This study investigates the factors influencing consumers' adoption of parcel lockers for last‐mile deliveries. Attitudinal data on parcel locker adoption were collected from individuals in the United States, and structural equation models were estimated to assess consumers' intention to use the lockers as a delivery method. The study is grounded in the Technology Acceptance Model, evaluating perceived ease of use, usefulness, risks, and location preferences. Consumer attitudes indicate that parcel lockers are perceived as easy to use and useful, offering efficient and fast delivery times. Moreover, consumers generally regard these facilities as safe. However, perceived risks include concerns about privacy and the potential loss of packages. The results show that urban residents are less likely to use parcel lockers than suburban residents. Additionally, consumers show a preference for parcel lockers located near their workplaces. The modeling results provide critical implications for service providers, highlighting the features that users value when considering this delivery alternative, thereby aiding in evaluating potential parcel locker implementations.
