The Office of Foreign Assets Control (OFAC) SDN list is a key tool in the global effort to protect the financial system from terrorist financing, money laundering and other illegal activities. The list includes individuals, companies and organizations that have been sanctioned by the U.S. Treasury Department for serious offenses. By proactively using this information, companies can optimize their compliance strategy, minimize legal risks and make a significant contribution to global economic security.


What is the SDN list?

The abbreviation "SDN list" stands for "Specially Designated Nationals and Blocked Persons List". The US SDN list of the Office of Foreign Assets Control (OFAC) is publicly accessible and is updated regularly. It includes individuals, companies or organizations that are owned or controlled by target countries or act on their behalf and have been sanctioned by the US Treasury Department.

These entries result from serious offenses listed in non-country specific programs. These offenses jeopardize U.S. foreign policy or national security objectives. These include:

  • Human rights violations
  • terrorism involvement
  • money laundering
  • Proliferation of weapons of mass destruction
  • drug trafficking
  • Corruption

The importance of the SDN list

The SDN list acts as a protective mechanism to minimize potential risks (e.g. anti-money laundering) and to safeguard the integrity of the international financial system. Its targeted focus on individual actors enables an effective fight against illegal activities. Companies and financial institutions should actively integrate the SDN list into their compliance-strategies in order to avoid legal consequences and make a significant contribution to the security of the global economy. This integration ensures the regular screening of business partners, transactions and other relevant activities against the individuals and organizations on the SDN list. This ensures that companies do not unknowingly do business with sanctioned parties. Potential risks are identified at an early stage and appropriate measures are taken. This avoids legal consequences and minimizes significant reputational damage and financial risks.

Consequences and enforcement of the SND list

The inclusion of a person, company or organization on the SDN list has far-reaching consequences. Assets are immediately frozen and all financial resources and accounts are consequently blocked. As a result, no further transactions can take place. In extreme cases, the USA even reserves the right to seize the frozen assets.

Enforcement extends beyond the United States. Many countries join the sanctions and undertake to respect various lists, including the SDN list. US citizens as well as citizens and companies from other countries must ensure that they do not do business with SDNs. Failure to do so may result in legal penalties and fines. Therefore, it is imperative for companies and individuals worldwide to comply with the SDN List and similar sanctions lists to maintain ethical standards and avoid legal issues and financial risks.

How to use the SDN list

The OFAC offers a search engine for the SDNs search engine. This allows users to limit their search results by criteria such as countries, addresses or specific sanctions. The names found are provided with codes that describe the reason for the listing. The search uses string matching to find possible matches with entered words or strings and names in the SDN list. A slider can also be used to set the accuracy of possible matches.

When companies have high volumes of customers and transactions, it is time-consuming to manually search for every potential customer or relationship with a party. With a high volume of business, it is therefore inefficient to manually check all potential customers or company relationships individually. In this case, automated screening software and procedures can best speed up the SDN list matching process.

Automate SDN list matching

The partner screening from Pythagoras Solutions offers an automated solution to effectively match individuals and organizations against the SDN list. Successful matches automatically generate an alert, enabling organizations to identify potential risks early and proactively meet their compliance requirements.

The automated functionality of this tool provides a time and resource efficient way to identify risks. At the same time, it allows the compliance team to focus more on strategic case management. This workflow optimization ensures efficient use of relevant resources while companies maintain the highest standards of compliance and risk prevention.
