This free page calls the identical live OFAC lookup used by our paid API — same source, same freshness, same fields.

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.
