A sanctions list is an official register of individuals, companies, organizations, vessels and aircraft that are subject to economic sanctions, such as asset freezes, bans on providing funds or services, or travel bans. Lists are published by governments and international bodies, chiefly to carry out foreign policy and national security goals and to fight terrorism, weapons proliferation and serious crime. Banks, payment firms, exchanges and many other businesses check their customers and transactions against them every day.
The best-known lists are the US Specially Designated Nationals list kept by OFAC, the UN Security Council Consolidated List, the EU's consolidated list of financial sanctions, and the UK Sanctions List. A sanctions list is not the same as a watchlist in the wider sense: lists of politically exposed persons or adverse media signal risk, while a sanctions listing creates a legal prohibition.
Sanctions list in plain terms
A sanctions list works like the list of banned customers kept behind the counter at a shop, except that it is drawn up by the government and the law, not the shop owner, says who is on it. Every business covered by the rules must check the list before serving someone, and if a name matches, it must refuse the business and often lock away any money it holds for that person.
The list is updated often, sometimes several times a week, as governments add new names or remove old ones. So the check is not a one-off at sign-up. Firms re-run it whenever the list changes and every time money moves, because a customer who was fine yesterday may be listed today.
Main sanctions lists
- United States. OFAC publishes the SDN list, which includes groups such as specially designated global terrorists, and a separate Consolidated Sanctions List of non-SDN programs with narrower restrictions. US persons must block the property of SDNs and may not deal with them.
- United Nations. The Security Council Consolidated List gathers people and entities designated by the Council's sanctions committees, such as those covering ISIL (Da'esh) and Al-Qaida, the Taliban and North Korea. UN member states must apply these measures through national law.
- European Union. The EU publishes a consolidated list of persons, groups and entities subject to its financial sanctions, adopted by the Council of the EU and binding in every member state.
- United Kingdom. Since 28 January 2026, the UK Sanctions List published by the Foreign, Commonwealth and Development Office is the single source of UK designations; HM Treasury's OFSI Consolidated List was closed on that date.
Other countries, including Canada, Australia, Switzerland and Japan, maintain their own lists, and many national authorities add domestic terrorist designations. The Financial Action Task Force requires countries to implement UN targeted financial sanctions on terrorist financing and proliferation without delay.
What an entry contains
A typical entry gives the listed name, known aliases and spelling variants, date and place of birth for individuals, nationality, passport or national identity numbers, addresses, company registration numbers or vessel identifiers, the sanctions program or legal basis, and the date of listing. The quality of these identifiers decides how easily a firm can tell a real match from a namesake.
Lists do not show everyone who is sanctioned. Under OFAC's 50 percent rule, an entity owned 50 percent or more, directly or indirectly, by one or more blocked persons is itself blocked even if it is not named. The EU and UK apply ownership-and-control tests to unlisted entities as well. Firms therefore need beneficial ownership information, not just a name check, and must watch for sanctions evasion through front companies and intermediaries.
How firms use sanctions lists
Sanctions screening compares customer names at onboarding, and again whenever a list changes, and checks the parties to each payment before it is released. Matching software allows for spelling variants and transliteration, which produces many false positives that analysts must clear using secondary identifiers. Screening sits alongside customer due diligence and transaction monitoring in a firm's controls, under the oversight of its AML compliance officer or sanctions officer.
When a true match is found, US persons must block or reject the transaction as the program requires and report blocked property to OFAC within 10 business days. Other jurisdictions have equivalent freezing and reporting duties. Remittance providers screen both the sender at collection and the recipient before payout.
Listing, delisting and limitations
Designations are made by executive or council decision, often with brief public reasons. Listed persons can ask to be removed through national procedures, or for UN listings through the Office of the Ombudsperson (for the ISIL and Al-Qaida list) or the Focal Point for delisting. Critics point to limited due process, the costs of over-cautious screening, which contributes to de-risking of whole sectors and countries, and the growing reach of secondary sanctions that target non-US firms dealing with sanctioned parties. Differences between lists also mean a firm operating in several countries must screen against each one that applies to it.
