What this does — and doesn't — check
- Covers only OFAC's SDN list (primary names, aliases, and OFAC-published digital-currency addresses) — not the separate OFAC Non-SDN Consolidated List, or EU/UK/UN sanctions lists.
- Name matching is fuzzy token-overlap matching for human review, not identity verification — a match means "resembles an SDN entry closely enough to check further," and no match does not guarantee the person or entity is unlisted.
- Wallet matching is an exact match against addresses OFAC itself has published in SDN remarks.
- Informational only, not legal or compliance advice. Always verify any hit directly at OFAC's own search tool before acting on it.
FAQ
Name screening vs. wallet screening — what's the difference?
A name check is fuzzy token-overlap matching against SDN primary names and aliases, meant for human review of a possible match. A wallet check is an exact match against the crypto addresses OFAC has itself published in SDN remarks. This tool runs both from one query; they answer different questions and neither replaces the other.
Should I use the offline CLI or the paid API?
Use ofac-screen ($5+ pay-what-you-want, local Python CLI) when you want repeat, batch, or fully offline screening with a bundled sample. Use the paid sanctions_screen API ($0.006/call) when you need live, unlimited, agent- or script-driven calls with no daily cap.
Is a match here legal advice or an official compliance certification?
No. This is an informational lookup against OFAC's own published SDN data, not legal advice, not a compliance program, and not an official OFAC determination. A possible match is a signal to investigate, not a clearance or block decision — confirm any hit at OFAC's own search tool and your organization's review process.
What if I need broader wallet coverage than one-off checks?
The OFAC Wallet Screening Kit ($29) adds offline batch wallet-list screening in Python and Node, with an optional Treasury refresh. It complements ofac-screen's name-focused workflow rather than replacing it.
Built for compliance hobbyists, independent developers, researchers, and small teams doing a first pass. Not an enterprise GRC replacement, legal/compliance approval, official government determination, or a guaranteed real-time monitor.
