Understanding Result Codes
As an output option, MapMarker returns a georesult code for every record it attempts to match. The
code indicates the success or failure of the geocoding operation and conveys information about the
quality of the match. Each character of the code indicates the level of precision of each address
component matched.
The result codes are written to a result column specified in the Select Output Columns dialog at the
beginning of the geocoding process. You can either create this column before geocoding or have
MapMarker create it automatically (default name Georesult) when you open your table.
The result code is an alphanumeric code of 1–10 characters. The codes fall into the following
categories:
• Single unique match
• Best match from multiple candidates
• ZIP Code centroid match
• Geographic match
• Non-match
The match precision depends on the match settings that you choose. See Match Settings and
Strategies in Chapter 5 on page 117 . Match precision also depends on the quality of the input
address data and on the quality of the Address or User Dictionary.
Each category is explained in the following topics.
Single Match (S category) on page 128
Best Match From Multiple Candidates (M category) on page 131
Postal Centroid Matches (Z category) on page 132
Geographic Matches (G category) on page 132
Non-match Codes (N category) on page 133
