What is KYC?

KYC (Know Your Customer) is the process of identifying and verifying a customer so that a business can understand who it is establishing a relationship with. KYC is particularly important for banks, fintech companies, payment institutions, crypto businesses, and other regulated entities.

KYC commonly includes collecting and verifying personal or corporate information, checking beneficial ownership, assessing the customer profile, and determining the level of risk. KYC is not a substitute for the broader AML framework, but rather one of its key components.

KYC definition

KYC (Know Your Customer) is the process used by a business to establish a customer’s identity, verify the information provided, and build a basic understanding of the customer’s profile and potential risk.

For individuals, KYC may include:

• Full name;
• Date of birth;
• Residential address;
• Identity document;
• Nationality;
• Tax residence;
• Occupation or source of income.

For corporate customers, the review is usually broader and may cover:

• Company name and registration details;
• Registered address;
• Directors and authorised representatives;
• Ownership structure;
• Beneficial owners;
• Nature of business;
• Expected transaction activity.

In simple terms

KYC helps a business answer a basic question: who is this customer, and can their identity and business profile be reliably verified?

How does KYC work?

The KYC process usually begins during customer onboarding and may continue throughout the business relationship. The depth of the review depends on the customer type, jurisdiction, product, and level of risk.

A typical process includes:

• Data collection. The business obtains personal or corporate information about the customer.
• Identity verification. The information is checked against documents, official registries, or other reliable sources.
• Beneficial ownership check. For corporate customers, the business identifies who ultimately owns or controls the entity.
• Customer profiling. Occupation, business activity, geography, expected transactions, and other relevant factors are assessed.
• Risk classification. The customer is assigned a risk level.
• Ongoing review. Information is updated when ownership, activity, documents, or other material details change.

If a customer falls into a higher-risk category, standard KYC may not be sufficient. Additional measures may then be required under Enhanced Due Diligence.

KYC and customer risk assessment

After completing basic KYC verification, a business usually assesses the customer’s level of risk. This helps determine whether standard checks are sufficient or whether additional measures are required.

A risk assessment may consider:

• Country of residence or incorporation;
• Occupation or type of business;
• Ownership structure;
• Source of funds and expected transaction activity;
• Exposure to high-risk jurisdictions;
• PEP status;
• Sanctions exposure;
• Complexity of the corporate structure;
• Unusual or high-value transactions.

Based on these factors, a customer may be classified as low, medium, or high risk.

Higher-risk customers generally require deeper review, additional documentation, and Enhanced Due Diligence. Risk classification should not be treated as a formality; it should reflect the customer’s actual profile and the nature of the business relationship.

Where is KYC used?

KYC is used in industries where businesses need to understand who their customers are and what level of financial or regulatory risk is associated with the relationship.

KYC is particularly common in:

• Banking;
• Payment services;
• Fintech;
• Crypto exchanges and other CASPs;
• Investment services;
• Insurance;
• Lending;
• Money transfer businesses;
• Other regulated financial activities.

For example, a crypto platform may perform KYC before allowing a customer to deposit, exchange, or withdraw funds. A payment institution may verify the identity and ownership structure of a corporate customer before opening an account or providing payment services.

The exact scope of KYC depends on the business model and jurisdiction. Some customers may require only standard verification, while others need a more detailed review.

Examples of KYC

KYC is applied differently depending on the customer type, product, and level of risk.

Example 1. Individual customer

A customer opens an account with a fintech app. The company verifies an identity document, personal details, address, and basic information about the source of income.

Example 2. Corporate customer

A business applies for a payment account. The provider verifies registration details, directors, ownership structure, and beneficial owners.

Example 3. Higher-risk client

A customer is linked to a high-risk jurisdiction or has a complex ownership structure. The business requests additional documents and applies Enhanced Due Diligence.

Example 4. Periodic KYC update

A corporate customer changes its beneficial owner. The regulated business updates the KYC profile and reassesses the customer’s risk.

KYC vs AML

KYC and AML are closely related, but they are not the same. KYC focuses mainly on identifying customers and assessing their risk profile, while AML covers a broader set of measures designed to prevent money laundering and related financial crime.

In simple terms, KYC is part of the AML framework. A business may verify a customer’s identity, but a complete AML program usually also requires transaction monitoring, sanctions controls, and procedures for addressing suspicious activity.

Frequently Asked Questions

What does KYC mean?

KYC (Know Your Customer) is the process of identifying and verifying a customer so that a business can confirm their identity, understand their profile, and assess potential risk.

What documents are required for KYC?

Individuals are usually asked to provide an identity document and evidence supporting key personal details. Companies may need to provide registration documents, ownership information, details of directors, and beneficial owner information. Exact requirements depend on the jurisdiction and risk level.

How long does KYC take?

The timeframe depends on the complexity of the customer and the quality of the information provided. A simple individual verification may be completed quickly, while corporate KYC involving a complex ownership structure can take considerably longer.

Does KYC need to be repeated?

Yes. Regulated businesses may periodically update KYC information or conduct a review following material changes, such as a new beneficial owner, address, business activity, or risk profile.

Can a business reject a customer after KYC?

Yes. If a business cannot reliably verify the customer’s identity, understand the ownership structure, or obtain sufficient information to assess risk, it may refuse onboarding or terminate the business relationship in accordance with applicable requirements.
