--- title: "What is KYB? Know Your Business verification explained" description: "KYB verifies a company's legal existence, ownership, and control before it can transact. What it checks, who counts as a beneficial owner, and how it differs from KYC." date: "2026-09-01" author: "BlindPay Team" updated: "2026-09-01" category: "compliance" faq: - q: "What does KYB stand for?" a: "Know Your Business. It is the process of verifying a company's legal existence, ownership structure, and the individuals who own or control it before that company is allowed to open an account or transact." - q: "What is a beneficial owner?" a: "Under FinCEN's rule, an individual who directly or indirectly owns 25 percent or more of a legal entity's equity, or who controls and directs it, such as a CEO or managing member. A company can have several beneficial owners." - q: "How is KYB different from KYC?" a: "KYC verifies an individual person. KYB verifies a company, and then applies KYC-style checks to the individuals who own or control that company. A business account almost always requires both." - q: "How long does KYB take?" a: "With registry data available and clean documents, minutes to same-day. It slows down for entities with layered ownership, trusts, or jurisdictions where corporate registries are not digitized, sometimes taking days." --- KYB, Know Your Business, verifies that a company legally exists, confirms who owns and controls it, and screens those individuals before the company is allowed to send or receive money. It is the business-side counterpart to KYC: a payment provider cannot know whether it is safe to pay a company without first knowing who actually stands behind it. KYB exists because a shell company is an easy way to hide who is really moving money. A registered business name and a bank account look legitimate on the surface; the ownership and control behind them are where risk actually lives, which is why regulators require providers to look past the entity to the humans running it. ## What does KYB actually verify? A complete KYB check covers four layers: - **Legal existence.** Confirming the company is registered, active, and in good standing with the relevant corporate registry, not dissolved or dormant. - **Ownership structure.** Mapping who owns what percentage of the company, including through holding companies or trusts, until it reaches actual people. - **Beneficial owners.** Identifying and verifying the individuals who meet the ownership or control threshold, then running standard identity and sanctions checks on each of them. - **Business activity.** Confirming the company's stated business matches what it actually does, since a mismatch between registered activity and real transaction patterns is a common fraud and money laundering signal. Skipping any layer leaves a gap. A provider that checks only registration, without tracing ownership to real people, can end up doing business with a company controlled by someone on a sanctions list. ## Who counts as a beneficial owner? The clearest definition comes from FinCEN's Customer Due Diligence rule, built on two prongs. The ownership prong: any individual who, "directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, owns 25 percent or more of the equity interests of a legal entity customer." The control prong: at least one individual with "significant responsibility to control, manage, or direct" the entity, such as a CEO, CFO, or managing member, regardless of ownership percentage. Full detail is in [31 CFR 1010.230(d)](https://www.ecfr.gov/current/title-31/subtitle-B/chapter-X/part-1010/subpart-C/section-1010.230). That two-prong structure exists because ownership alone misses control. A company can be owned by a diffuse group of investors, none crossing 25 percent, while one individual runs every decision. The control prong catches that person even when the ownership math would not. ## How is KYB different from KYC? KYC (Know Your Customer) verifies one individual: identity documents, address, and screening against sanctions and watchlists. KYB verifies a legal entity and then applies KYC to the people who own or control it. Opening a business account almost always triggers both: KYB on the company, KYC on each beneficial owner and often on signers and directors too. The practical difference shows up in documentation. KYC needs a passport or ID and a selfie. KYB needs incorporation documents, a certificate of good standing, an ownership chart, and identity documents for every beneficial owner identified along the way, which is why KYB usually takes longer and involves more back-and-forth than an individual signup. ## When does a payments company require KYB? Any time a business, not an individual, is the account holder or the counterparty receiving payment above a threshold set by the provider's risk policy. Marketplaces onboarding seller accounts, platforms paying out to vendor companies rather than individual contractors, and any B2B cross-border payment all trigger KYB somewhere in the flow. Our [stablecoin payments guide](/resources/more/stablecoin-payments-guide) covers where compliance checks like KYB sit inside a payout flow, and the broader VASP licensing context that requires programs like this is in [what is a VASP](/resources/more/what-is-a-vasp). Requirements also shift as rules like MiCA and the GENIUS Act take effect, tracked in our [regulation tracker](/resources/more/stablecoin-regulation-tracker-2026). ## How does BlindPay fit in? [BlindPay](/global-payments) runs KYB on every business account before it can send or receive a payout: entity verification, ownership mapping, beneficial owner screening, and sanctions checks, built into the same API used to move USDC and USDT over local rails like Pix and SPEI. The [compliance page](/compliance) covers the full program, and the [resources hub](/resources/more) has more on how the pieces fit together, including [what a stablecoin API does](/resources/more/what-is-a-stablecoin-api) end to end. *This article is for general information only and is not legal, tax, or financial advice.*
