Secure verifications for every industry
We provide templated identity verification workflows for common industries and can further design tailored workflows for your specific business.
Today, verifying the identity of customers and businesses has become critical for regulatory compliance, fraud prevention, and trust-building. Two key verification frameworks stand at the center of these efforts: Know Your Customer (KYC) and Know Your Business (KYB). They might sound similar, but understanding KYC vs. KYB – the differences between verifying individuals versus companies – is crucial for any organization. By knowing when to apply each, businesses can improve compliance with anti-money laundering regulations, enhance security, and streamline onboarding.
For organizations navigating the complex landscape of identity verification, grasping the nuances between KYC and KYB can significantly impact operational efficiency and customer experience. This comprehensive guide breaks down what each term means, their core components, key differences, challenges, and best practices. Whether you’re a financial institution or a growing enterprise, learning when to use KYC or KYB (and sometimes both) will help ensure you meet compliance requirements while building trust with clients.
Know Your Customer (KYC) is the process of verifying the identity of individual customers and assessing their potential risk factors. Originally born out of anti-money laundering (AML) regulations in financial services, KYC has since become a standard practice across many industries. Banks, fintech companies, insurers, and other organizations use KYC procedures to ensure they truly know who their customers are. This helps prevent identity theft, fraud, money laundering, and other illicit activities by confirming that a new customer is legitimate and evaluating the risk they might pose.
KYC isn’t just a one-time checkbox at account opening – it’s an ongoing framework. A sound KYC program will not only verify a customer’s identity during onboarding but will also monitor their activity over time. Below are the core components that make up a comprehensive KYC program, followed by common scenarios when KYC is required.
This is the foundation of KYC. CIP involves collecting and verifying basic identifying information from the customer, such as their full legal name, date of birth, residential address, and government-issued identification number (for example, a passport or driver’s license number). Organizations must ensure the documents are valid and belong to the person, establishing that the individual is who they claim to be.
CDD goes beyond simply gathering ID documents. It requires understanding the nature of the customer’s relationship and evaluating their risk level. This includes verifying the authenticity of identification documents, confirming the customer’s physical existence if needed (for instance, through selfie checks or in-person verification), understanding the purpose of the account or transaction (e.g. why they are opening an account or what types of transactions they intend to carry out), and establishing the source of the customer’s funds or wealth. The goal of CDD is to assess how much risk a customer might bring – for example, a politically exposed person (PEP) or someone from a high-risk country might warrant closer scrutiny.
For higher-risk customers, additional scrutiny is applied beyond regular CDD. EDD measures can include more rigorous document verification (collecting multiple forms of ID or corroborating information from independent sources), a deeper investigation into the customer’s source of wealth, and obtaining more detailed information about the customer’s business or occupation. EDD often also involves ongoing monitoring with greater frequency or depth. For instance, transactions of a high-risk client might be reviewed more regularly, and certain activities might require managerial approval. The aim is to ensure that higher-risk customers are not engaging in money laundering, fraud, or other illegal activities under the radar.
Modern KYC programs don’t stop after the initial verification. Once a customer is onboarded, institutions continuously monitor their account and transactional behavior for any red flags or suspicious activities. This ongoing monitoring includes watching transactions for signs of money laundering or fraud, periodically refreshing the customer’s information (e.g. requesting updated ID documents or proof of address on a scheduled cycle or when triggers occur), and screening the customer against updated sanctions lists or watchlists (such as those for terrorists or sanctioned individuals). Continuous monitoring ensures that the customer’s risk profile is kept up-to-date and that the institution can catch any unusual behavior early.
KYC procedures are essential in a variety of situations where individuals are involved. Businesses must conduct KYC in the following scenarios (among others):
Whenever a person opens a bank account, investment account, insurance policy, or even a cryptocurrency exchange account, the service provider must verify the customer’s identity and background per KYC requirements. This applies across banking, securities, crypto platforms, etc.
Any time a service is provided that falls under Anti-Money Laundering regulations, KYC checks are required. For example, remittance services, currency exchanges, payday lenders, and other financial services must perform KYC on their clients as mandated by regulators.
