USPS tracking statuses indicate the current location and processing stage of a package within the United States Postal Service logistics network. Each status appears when the package reaches a new checkpoint, such as a sorting facility, transportation hub, customs inspection center, or local delivery office.
Understanding USPS tracking updates helps customers determine whether a package is moving normally, delayed, or ready for delivery.
How USPS Tracking Works
USPS tracking works through barcode scans performed at key points in the delivery network. Each scan updates the tracking system and provides a new status.
Typical package journey stages include:
- Pre-shipment
- Package acceptance
- In-transit processing
- Local delivery preparation
- Final delivery or delivery exceptions
Stage 1: Pre-Shipment Tracking Statuses
Shipping Label Created, USPS Awaiting Item
This status appears when the sender has purchased postage and created a shipping label but has not yet given the package to USPS.
Shipment data is transmitted digitally through Electronic Data Interchange (EDI), but the package has not received a physical scan.
What this means
- The sender still has the package
- USPS has not yet received the parcel
Typical timeframe
24–48 hours before the first scan appears.
Stage 2: Package Accepted by USPS
Accepted at USPS Origin Facility
This update confirms the package has been received and scanned by USPS. The parcel may have been accepted at:
- a retail post office
- a mail processing facility
- a shipping dock or pickup location
At this point, the package officially enters the USPS distribution network.
Stage 3: In-Transit USPS Tracking Statuses
During this stage the package travels between major distribution facilities.
Arrived at USPS Regional Facility
Regional facilities are large mail processing centers where packages are sorted using automated systems. These centers are often called:
- Network Distribution Centers (NDCs)
- Sectional Center Facilities (SCFs)
Here packages are:
- unloaded from transport vehicles
- scanned and sorted
- routed to the next facility closer to the destination ZIP code
In Transit to Next Facility
This status indicates the package is currently traveling between two facilities.
Transportation methods may include:
- long-haul trucks
- cargo aircraft
- inter-facility trailers
If this update remains unchanged for several days, possible causes include:
- weather delays
- transportation schedules
- missed barcode scans
In most cases the package is still moving normally.
Stage 4: International Processing Statuses
International packages must pass through customs inspection before entering the domestic delivery network.
Processed Through Facility ISC New York
ISC stands for International Service Center. The New York ISC, located near JFK Airport, is one of the main entry points for international mail entering the United States.
When a package reaches this facility, it is transferred to U.S. Customs and Border Protection (CBP) for inspection.
Customs officers may:
- scan packages using X-ray equipment
- inspect shipments physically
- verify import regulations
- assess duties or taxes
Typical processing time
3–7 business days, though inspections may extend processing to several weeks.
Stage 5: Local Delivery Statuses
When the package reaches the destination city, USPS tracking updates begin indicating final delivery preparation.
Arrived at Post Office
This status confirms the package has reached the local post office responsible for the recipient’s ZIP code.
The package is waiting to be sorted into delivery routes.
Preparing for Delivery
Postal workers are sorting packages into route bins assigned to individual mail carriers.
At this stage the package is still inside the post office and has not yet been loaded onto the delivery vehicle.
Out for Delivery
This status indicates the package is on the delivery vehicle and scheduled to arrive that day.
During peak shipping periods the tracking system may display Expected Delivery by 9 PM, indicating deliveries may continue into the evening.
USPS Delivery Exception Statuses
Delivery exceptions occur when a package cannot be delivered as planned.
Awaiting Delivery Scan
This status appears when a package was marked “Out for Delivery” but did not receive a final delivery scan.
Possible reasons include:
- the carrier forgot to scan the package
- the delivery scan failed to transmit
- the package was returned to the post office overnight
Most packages are delivered the following day.
Delivered to Agent for Final Delivery
This status means the package was given to an authorized third party instead of being left at the door.
Examples include:
- apartment building reception desks
- mailroom staff
- parcel locker systems
- family members or roommates
Delivery Exception / Notice Left
This status means the carrier attempted delivery but could not complete it.
Common causes include:
- signature required but recipient unavailable
- locked gates or restricted access
- safety hazards such as animals
- severe weather conditions
The carrier leaves PS Form 3849 (Notice Left) explaining how to schedule redelivery or pick up the package.
Frequently Asked Questions
What time does USPS stop delivering packages?
Normal delivery hours are between 8 AM and 5 PM, though deliveries may extend to 8–9 PM during peak seasons or high package volume.
How long do packages stay at ISC New York?
Most international packages clear customs within 3–7 business days, though inspections may extend processing to 2–4 weeks.

Key Takeaway
USPS tracking statuses provide visibility into a package’s journey through the postal network. By understanding each stage—from pre-shipment to delivery exceptions—customers can determine whether a package is moving normally or requires further action.
