Except as described in note 3 to this section, the names of persons listed in or designated pursuant to Executive Order 13553, whose property and interests in property therefore are blocked pursuant to this section, are published in the Federal Register and incorporated into the Office of Foreign Assets Control's Specially Designated Nationals and Blocked Persons List (“SDN List”) with the identifier “[IRAN-HR].” The names of persons designated pursuant to section 1 of Executive Order 13871, whose property and interests in property therefore are blocked pursuant to this section, are published in the Federal Register and incorporated into the SDN List with the identifier “[IRAN-EO13871].” The SDN List is accessible through the following page on the Office of Foreign Assets Control's website: http://www.treasury.gov/sdn. Additional information pertaining to the SDN List can be found in appendix A to this chapter. See § 562.406 concerning entities that may not be listed on the SDN List but whose property and interests in property are nevertheless blocked pursuant to this section.

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. The names of persons whose property and interests in property are blocked pending investigation pursuant to Executive Order 13553 also are published in the Federal Register and incorporated into the SDN List with the identifier “[BPI-IRAN-HR].” The names of persons whose property and interests in property are blocked pending investigation pursuant to Executive Order 13871 also are published in the Federal Register and incorporated into the SDN List with the identifier “[BPI-IRAN-EO13871].”

In certain cases, OFAC may issue an order to: identify as blocked specific property or interests in property of a person designated or otherwise blocked pursuant to this section; block specific property or interests in property of a person pending investigation; or block or impose other prohibitions with respect to specific property or interests in property less than full blocking sanctions. 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. Inquiries regarding any such order should be directed to OFAC's Compliance Division at 202-622-2490 or https://ofac.treasury.gov/contact-ofac.
