More than 1 million iPhone, iPod touch and iPad customers have downloaded the U.S. Postal Service mobile app since it launched in December 2009 (Link, 1/4/2010). The free business app has consistently been one of the top 10 in the App Store.

“We’re expanding access to our products and services,” said PMG Pat Donahoe. “We know simpler is better — a million mobile customers can’t be wrong.”

The new USPS Mobile application takes advantage of Global Positioning Satellite (GPS) capabilities, using the Locator function to show the closest Post Offices, Automated Postal Centers and collection boxes. Maps and directions to the closest location — driving, walking or mass transit — are available.

The Postal Service app also has a ZIP Code lookup, providing the ZIP Code of the user’s current location by tapping into the phone’s GPS capability.

The Track and Confirm feature offers information on the progress of mailpieces and requires 1-time entry of tracking code numbers. This means follow-ups are only one click away
