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 mail piece 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.).
