About OnTrac
OnTrac is a last-mile e-commerce parcel carrier serving many US delivery markets. Official tracking shows when shipment data is received, when the package enters the network and when it reaches the local delivery route.
PostIndex is an independent tracking guide. It does not transport parcels and is not affiliated with OnTrac. The button above opens the carrier’s official service, where the latest operational tracking data is displayed.
How to track a OnTrac package
Check the dispatch email, marketplace order, receipt or parcel label.
Copy every letter and digit without accidental spaces.
Open official tracking and check the newest scan and delivery step.

Common OnTrac tracking statuses
The label exists, but the first physical scan may still be pending.
The carrier has received or scanned the parcel.
The shipment is moving between facilities or countries.
An international item is under import or export review.
The parcel is on its local delivery route.
The carrier recorded delivery, collection or completed handover.
Why is OnTrac tracking not updating?
A newly generated number may not work until the first physical scan. Updates can also pause between sorting facilities, during cross-border transport, customs review, weekends or transfer to a last-mile partner.
International OnTrac tracking
Cross-border packages often involve more than one company. The same number may later work on the destination postal operator’s website. A customs or partner handover can create a temporary gap even while the shipment continues moving.
