# KYC Platform

> Noah verifies identity through Sumsub and can accept pre-existing KYC under triparty agreements, so a partner's customer is not reverified.

## Overview

Noah integrates with identity verification service [Sumsub](https://sumsub.com) to enable KYC data sharing through triparty agreements. Noah allows clients to share pre-existing KYC data, avoiding duplicate verification processes for customers already verified with partner organizations.

:::info
Additional KYC applications for users who have already completed KYC will be rejected. Sumsub flags duplicate applications as a fraud prevention measure. If a user has already completed KYC, do not initiate another KYC session. Instead, retrieve the user's existing verification status.

## Sumsub Token Share

The integration uses a Sumsub token share to transfer verified **individual** applicant data between authorized parties via reusable KYC protocols, which allow previously verified customers to avoid repeating the full verification process when onboarding with new partner services.

Make use of the [Prefill Customer Details](../api-reference/prefill-customer-details)
endpoint to share KYC'd applicant information that leverage these cryptographically secured tokens, transferring compliance profiles with documents and verification status while meeting regulatory requirements.

:::info Scope
Token share applies to **individual** KYC only. Company-level KYB profiles cannot be imported via `SumSubToken`. For business customers, use [Business Customer Prefill](../recipes/onboarding/business-customer-prefill.md). On business prefill, Sumsub tokens on **associates** (UBOs, representatives) import that person as an individual applicant only.
:::

When compliance profiles are added to Sumsub, Noah's KYC platform, the system identifies missing information needed for regulatory compliance. Instead of re-requesting all documentation, missing information is requested through [Dynamic Forms](./dynamic-ui.md) or [Hosted Onboarding](../recipes/onboarding/hosted-onboarding.md) sessions, reducing redundant processes while meeting due diligence requirements.
