Extended Match Codes
The Extended Match Codes option enables the return of additional information about any changes in the house number, unit number and unit type fields. In addition, it can indicate whether there was address information that was ignored. The Extended Match Code is only returned for address-level matches (match codes that begin with A, G, H, J, Q, R, S, T or U), in which case a 3rd hex digit is appended to the match code (see Match Codes).
Note: A typical match code contains up to 4 characters: a beginning alpha character followed by
2 or 3 hex digits. The third hex digit is only populated for intersection matches or as part of the Extended Match Code.
For information about the 3rd hex digit values for:
- Intersection matches, see Definitions for 1st-3rd hex digit match code values
- Extended Match Codes, see Definitions for Extended Match Code (3rd hex digit values)
"Address information ignored" is specified when any of these conditions apply:
- The output address has content in the
AdditionalInputDatafield. - The output address has a second address line
(
AddressLine2). - The input address is a dual address (two complete addresses in the input address). For example, "4750 Walnut St. P.O Box 50".
- The input last line has extra information that is not a city, state or ZIP Code, and is ignored. For example, "Boulder, CO 80301 USA", where "USA" is ignored when matching.
The table below provides descriptions of the Extended Match Code 3rd hex digit return values.
