Onboard a Corporate Customer with KYB and UBO Verification

Onboarding a corporate customer requires more than verifying the company name — you need to confirm the business is legitimately registered, identify who controls it, and screen those individuals for sanctions, PEP exposure, and adverse media. Youverify handles all of this through a single entity-centric model: the business entity carries its ownership graph, and each UBO can be promoted to its own entity for full KYC and AML treatment. This guide walks you through creating a business entity, triggering a KYB registry check, screening the business and its UBOs for AML risks, and linking verified UBO entities back to the parent business.

Prerequisites

A Youverify account at cowork.youverify.co
Your API secret key from the dashboard under Settings → API Keys
The business’s registered name, registration number, and country of incorporation

Supported countries for KYB

KYB registry checks are available for Nigeria, Kenya, South Africa, and Côte d’Ivoire, with additional countries available via the global business verification endpoint. Contact your Youverify account team or consult the dashboard for the complete, up-to-date list.

Steps

What happens in the background

The moment you create the business entity, Youverify automatically runs a company-level AML screen. The explicit KYB and UBO calls are deliberate steps you control:

KYB check types

`checkType`	What it returns
`basic`	Company name, registration number, status, registration date
`standard`	Basic + directors, entity type, nature of business
`premium`	Standard + UBO ownership graph (where registry provides it)

What’s next

Run AML screening on individual UBO entities
Review the KYB API reference for all available parameters
Read the Entity 360 to understand the ownership graph and how to traverse it
Set up webhooks to receive KYB completion and AML signal events
