NOAA US County and Zone Codes
It's often useful when working with NOAA information to know your County and Zone code numbers. The following maps will help you locate your zone.

The file for download on this page is an ASCII dump in pipe ("|") delimited form, of a master shapefile maintained by AWIPS GIS Map Group (AGMG) for the maintenance of County, Public Forecast Zones, CWA boundaries, and Time zones. Each record represents a single polygon within the master file. Multiple polygons may exist for the same zone/county that contain the same attributes, but the lat and lon fields will be different as they are the centroid of the polygon. No attempt has been made to remove these seemingly duplicate entries from this text file. In addition, the coastal and offshore marine zone shapefiles are also dumped to this file.
