Where is the list of Specially Designated Nationals (SDNs) maintained?

The list of Specially Designated Nationals and Blocked Persons (SDNs) is maintained by the Office of Foreign Assets Control (OFAC). OFAC, which operates under the U.S. Department of the Treasury, is responsible for administering and enforcing economic and trade sanctions based on U.S. foreign policy and national security goals. The SDN list includes individuals, entities, and countries that are subject to sanctions due to various reasons, including involvement in terrorism, drug trafficking, and other criminal activities.

This list is crucial for financial institutions, businesses, and individuals to ensure compliance with U.S. laws and to avoid engaging in transactions that might be considered illegal. Checking the SDN list is a vital part of due diligence in preventing money laundering and other forms of financial crime. By referring to the OFAC list, entities can assess whether they are dealing with sanctioned parties, which helps mitigate legal risks and uphold the integrity of the financial system.
