Extended Match Codes

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).

Extended Match Code return values

"Address information ignored" is specified when any of these conditions apply:

  • 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.
