About these sources
The EU's Financial Sanctions Files (FSF) — the European Commission's consolidated feed of every person, group and entity subject to an EU asset freeze under Council CFSP decisions and their implementing Regulations (Russia/Ukraine, terrorism, WMD proliferation, and more).
What a match means: A match is an EU sanctions designation — funds and economic resources generally cannot be made available to this party under EU law; treat as a direct compliance hit.
The UK Sanctions List (UKSL), published by the Foreign, Commonwealth & Development Office — since 28 January 2026 the single, current source for all UK sanctions designations (financial, immigration, trade and transport measures), superseding the older OFSI Consolidated List.
What a match means: A match is a current, binding UK sanctions designation — treat as a direct compliance hit and escalate immediately.
The UK's former OFSI Consolidated List of Financial Sanctions Targets, maintained by HM Treasury. OFSI closed this list on 28 January 2026 — current UK sanctions designations now publish only to the FCDO UK Sanctions List (also in this catalog) — and it is retained here as a historical source.
What a match means: A match reflects a UK financial-sanctions designation recorded before the 28 Jan 2026 cutover; check whether the same party also appears on the current UK Sanctions List, and treat either appearance as a genuine UK sanctions hit, not a stale false positive.
The US Treasury's Office of Foreign Assets Control (OFAC) Specially Designated Nationals and Blocked Persons List — the United States' primary sanctions list, naming persons, companies, vessels and aircraft whose property is blocked under US sanctions authorities (IEEPA, TWEA, the Kingpin Act, Global Magnitsky, and program-specific executive orders).
What a match means: A match is a direct US sanctions hit — the named party is designated and, absent a license, US persons are generally barred from dealing with them; escalate immediately rather than clearing the alert yourself.
