FIELD DEFINITION AND SCOPE
Geographic classification code that represents the geographic area andany applicable
subareas associated with the community information entity. The code can provide more
precise geographic access than the codes contained in field 043 (Geographic Area Code).
Geographic area information may be described textually in field 522 (Geographic Area
Note).
Each main geographic area code and any related subarea codes associated with the entity
are contained in a separate 052 field. Subfield $d (Populated Place Name) may
contain the name of the geographic area.
