Ship anything.
Track every mile.
Every parcel gets a unique, self-verifying tracking code—twelve characters that encode its service level and origin hub, with a built-in checksum that catches a mistyped number before you waste time searching for the wrong package.
Four ways to ship.
Every shipment picks a tier when its label is created—its letter becomes part of the tracking code itself, so the code always tells you how fast it's moving.
Economical ground shipping for everyday parcels.
Faster transit for time-sensitive shipments.
Guaranteed next-day delivery, 5 PM local hub cutoff.
Cross-border shipping with customs documentation included.
Twelve characters. Zero guesswork.
A Warehouse USA tracking number is generated the instant a label is created. It isn't random—each character encodes something real about the shipment, and the final digit is a checksum that lets our system flag a mistyped code on the spot.
The check digit uses a variant of the Luhn algorithm—the same checksum method that validates credit card and ID numbers—adapted to run across letters and digits alike. Change any single character in a code and the checksum almost certainly breaks.
Built to make tracking make sense.
The Warehouse started as a class project: a case study in what it takes to build a parcel-tracking system end to end, from a tracking code that verifies itself to a clear view of a package's actual journey.
Every code is built from real information about the shipment, and checks itself for errors the moment you type it in—so a typo gets caught immediately instead of pointing you at the wrong package.
Transparency
Every code tells you something real: where it shipped from and how fast it's moving.
Speed
Labels and tracking numbers generate instantly the moment a shipment ships.
Reliability
A built-in checksum catches a mistyped tracking number before it sends you looking for the wrong package.
