Payment Insights & Benchmarks

Merchants in this MCC should anticipate unique challenges around payment processing tied to the specialized nature of their offerings. Acceptance depends significantly on the chosen payment methods and the level of fraud controls in place.

Payment methods

Cards: can be subject to strict scrutiny, leading to potentially lower approval rates, particularly for certain transaction types.

• E-wallets: a popular option for customers seeking convenience and security, but may have varying acceptance levels based on the business model.
• A2A payments: useful for direct transactions, though they often entail additional integration complexities.
• Prepaid cards: offer a layer of privacy, reducing chargeback risks but may have limited usability.

Authentication & security

Enhanced authentication measures, such as 3DS and strong customer authentication (SCA), are frequently required to reduce fraud.

• These tools help minimize unauthorized transactions but may not fully eliminate friendly fraud challenges.
• Continuous fraud monitoring should consider behavioral patterns and transaction context.

Benchmarks (indicative, not guaranteed)

MDR: generally higher than the average for standard e-commerce.

• Rolling reserves: may be noticeably significant, reflecting higher risk profiles.
• Settlement times: often longer, sometimes exceeding 7 days.
• Chargeback ratios: typically elevated compared to traditional retail sectors.
• Card approval rates: may be lower, while alternative methods might exhibit better acceptance.

Key metrics to monitor

Authorization rates segmented by payment method and transaction type.

• Notable decline reasons organized by payment schemes.
• Chargeback rates analyzed by type and cause, distinguishing between fraud and service issues.
• Transaction volume trends to stay ahead of any emerging fraud patterns.

Risk & Compliance

Merchants under this MCC face significant scrutiny due to the potential for financial fraud and compliance issues. PSPs and acquirers typically enforce stringent checks, requiring merchants to proactively manage risks associated with chargebacks, fraud, and AML/KYC adherence.

Chargebacks & fraud

Common types of fraud include friendly fraud (e.g., customers claiming they didn’t authorize a transaction) and the use of stolen payment methods.

• Bonus abuse can lead to chargeback patterns and suspicious activity affecting profitability.
• Mitigation tools such as device fingerprinting, transaction monitoring, and behavioral analytics help identify and prevent fraudulent activity.

AML/KYC expectations

Robust customer identity verification processes are essential, including identity document validation and sanctions/PEP list checks.

• Merchants should perform source-of-funds verification, especially for larger transactions or when patterns deviate from the norm.
• Triggers for manual review may include frequent high-value transactions, unusual funding sources, or transactions from identified high-risk jurisdictions.

Operational red flags

Lack of transparency regarding beneficial ownership can be a significant warning sign for PSPs, putting merchants at risk.

• High volumes of traffic from unverified third-party affiliates or funnels from prohibited locations may attract scrutiny.
• Insufficient responsible gaming policies, such as failing to implement self-exclusion mechanisms, can alarm acquirers and impact business operations.
• Absence of clear customer service channels for dispute resolution or non-communicative refund policies may lead to increased chargeback activity.

License recognition varies significantly based on the merchant’s jurisdiction and target markets.

• Local state health department licenses — may be required for the sale of health-related products and services at the state level.
• Some markets require specific licenses for different types of health services, such as telehealth or pharmacies.

Geo-restrictions

Certain countries may have outright bans on specific health products or services, leading to transactional blocks by PSPs.

• In the US, regulations can vary by state, especially concerning telehealth and medical devices, requiring state-level approvals.
• Many PSPs restrict transactions from jurisdictions where health product regulations are not clear or compliant with international standards.

Certifications & audits

ISO 13485 for quality management systems in medical device manufacturing and services.

Official Definitions & Network Comparisons

This section shows how major card networks define this MCC and highlights practical differences that affect merchant onboarding.

Explanation:

The terminology differences among networks such as "analytical" versus "diagnostic" can impact the categorization of services. Many networks require proof of certification or accreditation, demonstrating that the merchant meets industry standards. Common issues during onboarding may arise from a lack of proper documentation, inconsistent regional regulations, or concerns related to the clarity of service offerings.

Alternative MCC Codes

Merchants often confuse this MCC with other categories. The table below shows which codes are related, why they are confused, and what risks misclassification brings.

Best Practices for Merchants

Merchants under the MCC code 3824 must prioritize effective payment management and risk mitigation strategies to thrive in a competitive environment. By following best practices, businesses can enhance their acceptance rates, protect against fraud, and cultivate strong relationships with payment service providers.

Classification & transparency

always use the correct MCC; classification discrepancies can lead to account penalties or closure

• provide clear disclosures of services, policies, and geographic limitations on your website
• ensure transparent communication of transaction descriptors to help customers recognize charges

Fraud & chargeback reduction

implement 3DS or step-up authentication for transactions flagged as high-risk based on various signals

• utilize descriptive billing that’s easy for customers to identify and verify, coupled with responsive support options
• maintain detailed logs of transactions and customer interactions to assist in dispute resolutions and representments

Payment acceptance optimization

enable multiple payment methods (credit cards, e-wallets, direct bank transfers) to increase customer choice and reduce risk

• optimize payment routing based on customer location, payment method, or performance of payment processors
• consider using separate merchant IDs (MIDs) for different product lines or service types to streamline operations

Operational discipline

establish and monitor key performance indicators (KPIs) such as transaction success rate, chargeback rates, and average transaction values

• conduct regular compliance audits and assessments to ensure adherence to internal policies and industry standards
• designate a specific person or team to manage disputes, ensuring timely responses that adhere to service level agreements (SLAs)

Payouts & liquidity

prepare for rolling reserves and extended settlement periods by maintaining adequate liquidity buffers
