Zip Code Tabulation Areas (ZCTA) by County

Get the list of all Zip Code Tabulation Areas (ZCTA) in the United States with corresponding list of Counties (and counterparts) associated with each ZCTA, and details including: the government type of the County's Equivalent or counterpart (Borough, Census Area, City, County, District, Federal District, Municipality, Municipio, Parish, Unincorporated Territory, Unorganized Atoll), the Land Area and Water Area of both ZCTA and County, and how much Land Area and Water Area of that County is assigned to that ZCTA.

ZCTA Codes are ZIP Codes that are used by the Census Bureau to represent population blocks or tabulation areas. For tabulation blocks that contain housing units, the ZCTA Code is the ZIP Code associated with the most addresses in that block. Only populated areas are included in the Census data, and thus ZIP Codes that only serve PO Boxes have no corresponding ZCTA.

The list is sorted by State name, then County name, and then ZCTA Code.
