Payment Insights & Benchmarks

Merchants in this MCC should prepare for unique payment dynamics that may not align with conventional e-commerce practices. Understanding payment performance and managing risks will be crucial for optimizing revenue.

Payment methods

Cards: common but subject to higher scrutiny and varied approval rates based on customer profiles.

• E-wallets: increasingly favored for their ease of use and faster transaction times.
• Automated Clearing House (ACH): suitable for direct bank transfers, though slower in processing.
• Prepaid payment methods: offer anonymity, which can be appealing but may attract fraud.

Authentication & security

Strong customer authentication practices (such as 3DS) are essential for reducing risk but may impact approval rates.

• Implementing fraud detection systems can mitigate unauthorized transactions but require continuous tuning.
• Trends in customer behavior should be closely monitored to identify potential fraud patterns.

Benchmarks (indicative, not guaranteed)

MDR: generally higher compared to standard e-commerce rates.

• Rolling reserves: may be implemented, potentially exceeding 10% based on risk assessments.
• Settlement times: often extended, averaging around 5 to 10 days.
• Chargeback ratios: likely to be higher than traditional merchant categories.
• Approval rates: can fluctuate significantly, often below e-commerce benchmarks.

Key metrics to monitor

Transaction approval rates segmented by payment method.

• Trends in chargebacks categorized by fraud vs. customer dissatisfaction.
• Average transaction values and order frequency for customer insights.
• Payment method performance, focusing on payment failure rates.

Risk & Compliance

Merchants categorized under MCC 3137, typically involved in the sale of prepaid cards, face significant scrutiny from payment service providers (PSPs) and acquirers. This scrutiny stems from the high risk of fraud and chargebacks, necessitating stringent compliance with AML/KYC regulations and proactive management of operational risks.

Chargebacks & fraud

Prepaid card transactions are susceptible to friendly fraud, where customers deny transactions they participated in, and bonus abuse, where users exploit promotional incentives.

• Fraudsters often use stolen credit cards to fund prepaid cards, leading to disputes once the unauthorized charges are identified.
• Common mitigation tools include velocity checks to monitor rapid successive transactions and device fingerprinting to identify and block suspicious devices.

AML/KYC expectations

Merchants must implement strong identity verification processes, including thorough checks against sanction lists and politically exposed persons (PEPs).

• Source-of-funds verification is essential, especially for large transactions or unusual purchasing patterns.
• Manual review triggers involve multiple purchases by the same individual in a short time span or transactions that originate from high-risk jurisdictions.

Operational red flags

Lack of transparency regarding ownership or operational structure can alarm PSPs, particularly in white-label scenarios.

• Unclear traffic sources or partnerships with affiliates that lack verification can increase the risk profile.
• Absence of responsible gaming mechanisms, such as self-exclusion options and defined withdrawal limits, raises compliance concerns.
• Vague or nonexistent policies for refunds and returns may indicate higher risk exposure and could trigger further scrutiny.

Official Definitions & Network Comparisons

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

Explanation:

While networks provide similar definitions around short-term lodging, variations in terms such as "single use" and "transient guests" can affect how merchants are classified. Different networks may require distinct compliance checks based on local regulations. Common reasons for denial include non-compliance with local lodging laws, excess chargebacks, and mischaracterization of service types.

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.

Rule of thumb for merchants:

If your business primarily deals with specific agricultural products or raw materials, ensure you use the correct MCC 3137. Misclassifying your business under alternative codes can lead to compliance issues and potential account reviews or closures.

Best Practices for Merchants

Merchants under this MCC face higher scrutiny and must actively manage payments, risk, and operations. The practices below help build sustainable acceptance and reduce exposure to disputes and PSP restrictions.

Classification & transparency

always use the correct MCC; attempts to bypass classification often lead to account closure

Fraud & chargeback reduction

implement 3DS or step-up authentication for high-risk signals (amount, geo, device, velocity)

• use clear billing descriptors, instant confirmations (SMS/email), and responsive customer support
• log transaction and gaming events to build evidence for dispute representments

Payment acceptance optimization

support multiple methods (cards, wallets, vouchers, local A2A) to reduce dependency

• route traffic by geography, bank, or method and test PSP performance regularly
• use separate MIDs for product types or regions to manage scheme requirements

Operational discipline

track KPIs such as auth rate, decline codes, chargeback ratio, ARPD, and LTV

• schedule compliance audits, update internal policies, and run test purchases
• assign a dedicated owner for disputes with SLA-bound responses

Payouts & liquidity

maintain liquidity buffers to cover rolling reserves and extended settlements
