Previously I've been told by OFAC that a "true" hit requires a 100% match (name, address, other identifying info etc.). If you have a match to name only and the address info you have does not match then you have no hit.
I've been using the above as my SOP for the past couple years and haven't had any push back on it. Additionally, I like to go straight to the SDN website and go line by line with my search criteria and print off the results. For example, complete all fields (name, address, city, country,)>search>"no results found">Print page for documentation, Remove street address>perform search again>print, Remove city>perform search again>print etc. I also lower the confidence setting for any results from 100% to 85% to account for any misspellings or translation errors.
It's a bit of work but for the amount of potential hits we have it's not that bad.
...learning as I go.
