OFAC Sanctions Screening & Database Review
Our lawyers review your OFAC sanctions screening program, identify compliance gaps, and represent clients facing enforcement action for missed SDN list hits. Protect your business with a robust, legally sound screening architecture.
OFAC sanctions screening is the process of checking individuals, entities, transactions, and business relationships against U.S. government and international sanctions databases to ensure compliance with applicable sanctions regulations. The Collegium of International Lawyers advises corporations, financial institutions, and non-profit organizations worldwide on building robust screening programs — and represents those facing OFAC enforcement for screening failures.
What Is OFAC Sanctions Screening?
OFAC sanctions screening is the mandatory review of counterparties, transactions, employees, and business partners against the Specially Designated Nationals (SDN) list, the OFAC Consolidated Sanctions List, and other applicable international databases. Under 31 C.F.R. Parts 500–599 and the International Emergency Economic Powers Act (IEEPA), U.S. persons are strictly liable for any prohibited dealing with a designated party — meaning liability applies even without knowledge or intent.
A missed screening hit that results in a completed transaction with a sanctioned person can expose your organization to civil penalties of up to $1.3 million per violation, criminal prosecution, and reputational damage. Over 20,000 individuals and entities are currently listed on the SDN list — and the list is updated in real time, sometimes multiple times per day.
Who Must Conduct OFAC Sanctions Screening?
All U.S. persons — including U.S. citizens and permanent residents wherever located, U.S.-incorporated entities and their foreign branches, and any person physically present in the United States — must screen against OFAC sanctions databases. Foreign companies are also required to screen when their transactions involve U.S. persons, U.S. goods, or U.S. dollar-denominated payments through U.S. correspondent banks.
In practice, screening obligations apply across all industries and extend to: customers and clients at onboarding, vendors and suppliers, employees and contractors, transaction counterparties, beneficial owners of legal entities, intermediary banks and payment processors, and charity beneficiaries and grant recipients. OFAC enforcement actions have targeted banks, exporters, manufacturers, logistics companies, insurers, real estate firms, and educational institutions.
Key Sanctions Databases for Screening
| Database | Administered By | Who Must Screen | Update Frequency | Penalty for Miss |
|---|---|---|---|---|
| OFAC SDN List | U.S. Treasury / OFAC | All U.S. persons (strict liability) | Real-time / daily | Up to $1.3M per violation; up to 20 years criminal |
| OFAC Consolidated Sanctions List | U.S. Treasury / OFAC | All U.S. persons and their transactions | Frequent — incorporates SDN + SSI + FSE | Up to $1.3M per violation; reduced by VSD and SCP |
| EU Consolidated List | European Commission | EU entities; U.S. firms with EU nexus | Weekly / as designations change | Varies by member state; fines and asset freezes |
| UN Consolidated List | UN Security Council | All UN member states (via national law) | As Security Council acts | Nationally enforced — aligns with U.S./EU penalties |
OFAC Screening Process and Compliance Tools
An effective OFAC sanctions screening program operates across four layers: list management (ensuring your screening tool uses the most current SDN and consolidated lists, updated automatically), name matching (applying fuzzy logic to catch name variations, transliterations, and aliases), hit review (a documented process for investigating potential matches and clearing false positives), and transaction blocking (a mechanism to halt prohibited transactions pending review).
OFAC does not mandate a specific screening tool, but expects that organizations choose solutions commensurate with their risk profile. High-volume payment processors require automated real-time screening. Trade finance institutions need screening at the deal, counterparty, and goods level. Non-profits making overseas grants must screen beneficiaries, grantees, and implementing partners. Our attorneys review your existing screening architecture, identify gaps, and recommend remediation steps that satisfy OFAC regulatory expectations.
Consequences of Failing OFAC Screening
OFAC enforcement for screening failures is aggressive and unpredictable. A manufacturing company paid $4.4 million for 223 SDN list breaches caused by an outdated screening database. A Florida school was penalized in early 2026 for accepting tuition payments routed through cartel-linked sanctioned parties — a case where the ultimate sanctions nexus was several steps removed from the institution. OFAC enforcement in 2023–2024 exceeded $1 billion in total penalties.
Beyond direct financial penalties, sanctions screening failures can result in: loss of U.S. correspondent banking access, reputational damage affecting institutional relationships, criminal referral to the Department of Justice for willful violations, and regulatory debarment from U.S. government contracts. Companies that discover a screening gap should immediately consult sanctions counsel, assess the scope of potential violations, implement corrective screening procedures, and evaluate whether Voluntary Self-Disclosure to OFAC is appropriate.
Frequently Asked Questions
What is an OFAC SDN check?
An OFAC SDN check is the process of searching a party (person, company, or entity) against the Specially Designated Nationals and Blocked Persons (SDN) list maintained by the U.S. Treasury Office of Foreign Assets Control. A positive match means U.S. persons are prohibited from completing any transaction with that party. SDN checks should be performed at onboarding, before each transaction, and whenever the SDN list is updated. Automated screening tools perform these checks in real time.
Who is required to perform OFAC screening?
All U.S. persons — including U.S. companies, their foreign branches, U.S. citizens, and permanent residents — are required to conduct OFAC screening. Foreign companies are also required to screen when their transactions involve U.S. persons, U.S. dollar payments, or U.S.-origin goods. High-risk industries with mandatory screening programs include banking, insurance, trade finance, export/import, real estate, and non-profit organizations distributing funds internationally.
How often should companies screen against OFAC lists?
OFAC recommends that companies screen at the point of onboarding and then on an ongoing basis whenever the sanctions lists are updated — which can occur multiple times per day. For high-volume transaction processors, real-time screening at the transaction level is required. Static one-time screening at onboarding is insufficient: a counterparty not listed when onboarded can be added to the SDN list at any time, making subsequent transactions a violation. Automated screening solutions update list data continuously.
What happens if my company misses an OFAC screening hit?
If your company completes a transaction with an SDN-listed person due to a screening failure, you may face civil penalties of up to $1.3 million per violation under IEEPA, regardless of intent. OFAC applies strict liability — ignorance of the designation is not a defense. However, a documented sanctions compliance program and Voluntary Self-Disclosure can significantly reduce penalties. Our attorneys conduct post-violation assessments, prepare VSD submissions, and negotiate with OFAC to minimize enforcement consequences.
Can foreign companies be subject to OFAC screening requirements?
Foreign companies are subject to OFAC screening requirements when their transactions touch U.S. jurisdiction — through U.S. persons, U.S. dollar clearing, U.S.-origin goods, or U.S. financial infrastructure. Foreign companies that fail to screen for SDN-listed parties in U.S.-nexus transactions face the same civil and criminal penalties as U.S. persons. Additionally, foreign companies can face secondary sanctions for significant dealings with sanctioned jurisdictions even without a direct U.S. nexus. Our attorneys advise non-U.S. companies on their OFAC screening obligations.
