Amazon IXD locations.

Amazon's Inbound Cross-Dock (IXD) network is small. 5 active US facilities absorb most palletized FBA freight before the boxes get broken down and shipped to downstream sortable and non-sortable fulfillment centers. Here's where they are, who should ship to them, and how they change your inbound math.

Primer

What an IXD actually does.

Where the IXD sits in the FBA inbound flow and what it changes for sellers. If you're shipping small parcel, IXDs are mostly irrelevant. If you're shipping LTL or FTL freight, your destination is almost certainly an IXD.

An IXD is Amazon's entry point for palletized seller freight. Seller ships an LTL or FTL load to an IXD. The IXD receives the pallets, breaks them down into smaller per-FC sub-shipments, and forwards each sub-shipment to the downstream sortable or non-sortable FC where the items will actually live.

The reason IXDs exist: downstream FCs aren't built for freight intake. A sortable FC is optimized for conveyor-based small-item flow; a non-sortable FC for pallet-and-forklift work, but not for high-volume freight receiving. Concentrating freight intake in a small number of IXD buildings keeps the downstream FC network running efficiently.

For sellers, the practical difference is where to ship the truck. If you import containers, the IXD address is closer to your port of entry than any FC. If you ship LTL from a domestic manufacturer, the IXD address is typically closer to that manufacturer than the nearest FC. And IXD inbound usually qualifies for the cheapest tier of Inbound Placement Service Fee (Minimal placement).

SBD1: Amazon's original IXD; the most-routed inbound cross-dock in the US. Standard destination for West Coast container freight from LA / Long Beach port.

SBD2: Secondary West Coast IXD. Heavy use during Q4. Common alternate routing when SBD1 is at capacity.

Decision framework

IXD or direct to an FC?

In most cases, sellers don't choose. Amazon's shipment-plan creation flow assigns the destination based on placement option, inbound mode, and network capacity. The seller-side levers that actually influence the assignment:

  1. Placement option (the biggest lever). Minimal placement is cheapest per unit, typically routes through an IXD, and concentrates your inbound at a single destination. Partial placement spreads across 2-3 FCs. Optimized placement spreads across many FCs and is most expensive per unit but fastest to publish-live.
  2. Inbound mode. LTL and FTL freight almost always route to an IXD if a Minimal-placement option is selected. Small-parcel inbound (UPS, FedEx) routes to sortable FCs directly, bypassing the IXD layer.
  3. Network capacity. Q4 surges push Amazon to spill across more destinations. Selecting Minimal placement during peak season may still assign multiple FC destinations if IXD capacity is full.

For a typical FBA seller using a third-party prep center, the prep center will know which IXD or FC corridor their inbound usually feeds. Ask before signing. Our verified prep centers all surface this when relevant on their profile pages. West-coast freight landing at SBD1 or SBD2 pairs with WestFBA or FBA In and Out; PNW freight via BFI3 pairs with Oregon-based McKenzie Services for tax-free intake.

FAQ

Common IXD questions.

What is an Amazon Inbound Cross-Dock (IXD)?

An IXD is an Amazon receiving facility that accepts palletized FBA inbound shipments from sellers and then breaks down the pallets into smaller shipments routed to downstream sortable and non-sortable fulfillment centers. IXDs are the entry point for larger truck-freight or container-freight inbound. Sellers using small-parcel inbound (UPS, FedEx) typically ship directly to a sortable FC; sellers using LTL or full-truckload (FTL) freight ship to an IXD.

How many Amazon IXDs are there in the US?

Amazon operates roughly 5 to 8 active IXDs in the US as of 2026, depending on which buildings Amazon classifies internally as IXDs vs. as standard cross-docks vs. as sortation centers. The major IXDs are SBD1, SBD2, FTW1, OFL1, and BFI3. The network is intentionally small compared to the ~110 US fulfillment centers because IXDs serve as funnel points for the larger inbound network.

How do I know if my FBA shipment is going to an IXD or to an FC directly?

Amazon assigns the destination when you create your inbound shipment plan in Seller Central. The destination code appears on your shipping plan: 'SBD1' or 'FTW1' = IXD; a destination starting with a major airport code followed by a numeric (LGB7, ONT2, ATL7) = a sortable or non-sortable FC. The label generation step also surfaces the destination type. If you're unsure, the shipment-creation flow in Seller Central labels each destination type.

Do IXDs change the Inbound Placement Service Fee (IPSF)?

Yes. Amazon's IPSF rates differ by placement option: the 'Minimal' option (which often routes to an IXD) is typically cheaper per unit than 'Partial' or 'Optimized' placement. For standard-size FBA inventory, Minimal placement runs roughly $0.20 to $0.45 per unit; the alternatives can run $0.50 to $1.20+. Shipping to an IXD does not guarantee Minimal-tier pricing on its own; the placement option you select in Seller Central drives the fee.

Can I ship small-parcel (UPS) directly to an IXD?

Generally no. IXDs are built to receive truck freight (LTL and FTL), not individual small parcels. If your inbound is small enough to ship UPS, Amazon will route the destination to a sortable FC instead. The IXD step exists specifically to absorb the cost and complexity of large freight inbound that downstream FCs are not designed to handle.

Should I prefer an IXD or an FC for my inbound destination?

You usually don't choose. Amazon assigns the destination based on your placement option (Minimal / Partial / Optimized), the inbound mode (small parcel / LTL / FTL), and current network capacity. The seller-controlled lever is placement option, not destination type. Choosing Minimal placement is the closest you get to forcing an IXD destination on freight inbound.

Are IXDs the same as Amazon Receive Centers (ARCs) or Sortation Centers?

No. ARCs and sortation centers are different facility types. ARCs are inbound receiving for first-mile vendor freight (typically wholesale or vendor-flex partners, not third-party sellers). Sortation centers handle outbound packages destined for delivery stations and last-mile carriers, not inbound from sellers. IXDs sit specifically in the FBA inbound flow between seller freight and downstream FCs.

What changed with Amazon's January 1, 2026 FBA Prep shutdown?

The IXD network itself is unchanged. What changed is that Amazon's in-house prep service (the FBA Prep & Item Labeling Service) stopped accepting new shipments after January 1, 2026. Sellers now prep themselves or contract a third-party prep center before the inbound shipment ever reaches an IXD or an FC. Full context on our /amazon-ended-fba-prep/ page.
