Every business relationship starts with a question: Is this company real — and is it safe to work with?
That question is the foundation of KYB.
KYB stands for Know Your Business. It is the process of verifying a company's legal identity, ownership structure, financial health, and risk profile before entering into a business relationship.
Banks do it before opening a corporate account. Fintechs do it before onboarding a merchant. Enterprises do it before signing a vendor contract. And regulators require it under anti-money laundering (AML) laws in virtually every major economy.
If KYC (Know Your Customer) verifies individuals, KYB verifies the companies behind them.
This guide covers everything: what KYB involves, who needs it, the regulations driving it, how to build a KYB process from scratch, and how automation is replacing manual checks.
Why KYB Exists
KYB was born from a regulatory gap.
For decades, financial institutions were required to verify individual customers through KYC. But businesses? They were largely exempt. This created a loophole that criminals exploited through shell companies, layered ownership structures, and nominee directors.
The 2016 Panama Papers leak made this gap impossible to ignore. More than 11.5 million documents from the law firm Mossack Fonseca exposed how shell companies were used to launder money, evade taxes, and hide assets across borders. The leak implicated heads of state, billionaires, and criminal networks — and revealed that the existing regulatory framework had no effective mechanism to verify who actually owned and controlled business entities.
Scale of the problem: The United Nations Office on Drugs and Crime estimates that money laundering accounts for 2–5% of global GDP annually — between $800 billion and $2 trillion. Meanwhile, merchant losses from online payment fraud alone are projected to exceed $362 billion globally between 2023 and 2028.
In 2016, the U.S. Financial Crimes Enforcement Network (FinCEN) closed the gap by adding beneficial ownership requirements to its Customer Due Diligence (CDD) Rule. Europe followed with the 4th Anti-Money Laundering Directive (AMLD4), which explicitly required KYB verification for regulated entities.
Today, KYB is not optional. It is a legal obligation for any organization that forms business-to-business relationships in regulated industries.
What Does the KYB Process Involve?
A complete KYB verification checks five things:
1. Entity Verification
Confirm the company exists and is legally registered. This means checking:
- Legal name and trading name
- Registration number
- Date of incorporation
- Registered address
- Company status (active, dissolved, struck off)
- Legal form (LLC, Ltd, GmbH, SA, etc.)
The most reliable source for this data is the official government registry in the company's jurisdiction. In the UK, that is Companies House. In the US, it is the Secretary of State in each state. In Germany, it is the Handelsregister. Platforms like Global Database connect directly to 400+ of these registries across 200+ countries, pulling verified records in real time rather than relying on stale or second-hand data.
2. Ownership and UBO Identification
Identify who owns and controls the company. This is the hardest part of KYB — and the most important.
Ultimate Beneficial Owners (UBOs) are the natural persons who ultimately own or control a legal entity. Most jurisdictions define a UBO as someone who holds 25% or more of the shares or voting rights, or who exercises control through other means.
But ownership is rarely straightforward. Companies own other companies. Trusts hold shares. Nominees sit on boards. Offshore vehicles add layers. Tracing through these structures to find the real person in control is what makes KYB complex.
A proper KYB check maps: Direct shareholders and their ownership percentages · Indirect ownership through parent companies and holding structures · Directors, officers, and key executives · The full corporate hierarchy (subsidiaries, parents, affiliates) · The natural persons who qualify as UBOs.
3. Screening and Watchlist Checks
Once you know who owns and runs the company, screen them:
- Sanctions lists — OFAC (US), EU Consolidated List, UN Security Council, HMT (UK)
- PEP screening — Politically Exposed Persons who carry higher corruption risk
- Adverse media — Negative news related to fraud, money laundering, corruption, or criminal activity
If a UBO or director appears on a sanctions list, the relationship must be blocked. If they are a PEP, enhanced due diligence is required.
4. Financial Health Assessment
Verify the company is financially stable and operating as expected:
- Annual financial statements (balance sheet, income statement, cash flow)
- Credit scores and credit limit recommendations
- Filing history and compliance with local reporting requirements
- Revenue trends and profitability indicators
A company that claims to be a major exporter but reports zero revenue is a red flag. Financial data from official registry filings provides an independent, verifiable check on whether a business is what it claims to be.
