This is a database of United States ZIP code information. It
contains a single database built from two separate sources:
the 1990 Census ZIP code information and the 2000 Census
ZCTA (ZIP Code Tabulation Area) information. These
two pieces of information together provide a nice picture
of an area.
The 1990 ZIP Code Information provides:
* The name of location for each ZIP code (normally a city)
* The other ZIP codes corresponding to the same location.
The 2000 ZCTA information provides:
* Total population and housing unit count in a given ZIP code
* Total land and water area for the ZIP code
* The state in which the ZIP code is located
* The latitude and longitude of the ZIP code
