The second segment of the EL code specifies how address component fields have contributed to deriving the geocode. The status for each field consists of a single character component label followed by a numeric value.
The component labels are:
P - premise / house number
S - street
T - city
R - region / state
Z - postcode / zip code
C - country
The numeric values are:
0 - the field was not used in deriving the geocode
4 - the field was exactly matched in deriving the geocode
7 - a partial match was made to the field when deriving the geocode
Note: The other numeric values are not used.
