I have about 4000 addresses, formatted for geocoding.
I created a Dual Range address locator using a line file from the county GIS. Arc autofilled all relevant fields.
I set "match without zones" to YES (I did this after troubleshooting and finding the thread from 2016 indicating that this may solve the problem.)
Geocoding still returns 0 matches.
If I build a point based address locator using the address file from the county GIS, it matches about 1800 addresses.
Where am I goofing?
Your address is missing the type of 'ST' where as your matching data (I assume your centerlines) has it. That should have hit but with a lower score than 100; maybe 80 to 85. How do you have your scores set up in the actual locator?
It would be interesting to see what is returned for the '12 Fort Athens 45701' address when using the Find tool with the "show all candidates" option checked. I've often used the Find tool to help see what candidates are returned and what the attributes are of the candidates and their scores. This can help with adjusting the Geocoding options that Joe Borgione pointed out above.
