Online product (or service) review platforms are increasingly incorporating receipt-based consumer verification as a means of filtering out fake reviews. In this method, consumers are required to upload a photocopy of their receipt before they can write a review. This study aims to examine how this additional step before writing a review impacts the length and ratings of the online review. We analyze a large-scale database of reviews obtained from a prominent Korean portal that initially featured a platform-verified review system only but later introduced a receipt-based consumer-verified review system. The unique contextual setting, where a single platform offers both platform-verified and consumer-verified review systems, enables us to compare review elements between the two different systems without being concerned about potential effects arising from differences in platform characteristics. We found that receipt-based consumer verification leads to shorter and more negative reviews compared to platform verification. We also found that the introduction of a consumer-verified review system reduced the average review duration in the platform-verified review system. We discuss the theoretical and managerial implications of the study.
