USPS 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 USPS 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.).

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 USPS 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 USPS Tracking number associated with the item.

Scanning information is updated throughout the day as scans become available.

Once you enter the tracking number of an item(s) into the USPS Tracking® website, you can review the latest status of that item. Depending on the status, origin and destination, and the class and services of the item, you may be able to take a number of different actions if available. You can find the item’s tracking history and see what kind of services and features are associated with it. You can request emails and/or text messages about your item or a Proof of Delivery email. You can also leave instructions for the carrier on where to leave your mailpiece if no one is available to accept it.

USPS does not have the ability to find out when a carrier or delivery person will arrive at a specific location. The volume of mail fluctuates daily; therefore, delivery times are not guaranteed. All deliveries should be made by 5:00 p.m. local time Monday through Saturday. Unusual circumstances (such as traffic, staffing fluctuations, severe weather, natural disaster, changes in carrier route, etc.) can cause deliveries to be made after this time.
