The different types of Amazon warehouses are nine distinct facility categories, each doing one
job in a chain that runs from a manufacturer’s pallet to your doorstep. The distinction that matters
most is simple: only two of the nine ever hold seller inventory. Every other building in the
network handles parcels or freight that were picked and packed somewhere else.
That one line resolves most of the confusion people arrive with, whether they are tracking an order
or planning where to send stock. A state can hold 30 Amazon buildings and offer a seller 3 storage
options. A parcel can sit for 6 hours in an enormous facility that was never going to open it.
The nine types of Amazon warehouses at a glance
| Facility type | Holds seller inventory | What it does |
|---|---|---|
| Fulfillment center | Yes | Stores, picks, packs, and ships customer orders |
| Amazon Warehousing and Distribution | Yes | Bulk upstream storage that replenishes fulfillment centers |
| Sortation center | No | Groups packed parcels by destination region |
| Delivery station | No | Final building before the delivery van |
| Receive center | No | Takes bulk inbound freight and breaks it down |
| Air hub | No | Moves freight between regions by aircraft |
| Grocery and fresh site | No | Temperature-controlled, expiry-dated goods |
| Returns center | No | Inspects and grades returned merchandise |
| Specialty and oversize site | Yes, for qualifying goods | Furniture, appliances, and heavy bulky items |
Fulfillment centers
The buildings people picture, and the only conventional ones that store seller stock.
A fulfillment center receives inventory, stows it, picks it against customer orders, packs it, and
ships it. They are large, they are heavily automated in newer sites, and they run continuously.
The counterintuitive part is storage. Amazon deliberately does not group identical products
together. Stock is stowed into whatever location is nearby and convenient, so your units end up
scattered across a building. A picker walking a short distance for one item beats a picker walking to
a dedicated shelf of the same thing. I’ve found this is the single fact that most changes how sellers
picture the inside of a warehouse.
Fulfillment centers are also where inbound shipments are accepted or refused, which our guide to
the positions at an Amazon warehouse
covers station by station.
Sortation centers
A sortation center never opens a parcel. Everything arriving has already been picked and packed
elsewhere, and the building’s only job is grouping parcels by where they are going so they can travel
efficiently to the right region.
This is the type most often mistaken for a fulfillment center, and the confusion has real
consequences for sellers who count buildings in a state and assume they are all storage options.
Our dedicated comparison of
sortation center versus fulfillment center
covers the pair in detail, including the delivery-speed implications.
For a shopper, a sortation center scan means the parcel exists, is packed, and is moving.
Delivery stations
The last Amazon building your parcel sees.
Delivery stations receive sorted parcels, arrange them by route, and load them onto vans, including
Amazon Flex vehicles. They are smaller than fulfillment centers, far more numerous, and located close
to the populations they serve, which is why urban areas hold so many of them.
A delivery station scan is good news. In our experience it usually means delivery within a day,
occasionally two. Facility codes beginning with D are commonly delivery stations, which is the one
naming pattern that holds up reasonably well.
No seller inventory is ever stored here.
Receive centers and cross-docks
Receive centers, sometimes called inbound cross-docks or IXD sites, take very large shipments direct
from manufacturers and break them into smaller consignments for distribution across fulfillment
centers.
Nothing in a receive center belongs to a customer yet. For a seller sending container quantities,
this is frequently where the goods land first, and it is why inbound shipments occasionally show a
destination that is not where the stock ends up.
Air hubs
Air hubs move freight between regions by aircraft rather than picking any orders. Amazon’s own air
network is anchored at Cincinnati/Northern Kentucky Airport, with regional gateways elsewhere.
Air hubs explain the tracking scan that makes no geographic sense. A parcel can appear hundreds of
miles from both its origin and its destination because it is on an aircraft routing, not a truck
routing. I’d not read anything into it.
Grocery and fresh facilities
Amazon Fresh and Whole Foods sites are temperature-controlled and run on expiry dates rather than on
storage duration. The operational logic is entirely different: stock rotates in days rather than
months, and a mistake spoils rather than merely ages.
These are separate from the main FBA network, and most sellers never interact with them.
Returns centers
Where returned merchandise is inspected and graded. Sellable units rejoin inventory. Unsellable ones
are returned to the seller, liquidated, destroyed, or graded and resold, depending on settings most
sellers have never opened.
That grading decision is made quickly by a person handling hundreds of items, which is why packaging
that survives a round trip is worth real money across a year. Our guide to
Amazon Warehouse deals covers where graded
returns end up.
Specialty and oversize sites
Furniture, appliances, mattresses, and heavy bulky goods are handled in dedicated facilities with
different equipment, different handling, and a different fee structure. If your product is large, this
is the part of the network you are actually in, and the economics differ enough that it deserves its
own analysis rather than an assumption.
Amazon Warehousing and Distribution
The type most sellers have never heard of, and the second one that holds your inventory.
