OFAC Sanctions Screening - SDN list (keyless, local match)

Screen a name against the OFAC SDN list locally and keylessly - a match is a lead, not a finding.

This tool runs inside GDBS Pro. What it computes and the authorities it applies are below.

The problem

Sanctions screening against the OFAC SDN list often means paid services or live API keys, and a screen is only useful if you know exactly how fresh the list is and that a hit is a lead, not a verdict.

The local-first solution

A keyless, deterministic screen matches your query locally against a cached Treasury SDN snapshot through the GDBS server proxy, returning scored matches with the snapshot's as-of date shown prominently and no per-query call to OFAC.

What it does

Local name/entity match against the U.S. Treasury OFAC SDN list

0-to-1 match score from token overlap and substring containment, no AI

OFAC program tags (for example SDGT, IRAN, RUSSIA-EO14024) on each hit

Entry type (Individual, Entity, Vessel, Aircraft) and SDN list-entry id

Snapshot as-of date shown prominently so you know the freshness

Bindable in Worklog to screen a party automatically on matter intake

Honest scope

Keyless and local against a cached snapshot that can lag the live list, so confirm against live OFAC at the time of a decision. A match is a lead requiring human review, not a finding that a party is sanctioned, and a non-match is not a legal clearance - the SDN list is only one of several OFAC lists. No AI, no legal advice.

Authorities cited

OFAC Specially Designated Nationals (SDN) List - free public download (treasury.gov/ofac/downloads/sdn.csv). No key. The authoritative live list and the full set of OFAC sanctions lists are at sanctionssearch.ofac.treas.gov.
The server downloads the SDN CSV, caches it with a fetch timestamp, and matches the query LOCALLY (deterministic token-overlap + substring scoring). Screening never calls OFAC per query and never uses a credential.

Screen the name

Run the SDN screen in your browser and attach the dated, scored matches to a Worklog case. You supply no key, and the match runs locally rather than as a live OFAC query.
