of Seattle and Tacoma and to I-5. That
combination made the valley a warehousing district long before ecommerce, and Amazon inherited it.

Pierce County extends the same corridor south through DuPont and Sumner. Snohomish County, around
Everett and Arlington, serves the northern suburbs and the Canadian border traffic.

Spokane is the exception. It sits roughly 280 miles east across the Cascades and serves eastern
Washington, northern Idaho, and parts of Montana. I’d treat it as a separate network rather than as a
spoke, because the mountain crossing makes serving it from Seattle impractical in winter.

Seattle itself holds relatively little storage for its size, for the usual reason: the land is
expensive and the topography is difficult.

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.

Washington for sellers: the ports and a tax note

Two points, and the second one comes up constantly.

Seattle and Tacoma together form a major west coast container gateway, and they are meaningfully
less congested than the southern California ports. For goods arriving from Asia destined for the
Pacific Northwest or for rail transfer eastward, it is a genuine alternative worth pricing. Our guide
to finding a reliable shipping agent
covers choosing a forwarder that understands FBA inbound requirements.

On tax, the short answer is that it does not work the way people hope. Washington has no personal
income tax but does have sales tax, and in any case marketplace facilitator rules make Amazon
responsible for collecting based on where your buyer lives rather than where your inventory sits.
Inventory location is not a tax strategy, and I’d disregard advice suggesting otherwise.

As everywhere, Amazon assigns your inbound destination and only fulfillment centers hold seller
stock.

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 Washington state?

The complete list with codes, addresses, and types appears in the table above. King County holds more
than double any other county, centered on the Kent Valley south of Seattle.

What is UWA6?

UWA6 is recorded in our listing as a grocery and Prime Now site at 20202 84th Ave S in Kent. It is the
most searched Washington facility code, which surprises people who assume a heavily searched code must
be a large fulfillment center.

Why is the Kent Valley so important to Amazon?

Because Kent, Sumner, Auburn, and Tukwila sit on flat industrial land between Seattle and Tacoma, close
to both ports and to I-5. The valley was a warehousing district long before ecommerce, and Amazon
inherited that infrastructure.

Does Amazon serve eastern Washington from Seattle?

Largely no. Spokane sits roughly 280 miles east across the Cascades and runs its own network serving
eastern Washington, northern Idaho, and parts of Montana, because the mountain crossing makes
serving it from Seattle impractical in winter.

Are the Seattle and Tacoma ports useful for Amazon sellers?

Yes. Together they form a major west coast container gateway and are meaningfully less congested than
the southern California ports, which makes them worth pricing for Pacific Northwest distribution or
eastward rail transfer.

Does storing inventory in Washington change my sales tax position?

No. Marketplace facilitator rules make Amazon responsible for collecting sales tax based on where the
buyer lives, not where inventory sits. Inventory location is not a tax strategy in any state.
