Want to track a USPS package? Just enter your tracking number on the USPS website or a trusted tracking platform like Ship24 to check where your package is and when it might arrive. You’ll see updates like “In Transit,” “Out for Delivery,” or “Delivered.” Whether you're waiting on mail or a package, USPS tracking helps you stay informed every step of the way.

To check the status of your USPS shipment on Ship24:
Download the USPS Mobile App on Android or iOS, enter your tracking number, and receive status updates anytime.
Send your tracking number to 28777 (2USPS) via SMS to get real-time status updates. You can also use keywords like “AA” for all activity or “DND” for delivery notifications.
If you prefer, you can call 1-800-222-1811 and provide your tracking number to get the latest update from an automated system.
Informed Delivery is a free USPS feature that shows you what mail and packages are on the way. After signing up, you’ll see daily previews of incoming deliveries, including tracking numbers when available.

Tracking updates may pause if the package hasn't been scanned recently. This is common during transit, especially at night or during peak periods. Check again later or contact USPS if no update appears after 48 hours.
If your package hasn’t arrived after 7 business days, you can file a Missing Mail request on the USPS website. Be ready to provide the tracking number, mailing date, recipient details, and a description of the package.
For assistance, you can contact USPS Customer Service:
Enter your tracking number on the USPS website or Ship24 to check the status of your package. You’ll see updates like “In Transit,” “Out for Delivery,” or “Delivered.”
Your tracking number is printed on your receipt, confirmation email, or shipping label. If someone else shipped the item, they may have sent you the number by email or SMS.
It means the package is still moving through USPS facilities and hasn’t reached your local post office yet.
If you signed up for USPS Informed Delivery, you can still see incoming mail and some packages. Without a tracking number, there’s no way to check exact status updates.
Priority Mail usually arrives in 1–3 days, First-Class in 1–5 days, and international options range from 6 to 21 days depending on the service.
There may be a delay in scanning, especially during transit or weekends. If there’s no update for over 48 hours, contact USPS support or the shipper.
It means the package is with your local USPS carrier and is expected to be delivered that day.
If no one was available during delivery, USPS leaves a notice. You can reschedule delivery online or collect your package from the nearest post office.
