Sanctions Data Sources

Sanctions data sources are dynamic lists, notices and tools used to identify designated persons, entities, vessels, aircraft and other restricted subjects. Sanctions screening must be treated separately from ordinary adverse media because a true match may trigger immediate legal and operational consequences.

1. Core official sources #

Source What it provides Use in AML/KYC/KYB Limitation
UN Security Council Consolidated List UN listed individuals and entities in downloadable formats Global TFS baseline National implementation may add local details
OFAC Sanctions List Search / OFAC lists US SDN and non-SDN search, fuzzy matching and list data US sanctions exposure and entity matching Applicability depends on legal scope and policy overlay
EU Sanctions Map / EU consolidated data EU sanctions regimes, measures and designated subjects EU sanctions exposure Must distinguish map guidance from source list data
UK Sanctions List UK sanctions designations UK sanctions exposure Current UK source; older OFSI consolidated list is historical/reference-only from 28 January 2026
OpenSanctions Aggregated sanctions, PEP and risk datasets from many sources Discovery, enrichment and cross-source matching Aggregator, not a sanctions authority

2. Matching logic #

A sanctions source hit should be classified carefully:

Result Meaning Evidence action
No apparent match No relevant result at the checked time Record source and date
False positive Name similar but identifiers do not support match Record why ruled out
Possible match Some overlap, not enough identifiers Escalate for review and collect more non-sensitive identifiers
Likely match Strong identifier overlap Escalate immediately
True match Confirmed designation or ownership/control link Follow local sanctions procedure

3. Data points to compare #

  • full legal name;
  • aliases and transliterations;
  • date of birth or incorporation date;
  • place of birth or registration jurisdiction;
  • nationality or registration number;
  • addresses;
  • vessels, aircraft, IMO numbers or other identifiers;
  • ownership/control links;
  • source list and programme/regime.

4. Evidence value #

Official list entries have high evidence value for the fact of designation. However, the legal consequence depends on the jurisdiction, the institution's obligations, the customer relationship, ownership/control analysis and local policy.

Aggregators have strong discovery value but important matches should be traced to the original list before relying on them.

5. Source basis #

6. Boundary #

Boundary: source types and evidence handling only. Legal sanctions obligations require the applicable authority, programme, list version and local rule.
