KYB Guide — Corporates
This guide defines the data requirements and validation rules for onboarding corporate customers. Corporate profiles must use KYC Reliance — KYC Sharing via SumSub is not supported for companies.
This guide reflects Monerium's current requirements and is intended to help you design and validate your onboarding flow. It does not replace a formal compliance review. Before going live, you are required to align your onboarding process, risk classification, and data collection with Monerium's compliance team as part of your integration agreement. Requirements may change, and your implementation must remain in sync.
Pre-checks
Perform these checks before submitting any data to Monerium. Companies that fail must be rejected.
- Country of incorporation: Must not be prohibited. See Country of incorporation below.
- Sanctions: Screen the company itself and all directors, representatives, and beneficial owners against applicable sanctions lists (EU, UN, OFAC).
- PEP: Check all directors and beneficial owners for PEP status. PEP status requires source of funds verification.
