Amazon Warehouses in Colorado: Every Facility Code and Address

Colorado runs one of the more self-contained Amazon networks in the country, and it has to.
The nearest comparable metropolitan area to Denver is more than 500 miles away, so the state
cannot be served as a spoke off somewhere larger the way most states are. It carries its own
fulfillment capacity because there is no alternative.

The short version in numbers: 25 Colorado facilities on record, 23 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 Colorado 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 Colorado

25 facilities, of which 23 have a published code: 9 fulfillment centers, 6 delivery stations, 3 sortation centers, 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parcels, which is why we do not publish site phone numbers.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 Colorado codes people look up most

All four of the most-searched Colorado codes are fulfillment centers, which means a parcel showing one
has usually not been packed for you yet.

• SCO1 is at 6155 Downing St in North Washington, just north of Denver, and it draws more searches
  than any other Colorado code.
• DEN8 is in the Stafford Logistics Center at 21000 E 13th Ave in Aurora.
• UCO1 is at 480 E 55th Ave in Denver.
• DCS3 is at 5904 Dancing Sun Way in Colorado Springs.

Note that DEN8 and DCS3 both begin with letters that often signal delivery stations elsewhere, yet our
listing records both as fulfillment centers. It is a good example of why the type column beats
guessing from the prefix.

An island metro on the Front Range

Adams County holds the most facilities by a clear margin, with El Paso County and Denver level behind
it, then Arapahoe and Broomfield. By city, Aurora leads, followed by Colorado Springs and Denver.

Everything sits on the Front Range. That is the north-south strip where almost all of Colorado’s
population lives. Adams County, north and east of Denver, holds the large sites. The land there is
flat, cheap, and available. Aurora’s cluster runs along the eastern edge of the metro with easy access
to I-70. Colorado Springs operates its own smaller network roughly 70 miles south, and I’d treat it as
semi-independent rather than as a spoke.

The isolation is the whole story. Denver to Kansas City is around 600 miles. To Salt Lake City,
about 520. To Albuquerque, roughly 450. Those are not distances a truck covers overnight with time to
spare, and the consequence is that almost nothing reaching a Colorado doorstep can have been picked
that morning in another state, which forces the network to hold a broader assortment on the Front
Range than a population of five million would normally justify. Nothing else in the interior west
looks quite like it.

The flip side is that the mountains and the Western Slope are genuinely hard to serve. Grand Junction,
Durango, and the resort towns sit behind mountain passes that close in winter, and I’d expect longer
and less predictable delivery windows there regardless of season.

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.

Colorado’s genuine seller angle is the mountains

Most of what applies elsewhere applies here: you cannot choose your inbound destination, Send to
Amazon assigns it, and only fulfillment centers hold seller inventory.

The Colorado-specific point is about your customers rather than your stock. Mountain and Western
Slope addresses behave differently from Front Range ones. Delivery takes longer, winter weather
closes passes, and buyers in those areas are more likely to experience a late arrival. If a meaningful
share of your orders go to those zip codes, expect a slightly worse delivery experience there and do
not read it as a fault in your operation.

That matters because a late delivery affects your On-Time Delivery Rate whether or not a mountain pass
was the cause. Our guide to
tracking shipment performance covers which
delivery failures land on your metrics and which do not.

Altitude is worth a thought too. Sealed liquids, aerosols, and pressurized packaging behave
differently at elevation and in unpressurized freight, and in our experience that surfaces as leakage
complaints that sellers struggle to explain.

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 Colorado?

The complete list with codes, addresses, and types appears in the table above. Colorado carries a
broader local assortment than its population alone would justify, because Denver cannot be served
quickly from any other metro.

Which Colorado county has the most Amazon facilities?

Adams County, by a clear margin, with El Paso County and Denver level behind it. Adams County holds
the large sites because that is where the flat, available land north and east of Denver is.

What is SCO1 and where is it?

SCO1 is a fulfillment center at 6155 Downing St in North Washington, just north of Denver. It is the
most searched Colorado facility code, and because it stores inventory, a parcel there has usually not
been packed yet.

Why does Amazon delivery take longer in the Colorado mountains?

Because Grand Junction, Durango, and the resort towns sit behind mountain passes that can close in
winter, and all of them are served from the Front Range. Delivery windows there are longer and less
predictable year-round.

Why does Colorado need its own fulfillment centers?

Because Denver is unusually isolated. Kansas City is roughly 600 miles away, Salt Lake City around
520, and Albuquerque around 450, so nothing can be served quickly from outside the state.

Does altitude affect Amazon shipments in Colorado?

It can. Sealed liquids, aerosols, and pressurized packaging behave differently at elevation and in
unpressurized freight, which sometimes shows up as leakage complaints that sellers find hard to
explain.