High-value or high-risk transactions: If an individual is engaging in a large transaction (for instance, buying a high-value asset or transferring a large sum of money), the institution will perform KYC checks to ensure the funds are legitimate and the person isn’t using the transaction to launder money. This might include verifying the source of funds for a large wire transfer or cash deposit.
Age-restricted products or services: When selling products/services that have age restrictions (like alcohol sales, gambling services, certain pharmaceuticals, etc.), companies use KYC to verify the customer’s age and identity. This prevents minors or unauthorized persons from accessing these services.
Industries with customer verification requirements: Sectors such as gambling, healthcare, telecommunications, and aviation (among others) often have specific KYC or customer verification rules. For example, a telecom company may need to verify the identity of a person purchasing a SIM card in certain countries to prevent fraud and crime. Anytime an industry has know-your-customer mandates, organizations in that space must implement KYC.
Identity verification for individual customers is the heart of KYC compliance. Businesses typically require official documents (like a passport, ID card, or driver’s license) to confirm a new customer’s identity and ensure they are who they claim to be under Know Your Customer regulations.
With KYC processes in place, organizations can confidently onboard customers knowing they have verified their identities and assessed their risks. Next, we’ll look at KYB, which applies similar principles to businesses instead of individuals.
Know Your Business (KYB) is the business-focused counterpart to KYC, concentrating on verifying the identity, legitimacy, and risk profile of corporate entities. Instead of individuals, KYB is all about due diligence on companies, organizations, and other businesses you might be entering into a relationship with. As business-to-business transactions increasingly move online and global supply chains become more complex, KYB has become essential for companies to avoid partnering with fraudulent or non-compliant businesses.
Just like KYC aims to establish trust with individual customers, KYB aims to establish trust between businesses. When a company opens an account with a bank, signs a contract with a supplier, or partners with another firm, KYB processes assure that the company is legitimate, legally registered, and not a front for illicit activities. KYB also involves identifying the people who ultimately own or control the business (often called beneficial owners or UBOs) because those individuals’ backgrounds can pose risks as well. In many jurisdictions, KYB checks are required by law for financial institutions and other regulated industries as part of their AML compliance when dealing with business clients.
KYB can be more complex than KYC because businesses might have multi-layered ownership structures, international offices, and various regulatory obligations. Below we break down the core components of KYB and when organizations need to conduct KYB checks.
KYB procedures are necessary whenever an organization is entering into relationships or transactions with other businesses. Key scenarios include:
By conducting KYB in these situations, organizations protect themselves from inadvertently facilitating financial crimes or getting entangled with fraudulent companies. KYB checks provide a layer of assurance that your business counterparties are who they claim to be and operate above board.
While KYC and KYB share the common goal of managing risk and ensuring compliance, they differ in several important ways. Below are the key differences between Know Your Customer and Know Your Business:
KYC is focused on verifying individual people (natural persons). The subject of KYC is an individual customer – for example, John Doe opening a bank account. KYB, on the other hand, targets legal entities (businesses such as corporations, LLCs, partnerships, charities, etc.). The subject of KYB is the company or organization itself. In short: KYC = verifying a person, whereas KYB = verifying a company (and its associated persons).
Performing KYC on an individual is often more straightforward than performing KYB on a business. An individual typically has a single identity and a limited number of documents. KYC procedures involve collecting a person’s ID and maybe one or two proof documents. In contrast, KYB can require navigating complex ownership structures. A business might have layers of subsidiaries, holding companies, or multiple owners. It might operate in several jurisdictions. Verifying a business could mean identifying all major shareholders across different countries, which is inherently more complex and time-consuming than verifying one person.
Because of the subject difference, the documents needed for KYC vs KYB differ greatly. KYC generally relies on personal identification documents: government-issued IDs (like a passport, national ID card, or driver’s license), proof of address documents (utility bills, etc.), and possibly things like a selfie or biometric verification. KYB requires business documentation: for example, a certificate of incorporation or business registration document, articles of association, corporate bylaws, business licenses, shareholder registers, and financial statements. Essentially, KYC asks for “Who are you as a person?” while KYB asks “Show me your company’s papers and structure.”
