Match Modes
Match Mode Description
Standard This is the default mode, and generally provides the best balance of
accurate geocoding, few false matches, and high performance. This
requires a close (not necessarily exact) street name match.
Tight This uses the most strict matching rules and requires an exact street
name match. In general, this returns the fewest number of candidates in
the fastest processing time. There will be fewer non-close matches than
are returned in Standard or Relaxed mode.
Tight mode is most suitable when your input addresses are complete, well
standardized, and free of spelling errors.
L
Tight mode is not equivalent to selecting Custom matching with all
Exact Match criteria checked.
Relaxed This provides less strict matching rules. In general, Relaxed mode
increases your chances of getting a close match but performance
(geocoding speed) may not be as good.
Relaxed mode:
• allows the most variation in street name spelling, and therefore may
return desirable candidates that are not returned in other modes.
• is most suitable when your input addresses are not well standardized,
incomplete, or may contain spelling errors.
• is the only mode that does not respect street parity.
• is more likely to return false positive candidates.
• may (but does not always) return more candidates than other modes.
• generally will perform more slowly than other modes.
• is best used as a second or third geocoding pass. See Using Wide
Search with Multiple Pass Strategy on page 103 and Using a
Multiple Pass Strategy on page 120 . strategies of optimizing match
rates using multiple geocoding passes.
• is best used if you examine the Match codes and Location codes to
verify how the address was matched, what address elements were
changed to achieve the match, and the locational accuracy of the
geocode. See
Match Codes and Location Codes on page 305 .
L
Relaxed mode is not equivalent to selecting Custom matching with
all Exact Match criteria unchecked.
