To all USPS Mobile® app customers, we recommend downloading the updated USPS Mobile® application. This USPS Mobile® application was created to be compatible with newer Android phones. We have also fixed bugs within the app. To receive updates to your USPS Mobile® app, please download the app here.

Access popular USPS.com® tools on the go with the “USPS Mobile®” app: calculate shipping prices (limitations apply), find a Post Office ™, look up a ZIP Code™, schedule a next-day pickup, request USPS to hold your mail, access Informed Delivery® to track packages and digitally preview incoming mail, and more.

• Check the status of shipments sent using Priority Mail®, Priority Mail Express®, Certified Mail®, and certain other delivery services. Nickname your shipments and sign up for text and email alerts to notify you of the delivery status.

• Calculate a Domestic or International Price to determine how much postage you will need when you ship a letter, card, large envelope, or package (limitations apply). Choose retail or online pricing, add any extra services you need, and view the total, too.

• Find USPS® Locations when you need to get to a Post Office™, Self-Service Kiosk (APC®) or collection box with an easy-to-filter locator. The USPS Mobile app uses your device’s GPS to show your closest options on a map, along with their Regular Hours, Special Hours and Last Collection Times, and provides mapped results with driving, walking, or transit directions.

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

• Schedule a free next-day pickup and have your Letter Carrier pick up Priority Mail®, Priority Mail Express®, Global Express Guaranteed®, or Merchandise Return Services 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™ for you to pick up or be delivered by your carrier when you return.

• Scan the barcode on shipping labels with your device’s camera. The app recognizes the shipment and stores the label number, so you can stay on top of delivery status.

• Link to Informed Delivery to track packages and digitally preview your household’s incoming mail arriving soon; view grayscale images of the exterior, address side of letter-sized mailpieces.
