Is an address missing a ZIP Code? Do you know the ZIP Code, but you're not sure what city it's for? Look up your missing address information with a single click, rather than visiting USPS.com each time. PostCheck will also reformat an address to conform to the United States Post Office standards.
What's new in this version:
Added the option to not lookup +4 portion of ZIP Codes. Found that many +4 codes did not fit nicely on the iPhone, I didn't like how they looked. =) . Follow the link and
