Every zone is a price step
Domestic rate cards charge more at every zone break. The same 2 lb parcel costs meaningfully more to ship zone 8 than zone 2. Inventory placement is a pricing decision.
See your shipping zones.
Every carrier rate card is built on zones: how far a package travels from the warehouse it ships out of. Pick a ship-from location below to watch the map redraw, then enter your own warehouse ZIP to see how your zones compare.

Where does your warehouse ship from?
Enter your current warehouse ZIP and we'll estimate the USPS zone to every corner of the country, then set your map beside ours, one for each Argo location. If you're fulfilling out of Oakland today, this is where you see what Utah or Illinois would do to your zones, and whether it's worth the move.
Execution
Where you fulfill from is a pricing decision
Parcel rates step up with every zone. When your catalog ships from one building, geography decides your margins: the far side of the country is always your most expensive to reach and always your slowest to deliver.
Move the origin and the whole map redraws. The same order book that averages a zone 6 from one coast can average far less from the middle of the country. That's why the ship-from question is worth answering with your own numbers rather than a rule of thumb.

Share of the 886 mapped 3-digit ZIP areas rated USPS zone 5+ from each origin. This counts ZIP areas, not your orders, and a real read weights by where your customers actually are. The same distance logic drives UPS and FedEx zones too.
Zones decide what shipping costs you
Carriers don't price by miles. They price by zone, a band of distance from the origin ZIP. USPS runs zones 1 through 9; UPS and FedEx use comparable systems. Three things follow from that:
Fewer zones, faster doorsteps
Ground services generally cross about a zone a day. Orders that used to ride zones 7–8 across the country arrive days sooner when they ship from a node two zones away.
Placement is a data problem
Where your stock sits, which destinations dominate your order book, what you're paying per zone: that's an analysis, not a guess. Send us a PLD file and we'll model it, then your Partner Portal shows the zone mix every day once you're live.
One partner, multiple warehouse locations
With multiple warehouse locations, we can design a fulfillment approach that fits your operational needs, then run it as one Argo. Same portal, same team, same coverage terms, whichever building your product lives in.
- We start with your data. Send a PLD file and strategic planning models your real destinations and spend. The shipping analysis is free, with no obligation.
- You get a recommendation, not a template. Which location fits your order book, what it does to your zones, and what it's worth in postage.
- You see the zone mix live. Postage, zones, and delivery times sit in your Partner Portal, itemized by shipment.
- The footprint grows with you. As your order map changes, the fulfillment plan is a conversation we keep having, not a setting you're stuck with.

Shipping zone FAQ
What is a shipping zone?
Carriers group destinations into zones by distance from the origin ZIP code. USPS uses zones 1 (local) through 9 (farthest territories); UPS and FedEx use comparable distance-based systems. Rate cards charge more for each additional zone, so the same parcel costs more the farther it travels.
Do UPS and FedEx use the same zones as USPS?
Not identical, but structurally the same: distance bands from the origin, priced in steps. A network that cuts your USPS zones cuts your UPS and FedEx zones too, which is why this map is a good proxy no matter which carriers carrier management puts on your account.
How much does a lower zone actually save?
It depends on weight, service, and your negotiated rates. Every zone break on the rate card is a price step, and dense parcels crossing four fewer zones save the most. We'd rather show you than estimate: send us a Package Level Data (PLD) file or a recent invoice and we'll re-rate your real shipments as part of the free shipping analysis.
What is a PLD file, and how do I get one?
Package Level Data is a shipment-level export: one row per parcel, with destination, weight, service, and what you were charged. Your carrier or current 3PL can produce it, usually on request or straight from your shipping platform. It's the single most useful thing you can hand us, because it turns a zone map like this one into a real analysis of your spend. See exactly what we need. If you're not sure where to pull it, ask and we'll walk you through it.
Which of your warehouse locations would my product ship from?
That's part of the conversation, and it's what the analysis is for. We look at where your orders actually go, what you're paying today, and how your catalog moves, then recommend a fulfillment approach that fits your operational needs. The map above is the first cut at that math; your PLD file is the real one.
