Abstract: This dataset relates ZIP codes to counties, to standard metropolitan statistical areas (SMSAs), and, in New England, to minor civil divisions (MCDs). The file covers the 50 States, the District of Columbia, Puerto Rico, the Virgin Islands, Guam, and American Somoa. The relationships between ZIP codes and other geographical units are based on 1979 boundaries, changes since that time are not reflected. The Census Bureau used various sources to determine ZIP code-county (or MCD) relationships. In the cases where the sources were confusing or contradictory as to the geographical boundaries of a ZIP code, multiple ZIP code records (each representing the territory contained in that ZIP code area) were included in the data file. As a result, the file tends to overstate the ZIP code-county (or MCD) crossovers. The file is organized by ZIP code and has 54,668 records with a logical record length of 78. Variables include ZIP codes, Post Office names, FIPS state and county codes, county or MCD names, and SMSA codes. The dataset was made available to ICPSR by DUALabs, Inc.
