Where does this change data come from?

OFAC's own official change-tracking feed (sanctionslistservice.ofac.treas.gov), which publishes a dated delta document naming exactly which SDN entries changed on each list action. This tool reads that feed directly — it does not compute its own diff of two snapshots.

Is this an official OFAC page?

No. This is an independent tool built on OFAC's own public, public-domain data. It is informational only, not legal advice — verify any change directly at ofac.treasury.gov/recent-actions before acting on it.

The last 30 days shown here come from a durable index refreshed periodically, plus a live top-up check of OFAC's own most-recent publication on every load, so today's action (if any) is included even between index refreshes.

OFAC Sanctions List Changes

Which OFAC SDN entries — and OFAC-published crypto wallet addresses — were added, removed, or modified in the last 30 days, sourced directly from OFAC's own official change-tracking feed. Live, free, no signup.

Source: U.S. Department of the Treasury OFAC official change-tracking feed (sanctionslistservice.ofac.treas.gov/changes/...), plus a live top-up of the most recent publication.

Free cap: 20 lookups per IP per day. Paid programmatic access removes the wall.

Work with OFAC data offline

The ofac-screen local CLI is a separate $9 suggested-price download (minimum $5) for screening names against the SDN list. It does not track list changes or screen wallet addresses.

For offline crypto wallet address checks, the OFAC Wallet Screening Kit is $29. Check the contents and final price on Gumroad. For dated changes with filters, use the paid API above.

What this does — and doesn't — track

Covers only the OFAC SDN List's own published change record — not the separate OFAC Non-SDN Consolidated List, or EU/UN/UK sanctions lists.
Every publication below is fetched from OFAC's own dated delta document (sanctionslistservice.ofac.treas.gov) — never a self-diff of two snapshots we took ourselves.
"modified" includes both substantive changes (e.g. a new alias or address on an already-listed entity) and occasional administrative corrections — OFAC's schema does not label the two differently.
Informational only, not legal or compliance advice. Always verify any change directly at OFAC's own Recent Actions page before acting on it.
