Risk & Compliance

Merchants under this MCC are subject to heightened risk assessments and regulatory scrutiny due to the nature of financial transactions involved. PSPs and acquirers require robust measures to manage fraud, chargebacks, and compliance with AML/KYC regulations.

Chargebacks & fraud

Common issues include friendly fraud, where customers dispute legitimate charges, and fraud involving the use of stolen cards and account takeover.

• Chargeback patterns may arise from dissatisfaction with service delivery or product quality, as well as attempts to reclaim bonuses or free bets.
• Effective mitigation tools include velocity checks, fraud detection systems, and customer authentication methods like two-factor authentication (2FA).

AML/KYC expectations

Merchants must implement strong identity verification processes, including comprehensive checks of government-issued IDs and document verification.

• Sanctions and politically exposed person (PEP) checks are essential before onboarding customers to mitigate risks associated with illicit funding.
• Triggers for manual review include unusual transaction patterns, high-risk jurisdictions, and discrepancies in customer information.

Operational red flags

Lack of transparency about the merchant's ownership, especially in white-label arrangements, can raise concerns for PSPs.

• Traffic sourced from suspicious or unverified affiliate networks may indicate potential fraud risks or compliance issues.
• Insufficient customer protection policies such as clear terms for refunds or disputes may signal operational weaknesses.
• No responsible gambling measures in place, such as options for self-exclusion or monitoring of player behavior, can be alarming to acquiring partners.
