Address Coding Guide (ACG)
directory listing the beginning and ending house numbers and street names contained in various geographic units, such as a block group, carrier route, census tract, or ZIP code. The guide is used to segment (see list segment) and sort mailing lists and to perform cluster analyses. Although many large mailers maintain their own address coding guide, the U.S. Bureau of the Census publishes its version, listing block groups and enumeration districts.
