Learn how to track and interpret shipping statuses from 2,500+ carriers worldwide with our comprehensive tracking guide.
Package Tracking Basics
Package tracking is the process of monitoring the movement of your shipment from sender to recipient. Modern tracking systems provide real-time updates as packages move through various checkpoints in the delivery network.
How Package Tracking Works
When a package is shipped, it receives a unique tracking number that serves as its digital identifier throughout the delivery journey. Each time your package passes through a scanning point, its status is updated in the carrier’s system.
Package Acceptance
The carrier accepts your package and scans it into their system. This creates the first tracking record.
Transit Scans
As your package moves through sorting facilities and transportation networks, it receives multiple scans.
Delivery Scan
The final scan occurs when your package is delivered to its destination.
Benefits of Package Tracking
Visibility
Know exactly where your package is during transit
Planning
Receive estimated delivery dates to plan accordingly
Security
Verify your package reaches the correct destination
Problem Resolution
Identify issues early for faster resolution
Understanding Tracking Numbers
Tracking numbers are unique identifiers assigned to packages. Each carrier uses their own format, but all tracking numbers serve the same purpose: to uniquely identify and trace your package throughout its journey.
Common Tracking Number Formats
USPS
9400 1000 0000 0000 0000 00
20-22 digit number starting with ’94’, ’93’, or ’92’
UPS
1Z 999 AA9 99 9999 999 9
18 characters starting with ‘1Z’
FedEx
9999 9999 9999
12 or 15 digit number
DHL
999 999 999
10 or 11 digit number
Pro Tip
When a tracking number doesn’t work, check for common mistakes:
- Confusing similar characters (O and 0, I and 1)
- Including spaces or hyphens when not needed
- Entering numbers in the wrong carrier’s tracking system
- Checking too soon (allow 24-48 hours for initial tracking)
Most carriers place tracking numbers on shipping receipts, confirmation emails, and package labels. E-commerce retailers often send tracking numbers automatically once your order ships.

Expert Tracking Tips
Power users of package tracking systems employ special strategies to get the most accurate information and ensure smooth deliveries. Here are expert tips to help you track more effectively.
Check Tracking at Optimal Times
Most carriers update their tracking systems at specific times:
- USPS updates tracking in the early morning, afternoon, and evening
- UPS updates frequently throughout the day, with major updates around 9 PM
- FedEx updates tracking information after each scan, with system-wide updates around midnight
- DHL typically updates international tracking once per day
Check tracking after these update times for the most current information.
Understand Delivery Windows
Different service levels have different delivery timeframes:
- Express/Overnight: Typically delivered by 10:30 AM or 12 PM
- Ground/Standard: Usually delivered between 9 AM and 8 PM
- USPS: Mail carriers typically deliver until 5 PM, sometimes later during peak seasons
- International: Delivery windows vary greatly by country
Use Carrier Accounts for Enhanced Tracking
Create free accounts with major carriers to access additional features:

- UPS My Choice: Delivery alerts, delivery instructions, delivery window
- FedEx Delivery Manager: Customize deliveries, vacation holds
- DHL On Demand Delivery: Delivery preferences, neighbor delivery
Decode Tracking Location Information
Understanding location codes helps predict delivery timelines:
- “Regional Facility” usually means 1-2 days from delivery
- “Local Facility” often indicates delivery the next day
- Airport codes (JFK, LAX) in international tracking show air transit points
- “Sort Facility” suggests the package is being routed to the next destination
Advanced Tracking Strategies
- Cross-reference multiple tracking sources – Sometimes the carrier’s own website has more detailed information than third-party tracking sites
- Track packages on mobile apps – Carrier apps often provide real-time push notifications for status changes
- Look for delivery pattern clues – If you notice your neighborhood’s packages always arrive around certain times, you can predict future deliveries
- Use delivery instructions effectively – Most carriers allow you to provide specific delivery instructions that appear to the driver
