"ZIP Code Tabulation Areas (ZCTAs) are a new statistical entity developed by the U.S. Census Bureau for tabulating summary statistics from Census 2000. ZCTAs are generalized area representations of U.S. Postal Service (USPS) ZIP Code service areas. They represent either USPS five- or three-digit ZIP Code areas. ZCTAs are created based on the following criteria:
ZCTAs follow census block boundaries. The ZCTA code for each census block generally represents the majority ZIP Code of the addresses within that census block.
ZCTAs are not exact representations of the USPSs ZIP Code delivery areas.
ZCTA codes cover all land and water areas.
ZCTAs include some dedicated post office box ZIP Codes in areas served only by post office boxes.
ZCTAs representing post office box ZIP Codes generally have more than 10 addresses.
ZCTAs exclude unique, single delivery point ZIP Codes, such as those for firms and organizations.
ZCTAs are distinct from other Census Bureau statistical areas, such as census tracts, because they are not stable over time and 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.
ZCTAs are distinct from other representations of ZIP Codes because they are based on address information and ZIP Codes collected or verified during Census 2000 operations.
ZCTAs frequently cross county and place boundaries and may occasionally cross from one state into another."
