ZIP Code Tabulation Area Maps
ZIP Code Tabulation Areas (ZCTAs) are the Census Bureau's generalized representations of U.S. Postal Service ZIP Codes, created by aggregating census blocks. STATS Indiana provides maps of Indiana by region, congressional district or statewide.
Note: Unless otherwise noted, our outputs are based on TIGER/Line 2006 data; however, bear in mind that these files only include ZIP codes current as of October 2002. The Census Bureau does not plan to update their files to more current ZIP code boundaries until Census 2010 data are released.

Note about ZCTAs ending with XX or HH
The three-digit ZCTA code and an "XX" suffix are applied to a large land area (generally larger than 25 square miles) where we had insufficient information to determine the five-digit codes. The USPS may not provide five-digit ZIP Code delivery service in this area. These are generally rural areas with little settlement; for example, parks, forest lands, and desert and mountainous areas. Smaller areas were generally absorbed into adjacent five-digit ZCTAs, but for larger areas, we did not want to overextend the surrounding five-digit ZCTAs.
The requirements for ZCTA delineation state that all census blocks receive a ZCTA code. Because large water features may border many five-digit ZCTAs, it would be difficult to divide up the water features and assign the parts to the five-digit ZCTAs on the land. Furthermore, any attempt to add these water features to land-based ZCTAs, would greatly distort the size and shape of the land ZCTAs, particularly in coastal areas. To avoid these problems, such water features receive ZCTA codes ending in "HH" (special code for hydrographic features).
