Street Centroid Location Codes

Location codes that begin with "C" are street centroid location codes. Street centroid location codes indicate the Census ID accuracy and the position of the geocode on the returned street segment. Street centroids may be returned if the street centroid fallback option is enabled and an address-level geocode could not be determined.

A street centroid location code has the following characters.


1^st character	Always "`C`" indicating a location derived from a street segment.
2^nd character	Census ID accuracy based on the search area used to obtain matching Street Segment.
3^rd character	Location of geocode on the returned street segment.

The table below contains the values and descriptions for the location codes.


Character position	Code	Description
2^nd Character
	`B`	Block Group accuracy (most accurate). Based on input ZIP Code.
	`T`	Census Tract accuracy. Based on input ZIP Code.
	`C`	Unclassified Census accuracy. Normally accurate to at least the County level. Based on input ZIP Code.
	`F`	Unknown Census accuracy. Based on Finance area.
	`P`	Unknown Census accuracy. Based on input City.
3^rd Character
	`C`	Segment Centroid.
	`L`	Segment low-range end point.
	`H`	Segment high-range end point.
