KYC verifies individuals. KYB verifies businesses. But the line between them blurs constantly in practice — and getting it wrong creates serious compliance gaps.
Ask ten compliance professionals to define the difference between KYC and KYB and you'll get ten slightly different answers. That's a problem. In regulated industries, vague boundaries in compliance frameworks create gaps — and gaps are where financial crime hides.
The distinction matters more than ever in 2026. Regulatory bodies from FinCEN to the FCA are increasing scrutiny on beneficial ownership, shell company structures, and business verification workflows. Getting KYC and KYB right isn't just good practice — it's an enforcement priority.
KYC refers to the process of verifying the identity of an individual person before entering into a financial or regulated relationship with them. The core requirements are:
KYC is required at account opening, at defined transaction thresholds, and when risk signals trigger a re-verification. The standard was established under the Bank Secrecy Act and formalized globally through FATF Recommendation 10.
KYB refers to the process of verifying the identity and legitimacy of a business entity before entering into a commercial or financial relationship. KYB goes well beyond asking for a company registration number. A thorough KYB check includes:
The 2016 FinCEN Customer Due Diligence Rule formalized UBO requirements for US financial institutions. The EU's 5th and 6th Anti-Money Laundering Directives extended similar requirements across Europe.
The most common mistake compliance teams make is treating KYC and KYB as parallel but separate workflows. They are not. Every KYB check requires KYC checks on the humans behind the business.
Verifying that a company is legitimately registered tells you nothing about the people controlling it. Shell companies and front organizations pass company registry checks easily — it is the UBO layer that exposes beneficial ownership by sanctioned individuals, PEPs, or known fraudsters.
This means a B2B onboarding workflow is not complete until every named director and every UBO above the ownership threshold has been individually verified through a full KYC process.
| Dimension | KYC | KYB |
|---|---|---|
| Subject | Individual person | Business entity |
| Data required | Government ID, selfie, date of birth, address | Company registration, articles of incorporation, UBO register, director IDs |
| Regulations | Bank Secrecy Act, FATF Rec. 10, AML Directives | FinCEN CDD Rule, EU 5AMLD/6AMLD, UK PSC Register |
| Verification method | Document scan + biometric face match | Registry lookup + document checks + KYC on all UBOs |
| Sanctions screening | Individual (OFAC, EU, UN lists) | Entity + all beneficial owners |
| Typical use case | Retail banking, consumer lending, crypto exchange | B2B payments, business banking, commercial lending |
| Ongoing monitoring | Transaction monitoring, periodic re-KYC | Company status changes, UBO changes, annual refresh |
The trigger for KYC vs KYB depends on the nature of the relationship:
KYC applies when the counterparty is a natural person — a consumer opening an account, a borrower applying for a loan, a user onboarding to a crypto exchange, or an employee being verified for payroll purposes.
KYB applies when the counterparty is a legal entity — a business applying for a merchant account, a startup onboarding to a payment processor, a corporate client opening a trade finance facility.
Both apply simultaneously when an individual claims to be acting on behalf of a business. In this case, the individual must pass KYC (confirming their personal identity and authority to act), and the business must pass KYB (confirming the entity is legitimate and the individual is genuinely authorised).
Treating a B2B relationship as KYC-only — skipping the entity verification layer — exposes the business to several specific risks:
In fintech and banking, the consequences of a KYB failure are measured in eight figures. The 2023 Binance consent order — a $4.3 billion settlement — included specific findings about inadequate business customer verification.
deepidv's online verification platform is designed to handle both workflows within a single integration. Individual KYC flows run document verification and biometric matching for natural persons. Business onboarding flows trigger parallel verification streams — entity checks at the registry level, with individual KYC checks automatically initiated for each UBO and director identified in the company structure.
The result is a unified audit trail that covers both the entity and the humans behind it — the standard that regulators increasingly expect to see.
If your current compliance stack treats KYB as "just ask for a company registration number," you have a gap worth closing. Talk to our compliance team about what a complete KYB workflow looks like in practice.
