Logistics tools — local, free, no account
Each tool runs in your browser with TrackJet’s own validators; the number you type never leaves the page. Where a lookup is needed, the tool says so and hands over to the tracking page.

How these tools stay honest
- Arithmetic only: check digits are computed from the published standard (IATA for AWBs, ISO 6346 for containers, UPU S10 for postal items), nothing is guessed.
- A valid check digit means the number is well-formed, not that a shipment exists.
- Nothing is sent or stored; the pages carry no cookie.
