SDN list
The list of Specially Designated Nationals and Blocked Persons published by the U.S. Treasury.
Updated 2026-07-26
The SDN list names individuals, companies, vessels and aircraft whose assets are blocked and with whom dealings by U.S. persons are generally prohibited. It is the most widely referenced sanctions list and the one most often reproduced by third parties.
Each entry carries a unique identifier, a primary name, a type, one or more programme codes and frequently a list of alternative names and addresses. Entries are added, amended and removed over time, and the identifier is the only stable handle across those changes.
Reproductions age quickly. A search here reports which snapshot it was run against, with its publication date, so that the answer can be checked against the authority's own current version.
