2004 Second Edition TIGER/Line(R) Files Technical Documentation Appendix D-FIPS Class Code Definitions The FIPS class code appears in Record Type C. There are four major "groups" that differentiate between populated places, other geopolitical and census units, institutional facilities, and terminated entries. Some subclasses relate an entry to a class different from its own, which is useful because a number of entries serve in more than one capacity. For example, an incorporated place also may serve as the statistical equivalent of a minor civil division. Subclasses also identify close relationships; for example, some sub-classes identify entries in different classes that are coextensive. The U.S. Census Bureau uses only a subset of the classes within each group for its needs. The FIPS class codes and definitions follow. Class B-Post Offices/Postal Zones Not Corresponding To Other Locational Entities B3 3-digit ZIP Code Tabulation Area (approximated representation of the area covered by a 3-digit ZIP Code.
