Note 2 to § 594.201: The names of persons whose property and interests in property are blocked pursuant to paragraph (a) of this section are published in the FEDERAL REGISTER and incorporated into the Office of Foreign Assets Control's SDN List with the identifier "[SDGT]." Persons who have been identified by the Office of Foreign Assets Control as officials, agents, or affiliates of the IRGC are identified by a special reference to the "IRGC" at the end of their entries on the SDN List, in addition to the reference to this part. For example, an affiliate of the IRGC whose property and interests in property are blocked pursuant to this part will have the program tags "[SDGT] [IRGC]" at the end of its entry on the SDN List. The SDN List is accessible through the following page on the Office of Foreign Assets Control's website: https://www.treasury.gov/sdn. Additional information pertaining to the SDN List can be found in appendix A to this chapter. See § 594.412 concerning entities that may not be listed on the SDN List but whose property and interests in property are nevertheless blocked pursuant to paragraph (a) of this section.
Note 3 to § 594.201: The International Emergency Economic Powers Act (50 U.S.C. 1701 - 1706 ), in Section 203 (50 U.S.C. 1702 ), authorizes the blocking of property and interests in property of a person during the pendency of an investigation. Except as described in note 4 to this section, the names of persons whose property and interests in property are blocked pending investigation pursuant to paragraph (a) of this section are published in the FEDERAL REGISTER and incorporated into the SDN List with the identifier "[BPI-PA]" or "[BPI-SDGT]."

Notice of such orders will be provided: by publication in the FEDERAL REGISTER; in writing to persons OFAC may assess to have an interest in the property; or by issuing an order or directive in writing to financial institutions or other transaction intermediaries, and requiring the recipient of the order or directive to promptly disclose it to affected persons with whom the recipient maintains direct commercial relationships.
