At a Post Office™: Once you pay postage on your qualifying shipping product at the Post Office retail counter, USPS Tracking® is automatically activated. Use the tracking number on your mailing receipt to then access delivery information. See “How do I access tracking information?”
Online: Create an USPS.com® online account to print USPS Tracking® labels, purchase mailing/shipping services, buy stamps, etc. The tracking label prints both the label affixed to the product AND a receipt with the tracking number. Access your USPS.com account anytime to retrieve tracking information or status of your item.
Remember that when you pair a USPS Tracking® product with a compatible Extra Service, you can receive proof of delivery, such as a signature. See Domestic Extra Services and International Extra Services for details.
Whichever option you choose — at the Post Office retail counter or online at USPS.com — you’ll have access to the same USPS Tracking® information. Just remember to hold on to your retail receipt! The Postal Service cannot track or locate an item without the tracking number.
You may not receive any updates or status emails or texts if there are no new shipment updates or the email address entered was incorrect. To be certain that you are experiencing an issue, visit the USPS Tracking page and enter the tracking number. If no new event information is available, then there would be no messages for USPS to send. If there is new event information and you haven’t received it, then try submitting another notification request.
If you requested email notifications and are having problems, also try looking in your spam/junk mail folder. If enabled, the junk mail should be checked to ensure emails from the Postal Service are allowed.
