Geocode US Address Summary Report

The Geocode US Address Summary Report contains information about the job, such as the settings, number of records processed, performance statistics, and the database used, as well as detailed information about the geocoding and address matching results. This report contains the following sections.

Address Matching Summary

This section shows the number of records processed and the number of matches obtained.

  • Total Records in File—The total number of records in the input file used by this job.
  • Records Processed—The number of input records minus those records that were skipped.
  • Addresses Matched—The number of addresses that were successfully standardized and validated. This count includes all the Standardized addresses listed under the Matched Address Records section plus those with match codes beginning with G (auxiliary file), T (geographic data only), and X (intersections).
  • Unmatched—The number of records that could not be validated.

Matched Address Records

This section contains information about the addresses that were successfully matched.

  • Standardized—The number of addresses that match to USPS-relevant records. These addresses have match codes beginning with A (alias), D (small town), Q (unique ZIP), S (street), and U (rare). Only these types of matches are counted as Standardized.
  • Auxiliary File—The number of records that were matched to a user-defined file. These records have a MatchCode beginning with G.
  • Intersections—The number of records that were matched to an intersection. These records have a MatchCode beginning with X.
  • Non-USPS—The number of records that were matched to non-USPS data.

Unmatched Address Records

This section lists the number of unmatched addressees and the reasons why the addresses were not matched. For information about these codes, see Match Codes.

Standardized Address Quality

This section describes the changes that Geocode US Address made to addresses in order to validate them.

  • Original address unchanged—None of the address elements were changed to obtain a match.
  • Original last line unchanged—The last line (city, state, ZIP Code) was unchanged but other elements were changed to obtain a match.
  • Corrected predirectional—The predirectional of a street name was changed to obtain a match. For example, E MAIN ST changed to W MAIN ST.
  • Corrected street name—The name of the street was changed to obtain a match. For example, MAIN ST changed to MAINE ST.
  • Corrected street suffix—The street suffix was changed to obtain a match. For example, MAIN ST changed to MAIN AVE.
  • Corrected postdirectional—The postdirectional of a street was changed to obtain a match. For example, MAIN ST NW changed to MAIN ST SW.
  • Corrected city name—The name of the city was corrected to obtain a match. For example, LOS ANGLES changed to LOS ANGELES.
  • Corrected state abbreviation—The state abbreviation was corrected to obtain a match. For example, ROCHESTER NY changed to ROCHESTER MN.
  • Corrected ZIP Code—The ZIP Code as corrected to obtain a match. For example: 1071 MAPLE LN BATAVIA IL 49423 Changed to: 1071 MAPLE LN BATAVIA IL 60510
  • Corrected ZIP + 4 add on—The four digits that appear after the "-" in a ZIP + 4 were corrected to obtain a match. For example, 60510 changed to 60510-1135.

Geocode Matching Levels

This section describes the level of accuracy for the geocodes returned by Geocode US Address.

  • Geocodes Assigned—The number of records to which Geocode US Address assigned a geocode. This is the cumulative count of the following fields:
  • Address Match—Address geocodes indicate a geocode made directly to a street network segment (or two segments, in the case of an intersection). Addresses included in this count have a value that begins with A in the LocationCode output field.
  • Auxiliary Match—The geocode was determined using the Auxiliary File. Addresses included in this count have a value that begins with AG in the LocationCode output field. For more information, see Auxiliary Match Details.
  • Point Match—The geocode was determined using a points database, which means the geocode represents the center of a building or parcel. Addresses included in this count have a value that begins with AP in the LocationCode output field. For more information, see Point Matching Details.
  • ZIP Centroids Match—The address could not be matched, so the geocode is the center of the address's ZIP Code. This is the least accurate geocode for a given address. Addresses included in this count have a value that begins with Z in the LocationCode output field. For more information, see ZIP Centroid Matching Details.

Auxiliary Match Details

This section describes the level of accuracy for the geocodes returned by Geocode US Address that were obtained from the Auxiliary File. For more information, see Auxiliary File Overview.

These fields are ordered from the most accurate type of geocode to the least.

  • Point—The geocode represents the center of a building or parcel. Addresses included in this count have a value of AG0 in the LocationCode output field.
  • Centerline—The geocode represents the location of an address along a street segment. Addresses included in this count have a value of AG1 in the LocationCode output field.
  • Centerline with unknown street side—The geocode represents the location of an address along a street segment but the side of the street where the address resides could not be determined. Addresses included in this count have a value of AG2 in the LocationCode output field.
  • Midpoint—The geocode represents the midpoint of the street segment where the address resides. Geocode US Address could not determine where on the street segment the address is located. Addresses included in this count have a value of AG3 in the LocationCode output field.

Point Matching Details

This section describes the types of point-level geocodes returned by Geocode US Address. Point-level geocodes represent the center of a parcel or building.

These points are offset at a specific distance from the street centerline near the center of the side of the parcel that fronts the street segment. Street frontage points estimate address locations more accurately than do interpolated ranges. Addresses included in this count have a value of AP07 in the LocationCode output field.
  • Front Door Point—The geocode 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. Addresses included in this count have a value of AP08 in the LocationCode output field.
  • Driveway Offset Point—The geocode 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. Addresses included in this count have a value of AP09 in the LocationCode output field.
  • Street Access Point—The geocode 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. Addresses included in this count have a value of AP10 in the LocationCode output field.
  • 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 Geocode US Address is able to match to this unit number and return the correct APN. Addresses included in this count have a value of AP21 in the LocationCode output field.
  • Backfill Address Point—The precise parcel centroid is unknown. The address location assigned is based on two known parcel centroids. Addresses included in this count have a value of AP22 in the LocationCode output field.