AWD is bulk upstream storage. You send container quantities there, and it replenishes fulfillment
centers automatically as stock depletes. For an importer bringing in large volumes, it separates the
question of where goods enter the country from the question of how much sits in fulfillment centers
at any moment. Our guide to
Amazon Warehousing and Distribution
covers whether it suits your volume.
How many warehouses does Amazon have?
The honest answer is that no exact public figure exists, and I’d be skeptical of any page that
gives one to the unit.
Amazon does not publish a live facility count. Independent trackers put the North American total in
the several hundreds across all types, and the number moves continually as buildings open, close,
convert, and get relabeled. Counts that circulate online usually disagree because they include
different facility types: a figure counting only fulfillment centers is a fraction of one that
includes delivery stations.
What you can do reliably is count a state. Our state-by-state pages list every facility on record with
its code, address, and type, which is a more useful number than a national total because it is
checkable. Distribution centers are a particular source of confusion, because Amazon does not use
that label consistently; many buildings described as distribution centers in third-party listings are
fulfillment centers, sortation centers, or partner sites.
How long a parcel spends in each type
Rough figures, and useful mainly for calibrating how worried to be:
- Fulfillment center: inventory sits for days to months; once ordered, the pick-to-ship cycle
usually takes a few hours. - Sortation center: typically under 24 hours, often 6 to 12 hours.
- Delivery station: normally under 24 hours before it goes onto a van.
- Receive center: 1 to 3 days while bulk freight is broken down.
- Air hub: hours, though a parcel can travel over 1,000 miles in that time.
- Returns center: several days, since grading is slower than picking.
I’d treat those as orders of magnitude rather than promises. Peak periods stretch all of them.
What this means if you are tracking a parcel
Read the facility type, not the name. All nine types of Amazon warehouses look similar from a
road; only the type column tells you what is happening inside.
Fulfillment center: your order probably has not been packed yet. Sortation center: it is
packed and heading toward your region. Delivery station: it is close, and usually a day out.
Air hub or receive center: it is in transit and the location tells you little.
If the tracking has stopped moving entirely, our guide to
what a carrier delay means covers how long to
wait before it is worth acting, and the answer is longer than most people want to hear.
None of these buildings accept visitors or answer questions about individual parcels. In our
experience that is the second most common thing people try, after searching the code itself.
What this means if you sell on Amazon
Two practical conclusions, and they are the whole reason this distinction matters commercially.
Only fulfillment centers and AWD sites hold your inventory. Counting Amazon buildings in your
state and concluding you have that many storage options is a misreading of the network, and it is the
most common misconception we encounter.
You do not choose which facility receives your stock. Send to Amazon assigns inbound destinations
from Amazon’s own network planning. Sellers who try to steer placement generally succeed only in
paying more, and I’d spend the effort on prep compliance instead, where the returns are real.
Our guide to shipping options for Amazon sellers
covers the decisions that genuinely are yours, and if you would rather have inbound performance and
account health monitored than discovered, that sits inside our
account management service.

FAQ
What are the different types of Amazon warehouses?
Nine types matter in practice: fulfillment centers, Amazon Warehousing and Distribution sites,
sortation centers, delivery stations, receive centers, air hubs, grocery and fresh facilities, returns
centers, and specialty or oversize sites. Only fulfillment centers and AWD sites hold seller
inventory.
What is the difference between a fulfillment center and a distribution center?
Amazon does not use distribution center as a consistent internal label, which is why the comparison
confuses people. A fulfillment center stores inventory and picks individual customer orders. Buildings
described as distribution centers in third-party listings are usually fulfillment centers, sortation
centers, or partner sites under a different name.
How many warehouses does Amazon have?
No exact public figure exists, because Amazon does not publish a live count and buildings open, close,
and convert continually. Published totals disagree mainly because they include different facility
types. Counting a single state from a verified listing is more reliable than any national number.
Which Amazon facilities store seller inventory?
Only fulfillment centers and Amazon Warehousing and Distribution sites, plus specialty facilities for
qualifying oversize goods. Sortation centers, delivery stations, receive centers, and air hubs handle
parcels or freight that were picked and packed elsewhere.
What does it mean if my parcel is at a sortation center?
It means the parcel is packed and being grouped with others heading to your region. Sortation centers
never open parcels or pick orders, so an item scanned there has already left the fulfillment stage and
is progressing normally.
Can sellers choose which Amazon warehouse receives their inventory?
No. Amazon assigns inbound destinations through Send to Amazon based on its own network planning, and
sellers cannot select a facility regardless of how conveniently it sits. Effort spent on prep
compliance returns considerably more than effort spent trying to steer placement.
Last updated: August 29, 2026. Amazon’s facility types, labels, and programs change over time, and
the company does not publish a definitive taxonomy. Seller Central carries the current inbound
requirements for your account.
