Tracking mail is a simple process if the shipper used a form of shipment that includes tracking information. If your package or letter has a tracking number, use it to view the status of your shipment at any time. Tracking results show the date and time your letter was mailed, its whereabouts at any given date and time and the estimated date of delivery. If your letter is missing and has a tracking number on it, you can obtain information as to where your letter was last located and provide that information to the post office to begin searching for your missing mail.
Get the tracking number of your package or letter. Check shipment confirmation emails from the shipper or call the shipper directly to inquire about a tracking number.
Visit the United States Postal Service (USPS) website and locate the “Track and Confirm” link on the homepage and click on it.
Enter your tracking number in the box, verifying that you entered the correct number before submitting your search. View the results of your mailed letter to see where it was last located. Use this information when reporting your letter missing to the post office; the post office can use this information to begin tracking your lost mail.
