Payment Insights & Benchmarks

Merchants in the car rental industry should be prepared for a more complex payment environment compared to standard e-commerce. Factors such as customer behaviors, transaction amounts, and risk management strategies significantly influence payment performance.

Payment methods

Cards: primarily credit cards are accepted; however, some cards may be declined due to high fraud risk.

• E-wallets: gaining traction for quick transactions but not universally adopted by all rental platforms.
• A2A payments: increasingly popular for their convenience and quick settlement but may have higher fees.
• Corporate accounts: often used for business rentals, though these may involve specific credit checks.

Authentication & security

Strong customer authentication practices (e.g., 3DS) are commonly implemented but may impact conversion rates.

• Fraud detection mechanisms are critical due to high-value transactions in this sector.
• Reputational fraud may occur; hence, vigilance on customer behavior patterns is essential.

Benchmarks (indicative, not guaranteed)

MDR: typically elevated compared to standard e-commerce sectors.

• Rolling reserves: might be necessary to mitigate high chargeback risks.
• Settlement times: generally longer than usual—up to 7-10 days is not uncommon.
• Chargeback ratios: often higher than other retail sectors, due to disputes with customer expectations.
• Approval rates: usually lower for card transactions, with better rates found via alternative payment options.

Key metrics to monitor

Transaction decline rates broken down by payment method and reason.

• Chargeback rates, particularly focusing on the type of disputes (service-related vs. fraud).
• Average transaction values and frequency of customer bookings to understand cash flow dynamics.
• Customer feedback and service ratings to identify areas of potential refund disputes.

Risk & Compliance

Merchants operating under the MCC 3393 face significant financial and reputational risks associated with customer disputes and fraudulent activities. PSPs and acquirers impose stringent controls, requiring merchants to effectively manage chargebacks, fraud, and compliance with AML/KYC standards.

Chargebacks & fraud

Common types of fraud include friendly fraud ("I didn't authorize this transaction"), vehicle theft, and reservation manipulation.

• Duplicate bookings or cancellations to exploit promotional offers are frequent abuse patterns.
• Effective mitigation tools include device fingerprinting, velocity checks, and thorough receipt verification processes.

AML/KYC expectations

Robust identity verification processes (IDV) are required, including checks against sanctions lists and PEPs.

• Monitoring of source-of-funds for larger transactions or any suspicious behavior is essential.
• Manual review triggers include inconsistencies in booking details, use of multiple payment methods, or significant last-minute rental changes.

Operational red flags

Lack of transparency concerning ownership and management of rental agencies raises significant concerns.

• Unclear policy on refunds or cancellations could draw scrutiny from PSPs.
• Traffic from unverified or multiple affiliates may signal potential fraud.
• Inadequate documentation or inconsistent record-keeping related to customer interactions can raise alarms.

Operator licenses

Vehicle Rental Business Licenses — these are often required at the local or state level, verifying that the business meets safety and operational standards.

• Local transportation authority permits — may be necessary for operating within specific cities or regions, with requirements varying significantly.
• Environmental permits — some areas require compliance with environmental regulations related to vehicle emissions for rental fleets.

  Geo-restrictions

Transactions may be restricted in countries with stringent vehicle rental regulations or bans on foreign companies.

• Local regulations often dictate fleet composition, insurance requirements, and pricing structures.
• PSPs may refuse to onboard businesses operating in regions deemed high-risk for vehicle theft or fraud.

Certifications & audits

• Regular audits for operational standards, which can include vehicle condition checks and maintenance records.

Official Definitions & Network Comparisons

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

Explanation:

While all networks recognize car rental services, differences in terminology and definition nuances can impact the onboarding process. Some networks may demand specific documentation regarding licensing and insurance, or have additional evaluation criteria based on the merchant’s geographic location or business model. Common reasons for denial may include incomplete applications, insufficient documentation, or geographical limitations in service areas.

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:

Ensure your classification is precise—if your business is primarily focused on national car rentals, use MCC 3393. Mixing it up with other vehicle-related codes can open you up to compliance risks and lead to financial repercussions.

Best Practices for Merchants

Merchants under the National Car Rental MCC must adopt effective operational strategies to navigate the unique challenges of the car rental industry. These best practices help in managing risk, optimizing payment acceptance, and fostering strong relationships with payment service providers (PSPs).

Classification & transparency

Fraud & chargeback reduction

implement 3DS or step-up authentication for transactions deemed high-risk (e.g., large amounts, unfamiliar devices)

• use clear and descriptive billing statements to inform customers about charges
• log rental agreements and customer interactions to support dispute resolutions

Payment acceptance optimization

offer multiple payment options (credit cards, debit cards, mobile wallets) to cater to diverse customer preferences

• analyze transaction data to optimize routing by geographic location, ensuring higher approval rates
• consider using separate Merchant Identification Numbers (MIDs) for different rental locations or vehicle types

Operational discipline

regularly track KPIs such as rental transaction success rate, chargeback ratio, and customer satisfaction scores
