Before you onboard or pay a vendor, you should confirm it is not debarred, suspended, or sanctioned by the US federal government. Paying a sanctioned or excluded entity can mean clawbacks, lost reimbursement, or OFAC penalties.
| List | What it covers | Source |
|---|---|---|
| OFAC SDN & Consolidated | Sanctioned parties — payments are prohibited | U.S. Treasury |
| SAM.gov exclusions | Debarred / suspended federal contractors | GSA / SAM.gov |
| OIG-LEIE | Excluded healthcare providers & orgs | HHS-OIG |
| State debarment | State-level procurement exclusions | State agencies |
One call screens the entity against all four sources at once, deduplicates entities that appear on more than one list, and returns a clear match / possible-match / no-match verdict with the matched record, the exclusion type, the date, and a link to the primary source.