Related to complexity, KYC usually involves verifying one individual or a few individuals (like a joint account). Once you’ve checked the person’s ID and perhaps run a background check, you’re done apart from ongoing monitoring. KYB, however, often means verifying multiple people and entities within a corporate structure. For example, if a corporation has three owners who each own 30%, you need to verify each of those owners (KYC on the owners as part of KYB on the business). You also verify the business entity itself. So KYB has multiple layers: verify the business + verify the UBOs + sometimes verify directors or executives. It’s a multi-pronged process, whereas KYC is typically one-dimensional (just the customer).
KYC regulations have been around for decades and are relatively standardized across many jurisdictions. Most countries have clear rules for customer identification as part of AML laws, and international bodies like the Financial Action Task Force (FATF) provide guidelines that many follow. KYB requirements, in contrast, have been evolving and can vary significantly between countries and industries. Some countries only recently expanded their AML laws to cover due diligence on businesses (and the requirements can differ on thresholds for ownership, etc.). Additionally, certain sectors might have extra KYB requirements (for instance, fintech or crypto companies might face stricter KYB rules for onboarding corporate clients). In summary, KYC is governed by mature, widely adopted rules, while KYB’s regulatory landscape is a bit more patchwork and still solidifying globally.
Because individuals generally have stable identities (your name and DOB don’t change often), KYC updates often follow a risk-based approach – higher-risk customers get reviewed more frequently, but many customers might only be re-verified every few years or if a trigger event occurs. Businesses, however, can undergo changes more frequently (new ownership, mergers, changing directors, etc.). KYB thus typically requires more frequent updates and monitoring. A company that was low-risk last year could acquire a new owner this year who changes its risk profile. Therefore, institutions often schedule more frequent KYB reviews or even use continuous monitoring tools for their business clients, whereas for personal clients the updates might be less frequent (unless risk factors change).
In essence, KYC focuses on individuals with relatively straightforward verification, while KYB deals with entities and can involve digging through more complex information. Both are essential, but they require different approaches and expertise.
Implementing KYC and KYB processes can be challenging due to practical and regulatory issues. Organizations must balance thorough compliance with efficiency and user experience. Here are some common challenges for each:
Many businesses, especially large or international ones, have complicated ownership hierarchies. Identifying the ultimate beneficial owners in a company with layers of subsidiaries or shell companies is challenging. Bad actors might deliberately create convoluted structures across multiple jurisdictions to hide true owners. Unraveling these to find who is really in control can be time-consuming and sometimes impossible if certain countries don’t share ownership information.
In some countries or regions, public information about companies is scarce. Not all jurisdictions have easily searchable online business registries. Even when they do, the information may not be up-to-date or verified. This makes it hard to obtain reliable data for KYB. For example, trying to verify a small business in a country without a public registry might require on-the-ground verification or reliance on third-party databases that could be incomplete.
There’s no single global standard for KYB documentation. Each country has its own incorporation documents and certificates, often in different languages and formats. Moreover, what’s considered acceptable proof of address or ownership might differ. This lack of standardization means KYB teams need broad expertise and may need local knowledge or partners to interpret foreign documents. It also means developing a one-size-fits-all KYB process is difficult, as you must account for various norms and standards.
For institutions dealing with many business clients, continuously monitoring each one for changes is tough. If a client base includes thousands of companies, keeping track of each company’s periodic filings, management changes, or news mentions becomes a big data problem. Automation can help (with alerts for changes in registry data or adverse media hits), but setting up these systems and ensuring they remain accurate is a challenge. Companies also change rapidly – mergers, acquisitions, or closures can happen frequently – and the KYB process must catch these events and reassess the relationship promptly.
