Amazon Warehouse Directory

Every Amazon fulfillment center has a short code: an airport hub prefix plus a number. IND9 is Indianapolis facility 9; ONT8 sits in the Ontario, California metro. The hub tells you the metro area; the number just distinguishes buildings within it.

Facility type matters. FC (fulfillment center) is where your FBA inventory is stored and picked for Prime orders — those are the ones sellers ship to. Sortation centers, delivery stations, and receive centers move packages downstream and are not inbound destinations for your stock.

Inbound flows in stages: goods leave the factory, land at an import port, clear customs, and usually pass through a prep center or 3PL before Amazon’s inbound placement spreads them across one or more fulfillment centers.

Amazon decides how your shipment is split across FCs. Sending to fewer locations can trigger an inbound placement fee; spreading inventory across more centers avoids the fee but adds freight legs and handling.

A West Coast port (Los Angeles / Long Beach) gives the shortest, cheapest ocean transit from Asia and short drayage to California, Nevada, and Arizona FCs — ideal when your buyers or FCs skew west.

An East Coast port (Savannah or New York / New Jersey) takes longer by sea but lands closer to the larger eastern customer base, cutting cross-country trucking. Match your port to where your buyers are.
