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 is new in this release:
- Fixed "US" capitalization in street names.
- Installer is now OS X 10.9 compatible.
