Congressional Districts by ZIP Code Tabulation Areas


Table Description

This table lists each ZIP Code Tabulation Area (ZCTA) 5-digit code, numerically within the state, and provides the congressional district that relates to each ZCTA. If more than one congressional district relates to a ZCTA, each district is listed, separated by a comma or a hyphen (e.g. 6-9 represents congressional districts 6, 7, 8 and 9).

Definition

ZCTAs are generalized area representations of U.S. Postal Service ZIP Code service areas. ZCTAs were created for the first time for Census 2000.

Since ZCTAs are NOT exact representations of the USPS's ZIP Code delivery areas they should not be used for mailing purposes. ZCTAs are distinct from other Census Bureau statistical areas, such as census tracts, because they are computer-delineated based on the location of addresses at the time of Census 2000 rather than manually delineated by local program participants or Census Bureau staff before the census.
