How to Find Your Average Shipping Zone From a Shopify Export
Short answer: Your average shipping zone is the order-weighted average of the carrier zones (2 to 8) between your warehouse and each customer's ZIP code. To find it, export 3 to 12 months of orders with the shipping ZIP column from Shopify, WooCommerce or Amazon, then either look each ZIP up against your carrier's zone chart or upload the file to a tool that does it for you, such as the free Atomix Order History Analyzer. The number matters because zone drives both transit time and label cost, and it is the fastest way to see whether a different warehouse location would save you money.
What is an average shipping zone?
Domestic ground carriers price by zone, a measure of distance between origin and destination. Zones run from 2 (nearby) to 8 (farthest). Your average zone is simply the zones of all your orders added up and divided by the number of orders. A brand whose average is 4 ships most orders a moderate distance; a brand averaging 6 or more is sending a large share of packages across the country. If zones are new to you, start with our explainer on what shipping zones mean.
Step 1: Export your orders
Use at least three months of orders, and a full year if you have strong seasonality. You only need one row per order with a ship-to ZIP code; names and street addresses are not needed.
How do I export orders from Shopify?
- In the Shopify admin, go to Orders and click Export.
- Choose the orders to export, for example Orders by date with a start and end date.
- Pick a CSV format and click Export orders.
According to Shopify's help center, exports of up to 50 orders download directly, while larger exports and date-range exports are emailed to you and the store owner. The file includes a Shipping Zip column, which is the field you need.
How do I export orders from WooCommerce?
WooCommerce needs an order export extension. Choose a 3 to 12 month date range, make sure the Shipping Postcode field is included, and download the file as CSV.
How do I export orders from Amazon Seller Central?
Go to Reports, open the order reports, and request a report covering 3 to 12 months. The file includes a ship-postal-code column.
If any export opens in Excel, save it back as CSV before you use it.
Step 2: Turn ZIP codes into zones
The manual way
Carriers publish zone charts keyed to your origin ZIP. Look up the zone for each destination's three-digit ZIP prefix, add a Zone column to your spreadsheet, and average it. A pivot table on that column also gives you your zone mix. This works, but it is slow to repeat for several possible warehouse locations.
The faster way
The Atomix Order History Analyzer reads the same CSV in your browser; the page states that nothing is uploaded. It accepts up to 50,000 rows, or you can paste ZIP codes directly. You choose:
- Service level: Ground or Economy
- Average package weight (used if your file has no weight column)
- Your current average shipping cost per order
- Which Atomix warehouses to compare: Milwaukee, Salt Lake City, Baltimore or any combination
- Optionally, your current ship-from ZIP for a side-by-side comparison
Step 3: Read the results
The analyzer returns five things worth looking at, in this order:
- Average zone. Your headline number, for your current origin and for each warehouse combination.
- Zone mix. A chart of how many orders fall into each zone. Two brands can share an average of 5 with very different mixes; a heavy tail in Zones 7 and 8 is where cost and delays concentrate.
- Average transit time. Estimated ground days to your customers.
- Share of orders delivered in 2 days or less. The clearest single read on whether you can promise fast delivery without paying for air.
- Shipping savings per order. Compared with the average cost you entered.
The page notes that zones are estimated from the distance between ZIP code areas and that costs use Atomix rates before carrier surcharges, so treat the result as a planning estimate and confirm with a full quote. You can export the results as CSV or PDF, and the top-10 states and customer density map show where your demand actually sits.
Worked example: calculating an average zone by hand
Here is an illustrative mix for 1,000 orders shipped from one warehouse:
| Zone | Share of orders | Zone × share |
|---|---|---|
| 2 | 10% | 0.20 |
| 3 | 15% | 0.45 |
| 4 | 20% | 0.80 |
| 5 | 20% | 1.00 |
| 6 | 15% | 0.90 |
| 7 | 10% | 0.70 |
| 8 | 10% | 0.80 |
| Average | 100% | 4.85 |
An average of 4.85 with 20% of orders in Zones 7 and 8 suggests the warehouse sits off-center from where customers live. The next question is what a second location, or a more central one, would do to that tail.
What should you do with your average zone?
- Average above about 5, with a heavy Zone 7 to 8 tail: model a second warehouse on the opposite side of the country, or a central one. Our breakdown of shipping from California to East Coast customers shows what that change looked like for one sample brand.
- Average around 4 with most orders in Zones 2 to 5: your location already fits your customers. Focus on packaging and rates; see the DIM weight chart by box size.
- Comparing 3PLs: run the same export against each provider's warehouse locations rather than trusting coverage maps. A 3PL whose network fits your customer map will usually beat one with a lower rate card.

Frequently asked questions
What is a good average shipping zone for an ecommerce brand?
There is no universal target, but lower is better for both cost and speed. Compare your current average with what the same orders would average from other locations; the difference is what matters.
How many orders do I need to calculate an average zone?
Use 3 to 12 months of orders. The Atomix Order History Analyzer accepts up to 50,000 rows per file.
Which column in a Shopify order export has the ZIP code?
The Shipping Zip column, which holds the customer's shipping ZIP or postal code.
Does the Order History Analyzer upload my customer data?
The tool page states that files are processed in your browser and nothing is uploaded. Names and addresses are ignored; it reads the ZIP column.
Is average zone the same as average transit time?
No, but they move together. Higher zones usually mean more ground days. The analyzer reports both.
