Send your shipment to one fulfillment center
Short answer
By default, Amazon spreads your inventory across multiple fulfillment centers. If you'd rather ship to just one, enroll in Amazon's Inventory Placement Service: you send everything to a single assigned center, and Amazon redistributes it internally afterward. It carries a program fee and does not guarantee a single destination in every case.
The two placement options
Distributed Inventory Placement (the default). When you create a shipping plan, Amazon may assign units of a single product (ASIN) to several fulfillment centers. This can mean multiple delivery destinations for one shipment (see Multiple FBA locations in one shipment).
Inventory Placement Service (opt-in). Amazon assigns all units of a single product/ASIN to one fulfillment center. You deliver to that one center, and Amazon splits and forwards the inventory to other centers itself after it arrives. This simplifies your freight to a single destination.
What it does and doesn't guarantee
Can you pick which fulfillment center? No. Amazon decides which center your product is assigned to.
Does it guarantee your shipment won't be split across centers? No. With one shipment plan that contains multiple products/ASINs, cargo can still route to several centers. And different unit types — for example standard-size versus oversize — can be directed to different centers even under this service.
So Inventory Placement Service reduces destinations for a single-product shipment, but it isn't an absolute guarantee of one delivery point when your plan is mixed.
When it's worth it
Consolidating to one center can cut final-mile cost and coordination — fewer appointments, fewer trucks — which often outweighs the program fee for a single-product import. For current program fees and eligibility, check Amazon's Help Center.
How this works at Prime Freight
Whichever placement option you choose, tell your operations team when you book. If your plan still ends up split across centers, we handle the multiple FBA shipment IDs and delivery destinations for you (see Multiple FBA locations in one shipment). If you don't want everything delivered to Amazon at once, we can also hold cargo in storage (see Amazon storage options).
