Doing business online has never been easier. Companies can onboard customers, suppliers, merchants, and partners across borders without ever meeting face to face.

But that convenience creates a fundamental challenge: how do you know the business on the other side of the transaction is legitimate?

A professional website and convincing company name are no longer enough. Fraudsters can create shell companies, impersonate legitimate businesses, falsify company information, and hide the individuals who ultimately own or control an organization. This makes business verification an increasingly important part of onboarding and risk management.

For organizations operating in regulated or higher-risk sectors, this process is commonly formalized through Know Your Business (KYB) procedures. KYB helps organizations verify that a company exists, understand who owns and controls it, identify potential risk indicators, and make more informed onboarding decisions.

What does it mean to verify a business?

Business verification is the process of confirming that a company is legitimate and that the information it provides is accurate. At its simplest, this can involve checking a company’s legal name, registration number, address, and registration status against an official business registry. 

Know Your Business, or KYB, goes further. It refers to the processes organizations use to verify the identity, legitimacy, ownership, and potential risk of businesses they establish relationships with: who owns and controls the company, who its ultimate beneficial owners (UBOs) are, whether those people are who they claim to be, and whether the company or anyone linked to it appears on sanctions lists, is a politically exposed person (PEP), or is linked to adverse media.

It shares many principles with Know Your Customer (KYC). KYC focuses primarily on identifying an individual customer. KYB focuses on understanding a legal entity and the people behind it.

The objective is not simply to establish that a company name appears in a database. Organizations need enough reliable information to understand who they are actually doing business with.

Why business verification matters

Corporate structures can disguise fraud and financial crime. A fraudulent business may attempt to impersonate a legitimate organization. A shell company can obscure the movement or ownership of funds. Complex ownership structures can also make it difficult to determine who ultimately controls a business. Business verification helps organizations identify these risks before establishing or expanding a commercial relationship.

Effective KYB processes can support organizations in several areas.

Fraud prevention

Verifying company information against reliable data sources can expose inconsistencies between what a business claims and what official records show.

For example, an organization might provide a company name or registration number that does not match registry information.

Regulatory compliance

Organizations subject to anti-money laundering (AML) and counter-terrorist financing requirements may need to conduct due diligence on business customers and understand their ownership structures. Exact requirements vary by jurisdiction, industry, and risk.

Risk management

Not every business relationship carries the same level of risk. Understanding a company’s ownership, status, jurisdiction, and associated individuals lets organizations apply a risk-based approach and decide whether additional due diligence is appropriate.

 Faster, more efficient onboarding

Automating business verification can also make onboarding more efficient. Instead of asking compliance teams to manually search multiple registries and databases, organizations can collect and check information as part of a structured digital workflow. Where information or supporting documents are missing, the business itself can be asked to provide them directly, reducing back-and-forth between compliance teams and applicants.

How to check whether a company is legitimate

No single piece of information establishes whether a company is trustworthy. Instead, businesses should consider multiple data points.

To make this concrete, imagine an online marketplace onboarding a new third-party seller: a company that wants to sell consumer electronics on the platform and receive payouts from its sales. Before the seller can list products, the marketplace needs to know who it is dealing with. We’ll follow it through each step.

1. Check company registration information and status

One of the first steps is confirming that the company exists in an appropriate official or trusted registry. Depending on the jurisdiction, useful information can include:

• Registered company name
• Registration number
• Incorporation date
• Registered address
• Current company status
• Company type
• Directors or officers

The information provided by the company should correspond with the information available from authoritative sources. Discrepancies do not automatically indicate fraud, but they may warrant further investigation.

Finding a company in a registry is only the beginning. Organizations should also determine whether the entity is active and in good standing where that information is available. A company may exist in historical records but have subsequently been dissolved, deregistered, or become inactive.

In our example, the registry confirms the seller’s name and registration number, shows that it is active, and lists two directors. It also shows that the company was incorporated eight months ago, although its seller profile says it has been trading “for over a decade”. That doesn’t prove anything on its own, but it is worth noting.

2. Understand the ownership structure and identify the ultimate beneficial owners

Business ownership can become complicated quickly. A company’s shareholders may be individuals, but they may also be other companies. This makes it important to understand not only the immediate shareholders but also the natural persons who ultimately own or control the organization. These individuals are commonly known as ultimate beneficial owners.

An ultimate beneficial owner (UBO) is the individual who ultimately owns or controls a legal entity. The precise definition and ownership thresholds can differ between jurisdictions, although a common threshold is ownership or control of 20% or more. Identifying UBOs is an important part of KYB because the shareholders listed for a company are not always the people who ultimately benefit from or control the business.

Depending on the jurisdiction, UBO information may be available directly from the business registry. Where it isn’t, the business can be asked to declare its UBOs as part of the onboarding process.

The seller’s registry record lists two shareholders: one of its directors, with 40%, and a holding company, with 60%. A company can’t be a UBO, so the marketplace asks the seller to declare the individuals who ultimately own or control it during onboarding. The seller declares one UBO.

3. Verify directors, shareholders, and UBOs

Knowing someone’s name is different from knowing who that person actually is. Once the relevant individuals behind a company have been identified, organizations may need to verify their identities.

Identity verification (IDV) can help establish that directors, shareholders, UBOs, or other relevant representatives are genuine people and that the identity information they provide is authentic. This is where KYB and KYC increasingly intersect.

