ZCTA maps 800/899
ZCTAs or ZIP Code Tabulation Areas were produced by the U.S. Census Bureau to precisely specify the geographic regions generally served by U.S. Postal Service ZIP codes. The maps from the U.S. Census American FactFinder shade the boundaries and labels of states in gray and the 2000 3-Digit ZIP Code Tabulation Areas in blue-green. On city maps, the purple regions are the 2000 Central City of MSA/CMSA, which are the largest cities of a metro area.
If you know the first three digits of the ZIP Code of a place, these maps will give you a general idea of what region of the state the place is in. For example, given a ZIP Code of 82443, you can use your web browser find feature to look for 824. The browser then locates at least one map that contains the three-digit ZCTA.
