Sanctions Screening and Fuzzy Name Matching

Sanctions screening checks customers, counterparties, and transactions against official lists of designated people, organizations, vessels, or jurisdictions. OFAC’s Sanctions List Search tool uses fuzzy logic in its name search to identify potential matches on the SDN and non-SDN consolidated lists. Fuzzy matching is useful because names can have spelling variations, transliteration differences, abbreviations, and incomplete identifiers. A potential match is not a final determination that a person is designated or a transaction is prohibited. Analysts compare additional identifiers such as date of birth, address, nationality, aliases, entity registration, ownership, and transaction details. High matching sensitivity can increase false positives and review burden; thresholds that are too strict may miss variants. Screening software also needs current list data and tested configuration. OFAC’s compliance framework emphasizes management commitment, risk assessment, internal controls, testing and auditing, and training. Organizations should document list sources, update timing, matching thresholds, review procedures, escalation, and recordkeeping. Test the system with relevant name forms and maintain a process for correcting data. Avoid automatically blocking a person solely because a fuzzy score is high; investigate under the institution’s legal and compliance procedures. Product design and jurisdiction-specific legal review remain important. Screening should cover relevant customer onboarding and transaction points, and policies should define when a potential match pauses processing. Staff need a documented path to obtain additional information and to escalate unresolved cases. A screening result should be handled confidentially and consistently.