The seller’s two directors and its declared UBO each complete an identity verification check, confirming that each is a genuine person whose details match what the seller declared. This also helps the marketplace make sure the people setting up the account are not using someone else’s identity to get onto the platform.

4. Screen businesses and associated individuals

Business verification can also involve checking companies and relevant individuals against sanctions, politically exposed persons (PEP), adverse media, and other applicable AML data sources. For example, a company may appear legitimate in a business registry while one of its beneficial owners presents additional risk that requires further investigation.

A potential screening match does not necessarily mean that a company or individual is involved in financial crime. Organizations need processes to investigate potential matches, resolve false positives, and determine whether additional due diligence is appropriate. Connecting business verification with identity verification and AML screening can give compliance teams a more complete picture of the relationship.

Screening returns a potential PEP match for the declared UBO. An analyst on the marketplace’s trust and safety team reviews it, finds that it relates to a different person with a similar name, and resolves it as a false positive.

5. Put it together: look for inconsistencies and fraud signals

Business verification is not simply about checking individual data points. Organizations should also consider whether the information they collect makes sense when viewed together. Potential warning signs can include:

• Company information that does not match registry records
• Registration numbers associated with a different company
• Recently incorporated businesses presenting themselves as long-established organizations
•  Ownership information that is unexpected, unclear, or incomplete
• Individuals whose information cannot be reliably verified
• Discrepancies between declared and identified beneficial owners
• Relevant sanctions or AML screening matches

A risk indicator does not automatically establish that a business is fraudulent. Instead, it can provide a reason to investigate further or apply enhanced due diligence.

Taken together, most of the seller’s picture is consistent: an active company, verified directors and UBO, and no confirmed screening matches.

The open question is the gap between its recent incorporation date and its claim to be long established. Before letting the seller go live, the marketplace asks it to explain the gap, for example by providing supporting documents through the onboarding flow, and reviews the answer. The exact process will depend on the organization’s industry, jurisdiction, regulatory obligations, and risk appetite.

Manual business verification vs. automated KYB

Some elements of business verification can be performed manually. Compliance teams can search corporate registries, review company documents, identify shareholders and directors, and conduct additional checks on the individuals involved. This may work when onboarding a small number of businesses. At scale, however, the process can quickly become resource-intensive.

Organizations operating across multiple markets may need to work with different registries, data formats, languages, corporate structures, and regulatory requirements. Compliance teams can also spend significant time moving between systems and manually reviewing information. Automated KYB can bring these checks into a more structured workflow. 

Depending on the solution and available data, automation can retrieve company and beneficial ownership information from relevant sources, verify registration details and the identities of the people involved, run AML screening, and collect missing information and documents directly from the business. Bringing these results together in one place, with the source of each data point shown, also makes inconsistencies easier to spot and review.

Automation does not remove the need for compliance judgment. Instead, it can reduce repetitive manual work and help teams focus their attention on higher-risk or ambiguous cases.

Business verification should not always end at onboarding

A company that passes verification today may change tomorrow. Directors can change. Ownership can be transferred. New beneficial owners can appear. A business can change status, and individuals associated with the organization may subsequently appear on sanctions or other relevant AML lists.

For organizations that need to manage risk throughout the customer lifecycle, relying exclusively on information collected during initial onboarding can therefore create gaps. Depending on applicable requirements and the organization’s risk-based approach, re-verifying businesses at regular intervals can help identify changes to company details and ownership, while ongoing AML monitoring can flag new sanctions, PEP, or adverse media matches between those checks and trigger a reassessment when necessary.

For the marketplace, that might mean re-verifying the seller once a year and monitoring its directors and UBO for new AML risks in the meantime.

This turns KYB from a one-time onboarding check into an ongoing approach to understanding business relationships.

How Veriff supports business verification

Business verification becomes more powerful when organizations can connect company data with verification of the people behind the business. Veriff’s Business Verification solution helps organizations verify businesses across 300+ jurisdictions as part of a digital KYB workflow, reducing the need to manually collect and cross-check company information across multiple sources.

Organizations can use Veriff to support processes such as:

• Verifying business information against business registries and trusted data sources, with the source of each data point shown
• Identifying company directors and shareholders
• Retrieving beneficial ownership information from registries where available, or collecting it from the business
• Verifying the identities of people associated with a business
• Screening relevant individuals and businesses against sanctions, PEP, and adverse media lists, with optional daily AML monitoring 
• Letting the business provide missing information, UBOs, and documents itself through a guided onboarding flow
• Supporting risk-based business onboarding, with results, comments, and a full audit trail kept in one case

Combining Business Verification with identity verification can help organizations answer two fundamental questions: Is this a legitimate business, and are the people behind it who they claim to be?

From checking a company to knowing your business

Determining whether a business is legitimate requires more than finding its website, checking reviews, or confirming that its name appears in a company registry. Organizations need to understand the legal entity, its status, its ownership structure, and the people who ultimately control it. Depending on their regulatory obligations and risk exposure, they may also need to screen relevant parties and re-check them over time. That’s the difference between simply checking a company and conducting effective Know Your Business.

By bringing business data, ownership information, identity verification, and risk screening into a connected workflow, organizations can make more informed onboarding decisions while reducing the manual burden on compliance teams.
