I am using the Geocoding Tool in ArcMap in 10.3 to process files of 200,000 to 300,000 records at a time. Sometimes the geocoding tool returns all the records in the input file with a few unmatched records (Status=U) and other times the results have fewer records than the input file and there are no records with Status=U. Why?
Is there a way to request the system to return all records every time, even if some have Status=U?
It should return everything with either a M, T or U. Your resulting feature class will have as many points in it as matched (and/or tied depending if you count ties as matched) but you will have an attribute table that shows all that you tried to geocode.
Not sure why you'd get different results though.