5. Ongoing Monitoring
KYB is not a one-time event. Companies change. Directors resign. Ownership shifts. Financial health deteriorates. A company that was low-risk at onboarding can become high-risk six months later.
Ongoing monitoring means tracking changes in company status, monitoring ownership changes and new UBOs, re-screening against updated sanctions and PEP lists, reviewing updated financial filings, and flagging adverse media mentions.
Regulatory frameworks like AMLD6 and FATF Recommendations explicitly require ongoing monitoring as part of the KYB obligation.
KYB vs. KYC: What Is the Difference?
KYB and KYC are both part of the anti-money laundering framework, but they apply to different subjects.
| KYB (Know Your Business) | KYC (Know Your Customer) | |
|---|---|---|
| Subject | Business entities | Individual persons |
| Verifies | Company registration, ownership, UBOs, financials | Identity documents, address, source of funds |
| Data sources | Government registries, corporate filings, credit bureaus | Passports, utility bills, bank statements |
| Key challenge | Tracing multi-layer ownership structures | Document fraud and identity spoofing |
| Regulation | FinCEN CDD Rule, AMLD4/5/6, FATF Rec. 24 | FinCEN CDD Rule, AMLD, FATF Rec. 10 |
In practice, KYB and KYC overlap. When you identify a company's UBOs, you then need to run KYC checks on those individuals. The two processes work together.
Who Needs KYB?
KYB is legally required for regulated entities. But the business case extends far beyond compliance.
Legally Required
- Banks and financial institutions
- Insurance companies
- Payment processors and money service businesses
- Crypto exchanges and virtual asset service providers
- Investment firms and asset managers
- Fintechs offering lending, payments, or accounts
- Auditors, notaries, and legal professionals
- Real estate agents and dealers in high-value goods
Commercially Critical
- Procurement teams verifying suppliers before signing contracts
- Marketplace operators onboarding sellers and merchants
- Enterprise sales teams qualifying prospects and partners
- Investors conducting due diligence on portfolio companies
- Insurance underwriters assessing policyholder risk
Any organization that forms B2B relationships has a business case for KYB — whether regulation demands it or not.
What Happens When KYB Fails?
The cost of getting KYB wrong is not theoretical. Regulators across every major jurisdiction are enforcing AML violations with increasing severity — and the penalties go far beyond fines.
Regulatory Fines
AML-related fines routinely reach into the hundreds of millions. Under the new EU AML framework, AMLA can impose fines of up to 10% of annual turnover or €10 million. In the US, FinCEN and OCC penalties have exceeded $1 billion in single enforcement actions.
Criminal Liability
Senior compliance officers, directors, and even CEOs can face personal criminal charges for failures in AML controls. AMLD6 expanded the list of predicate offences and introduced harsher custodial sentences.
Loss of Banking Relationships
Correspondent banks and payment processors will de-risk and sever relationships with institutions that have weak KYB controls. Losing banking access can be existential for a fintech or payment company.
Reputational Damage
Enforcement actions are public. Once a firm is associated with facilitating money laundering or onboarding sanctioned entities, the reputational damage affects client retention, investor confidence, and the ability to close new deals.
The pattern is consistent across every major enforcement action: the root cause is almost always insufficient verification at onboarding — companies that were never properly checked, ownership structures that were never fully mapped, and screening that was never performed or never updated.
The Regulatory Landscape for KYB in 2026
KYB requirements are tightening globally. Here are the frameworks that matter:
United States
- FinCEN CDD Rule (2016): Requires financial institutions to identify and verify beneficial owners of legal entity customers.
- Corporate Transparency Act (2024): Originally required most US companies to report beneficial ownership information to FinCEN. However, in March 2025, FinCEN issued an interim final rule that removed BOI reporting requirements for all domestic US companies and US persons. As of 2026, only foreign-formed entities registered to do business in the US are required to file. FinCEN is expected to issue a final rule in 2026, so this remains a moving target — firms should maintain clean ownership records in case reporting obligations are reinstated or expanded.
