KYB vs KYC: What Is the Difference?

KYB and KYC are two distinct due diligence processes that are often confused. Both exist to verify who you are doing business with, but they apply to different types of counterparties and require different data sources, processes, and regulatory frameworks.

What Is KYC?

Know Your Customer (KYC) is the process of verifying the identity of individual consumers. It is a cornerstone of anti-money laundering (AML) compliance in financial services and involves collecting and verifying personal identification documents, address proof, and screening individuals against sanctions and PEP lists.

What Is KYB?

Know Your Business (KYB) is the equivalent process for legal entities. Instead of verifying a person, KYB verifies that a business is legitimate, legally registered, active, and controlled by the people it claims to be controlled by. This includes confirming registration details, identifying directors and shareholders, resolving ultimate beneficial ownership (UBO), and screening the entity and its owners against relevant watchlists.

Key Differences Between KYB and KYC

Who is being verified: KYC verifies individuals. KYB verifies legal entities.

Data sources: KYC uses identity documents and personal databases. KYB uses corporate registries, regulatory filings, and UBO registers.

Complexity: Business entities can have multiple layers of ownership through holding companies and nominee structures. KYB must resolve these layers to reach the actual controlling individuals.

Ongoing monitoring: Both require ongoing monitoring, but KYB must also track corporate events such as ownership changes, mergers, and dissolution.

Regulatory framework: KYC obligations are well established. KYB requirements are evolving rapidly, particularly around UBO disclosure and beneficial ownership registers.

When You Need KYB vs KYC

KYC applies when onboarding individual consumers, retail banking customers, or personal account holders. KYB applies when onboarding business customers, corporate clients, vendors, suppliers, or any legal entity counterparty. Many compliance programs require both: KYC for the individual representatives of a business, and KYB for the entity itself.

Frequently Asked Questions

Can KYB replace KYC?
No. KYB verifies the business entity. KYC verifies the individuals associated with it. A complete compliance program typically requires both.

Is KYB mandatory?
KYB requirements vary by jurisdiction and sector. Financial institutions are generally required to conduct KYB under AML regulations. Other sectors increasingly adopt KYB voluntarily for vendor risk management and fraud prevention.

What data is needed for KYB?
KYB requires legal name, registration number, jurisdiction, company status, registered address, director information, ownership structure, and UBO identification.

How long does a KYB check take?
With automated data, a KYB check can be completed in seconds for straightforward entities. Complex ownership structures with multiple jurisdictions may require additional manual review.
