How to Track a USPS Package

Whether you're waiting on an online order or sending something important, knowing how to track a USPS package gives you peace of mind throughout the delivery process. USPS offers several tracking methods depending on the mail class and tools you prefer.

Finding Your USPS Tracking Number

Before you can track anything, you need your tracking number. Here's where to find it:

  • Order confirmation email: Most online retailers include a USPS tracking number when your item ships.
  • USPS receipt: If you mailed a package at the post office, the receipt contains a tracking barcode.
  • Shipping label: The tracking number is printed directly on the label affixed to the package.

USPS tracking numbers are typically 20–22 digits long and begin with numbers like 94, 93, 92, or 70, depending on the mail class.

Method 1: Track on the USPS Website

  1. Go to usps.com and click on Track a Package in the navigation menu.
  2. Enter your tracking number in the search field.
  3. Click Track to see the current status, location history, and estimated delivery date.

Method 2: Use USPS Informed Delivery

USPS Informed Delivery is a free service that lets you preview incoming mail and packages digitally. Once you register at informeddelivery.usps.com, you'll receive daily email digests showing grayscale images of letter-sized mail and tracking updates for packages — all before they arrive at your door.

Method 3: Track via Text or Email Notifications

You don't need to check the website manually. USPS lets you set up automatic notifications:

  • Go to the tracking page and enter your number.
  • Select Get Text & Email Updates.
  • Choose when you want alerts: when the package is out for delivery, delivered, or if there's an exception.

Method 4: Track by Text Message

Send your tracking number as a text message to 28777 (2USPS). USPS will respond with the latest status update for your package — no internet required.

  • Keep your tracking number saved until the package is confirmed delivered.

USPS tracking is straightforward once you know where to look. Bookmark your tracking page or set up notifications so you never have to guess when your package will arrive.