In many real-world scenarios, organizations need to implement both KYC and KYB in tandem. This is especially true in B2B contexts where you must verify a business and the individuals behind that business. Here are common situations where both KYC and KYB processes come into play:
When a business opens an account with a bank or financial institution, the bank needs to vet the company as well as the people associated with it. In practice, the institution will conduct KYB on the business entity (to verify the company’s legitimacy, registration, and financial standing) and perform KYC on the key individuals – such as the beneficial owners, authorized signatories, and principal controllers of that business. For example, if “ABC Corp” wants to open a bank account, the bank will verify ABC Corp’s registration details and also verify John and Jane who own and control ABC Corp.
Online platforms that connect buyers and sellers who are businesses (like wholesale marketplaces or services connecting freelancers to companies) must employ both KYB and KYC. They apply KYB to verify each business seller or buyer on the platform (ensuring each company is legitimate and not fraudulent) and use KYC to verify the individuals representing those businesses. This dual approach maintains trust in the marketplace – the companies are real and the users who act on behalf of those companies are verified persons.
Enterprises that manage complex supply chains or work with many third-party vendors need both KYB and KYC as part of their due diligence. For each corporate supplier or partner, KYB is performed to confirm the company’s legitimacy, compliance (for instance, that it’s not owned by a sanctioned entity), and reliability. Additionally, companies often conduct KYC on key individuals within high-risk supplier organizations – for example, verifying the identity and background of a supplier’s owner or on-site managers if the relationship is sensitive. This combination helps prevent issues like supplier fraud, conflicts of interest, or unwittingly doing business with a company run by bad actors.
Banks that offer commercial services (loans, trade finance, corporate credit cards, etc.) and other B2B service providers will complete KYB on the client company and KYC on the individuals with authority or significant control. For instance, a bank providing a line of credit to a company will verify the business’s financials and registration (KYB) and also verify the CEO, CFO, or any guarantors for that credit line (KYC). In sectors like corporate insurance or enterprise software, sales due diligence might include KYB on the client company and KYC on the executives signing the contract. Ensuring both the company and its representatives check out is just good practice whenever large contracts or financial relationships are on the line.
Trusted B2B relationships require KYB checks on the company and KYC checks on its owners or representatives. For example, when two companies form a partnership or a bank onboards a business client, both the business’s credentials and the personal identities of key stakeholders need verification.
The above scenarios illustrate that KYC and KYB are not mutually exclusive – they often work hand-in-hand. A robust compliance program will assess the entity and the individual side of every relationship. If you only did KYB on a company and ignored who owns it, you could miss that the owner is a known criminal. Conversely, if you only did KYC on an individual representative and not the company, you might miss that the company itself is shell with no valid business operations. Using both gives a full picture.
Whether you’re implementing KYC, KYB, or a combination of both, following best practices can improve effectiveness and efficiency. Here are some strategies to get the most out of your compliance program while keeping it user-friendly:
Not every customer or business presents the same level of risk, so your verification efforts should be proportional to the risk level. Tailor the depth and frequency of verification based on risk profiles. High-risk relationships (say, a customer from a high-corruption-risk country or a business in a high-money-laundering-risk industry) should face more rigorous checks and more frequent reviews. This might mean additional identity documents, more detailed questioning, and continuous transaction monitoring for those cases. Lower-risk customers (perhaps a local salaried employee with a small account) can be onboarded through a simpler process with basic ID verification and less frequent updates. Adjusting the monitoring frequency is also key – for example, perform annual reviews for medium-risk clients but maybe semi-annual for the highest risk, and perhaps only once every few years for the lowest risk. This risk-based approach is encouraged by regulators and allows you to focus resources where they matter most.
Leverage modern technology to streamline and strengthen your KYC/KYB processes. Advanced tools like AI and machine learning can assist in document verification (automatically detecting fake IDs or altered documents) and in risk scoring (flagging anomalous patterns in transaction data). API integrations with reliable data sources (like government ID databases, business registries, or credit bureaus) enable real-time verification of information. Some organizations are even exploring blockchain solutions to create immutable records of identity verification that can be securely shared, reducing duplication of efforts. Additionally, using automated screening software can continuously scan sanctions lists, watchlists, and news feeds for any mention of your customer or business partner, alerting you instantly to new risks. By integrating these technologies, you improve accuracy (reducing human error), speed up the process (reducing manual paperwork), and can handle larger volumes of verifications efficiently.
