Brands running US fulfillment through AMZ Prep
What makes AMZ Prep's US fulfillment center network different
Most 3PLs operate from one or two locations and call it nationwide coverage. That works until a customer in Miami orders from a warehouse in Seattle and waits days for ground shipping. AMZ Prep's 50+ facilities are positioned so there's a warehouse within real ground range no matter where a customer lives, that's the difference between a 3PL with a warehouse and a 3PL with a network.
Strategic inventory placement
Split inventory across West, Central, and East zones. Orders route from the nearest facility, cutting transit time and shipping cost at the same time.
Single dashboard, every location
One WMS manages inventory across every US warehouse. Real-time visibility into stock levels, order status, and shipping performance from one login, no switching systems.
Zero placement fees
Unlike Amazon FBA, AMZ Prep never charges placement fees for distributing inventory across multiple locations. Ship to one facility and the network handles the rest.
Prep Parcel multi-carrier shipping
35+ carriers rated at the label print step. Every order routes through a cost-effective carrier that still meets the delivery promise.
What breaks when a 3PL calls one warehouse "nationwide coverage"
Most of these failure modes trace back to the same root cause: a single-location 3PL marketing itself as a national network without the actual ground-shipping footprint to back it up.
One warehouse gets marketed as a nationwide network
A single facility on either coast means the opposite coast is always 5 to 6 days out by ground, no matter what the sales page promises.
AMZ Prep: 50+ facilities across 23 states, real regional coverage →Zone distance gets blamed on the carrier
A slow delivery estimate usually isn't a carrier problem, it's a warehouse-placement problem. The right carrier still can't beat physics from a single facility 3,000 miles away.
AMZ Prep: strategic inventory splitting shortens the zone, not just the carrier →Multi-location distribution triggers placement fees
Amazon FBA charges to spread inventory across its own network. Brands assume every multi-location setup works the same way.
AMZ Prep: zero placement fees for distributing across any location →Every warehouse runs its own system
A 3PL with multiple facilities but no unified WMS means checking stock levels location by location, and reconciling numbers manually.
AMZ Prep: one dashboard, real-time visibility across every warehouse →A single-carrier warehouse pays list rates
Without a wide carrier mix rated at the label print step, every package ships at whatever rate the one contracted carrier offers that lane.
AMZ Prep: 35+ carriers, zone-skipping, cost-effective routing →Growth means renegotiating the whole setup
Scaling past what one warehouse can handle often means switching 3PLs entirely, migrating inventory, and rebuilding integrations from scratch.

US fulfillment regions where AMZ Prep operates
Owned facilities cover West Coast, Central, and East Coast, with regional hubs in Los Angeles, Chicago, Dallas, and Newark. Southeast coverage runs through AMZ Prep's network partners rather than a dedicated owned facility, worth knowing if same-day cutoff timing at a specific Southeast location matters to your operation.
West Coast
US delivery speed by zone
Ground shipping transit times from each AMZ Prep regional hub. A single warehouse in New Jersey means 5 to 6 day ground shipping to California; splitting inventory between regions turns that into a 1 to 3 day delivery for most US customers.
| Destination Zone | From West Coast | From Central | From East Coast |
|---|---|---|---|
| California, OR, WA | 1 day | 3 to 4 days | 5 to 6 days |
| TX, OK, LA, AR | 3 to 4 days | 1 to 2 days | 3 to 4 days |
| IL, IN, OH, MI | 4 to 5 days | 1 day | 2 to 3 days |
| NY, NJ, PA, CT | 5 to 6 days | 2 to 3 days | 1 day |
