Compliance Sanctions Screen
by OFAC Sanctions Screening in Security & trust
Screen any person or company against the US Treasury OFAC sanctions lists — SDN and Consolidated, primary names plus every recorded alias, 39,000 names in total. Handles the 'LAST, First' convention OFAC uses, strips legal suffixes so Ltd and Limited match, and returns exact, strong and possible hits with the sanctions programmes attached. Tuned to over-report rather than miss. Returns the list build date so you know how current the screen is.
