KYC vs AML: What is the Difference?
In brief: KYC is one part of AML: it helps a firm identify and verify a customer, while AML is the wider system for assessing risk, applying controls, monitoring, recording decisions, and escalating concerns.
Key points
- KYC focuses on knowing and verifying the customer.
- AML covers the wider controls used to prevent and detect money laundering risk.
- A firm can complete an identity check and still have an incomplete AML file.
KYC vs AML in plain English
KYC means Know Your Customer. It is the process of identifying and verifying who the customer is. AML means anti-money laundering. It is the wider system of risk assessment, customer due diligence, screening, monitoring, record keeping, training, policies, controls, and escalation.
KYC is important, but it is not the whole AML file.
The difference
| Area | KYC | AML |
|---|---|---|
| Main question | Who is the client? | What is the risk and how is it controlled? |
| Typical evidence | ID, address, verification result, company details. | Risk assessment, CDD, screening, source of funds, records, training, escalation. |
| Scope | Narrower | Broader |
| Common mistake | Treating a passed ID check as enough. | Building policies without usable client evidence. |
Example
A director passes an identity check. That is useful KYC evidence. It does not answer whether the company ownership is clear, whether the funds make sense, whether the client is a PEP, whether sanctions screening is clear, or whether the matter fits the firm's risk appetite.
Those are AML questions.
How KYC fits into a good AML workflow
- Identify the client.
- Verify the person or business.
- Understand ownership and control.
- Assess client and matter risk.
- Screen relevant people and entities.
- Collect source-of-funds or source-of-wealth evidence where needed.
- Record the decision and review trigger.
