Risk & Compliance

Merchants in the unclassified insurance sector face substantial risk and compliance challenges due to the potential for high chargeback rates and various types of fraud. PSPs and acquirers maintain stringent governance, necessitating proactive measures from merchants to effectively manage regulatory expectations and mitigate risks.

Chargebacks & fraud

High rates of friendly fraud as customers may falsely claim non-receipt or dissatisfaction with services.

  • Common patterns include policy misrepresentation and fraudulent claims, especially around travel or health insurance.
  • Mitigation strategies encompass tools such as device fingerprinting, transaction monitoring for unusual patterns, and clear communication of terms and conditions to clients.

AML/KYC expectations

Robust identity verification is crucial, including thorough verification of identity documents and checks against sanctions lists.

  • Regular source-of-funds verification, especially for high-value policies or unusual payment methods.
  • Triggers for manual reviews include large or frequent policy purchases, atypical payment paths, or the use of mixed payment methods.

Operational red flags

Lack of transparency regarding policy ownership or the identity of beneficial owners can lead to heightened scrutiny.

  • Inconsistent or unclear documentation processes when onboarding clients.
  • Insufficient customer support channels and grievance redressal mechanisms can raise concerns about operational integrity.
  • Failure to communicate clear refund or cancellation policies to clients can lead to disputes and chargebacks.

Operator licenses

Insurance Regulatory and Development Authority of India (IRDAI) — regulates insurance providers in India, ensuring they meet necessary operational guidelines.

  • Financial Conduct Authority (FCA) — oversees financial services firms in the UK, including certain types of insurance businesses.
  • State insurance departments in the US — each state has its own regulations and licensing procedures for insurance providers.
  • National Association of Insurance Commissioners (NAIC) — provides a framework for state regulations but is not a licensing body itself, yet compliance with its standards is essential.
  • Some jurisdictions may require specialized licenses depending on the type of insurance offered (e.g., life, health, property).

Geo-restrictions

Many global regions have stringent regulations; insurance services may be limited to licensed practices within those jurisdictions.

  • Cross-border insurance sales are often heavily regulated, with some countries imposing outright bans.
  • Certain PSPs may decline to process transactions from unlicensed or grey markets.

Certifications & audits

Compliance with PCI DSS for any handling of cardholder data in insurance transactions.

Official Definitions & Network Comparisons

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

Network Definition Key notes
Visa Insurance services not classified elsewhere May require specific documentation; subject to regional regulations
Mastercard Unclassified insurance services Typically requires proof of insurance licenses; varies by country
American Exp. Insurance products not specifically categorized Stricter scrutiny on business type; may impose higher fees

Explanation:

While all networks address unclassified insurance services, differences in their definitions signal varying requirements for merchant onboarding. Terms like "unclassified" versus "not categorized" can lead to unique processing rules. Common reasons for application rejections include inadequate licensing, failure to meet regional compliance, and lack of clarity in business activities.

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.

MCC How it is used Why confused When acceptable What is risky
6311 Life Insurance “We sell various insurance products” Selling life insurance products Misclassifying as non-insurance-related services
6351 Health Insurance “We provide health insurance options” Providing legitimate health insurance Mislabeling to avoid scrutiny or lower fees
7349 Services of a general nature “We offer general business-related services” Generic service providers (not insurance) Claiming insurance services while offering unrelated ones
6010 Financial institutions “We are a financial service provider” Banks and recognized financial institutions Misclassifying insurance as a financial service risk

Rule of thumb for merchants:

Ensure your business activities align closely with the specified MCC for your services. Misclassifying under an alternative code to evade higher fees or scrutiny can lead to compliance issues and potential account penalties. Always choose the MCC that accurately reflects your core operations.

Best Practices for Merchants

Merchants categorized under MCC 6399 (Insurance - Unclassified) need to adopt best practices that promote transparency and build trust with customers while effectively managing their payment operations.

Classification & transparency

always use the correct MCC; accurate classification helps maintain compliance and avoid account issues

  • clearly display insurance offerings, terms, conditions, and responsible business practices on your website

Fraud & chargeback reduction

  • maintain logs for transaction history and customer interactions to build a strong case during dispute representments

Payment acceptance optimization

offer a variety of payment methods, including cards, digital wallets, and bank transfers, to cater to diverse customer preferences

  • establish regular compliance audits to review internal policies and ensure adherence to industry standards
  • designate a responsible individual or team to manage disputes, ensuring clear communication and adherence to service level agreements (SLAs) for response times

Payouts & liquidity
