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