When to Use Which Sanctions Checks

Choosing the right type of sanctions check can make the difference between a compliant, efficient process and one that’s risky, costly, or ineffective.

---

1. Onboarding New Customers or Vendors

When first engaging with a new client, supplier, or partner, a comprehensive (full list) check is the safest approach.
This ensures the subject is screened against all relevant sanctions lists, even if you operate in only one jurisdiction.

Pro Tip: Combine with PEP (Politically Exposed Person) screening during onboarding.

2. Ongoing Monitoring

For customers and partners you already work with, periodic rescreening helps keep your database aligned with sanctions list changes.
If your sector or corridors change quickly (e.g., fintech, crypto, trade), shorten the re-screening interval and document the trigger points you rely on.

---

3. Jurisdiction-Specific Operations

If your business operates exclusively in a certain jurisdiction, targeted checks can help cut down false positives.
For example, an EU-only business might focus on EU Consolidated Lists.

⚠️ Ensure you still comply with any cross-border sanctions obligations if you have foreign clients.

4. Large Data Imports

When migrating data or onboarding a large group at once, batch screening via CSV upload or API is efficient.
This is also ideal for periodic "whole book" reviews.

---

5. Investigations and One-Off Checks

If you receive a suspicious payment or need to screen a one-time supplier, ad-hoc/manual checks are appropriate.
These are quick, targeted lookups without affecting your entire customer base.
