Using the Interactive Table
The interactive equivalence/look-up table below shows a row for each unique combination of a Census 2010 ZIP code area (ZCTA - ZIP Code Tabulation Area) and Census 2010 census tract. The start-up view is sorted on the State-County-Tract column (StCtyTract). View ZIP codes in one state using the State selection button. To locate a ZIP code of interest, either use the Find ZIP query or sort on the ZIP code column and then scroll down the table until the ZIP of interest is located.

There are 150,806 rows in the table, each showing a unique combination of a census tract (73,057 Census 2010 tracts) and ZIP code area (33,120 Census 2010 ZCTAs). Each row represents an intersection of the specified census tract and ZIP code area and corresponds to a geographic area of one census block or more. The total population and housing units values have been derived by summing component census block values. The sum of the population column is 308,745,538, the United States Census 2010 total population.

To view maps of ZIP code and census tract areas, in context of other geography, use the CVXE GIS with shapefiles or the Census Bureau TIGER Web Map Server. The following Phoenix/Scottsdale, AZ area view illustrates the intersection of ZCTA 85258 (orange fill pattern) with census tracts (green boundaries and geocode labels). Click Find in ZIP button below table to view only these ZIP codes and corresponding tract intersections as shown in map view. The Location 1 marker (see pointer in map) is located in the area intersecting ZIP code 85258 and census tract 2168.13 (StCtyTract=04013216813).
