An OFAC sanctions check confirms whether a person or entity appears on the U.S. Treasury's Specially Designated Nationals (SDN) list or the Consolidated (non-SDN) sanctions list. U.S. persons are prohibited from transacting with sanctioned parties.
| List | What it covers | Source |
|---|---|---|
| OFAC SDN | Specially Designated Nationals & blocked persons | U.S. Treasury OFAC |
| OFAC Consolidated | Non-SDN consolidated sanctions (sectoral, etc.) | U.S. Treasury OFAC |
POST or GET an entity name (plus optional country/IDs) and the API returns whether it matches the SDN or Consolidated list, the matched record with program and remarks, and a confidence score so you can triage exact vs. fuzzy hits.
