Watchlist Lookup
How Watchlist Lookup checks a ofac lookup
Quick answer. An OFAC lookup runs a name through Sanctions List Search and reads the program code. The SDN list is blocked persons. The consolidated list holds other OFAC sanctions lists. A weak name match is a question, not a conclusion.
Program codes decide the kind of hit
OFAC publishes SDN data in CSV, XML, and PDF on the Sanctions List Service. The search tool is for one name. The files are for a program that needs the whole list. Technical questions go to the contact OFAC prints, not to a random vendor.
An OFAC name check should store the exact string, the slider setting, and every returned identifier. Clearing a false match means writing which identifier did not match.
