OFAC SDN Sanctions Screener — Name Matching
Screen names against OFAC SDN (Specially Designated Nationals) — the primary US sanctions list. Joins sdn.csv + alt.csv + add.csv for full names, aliases, addresses. Returns matches with similarity score, programs, type, addresses. Daily-refreshed from treasury.gov. No auth.
Screen any list of names against the OFAC SDN list — Specially Designated Nationals and Blocked Persons, the primary US sanctions list maintained by Treasury. ~13,000 entities. Joins sdn.csv + alt.csv + add.csv for full names, aliases, addresses.
Built for KYC / compliance / AML / sanctions screening workflows. No login, no API key — pulls fresh files from treasury.gov on each run.
Two modes
screen (default) — name matching
Output: one row per match per input name. Includes match score (0-100) for downstream thresholding.
dump — full list export
Output: one row per SDN entity. Use for ETL or building your own screening logic.
Inputs
| input | default | notes |
|---|---|---|

Scoring
Deterministic, no ML:
- Exact normalized name → 100
- Exact alt-name → 95
- Input is substring of name → 90
- Name is substring of input → 80
- Token overlap (Jaccard) → up to 75
Normalization: lowercase, strip punctuation, collapse whitespace.
What it doesn't do
- No EU / UN / UK / Canada / OFSI lists — OFAC SDN only. Other US lists (SSI, Entity List, MEU, ...) and EU/UN will be separate actors.
- No fuzzy / phonetic / NLP matching — deterministic scoring only.
- No "false positive flag" — that's your analyst's call.