- Bank Secrecy Act (BSA): The foundational US AML law requiring record-keeping and suspicious activity reporting.
European Union
- AMLD4 (2017): Introduced KYB as a formal requirement. Required member states to create national UBO registers.
- AMLD5 (2020): Made UBO registers publicly accessible (later partially reversed by EU Court of Justice ruling in 2022).
- AMLD6 (2024): Expanded predicate offences, increased penalties, strengthened enforcement.
- EU AML Package (2024–2028): A comprehensive overhaul of EU anti-money laundering rules. The new EU Anti-Money Laundering Authority (AMLA) began operations in July 2025 from its headquarters in Frankfurt. The new AML Regulation — which replaces all five existing AML directives with a single, directly applicable rulebook — takes effect on 10 July 2027. AMLA will begin direct supervision of 40 high-risk cross-border financial institutions by 2028. Fines can reach up to 10% of annual turnover or €10 million, whichever is higher.
- MiCA & Crypto AML (2024–2025): The Markets in Crypto-Assets Regulation (MiCA) is now in force. AMLA has flagged the crypto sector as "an immediate priority," requiring crypto-asset service providers to have effective AML/CFT systems from the day of licensing.
United Kingdom
- Money Laundering Regulations 2017: Requires regulated entities to conduct CDD, including UBO identification.
- PSC Register: UK companies must publicly disclose persons with significant control.
Global Standards
FATF Recommendations 24 and 25 set the global standard for beneficial ownership transparency. Updated in 2023 to require countries to ensure timely access to accurate UBO information.
The direction is clear: More transparency, more enforcement, higher penalties for non-compliance. Every major regulatory update in the past five years has expanded KYB obligations.
How to Build a KYB Process
Define Your Risk Appetite
Not every business relationship carries the same risk. Define categories (low, medium, high) based on jurisdiction, industry sector, ownership complexity, transaction volume, and PEP/sanctions exposure.
Collect and Verify Entity Data
For every new business relationship, collect the legal name, registration number, jurisdiction, registered address, date of incorporation, and current status. Verify against official government registries — not self-reported information.
Identify and Verify UBOs
Map the ownership chain to identify all natural persons who qualify as UBOs. Trace through holding companies and intermediate entities. Run KYC checks on each identified UBO.
Screen Against Watchlists
Screen the entity, its UBOs, and its directors against global sanctions lists, PEP databases, and adverse media sources. Document all results with timestamps for audit purposes.
Assess Risk and Decide
Based on collected evidence, assign a risk rating: Approve (low risk), Approve with conditions (medium risk), Escalate (high risk, senior review), or Reject (unacceptable risk).
Monitor Continuously
Set up ongoing monitoring for changes in company status, ownership changes, new sanctions designations, adverse media alerts, and updated financial filings. Review frequency should match the risk level.
Manual vs. Automated KYB
Manual KYB was the standard for decades. Compliance teams would request documents, search government registries one by one, cross-reference data in spreadsheets, and file paper reports. The problem: it does not scale.
✗ Manual KYB
✓ Automated KYB
The shift to automated KYB is not about replacing compliance teams. It is about letting them focus on judgment calls — escalated cases, edge cases, complex structures — instead of data collection. Global Database's KYB API, for example, returns verified entity data, ownership chains, and financial records in a single call — pulling directly from official registries rather than cached databases.
What to Look for in a KYB Solution
Where does the data come from?
The gold standard is first-party data sourced directly from official government registries. Registry-sourced data is verifiable, timestamped, and audit-ready. Third-party data may be outdated, incomplete, or impossible to trace back to its original source. Global Database, for instance, sources 100% of its company records from government registries — covering 600M+ entities with a full audit trail back to the issuing authority.
How many jurisdictions are covered?
If your business operates across borders, you need a provider covering all major regions: North America, Europe, Asia-Pacific, Middle East, Africa, and Latin America.
