Find the USPS shipping zone between any two ZIP codes, and see how zones fan out across the country from your origin.
Enter a destination ZIP, or click anywhere on the map.
Zone 1 · Closest
Zone 8 · Farthest
Zones come from the official USPS domestic zone chart for your origin ZIP prefix. Map shading is county-level for readability, so a county may border more than one zone. Zone 9 (US territories and some military addresses) is not shown.
Zones set your baseline cost, but the carrier and service you pick decide the rest. flipfox imports every eBay order, shops USPS and UPS for the lowest rate, and prints the label in one click, so a far-off Zone 8 buyer never eats your margin.
Every order is priced on USPS and UPS at discounted commercial rates, so the lower label always wins. No carrier accounts to set up.
Orders import on their own and tracking uploads the moment you print. Addresses are validated before the label prints.
Your boxes, from-address, and options are already filled in, so a label is one click away, straight to your printer.
Connect your eBay store and print your first label in minutes.
