Package Tracking
What package tracking is, how it works behind the scenes, and how to track with any carrier.
What Is Package Tracking?
When a package enters a carrier's system, its tracking barcode is scanned at each touchpoint: initial acceptance, sorting facilities, transfer hubs, the local delivery post office or station, out-for-delivery vehicle, and final delivery. Each scan generates a tracking event with a timestamp and location. Modern tracking systems also provide estimated delivery dates and, in some cases, real-time map views of the delivery vehicle. Tracking information is accessible through carrier websites, mobile apps, email or SMS notifications, and third-party tracking aggregators that can track packages across multiple carriers from a single interface.
Why It Matters
How Each Carrier Handles Package Tracking

Frequently Asked Questions
Every shipping label has a unique barcode. As your package moves through the carrier's network, it is scanned at each facility -- acceptance, sorting centers, transfer hubs, and the local delivery office. Each scan creates a tracking event with a timestamp and location that you can view online or through the carrier's app.
Packages are only scanned at major facilities, not continuously during transport. A long 'In Transit' status usually means the package is moving between facilities that are far apart (e.g., cross-country truck transport) and hasn't been scanned recently. If there are no updates for 5+ days, contact the carrier.
Without a tracking number, you cannot directly track a specific package. However, USPS Informed Delivery can notify you about incoming packages to your address. You can also contact the sender to request the tracking number, or check your email for shipping confirmation notifications.
If tracking says 'Delivered' but you haven't received it, check around your property (porches, side doors, mailbox, with neighbors). Sometimes packages are scanned as delivered slightly before actual delivery. Wait 24 hours, then contact the carrier to file a missing package investigation. If you have shipping insurance, you may be able to file a claim.
