Know Your Business (KYB) verification has moved from a compliance checkbox to a frontline defence against shell companies, sanctioned entities and fraud, and 2026 has raised the stakes considerably.
According to AiPrise, KYB is the process of confirming that a company a bank, FinTech, marketplace or payment platform wants to do business with actually exists, is legally registered, and is controlled by people who are who they claim to be.
Where Know Your Customer (KYC) verifies individuals, KYB verifies the entity and the humans behind it, and the two disciplines overlap by design: a legitimate business controlled by a sanctioned individual is still a regulatory problem.
The obligation is legally binding for regulated financial institutions across major markets. In the US, the Bank Secrecy Act and FinCEN’s Customer Due Diligence Rule require firms to identify and verify beneficial owners holding 25% or more of a legal entity customer. The UK’s Money Laundering Regulations 2017 and the EU’s incoming AMLR, applying from 2027 under the new AMLA supervisor, impose comparable requirements.
The regulatory picture shifted sharply in August 2026, when FinCEN issued a final rule permanently exempting US companies from reporting beneficial ownership information under the Corporate Transparency Act, leaving only foreign companies registered to do business in the US within scope.
The practical effect is that no government database now exists for firms to lean on; verifying who owns a US business has become a task institutions must perform themselves, even as their underlying CDD Rule obligations remain unchanged. If anything, KYB has become more important in the US this year, not less.
A complete KYB check spans five areas: confirming legal existence against registry data, verifying business identity details, tracing ultimate beneficial ownership through however many holding structures separate it from individuals, screening against sanctions and PEP lists, and assessing risk context such as digital footprint.
Programmes are increasingly run as a continuous lifecycle, covering collection, verification, risk scoring, review and ongoing monitoring, rather than a one-off check at onboarding.
The hardest problems remain registry fragmentation across jurisdictions, layered ownership structures designed to obscure UBOs, thin data on small businesses and sole proprietors, and generative AI-enabled fraud capable of manufacturing entire fake businesses, complete with documents, websites and synthetic identities.
Automation is increasingly the answer: straightforward checks can now complete within minutes, freeing analysts to focus on exceptions rather than manual data-gathering.
