Matched Types

Exact
The input data exactly matched a feature in the reference data source:
input 3620 S Vermont Ave, Los Angeles, CA 90089-0255
reference 3620 S Vermont Ave, Los Angeles, CA 90089-0255
Relaxed
One or more of the input data attributes had to be removed to find a match in the reference data source:
input 3620 Vermont Ave, Los Angeles, CA 90089-0255
reference 3620 S Vermont Ave, Los Angeles, CA 90089-0255

- South is missing from input and is present in the reference
For more details, see the section on Address Relaxation above.

Soundex
One or more of the input data attributes had to be matched with soundex to find a match in the reference data source:
input 3620 S Vermonnt Ave, Los Angeles, CA 90089-0255
reference 3620 S Vermont Ave, Los Angeles, CA 90089-0255
