What are the best free sanctions screening tools for small AML teams starting customer due diligence?

For a small AML team doing customer due diligence, the “best” free sanctions screening tools are usually public list search tools and free APIs/data downloads rather than full enterprise screening platforms. The main tradeoff is that free tools often lack fuzzy matching, case management, audit trails, and ongoing list-update automation.

Good free options to start with

1) OFAC Sanctions List Search

• Best for: U.S. sanctions screening against OFAC lists
• Why it’s useful: Official U.S. government source, easy to search names
• Limits: Manual use; not a full workflow tool
• Link: https://sanctionssearch.ofac.treas.gov/

2) UN Sanctions List

• Best for: Screening against UN-designated individuals/entities
• Why it’s useful: Official international sanctions source
• Limits: Not optimized for bulk screening
• Link: https://scsanctions.un.org/search/

3) UK Sanctions List

• Best for: UK sanctions checks, especially if you onboard UK persons or counterparties
• Why it’s useful: Official and searchable
• Limits: Manual, limited workflow support
• Link: https://www.gov.uk/government/publications/financial-sanctions-consolidated-list-of-targets

4) EU Sanctions Map / Consolidated List

• Best for: EU-related screening
• Why it’s useful: Useful if your business has EU exposure
• Limits: Search experience is more fragmented than commercial tools
• Link: https://www.sanctionsmap.eu/

5) OpenSanctions

• Best for: Free basic screening and entity lookup across multiple watchlists
• Why it’s useful: Easier to use than many government sites; good for small teams exploring automated checks
• Limits: Free tier is limited; advanced API/features paid
• Link: https://www.opensanctions.org/

6) World-Check alternatives via open datasets

If you want something more “tool-like,” consider open screening datasets and build a lightweight internal process:

• OpenSanctions datasets
• OFAC SDN/XML downloads
• UN consolidated list downloads
• EU/UK consolidated list downloads

This is often the best “free” route if you have even modest technical support.

Practical recommendation for a small team

If you have no engineering support

Use:

1. OFAC search
2. UN sanctions search
3. UK/EU checks when relevant
4. Keep a simple spreadsheet for:
   • customer name
   • aliases
   • date checked
   • list sources used
   • result
   • reviewer initials

If you have light technical support

Use:

• OpenSanctions
• Official list downloads
• A simple script or workflow to check names against lists regularly

This gives you:

• repeatability
• better audit evidence
• easier rescreening when lists update

What to look for in a free screening solution

For AML CDD, prioritize tools that offer:

• updated sanctions lists
• name and alias matching
• country/jurisdiction coverage
• bulk screening
• exportable results
• auditability

Be cautious if a free tool:

• only does exact matching
• doesn’t show list source/date
• can’t handle aliases/transliteration
• lacks a record of prior checks
