How to choose a 3PL location: what one ground day is worth.

Put the 3PL where your customers are. Searching for a 3PL near me gets you a list of warehouses near your desk, and your desk never receives a parcel. The carrier prices and times every ground parcel on the distance from the warehouse ZIP to the customer's ZIP, so each zone you cut from the typical order is cheaper postage and a shorter promise. From one warehouse in Elmwood Park, New Jersey, ground reaches the Northeast in one to two business days and the far coast in about five, and that covers most brands until the West Coast share of orders gets big enough to pay for a second building.

Should the 3PL be near you or near your customers?

Type 3PL near me into a search box and you get warehouses sorted by distance from you. Open your store's orders instead and sort the ship-to ZIP codes by count, because that's the map that decides what a carrier charges and what day the tracking page says delivered. If you run the brand from Austin and most of your orders go to New York, Boston and Philadelphia, the warehouse belongs in the Northeast, and the fact that you can't drive to it on a Tuesday afternoon will cost you less than two extra ground days on every order.

There are real reasons to want the building close to you. You can walk it before you sign, drop a rush carton at the dock yourself, and stand beside the pick line on a launch day. Then weigh those against the ZIP codes. For most brands the answer is a building in the region where most orders go that you can still reach in a morning, and if you're on the East Coast that's often the same place.

How ground zones work, and why one day counts twice

A zone is the carrier's distance band between the ZIP code a parcel leaves from and the ZIP code it goes to. USPS spells its zones out in the Domestic Mail Manual: zone 1 is the same 3-digit ZIP area or any pair of areas whose centers sit up to 50 miles apart, zone 2 reaches out to about 150 miles, zone 3 to about 300 miles, zone 4 to about 600 miles, zone 5 to about 1,000 miles, zone 6 to about 1,400 miles, zone 7 to about 1,800 miles, and zone 8 is everything beyond that (DMM 608 section 9, as of October 2026). The distance is measured between the centers of the two 3-digit ZIP areas, which is why the USPS zone chart asks for a ZIP pair and says the first three digits of the destination ZIP decide the zone (checked October 2026).

The zone does two things to the same parcel. It sets the price, because USPS prices Ground Advantage on weight and zone, meaning distance, and, as USPS puts it, the farther it travels the more you pay in postage, both checked October 2026. It also sets the clock on the parcel. FedEx says Ground delivers to every address in the 48 contiguous states within 1 to 5 business days based on the distance to the destination, and USPS says Ground Advantage arrives in 2 to 5 days, as of October 2026. Move the warehouse a zone closer to the typical customer and every parcel gets cheaper to send, and a good share of them arrive a day sooner.

That one day is worth more than it looks. On the promise side, it's the difference between telling a customer in Boston two days and telling them three, and between keeping that promise on ground or paying for air to keep it. On the cost side, the zone is on every parcel you ship, every day, for as long as the warehouse sits where it sits. You can renegotiate a storage rate next year, but you can't move a building's ZIP code.

When one East Coast warehouse covers the country, and when a second one out west pays

No single building is the same distance from everyone. From Elmwood Park, ground reaches New York, New Jersey, Pennsylvania, New England and the DC area in one to two business days and the far coast in about five. One East Coast warehouse gives the Northeast a one to two day promise and the rest of the country a five day promise, and you keep one inventory pool, one receiving dock, one safety stock and one dashboard.

A second warehouse splits all of that. You hold two safety stocks of every SKU, receive every inbound twice, and route orders by region, and when the West building runs out of a size, the order ships from the East anyway and the customer gets the five day parcel you built the second warehouse to avoid. It pays when enough orders go to the far zones that the postage you'd save on each of them beats the cost of carrying the second inventory and paying for a second set of receiving hours. Do that arithmetic on your own invoices: take the parcels that went to the far West last quarter, look up what each would have cost from a West Coast ZIP on your carrier's rate chart, and multiply the difference by the count. If that total is smaller than a second building's fixed costs plus the stock you'd tie up there, one warehouse wins.

Say 10 percent of your orders go to the Pacific states. Those parcels take about five days by ground from New Jersey, and a second building out west would make them faster and cheaper, but you'd be running two inventories for the sake of one order in ten. Say it's 40 percent and the product is heavy, and the arithmetic flips. The share, the weight and the promise on your site decide it, so run the numbers on your own ZIP codes before you take anyone's rule of thumb, including ours.

Where the port and the freight come in

Outbound happens every day of the year. Inbound happens a few times a year, and that's about the weight to give it. If your goods arrive by container, the leg that depends on the warehouse is drayage, the truck that pulls the container from the port to the dock, and it's priced per container, so it's spread across every unit inside. A warehouse an hour from the port you use beats one across the country from it, but by one truck leg per container, while the outbound zones are on every parcel.

