Product description:

Organized by groups of states and counties (or statistical equivalents), this file lists the streets, address ranges on each street, and the corresponding census tract or block numbering area (BNA) codes for each address range. Also shown for the address ranges are corresponding U.S. Postal ZIP Code and 103rd Congressional District numbers, as well as Federal Information Processing Standard (FIPS) State, county, county subdivision, and place codes. The index contains only city-style addresses. P.O. boxes and other non-sequential addresses are not shown.

The ZIP Codes, as well as the FIPS place and county subdivision codes are useful in determining the correct census tract number when streets with identical names and ranges exist in different parts of the same county. Contiguous block segments that have consecutive address ranges along a street and that have the same geographic codes (State, county, census tract, ZIP, county subdivision, and place) have been collapsed together and are represented by a single record with a single address range.

Coverage:

Provides census tract/BNA information for more than 74 million individual residential addresses (collapsed into address ranges for confidentiality reasons) in 3,076 of the 3,141 counties or statistical equivalents in the United States (Puerto Rico is not included). This represents about 70 percent of all addresses in the country. Coverage within individual counties ranges from below 10 percent to better than 90 percent.
