What is Know Your Business (KYB)?

Know Your Business is the process of verifying a business customer for AML compliance: confirming the entity is real and correctly registered, mapping its ownership to the real people behind it, and screening both the entity and those owners.

KYB is the corporate counterpart to Know Your Customer. Verifying an individual is relatively direct. Verifying a business is harder, because a company can sit on top of other companies and trusts, and you have to work through them to reach the people who actually own or control it.

The three steps of KYB

WhenWhat happens
1. Verify the entityRegistration, status, details
2. Map ownershipStructure and UBOs
3. ScreenEntity + owners vs risk data

The three steps of KYB: verify the entity is real and registered, map its ownership and control to identify ultimate beneficial owners, then screen the entity and those owners against risk data.

KYB works in three steps: verify the business, map its ownership to the ultimate beneficial owners, then screen the entity and those people.

Why KYB matters

Without KYB, a corporate customer can pass onboarding while a sanctioned or high-risk person sits behind it. KYB is central to onboarding business customers under AML obligations, and it is a core requirement for many of the sectors newly captured by Tranche 2, such as accountants and real estate professionals dealing with corporate clients and trusts.

Questions

Common questions about what is know your business (kyb)?.

What is the difference between KYC and KYB?
KYC verifies an individual customer. KYB verifies a business customer, which is more involved because you must confirm the entity itself, map its ownership structure, and identify and screen the natural people who ultimately own or control it.
What does KYB check?
KYB confirms the business exists and is correctly registered, establishes its ownership and control structure, identifies the ultimate beneficial owners, and screens the entity and those owners against sanctions, PEP and adverse-media data.
Why is KYB important?
A company can be used to disguise who is really behind a transaction. KYB reveals the real owners so they can be screened, which is essential for onboarding corporate customers under AML obligations, including Tranche 2.
