Address location codes detail the known qualities about the geocode. An address location code has the following characters.

1st character

Always an A indicating an address location.

2nd character   

May be one of the following

 

C

Interpolated address point location.

 

G

GeoTAX Auxiliary or Landmark Auxiliary file data location

 

I

Application infers the correct segment from the candidate records

 

P

Point-level data location

 

R

Location represents a ranged address.

 

S

Location on a street range

 

X

Location on an intersection of two streets

3rd and 4th characters

Digit indicating other qualities about the location.

The following table contains the address codes.

Code

 

Description

AGn

 

Indicates a geocode match to a GeoTAX Auxiliary or Landmark Auxiliary file where n is one of the following values:

 

n = 0

The geocode represents the center of a parcel, building or landmark.

 

n = 1

The geocode is an interpolated address along a segment.

 

n = 2

The geocode is an interpolated address along a segment, and the side of the street cannot be determined from the data provided in the auxiliary file record.

 

n = 3

The geocode is the midpoint of the street segment.

APnn

 

Indicates a point-level geocode match representing the center of a parcel or building, where nn is one of the following values:

 

nn = 02

Parcel centroid

Indicates the center of an assessor’s parcel (tract or lot) polygon. When the center of an irregularly shaped parcel falls outside of its polygon, the centroid is manually repositioned to fall inside the polygon as closely as possible to the actual center.

 

nn = 04

Address point

Represents field-collected GPS points with field-collected address data.

 

nn = 05

Structure point

Indicates a location within a building footprint polygon that is associated with the matched address.

Usually, residential addresses consist of a single building. For houses with outbuildings (detached garages, sheds, barns, etc.), the structure point will typically fall on the primary structure.

Condominiums and duplexes have multiple, individual addresses and may have multiple structure points for each building.  Multi-unit buildings are typically represented by a single structure point associated with the primary/base address, rather than discrete structure points for each unit.

Shopping malls, industrial complexes, and academic or medical center campuses are commonly represented by a single structure point associated with the primary/base address for the entire complex. When multiple addresses are assigned to multiple buildings within one complex, multiple structure points may be represented within the same complex.

 

nn = 07

Manually placed

Address points are manually placed to coincide with the midpoint of an assessor’s parcel’s street frontage at a distance from the center line.

 

nn = 08

Front door point

Represents the designated primary entrance to a building. If a building has multiple entrances and there is no designated primary entrance or the primary entrance cannot readily be determined, the primary entrance is chosen based on proximity to the main access street and availability of parking.

 

nn = 09

Driveway offset point

Represents a point located on the primary access road (most commonly a driveway) at a perpendicular distance of between 33-98 feet (10-30 meters) from the main roadway.

 

nn = 10

Street access point

Represents the primary point of access from the street network. This address point type is located where the driveway or other access road intersects the main roadway.

 

nn = 21

Base parcel point

The Centrus point data includes individual parcels that may be "stacked". These stacked parcels are individually identified by their unit or suite number, and GeoTAX is able to match to this unit number and return the correct tax jurisdictions. If an input address is for a building or complex without a unit number, the "base" parcel information returns and will not standardize to a unit number or return additional information such as tax jurisdictions.

 

nn = 22

Backfill address point

The precise parcel centroid is unknown. The address location assigned is based on two known parcel centroids.

 

nn = 23

Virtual address point

The precise parcel centroid is unknown. The address location assigned is relative to a known parcel centroid and a street segment end point.

 

nn = 24

Interpolated address point

The precise parcel centroid is unknown. The address location assigned is based on street segment end points.

AIn

 

The correct segment is inferred from the candidate records at match time.

ASn

 

House range address geocode. This is the most accurate street     interpolated geocode available.

AIn, ASn, and ACn share the same qualities for the 3rd character n as follows:

 

n = 0

Best location.

 

n = 1

Street side is unknown. The Census FIPS Block ID is assigned from the left side; however, there is no assigned offset and the point is placed directly on the street.

 

n = 2

Indicates one or both of the following:

•The address is interpolated onto a TIGER segment that did not initially contain address ranges.

•The original segment name changed to match the USPS spelling. This specifically refers to street type, predirectional, and postdirectional.

Note: Only the second case is valid for non-TIGER data because segment range interpolation is only completed for TIGER data.

 

n = 3

Both 1 and 2.

 

n = 7

Placeholder. Used when starting and ending points of segments contain the same value and shape data is not available.

ARn

 

Ranged address geocode, where n is one of the following:

 

n = 1

The geocode is placed along a single street segment, midway between the interpolated location of the first and second input house numbers in the range.

 

n = 2

The geocode is placed along a single street segment, midway between the interpolated location of the first and second input house numbers in the range, and the side of the street is unknown. The Census FIPS Block ID is assigned from the left side; however, there is no assigned offset and the point is placed directly on the street.

 

n = 4

The input range spans multiple USPS segments. The geocode is placed on the endpoint of the segment which corresponds to the first input house number, closest to the end nearest the second input house number.

 

n = 7

Placeholder. Used when the starting and ending points of the matched segment contain the same value and shape data is not available.

AXn

 

Intersection geocode, where n is one of the following:

 

n = 3

Standard single-point intersection computed from the center lines of street segments.

 

n = 8

Interpolated (divided-road) intersection geocode. Attempts to return a centroid for the intersection.
