The United States Postal Service has announced the release of its own Apple app, which is available for download on iPhones and iPod Touches.
It will contain ZIP Code validation
software which allows users to verify the correct destination of their packages before they send them.
This system will utilize the Apple gadgets' GPS capabilities to show the location of an entered ZIP Code.
Robert Bernstock, president of mailing and shipping services at USPS, said: "The Postal Service is America's largest retailer, with 36,000 Post Offices and retail outlets in communities across the country. Now the iPhone community has a Post Office as well.
"We want to continue our 234-year tradition of serving every American community, whether it's in a Post Office, online or even over the phone."
USPS also announced that additional apps featuring its services are in development.
