Combating Return Fraud at Scale: How Retailers Can Safeguard Profitability with Data & AI

Return fraud is increasingly becoming a critical issue for retailers, resulting in significant financial losses and operational challenges. In 2024, return fraud led to an estimated $103 billion in losses for the U.S. retail industry, representing more than 15% of all returns.

Understanding Return Fraud

Return fraud manifests in various ways. Common practices include “wardrobing,” where consumers purchase clothing for temporary use and then return it, and “bracketing,” where shoppers intentionally buy multiple sizes or colors, only to return the unwanted items. With the rapid growth of online shopping, these practices have expanded significantly across various product categories—from designer shoes and video games to power tools and seasonal items like holiday decorations.

A notable example reported by PacSun highlights the severity of return fraud: a single customer made 250 fraudulent returns valued at $24,000. Warehouse personnel uncovered used merchandise, counterfeit goods, and even empty boxes, revealing coordinated, organized return fraud schemes often shared through messaging platforms like Telegram.

Leveraging Technology to Combat Fraud

To effectively tackle return fraud, retailers are increasingly turning to advanced technology and data analytics solutions. By analyzing customer behavior, transaction patterns, and inventory data, businesses can swiftly detect suspicious activity, such as unusually high volumes of returns or repeated returns from the same address.

Sophisticated algorithms employing pattern recognition and anomaly detection are critical tools. These algorithms can quickly pinpoint irregular behaviors, such as frequent returns of high-value products or coordinated returns from multiple accounts tied to common IP addresses or payment methods. Additionally, predictive modeling enables retailers to assess the risk level of individual returns based on historical data, setting thresholds to automatically flag or block potentially fraudulent transactions.

Real-time monitoring further empowers retailers, allowing immediate intervention by alerting fraud prevention teams as soon as suspicious activities are detected. Customer behavior analytics complements these measures, differentiating genuine customers from serial fraudsters and allowing retailers to implement targeted policies—such as return limits or additional scrutiny for higher-risk accounts.

The Importance of Digital Systems and Global Analytics

Implementing robust digital systems provides retailers comprehensive visibility into return fraud across products and customers. Enhanced data-driven insights enable businesses to identify problematic patterns and quickly address profit-draining activities. For retailers operating globally, these tools simplify and streamline the returns process, especially for international transactions.

Moreover, leveraging Customer Relationship Management (CRM) and transactional databases allows for proactive fraud investigation, reducing losses by addressing fraudulent activities at an early stage.

Balancing Fraud Prevention and Customer Satisfaction

While stricter return policies are essential in curbing fraudulent activities, they must be balanced carefully to avoid negatively impacting legitimate customers. Companies like Asos have begun deactivating accounts exhibiting patterns of serial returns, whereas retailers such as Zara, J.Crew, and Uniqlo have introduced return fees to discourage misuse.

Effective return fraud prevention strategies must clearly communicate policies, utilize advanced detection technologies, and ensure minimal disruption to genuine customer experiences. Striking this balance is critical for protecting profitability, enhancing operational efficiency, and maintaining trust among honest consumers.

As e-commerce expands, return fraud poses an increasing threat. However, by harnessing advanced analytics, predictive modeling, and real-time monitoring, retailers can significantly mitigate risks, secure their bottom line, and foster stronger relationships with legitimate customers.
