Customer due diligence (CDD) is the standard set of checks a firm runs on every customer to verify identity and assess risk.
Enhanced due diligence (EDD) is the deeper set of checks applied only to higher-risk customers, adding source-of-funds verification, beneficial-ownership mapping, and closer monitoring.
CDD is the baseline that applies to everyone; EDD is the escalation for higher risk.
What does enhanced due diligence involve?
EDD goes further than a standard identity check.
It typically includes deeper background research on the customer and their beneficial owners, verification of the sources of funds and wealth, closer and more frequent adverse media screening, and tighter ongoing monitoring throughout the relationship. Where standard due diligence answers “who is this customer,” EDD answers “what is the full picture of the risk they carry.”
CDD vs EDD at a glance
| Customer due diligence (CDD) | Enhanced due diligence (EDD) | |
|---|---|---|
| Applies to | All customers | Higher-risk customers only |
| Purpose | Verify identity, assess risk | Understand a high-risk relationship fully |
| Depth | Standard identity and risk checks | Deeper research, verification, monitoring |
| Source of funds | Not usually required | Verified |
| Beneficial ownership | Basic identification | Mapped and verified |
| Adverse media | Standard screening | Closer, ongoing screening |
| Monitoring | Periodic | Enhanced and more frequent |
| Trigger | Applies by default | Higher assessed risk |
What is customer due diligence (CDD)?
CDD is the baseline check every regulated firm runs on its customers. It confirms the customer’s identity, understands the nature of the relationship, and assesses the level of risk they present.
For most customers, CDD is sufficient on its own. It’s the standard front-door process of knowing who you’re dealing with.
What is enhanced due diligence (EDD)?
EDD is the deeper level of scrutiny applied when a customer or counterparty presents higher risk. It adds source-of-funds and source-of-wealth verification, beneficial-ownership mapping, closer adverse media screening, and tighter ongoing monitoring.
The goal is a full understanding of a high-risk relationship, not just a verified identity.

When does a customer move from CDD to EDD?
The shift happens when risk is assessed as higher than standard.
Common triggers include politically exposed persons, customers in high-risk jurisdictions, correspondent banking relationships, complex or opaque ownership, and unusual transaction patterns.
Under a risk-based approach, the move to EDD is driven by risk level rather than a fixed category.
(For the detail, see our guide on when EDD is required.)
Where does adverse media fit in CDD and EDD?
Both CDD and EDD involve adverse media screening, but at different intensities.
CDD includes standard screening; EDD requires closer, ongoing checks because the stakes are higher.
In both cases, the screening is only as good as the news coverage behind it.
Risk on a high-risk counterparty often breaks first in local-language reporting, so for EDD especially, the breadth and language reach of the underlying data directly affect whether the deeper scrutiny actually catches what it should.

FAQ
What is enhanced due diligence in AML?
In anti-money laundering, enhanced due diligence is a deeper set of checks applied to higher-risk customers: source-of-funds verification, beneficial-ownership mapping, closer adverse-media screening, and ongoing monitoring.
It goes beyond standard due diligence to build a fuller picture of a high-risk relationship.
What is the purpose of enhanced due diligence?
The purpose is to understand and manage the risk of relationships that standard checks can't adequately assess. For higher-risk customers and counterparties, EDD surfaces the deeper information, ownership, funds, and adverse history that a basic identity check would miss.
What is the difference between CDD and EDD?
Customer due diligence (CDD) verifies identity and assesses risk for all customers. Enhanced due diligence (EDD) applies to higher-risk cases and involves deeper research, verification, and monitoring.
CDD is the baseline; EDD is the escalation.
