What Is a Shipping Tracking Number and How Does It Work?

Your package is on the move — but where is it right now? These days, customers expect visibility into their deliveries from pickup to final destination. That demand is fueling major growth in the tracking industry, which is projected to exceed $10.40 billion by 2032 with an annual growth rate of 11.9%.

Whether you’re shipping a gift to a friend or waiting on a business delivery, a shipping tracking number gives you peace of mind and lets you stay informed every step of the way.

This guide explains what a shipping tracking number is, how it works, and smarter ways to track your shipments, including real-time GPS tracking on platforms like uShip.

What Is a Shipping Tracking Number?

A shipping tracking number is a unique code assigned to your package when a shipping label is created. Think of it as your package’s fingerprint — it helps carriers scan, route, and monitor shipments through their delivery networks.

Tracking numbers allow you to:

  • Monitor your package’s progress
  • View scan history and transit stops
  • Confirm delivery
  • Report lost or delayed packages

Each carrier uses a slightly different tracking number format. Here are some examples:

Carrier Format Style Example Length
UPS 1Z + 6 characters + 10 digits 1Z999AA12345678902 18
FedEx 12–15 digits 123456789012 12–15
USPS Varies by service EA999999999US 20–22
DHL 10 digits 1234567890 10

How Do Shipping Tracking Numbers Work?

Tracking numbers work through carrier scanning technology and centralized databases. Here’s how the process works:

  1. Label Creation – A tracking number is generated when the label is printed.
  2. Scan Updates – Every time your package passes through a facility, it’s scanned and logged.
  3. Database Linking – All scans are connected to your unique tracking number.
  4. Customer View – You can enter the number online or in an app to see real-time status, estimated delivery, and any exceptions.

Most carriers share updates through websites, apps, and email notifications.
