GLS US Tracking
GLS US tracking helps you follow a GLS parcel through pickup, regional transport, delivery windows, proof of delivery, and final delivery updates. GLS US is a regional parcel carrier in the United States — part of the international GLS Group and formerly known as GSO (Golden State Overnight) — that handles pickup, transport, and delivery itself, mainly across the western states. Use this page when a GLS package is delayed, out for delivery, delivered, or not updating.

How GLS US Tracking Works
GLS US tracking updates as a parcel moves from pickup to facility processing, regional transport, local delivery, and final delivery. The tracking page may show delivery progress, estimated delivery details, and proof-of-delivery information when available. Because GLS US runs its own pickup and delivery network, its tracking is usually more complete than a pure last-mile handoff.
Where to find your GLS US tracking number
- Shipping confirmation email
- Retailer order page
- GLS delivery notification
- Shipment receipt or label
- Marketplace order details
What GLS US Is and How Long It Takes
GLS US is a regional ground and expedited parcel carrier, popular with businesses and online stores in the western United States. Within its service area, ground delivery is often 1–3 business days, with faster priority and overnight options available. Unlike gig-style last-mile carriers, GLS US typically picks up, transports, and delivers the parcel itself — so a single tracking number usually follows the whole journey.
Common GLS US Tracking Statuses
| Status | Meaning | Next step |
|---|---|---|
| Shipment Information Received | The sender created shipping details. | Wait for GLS to receive and scan the parcel. |
| Picked Up | GLS received the package. | Check for the next facility update. |
| In Transit | The parcel moves through the GLS network. | Wait for the next scan unless the delay becomes long. |
| Out for Delivery | The local route has the package. | Check delivery instructions and watch for delivery. |
| Delivered | GLS marked the package delivered. | Check delivery location and proof of delivery. |
| Exception | A delivery problem or delay affected the shipment. | Read the latest message and contact support if needed. |
Why GLS US Tracking Is Not Updating
GLS US tracking can pause when a parcel waits for pickup, moves between facilities, enters a local delivery route, or misses a scan. A recent scan usually means the package is still moving. For the full breakdown, see our guide on GLS US tracking not updating.
