The US Treasury's Office of Foreign Assets Control (OFAC) Specially Designated Nationals and Blocked Persons List — the United States' primary sanctions list, naming persons, companies, vessels and aircraft whose property is blocked under US sanctions authorities (IEEPA, TWEA, the Kingpin Act, Global Magnitsky, and program-specific executive orders).

What a match means: A match is a direct US sanctions hit — the named party is designated and, absent a license, US persons are generally barred from dealing with them; escalate immediately rather than clearing the alert yourself.