So ask two questions. Which coast do your containers land on, and where does your domestic supplier ship from? If your factory is overseas and your forwarder routes to an East Coast port, an East Coast warehouse means the container goes from the terminal to the dock on one truck. If it lands on the West Coast and the warehouse is in the East, that container rides a train or a truck across the country before anyone can sell a unit, and you pay for that on every restock. A domestic supplier is simpler, since a pallet shipment by LTL, less than a truckload, costs more and takes longer the farther it goes. How to send inventory to a 3PL covers the inbound itself, from the SKU list to the pallet build.

The case for being close enough to visit

Distance from you still counts, just less than distance from your customers. Go and stand in the building before you sign. Watch receiving, walk the pick line, look at how returns are graded, and find a pallet of somebody else's stock to see how it's labeled. You'll learn more in an hour on the dock than in a month of calls. After that, a visit a quarter is plenty. If the ZIP codes point to a warehouse far from you, put the visits into the cost and don't let the travel talk you out of the right location. Questions to ask a 3PL has the list to bring with you.

How to compare locations on your own order data

This takes an export, a zone chart and an afternoon. Here's how we'd run it.

1. 01Export the last twelve months of orders from your store with the ship-to ZIP code, the order date and the parcel weight if you have it. A full year catches the holiday shape, and three months will do if that's all you have.
2. 02Keep the first three digits of each ZIP code. That's the unit USPS uses to define a zone, and it's enough to see the shape of your map.
3. 03Write down the ZIP code of every warehouse you're considering, including the one you ship from today.
4. 04For each candidate, look up the zone for every ZIP pair in the USPS zone chart, or ask the 3PL for the carrier's zone chart from its building and apply it the same way. A lookup on the 3-digit prefix in a spreadsheet does a year of orders in minutes.
5. 05Bucket the orders by zone and count them. Run it again weighted by parcel weight if your products are heavy, because zone and weight set the price together.
6. 06Read the two ends. The share of orders in the low zones is the part of your map you can promise fast and send cheaply from that building, and the share in zones 7 and 8 is the part that waits. The zone chart gives you distance; for days, ask each 3PL for the carrier's ground transit map from its ZIP. FedEx publishes one by origin ZIP, checked October 2026.
7. 07Add the inbound leg: which port or supplier your stock comes from, and roughly what a container or a pallet costs to reach each candidate. Then add what the visits will cost you. If the ZIP codes point one way and the inbound points the other, the ZIP codes usually win, because they're on every parcel.
8. 08Send the same export to each 3PL you're talking to and ask them to show you the zone split from their building. A 3PL that can't run that for you in a day is telling you something about its systems.

And before you sign on a location, run through this.

• Most of my ship-to ZIP codes, counted and weighted, sit in the low zones from this building.
• I've seen the carrier's ground transit map from this building's ZIP, and the delivery promise on my site matches it.
• I know which port or supplier my stock comes from and what the inbound leg to this building costs per container or per pallet.
• I can reach the building in a morning, or I've priced the visits and I'm fine with them.
• I know the West Coast share at which a second building would start to pay, because I've done the arithmetic on my invoices.
• Cross-border orders have a plan for duties and taxes, so a parcel to Toronto doesn't arrive with a bill at the door.

What shipping from Elmwood Park looks like at YNK

Our warehouse is in Elmwood Park, New Jersey, about 15 miles from Manhattan. Orders in by noon Eastern ship the same business day, and anything later goes out the next business day, or within two to three business days during peak. Every major carrier picks up here daily. By ground, New York, New Jersey, Pennsylvania, New England and the DC area are one to two business days away, and the rest of the country is about five coast to coast, with expedited services when your customer has paid for speed. Canada, the UK and the GCC ship cross-border through Passport DDP, so duties and taxes are calculated and collected at your checkout and the parcel clears customs without a bill at the door. The building, with directions, is on the New Jersey warehouse page, and the full picture is on the 3PL page.

On the inbound side we book freight for you, domestic and cross-border, and the container or the pallets come to 465 Mola Blvd, Dock 10, Elmwood Park, NJ 07407. If you're in New York City, Long Island or North Jersey, come and see receiving, the pick lines and your own pallets by appointment, Monday to Friday, 9am to 6pm ET. It's the same building that ships Veiled's six-piece orders at a 99.995% order success rate and took Nominal's 10,000+ order weekend within SLA. And if most of your customers are out west, say so in the intake; it takes about ten minutes, and we'll tell you whether New Jersey makes sense for you before you commit any inventory.
