Look up a ZIP Code™ for any U.S. address.

Use the USPS Tracking™ tool to check the status of shipments sent using Priority Mail Express™, Certified Mail®, and certain other delivery services. You can give your shipment a nickname and save it in the app to easily keep tabs on your items.
Schedule a next-day pickup and have your Letter Carrier pick up Priority Mail®, Priority Mail Express™, Global Express Guaranteed®, or Merchandise Returns shipments from your home or office during regular mail delivery.
Request Hold Mail Service while you’re away, and we’ll keep your mail at your local Post Office™ until you return.
