Internet of Things (IoT) technology is accelerating societal and lifestyle changes, yet its application in E-government public services remains inadequate. E-government public services have a direct impact on public life and development, and they reflect the government’s governance capabilities. Technological improvement is critical to the development of E-government public services. In this paper, the technical characteristics and advantages of IoT technology applied to E-government public services are systematically outlined and analyzed. The technical challenges faced by the current development of E-government public services are examined, and how IoT technology can be leveraged to improve these services is explored. By integrating emerging technology applications, creating a data-driven environment and a distributed multicenter, opening up government–civilian interaction channels, and developing intelligent scene-based services, IoT is utilized to significantly enhance public service experiences and effectively improve public services. The utilization of IoT technology in E-government public services presents enormous potential, as it facilitates the advancement of such services and supports the transformation of governmental organizations and social governance models. This report offers guidance for policy makers, implementers, and IoT technology engineers on comprehending the implications of IoT technology in E-government public services.
