ZIPKEY is a software that facilitates accurate typing of US addresses and reduces time consumption by instantly typing city, state, and other details when you input a zipcode. Additional features include area code and time zone lookup.

ZIPKEY's primary goal is to eliminate the need for manual typing of United States city or town names (at least not one big enough to have its own zipcode). ZIPKEY allows users to instantly access any of the 42000+ zipcodes in the directory when run from their desktop. They can search by zipcode, state-and-city, city-only, or area code.
Even if the user only needs to look for a zipcode or area code occasionally, they can double-click on the ZIPKEY icon and follow the prompts. The full power of ZIPKEY is achieved when it is placed resident in memory. In this mode, the user can invoke ZIPKEY from within any other program. They can type just a 5-digit zipcode, and ZIPKEY will make the program they're running think that they have typed any or all of the following: the city name, the state name and/or abbreviation, the zipcode, the area code, the time zone, and any other combination of fixed keystrokes and/or mouse clicks.
ZIPKEY allows users to define any number of "hotkeys" to customize the feeding of ZIPKEY's data to all their applications in which they work with addresses. Its new Windows-based configuration makes it easy to set up and test hotkeys. Users can get ZIPKEY at an affordable price and enjoy the convenience and power that it offers.
