The adoption of IoT technology has revolutionized logistics and e-commerce worldwide. IoT smart lockers enable efficient last-mile delivery through secure, automated storing and retrieval. In this article, the viability of smart lockers in Saudi Arabia, in terms of Vision 2030 aspirations, is examined through a qualitative case study, with lessons drawn from international implementations such as Amazon Hub, Hive Box, and InPost Lockers. Economic savings, efficiency in logistics, and ease of use for consumers rank high, but face-to-face preference and compliance with laws and legislation hinder them. There is a critical necessity for localized adaptations for driving adoption, and collaboration with logistics providers and governments is paramount. Integration with Saudi smart city development is a critical opportunity for rollout. Consumer willingness and pilot studies in key urban locations must be considered in future studies. Actionable information for stakeholders for the rollout of IoT-powered smart lockers in Saudi Arabia’s modernization of its logistics infrastructure is presented through this paper.