Compliance doesn’t have to come at the expense of customer or client experience. In fact, a smoother process can improve compliance because users are more likely to complete it truthfully. To achieve this, design your verification workflow with the user in mind. One approach is progressive or tiered verification: start by asking for the minimum information needed, and only escalate to more detailed checks if risk factors are detected. For example, an online platform might initially just ask for basic info and an ID upload; if something looks suspicious or the account engages in higher-risk activity, then require additional documents or checks. Always provide clear guidance on what information or documents are required and why – users are more cooperative when they understand the purpose. Offering multiple options can also help (for instance, allow either a driver’s license or a passport as ID, allow verification via a phone app or in-person at a branch, etc.). Finally, ensure the process is mobile-friendly and accessible since many customers will complete KYC on their smartphones. A well-thought-out UX reduces drop-offs and errors, making your compliance stronger and your customers happier.
Handling the sensitive data collected in KYC/KYB is a huge responsibility. It’s vital to develop a comprehensive data management strategy. This includes clear data retention policies – know what data you need to keep and for how long (as required by law or business needs), and just as importantly, know when to securely dispose of data that’s no longer needed. Implement strong data security measures to protect this information: encrypt stored data, use secure transmission methods, and restrict access only to personnel who need it.
Compliance with privacy regulations is non-negotiable: ensure your processes meet the requirements of laws like GDPR, CCPA, and any other local privacy laws (which may dictate, for example, getting customer consent for data processing or honoring rights to delete data). Also plan for regular data maintenance – verification data can become outdated, so have processes to update information periodically (e.g., ask customers to refresh their ID document on file every few years, or update a business client’s registry info annually). A solid data strategy not only keeps you compliant but also builds customer trust that their personal or business information is being handled carefully.
KYC and KYB efforts touch multiple parts of an organization – compliance teams set the rules, operations teams execute the checks, the sales or customer-facing teams interact with clients, and IT teams manage the tools. Breaking down silos between these departments is essential. Encourage regular communication and training so that, for example, the sales team understands why certain documents are required and can explain it to clients, or the compliance team listens to feedback from customer-facing staff about where clients struggle in the process. Align all departments on common goals and Key Performance Indicators (KPIs) for verification (such as turnaround time for onboarding, or reduction in compliance findings).
Develop feedback loops: if the operations team notices a pattern of false positives in fraud flags, they should feed that back to the risk modelers to adjust. If customers keep asking the support team similar questions about the ID upload step, that might indicate the instructions need improvement. By collaborating, the organization ensures that KYC/KYB standards are applied consistently and any process frictions are quickly identified and resolved. A culture of compliance that spans all relevant teams will always outperform a siloed approach.
The world of identity verification is continuously evolving, driven by technological innovation and shifting regulatory expectations. Several emerging trends are shaping the future of both KYC and KYB, promising to make these processes more secure and efficient in the coming years:
Traditionally, individuals and businesses have had to repeatedly submit copies of the same identity documents to every institution they deal with. Decentralized identity models aim to change that by giving control of identity credentials back to the user. Using blockchain and distributed ledger technologies, people and companies could maintain verifiable credentials (like a proof of ID or incorporation) in a secure digital wallet. They can then share proof of identity with a service provider without exposing all the underlying personal or corporate data. For example, instead of giving a bank a copy of your entire passport, you could provide a cryptographic proof that a government authority verified your identity and age. Blockchain-based systems would allow third parties to confirm that proof is legitimate (signed by the authority) and unaltered, all while your detailed data stays in your possession. Such self-sovereign identity frameworks and verifiable credentials could greatly reduce redundant data sharing and enhance privacy. Moreover, once an identity or business verification is recorded immutably on a ledger, other institutions could rely on that record, potentially creating a “verify once, use many times” scenario. This trend could revolutionize KYC/KYB by making the process more secure (harder to forge blockchain-recorded credentials) and user-friendly (control over one’s own identity info).