Does it include ownership and UBO data?
Entity verification alone is not enough. You need the ability to trace ownership chains, identify shareholders, map corporate hierarchies, and pinpoint UBOs — across multiple layers and jurisdictions.
Is financial data included?
Credit scores, financial statements, and filing history provide a critical layer of risk assessment that pure identity verification misses.
Can it integrate into your existing workflow?
API-first solutions let you embed KYB checks directly into onboarding flows, CRM systems, and compliance platforms.
Is there an audit trail?
Every verification should be timestamped, sourced, and documented — ready for regulatory review at any time.
KYB in Practice: Industry Use Cases
Banking & Financial Services
Verify every corporate customer before opening an account. KYB confirms the entity exists, identifies UBOs, screens against sanctions, and assesses credit risk.
Fintech & Payments
Onboard thousands of merchants per month. Automated KYB via API is the only way to verify at this scale without killing conversion rates.
Marketplace Platforms
Verify that sellers are legitimate businesses. KYB prevents fraudulent merchants from operating on the platform and protects from liability.
Supply Chain & Procurement
Verify suppliers before signing contracts. Confirm they are financially stable, legally registered, and not controlled by sanctioned individuals.
- KYB (Know Your Business) is the process of verifying a company's identity, ownership, and risk profile before entering a business relationship.
- It is legally required for banks, fintechs, payment processors, and other regulated entities under AML laws including FinCEN's CDD Rule, EU AMLD, and FATF Recommendations.
- A complete KYB check includes entity verification, UBO identification, sanctions and PEP screening, financial assessment, and ongoing monitoring.
- The regulatory trend is toward more transparency and stricter enforcement. The EU's new AMLA is operational, the AML Regulation takes effect in 2027, and fines can reach 10% of turnover. In the US, the Corporate Transparency Act remains law even as domestic reporting requirements are paused — firms should stay prepared.
- Automated KYB replaces manual processes — reducing verification time from days to seconds and improving accuracy.
- The best KYB solutions source data directly from official government registries, providing verifiable, timestamped records that hold up to regulatory scrutiny.
Frequently Asked Questions
What does KYB stand for?
KYB stands for Know Your Business. It is the process of verifying a company's legal identity, ownership structure, financial health, and risk profile before entering into a business relationship.
What is the difference between KYB and KYC?
KYC (Know Your Customer) verifies individuals — their identity, address, and source of funds. KYB verifies business entities — their registration, ownership chains, UBOs, and financial health. In practice, the two overlap: once you identify a company's UBOs through KYB, you run KYC checks on those individuals.
Is KYB legally required?
Yes, for regulated entities. Banks, fintechs, payment processors, insurance companies, crypto exchanges, and other organizations covered by AML laws are legally required to perform KYB. The specific requirements vary by jurisdiction, but the obligation exists under FinCEN's CDD Rule (US), EU AML Directives, UK Money Laundering Regulations, and FATF Recommendations globally.
How long does a KYB check take?
Manual KYB can take days to weeks depending on the complexity of the ownership structure and the jurisdictions involved. Automated KYB — using an API that connects directly to government registries — can return verified entity data, ownership chains, and financial records in seconds.
What is a UBO?
A UBO (Ultimate Beneficial Owner) is the natural person who ultimately owns or controls a legal entity. Most jurisdictions define a UBO as someone who holds 25% or more of the shares or voting rights, or who exercises control through other means. Identifying UBOs is the most critical — and most complex — part of KYB.
What happens if you skip KYB?
Failing to perform adequate KYB can result in regulatory fines (up to 10% of annual turnover under EU rules), criminal liability for senior officers, loss of banking and payment processing relationships, and severe reputational damage. The root cause of most AML enforcement actions is insufficient verification at onboarding.
What data sources should a KYB check use?
The gold standard is first-party data sourced directly from official government registries — the same authorities that issued the company's registration in the first place. Registry-sourced data is verifiable, timestamped, and audit-ready. Global Database connects to 400+ government registries across 200+ countries for this reason.
