Both acronyms come up in every compliance conversation, and they're often used interchangeably. They shouldn't be: KYC verifies people, KYB verifies companies — and most regulated businesses need both.
Know Your Customer is the process of verifying the identity of a natural person: confirming that the passport or ID card is genuine, that the person presenting it is its living owner (liveness and face match), and that they don't appear on sanctions or PEP lists. In most EU member states, KYC is mandatory before a business relationship starts in sectors such as banking, payments, iGaming and crypto.
A modern KYC flow checks the document's security features and machine-readable zone (MRZ), matches a live selfie against the document photo, and screens the verified name against watchlists — ideally in one automated pass of under half a minute.
Know Your Business applies the same principle to legal entities. Before you onboard a company, you need to know it exists, who controls it, and whether its ownership hides risk. That means retrieving registry extracts, verifying registration numbers, and — the hard part — identifying ultimate beneficial owners (UBOs): the natural persons who ultimately own or control the entity, typically at a threshold of 25%.
Every UBO then goes through KYC. This is why KYB is best understood as a superstructure on top of KYC, not an alternative to it.
Manual KYB used to mean days of registry lookups and document chasing. Automated platforms compress this: registry data is retrieved via API, UBO structures are resolved programmatically, and each UBO gets the same 20-second KYC flow as a consumer. The result is that corporate onboarding shrinks from days to minutes, with a complete audit trail as a by-product.
snapID runs KYC and KYB in a single platform: one integration, one dashboard, one audit log — from the first ID scan to ongoing monitoring of the whole relationship.
