Customers can now use their iPhone to scan barcodes on shipping labels to track packages and other mail. The new USPS mobile app stores the label numbers so customers can easily recheck the status of their shipments. The scanner function is available on iPhone 3GS, iPhone 4 and iPad 2. For added convenience, the new mobile app allows customers to access to their saved contact lists on their iPhone or iPad device.

Users can also use the new app to schedule a free next-day carrier pickup of their packages. USPS Vice President of Channel Access Kelly Sigmon said that, after scheduling a next-day pickup, customers will get an email confirmation when the request is made, when the package is picked up, and when the pickup request is modified or canceled. "Whenever and wherever they are, customers can check the delivery status of their shipments by simply scanning the barcodes on their shipping label receipts," she said.

Customers can continue to use the app to order free expedited shipping supplies and view retail and online prices. The USPS iPhone app launched in October 2009 and has been ranked as a top-10 free business application. The latest version has a new home screen with icons directing customers to available services.

More information about the new iPhone app is available on the USPS Mobile website.
