The US Census options are available to match your address data to US census information. The primary function of the US Census Matcher is to assign census geographic codes (state, county, tract, block group, MCD, place code, latitude, and longitude) to address data. The US Census Matcher uses the internal output of the US Postal Matcher as input to this process.
See US Census Geocoding for details about coordinate accuracy levels. Also, see Frequently Asked Questions for answers to some of the common questions about the US Census Geocoding.
Note: The US Census directories are optional items you can purchase with the US Postal
Matcher. To purchase any of these directories, contact your account
representative.
