*** title: KYC Reliance using Sumsub slug: features/kyc-reliance-sumsub subtitle: Reuse existing Sumsub KYC data to eliminate redundant user verification --------------------------------------------------------------------------------- **KYC Reliance using Sumsub** allows partners to reuse their existing Sumsub KYC data with Transak, eliminating the need for users to complete verification again. ## Problem Statement Traditional integration flows require users to complete KYC verification separately for each platform, creating unnecessary friction and delays in the user journey. Here are some of the **key challenges** with duplicate KYC processes:
Redundant verification
Users must repeat KYC verification even though they're already verified on partner platform.
Slower onboarding
Additional KYC steps significantly delay user onboarding and increase time to first transaction.
Poor user experience
Users are frustrated by having to upload documents and complete verification multiple times.
Lower conversion rates
Duplicate KYC requirements create drop-off points that reduce user conversion and activation.
## Our Solution KYC Reliance allows partners to share their existing KYC data with Transak using Sumsub, eliminating duplicate verification and creating a seamless one-click onboarding experience. Here are some of the **key benefits** of the KYC Reliance solution:
