ZIPKEY is a complete city-level directory of 5-digit United States zipcodes, 3-digit telephone area codes, and time zones, combined with a keyboard enhancement program. The goal of ZIPKEY is to provide enough power and flexibility so that no one with a Windows-based computer will ever again have to manually type in the name of a United States city or town (at least not one big enough to have its own zipcode).
Note: You can click on any file extension link from the list below, to view its detailed information. The list of extensions used or otherwise associated with the application may not be complete, because many common file extensions on our website, such as jpg (pictures) or txt (text files), can be opened by a large number of applications, or are too general file format. However most, if not all directly associated file extensions should be listed with its appropriate program. Although its likely, that some file extensions may be missing from the list of associated file extensions with the application, yet they can be opened, be part of, or otherwise be associated with the program.
