Specially Designated Nationals (SDN) and Blocked Persons List

Published by Office of Foreign Assets Control | Department of the Treasury | Metadata Last Checked: June 27, 2025 | Last Modified: 2016-11-01
As part of its enforcement efforts, OFAC publishes a list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them.
