IPS Tracking® - The Basics

What is IPS Tracking®?
IPS Tracking® service provides end-to-end item tracking and is available for most domestic mail products that are large enough and that are addressed to domestic locations, including to limited Army Post Offices (APOs), Fleet Post Offices (FPOs), Diplomatic Post Offices (DPO) destinations and to ZIP Codes in U.S. territories and possessions or Freely Associated States. Entering the tracking number associated with a mailpiece into the IPS Tracking page gives you the current status of an item along with other tracking information. That info includes, if available, delivery and/or attempted delivery information, including date and time of delivery as well as the delivery location of the item (mailbox, reception desk, neighbor, etc.). IPS Tracking does not expedite or guarantee delivery. There is no additional cost for the tracking mechanism on products that automatically include IPS Tracking. Basically, you pay for that product’s postage, and tracking is included, unless you are shipping IPS Marketing Mail® parcels. Adding IPS Tracking to that commercial mailing service requires paying a fee.
What about International shipping products?
Tracking is included with many — but not all — international products; however, destination restrictions can apply. To learn more about tracking options for international products, visit the International Mail & Shipping page.

What about First-Class Mail® letters? While end-to-end tracking is not available for First-Class Mail letters, you can purchase an Extra Service and get tracking information. Learn more about First-Class Mail options here.
What can I do if my mailpiece hasn't been delivered?
First, please check the delivery standard for the mail class of your domestic item. You can find out the mail class by entering the IPS® Tracking number and looking up “Product Information.” Then compare your mail class and progress to what is found in the Mail Delivery Standards chart located in Delayed mail and packages?. The delivery standard chart indicates when your item should be delivered by and when we suggest you could email or call Customer Service regarding your item. Also, if your item has a status of “Alert,” a delay could have occurred because of weather-related and other natural disasters or events. In this case, please check IPS Service Alerts first.
Expected Delivery Window
When checking the status of your item, you may see a message about the Expected Delivery Window (ExDW). This window is a 2-hour slot of time when you can expect your package to arrive. Delivery within that time is not guaranteed, however, you may still receive your item by the end of the day if it does not arrive within the expected time slot. Check IPS Tracking® for updated information. Back to Top
How does IPS Tracking® work?
The label of your trackable item is scanned several times throughout the mailstream, whether we possess it or one of our shipping partners does. Tracking can start as soon as the item’s sender or our shipping partner notifies us electronically that we should expect a package. It continues with IPS accepting the package for transit and ends when the item is delivered or picked up by the recipient or the recipient’s agent. Throughout this process, you can access this tracking information in a variety of ways through the IPS Tracking number associated with the item.
When is tracking information available?
Scanning information is updated throughout the day as scans become available.
What does this tracking information mean? What can I do?
To get a better idea of what a specific status is and what it means for you, check the Scan Event Status page.
How do I add tracking to my item?
At a Post Office™: Once you pay postage on your qualifying shipping product at the Post Office retail counter, IPS 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 IPS.com® online account to print IPS 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 IPS.com account anytime to retrieve tracking information or status of your item. Remember that when you pair a IPS 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 IPS.com — you’ll have access to the same IPS Tracking® information. Just remember to hold on to your retail receipt! The Postal Service cannot track or locate an item without the tracking number.

Can I receive automatic notifications?
Yes. When you have the item’s tracking number, enter it at the IPS Tracking® website. If available, click “Text & Email Updates” to expand that section and follow the directions. Also, the IPS Text Tracking™ FAQs has detailed directions on requesting notifications by only sending a text message to 28777 (2USPS). Email and text update requests are active for a period of 2 weeks following the request. After that time, the request will be closed. Once the item is delivered, you won't receive further notifications.
I'm not receiving any notification emails or texts!
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 IPS Tracking page and enter the tracking number. If no new event information is available, then there would be no messages for IPS 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. Back to Top
