KYC vs KYB is the key compliance difference this guide explains in more detail. If you have already read our explainer on what separates Know Your Customer from Know Your Business, this guide goes one level deeper. The conceptual difference is settled: KYC verifies individuals, while KYB verifies businesses and the people behind them. The harder questions are practical: what does each process actually require, which laws compel them, and when do you need one, the other, or both? This article answers those questions with the use cases that matter for fintech, payments, and embedded finance.
KYC vs KYB: The Difference in One Line
KYC confirms that a person is real and assesses their risk. KYB confirms that a company is legitimate, identifies its Ultimate Beneficial Owners (UBOs), and then applies KYC to each of them. KYB is therefore the larger process, it contains KYC. For the full conceptual breakdown, see our companion guide, “KYB vs KYC: What Is the Difference?”
KYC requirements and process
A compliant KYC programme rests on four requirements:
- Customer Identification Programme (CIP): collect and verify four core data points, full name, date of birth, residential address and an identity number, against a government ID and a biometric liveness check.
- Customer Due Diligence (CDD): screen the individual against sanctions, PEP and watch-lists; establish the purpose of the relationship; assign a risk rating.
- Enhanced Due Diligence (EDD): for higher-risk customers, investigate source of funds and source of wealth and gather additional documentation.
- Ongoing monitoring: continuously monitor transactions and behaviour against the risk profile, and file suspicious activity reports where warranted.
KYB requirements and process
KYB carries every KYC requirement plus a layer of corporate verification:
- Business registration verification: confirm the legal name, registration number, status and registered address against official registries, and collect incorporation documents.
- Ownership mapping and UBO identification: trace the ownership chain and identify every natural person owning 25% or more, or exercising substantial control, then run full KYC on each.
- Screening: check the entity, its directors and its UBOs against sanctions, PEP and adverse-media databases.
- Risk assessment: determine the nature of the relationship and assign an entity-level risk rating, applying EDD to high-risk corporates.
- Ongoing monitoring and recordkeeping: watch for changes in ownership, status or risk, and retain an auditable record of every check. The KYB side of a KYC vs KYB workflow verifies the business entity, ownership structure, and beneficial owners.
The regulatory frameworks behind each
Both processes trace back to the FATF recommendations on customer due diligence and beneficial ownership, localised into regional regimes. The table below summarises the position in 2026.
| Regime | What it requires | 2025–2026 note |
|---|---|---|
| FATF (global standard) | CDD on customers; identify and verify beneficial owners; 25% threshold plus substantial control | The source standard all regions localise |
| US FinCEN CDD Rule | Identify any 25%+ owner plus one control person at account opening | Feb 2026 relief eased re-verification at each new account, not a repeal |
| US Corporate Transparency Act | Central beneficial-ownership register | Mar 2025 rule limited reporting to foreign entities only |
| EU AMLR / AMLD6 | Identify UBOs at 25%+; mandatory ongoing monitoring; officer liability | Applies from 10 July 2027; AMLA authority operational since Jul 2025 |
| UK MLR 2017 | Risk-based CDD and EDD; beneficial-ownership checks | Amended Nov 2025; further changes targeted for 2026 |
The headline shift is in the US: beneficial-ownership reporting under the Corporate Transparency Act now applies only to foreign entities, so US KYB leans more heavily on registry and IRS data. Critically, the obligation on banks and fintechs to perform KYB at onboarding is unchanged.
KYC vs KYB Use Cases: When You Need Which
The deciding factor is simple, who is your customer?
- KYC only: consumer-facing products where the customer is always an individual, a neobank current account, a retail trading app, a peer-to-peer wallet.
- KYB plus KYC: any product onboarding businesses, B2B payments, merchant acquiring, business lending, supplier marketplaces, and embedded-finance programmes where the end customer is a company.
- Both, at different points: marketplaces and platforms that serve individual buyers (KYC) and business sellers (KYB) in the same flow.
Industry use cases
Fintech and payments
A payments platform onboarding merchants must verify each business and its owners before enabling money movement, KYB is the gatekeeper to the account, with KYC on the directors and UBOs.
Crypto and digital assets
Exchanges and custodians face heightened AML scrutiny; institutional clients require full KYB with deep UBO analysis, while retail users go through KYC.
Lending and BNPL
Business lenders combine KYB with financial-activity data to confirm a borrower is both real and operating, before underwriting.
Embedded finance and BaaS
Here the platform usually holds contractual liability for fraud losses, so KYB is part of the product, not the back office, it must match host-platform onboarding speed while satisfying the sponsor bank’s compliance requirements.
Building a compliant onboarding stack
The practical challenge is that KYB has historically been slow and manual, while embedded products deliver onboarding at product-channel volume. The resolution is orchestration: a single, API-driven flow that verifies the entity, discovers UBOs, runs AML screening on the business and its owners, and returns an auditable decision, escalating only genuine edge cases to a human. A strong KYC vs KYB onboarding stack should combine identity verification, business verification, AML screening, and ongoing monitoring.
- Match jurisdictions to coverage: confirm your specific markets are supported by live, primary-source registry connections before you commit.
- Automate UBO traversal: require automated mapping through multi-layer and cross-border structures, not manual lookups.
- Screen owners, not just entities: sanctions, PEP and adverse-media checks must extend to every UBO and director.
- Adopt perpetual monitoring: move from one-off onboarding checks to lifecycle monitoring of ownership and risk changes.
Frequently asked questions
KYC vs KYB: What Is the Main Difference?
KYC verifies individual customers; KYB verifies business entities and the people who own or control them. KYB includes KYC on each beneficial owner.
What documents does KYB require?
Company registration and incorporation documents, registration number, ownership-structure details, UBO identification, and, for higher-risk cases, financial statements or proof of activity, all cross-checked against official registries.
Is KYB legally required?
For regulated firms, yes, under regimes such as the EU’s AMLR/AMLD6, the US FinCEN CDD Rule and the UK MLR 2017. Reporting under the US Corporate Transparency Act now applies only to foreign entities, but firms must still perform KYB on counterparties.
How long does KYB verification take?
From minutes with automated platforms to several days when complex ownership or missing registry data triggers manual review.
Can one provider handle both KYC and KYB?
Yes. All-in-one and orchestration platforms run entity verification, UBO discovery and individual KYC in a single workflow, which is the model embedded-finance providers typically adopt.
