Special Report: Geocoding - Achieving the Highest Accuracy

Although geocoding is only one part of the examination accuracy testing, it is substantially different from the other submittable data that is tested. The geocode is probably the most important data element because of its demographic impact. There is no such thing as 100% accuracy for geocodes on a complete LAR due to the complexities and subtleties of the subject, but there is at least one proven solution that can achieve greater than 98% accuracy. This document contains statistical and anecdotal evidence describing how to achieve the highest precision level possible to help avoid a time-consuming resubmission process or a costly penalty. See the geocoding engine behind these accuracy figures. If you want to check a hard-to-place address yourself before it becomes a resubmission problem, the census tract and address geocoding tool runs it against several geocoders at once and plots every answer on one map.