Regulators and institutions are moving away from point-in-time verifications (where you verify a customer or business once a year, for example) toward continuous monitoring – sometimes called perpetual KYC. Rather than periodic refreshes that might miss something in between, technology now allows for real-time tracking of certain risk indicators. For instance, if a customer’s transaction patterns suddenly change drastically, an automated system can flag it immediately rather than waiting for an annual review. If a company’s director is added to a sanctions list, the bank can be alerted right away. Real-time risk assessment uses streams of data and analytics to keep an up-to-date risk profile for clients. And when something significant changes – say a business client undergoes a merger or an individual client has a legal name change – the system can trigger an immediate review or enhanced due diligence process rather than waiting. This always-on approach means issues are caught and addressed promptly, but it also requires robust data infrastructure and careful tuning to avoid false alarms. Over time, as data integration improves, expect more institutions to adopt ongoing KYC/KYB monitoring embedded into the customer relationship lifecycle.
There is a growing recognition that the patchwork of KYC and KYB standards across countries creates inefficiencies and loopholes. International bodies and industry groups are pushing for greater standardization in how identity verification is done. We may see progress toward harmonized regulations – for example, more countries agreeing on common definitions of beneficial ownership and requirements to disclose it. Initiatives for a global digital ID (for individuals) or global business identifier numbers could simplify cross-border verification. Additionally, countries are sharing more data with each other (through information-sharing agreements or centralized databases for things like passport verification or company ownership). As these standards align, businesses will benefit from more interoperable verification systems – meaning a verification done in one jurisdiction could be more easily passported or accepted in another. This reduces the compliance burden on multi-national organizations and closes gaps that criminals might exploit between regulatory regimes. In the next few years, we might not get a single global KYC rulebook, but trends like the Financial Action Task Force’s guidance and EU’s evolving AML directives indicate movement toward consistency and collective frameworks.
Emerging technologies are addressing the challenge of verifying identity and other information without unnecessarily exposing sensitive data. One such technology is zero-knowledge proofs (ZKPs), which allow one party to prove to another that a certain statement is true without revealing the underlying information. For example, a zero-knowledge proof could let a user prove “I am over 18 years old” to a verifier without revealing their exact date of birth or any other personal details. In KYC terms, this is revolutionary: it means a company could fulfill an age verification or income verification requirement by checking a cryptographic proof rather than storing a copy of someone’s documents. Beyond ZKPs, other privacy-enhancing technologies like homomorphic encryption (performing computations on encrypted data) or secure multi-party computation can allow institutions to cross-check customer data against blacklists or databases without exposing the data to those database owners. The use of decentralized data storage (as mentioned in decentralized identity) also ensures there isn’t one big honeypot of sensitive info sitting on a server – instead, data can be stored in a distributed way, reducing the risk of large-scale breaches. Overall, the future is pointing toward ways to meet KYC/KYB objectives while minimizing data collection and exposure, which benefits both businesses (less data to secure, less liability) and customers (more privacy).
Understanding the differences between KYC and KYB – and implementing both effectively – is more than just a compliance exercise. In fact, organizations that build sophisticated, efficient verification capabilities can turn compliance into a competitive advantage. Here’s how a strong KYC/KYB program can benefit a business beyond simply avoiding fines:
By accurately identifying customers and business partners and assessing their risks, a company is far less likely to onboard bad actors. This means fewer fraud losses, less chance of facilitating money laundering, and a safer financial environment. In industries like fintech or e-commerce, being known as a platform with low fraud can attract more customers and partners.
By approaching identity verification strategically, organizations can transform what might be seen only as a “regulatory burden” into a valuable business capability. Effective KYC and KYB implementation supports growth, builds trust with customers and partners, and enables innovation in an increasingly digital and interconnected economy. Compliance and customer experience go hand in hand when done right.
Whether you’re setting up verification processes for the first time or enhancing an existing program, understanding the distinct requirements of KYC and KYB is essential. With the right approach, you’ll create effective, compliant, and customer-friendly verification workflows that not only satisfy regulators but also foster confidence and loyalty among your user base.
