Korea post delivers more than 4.7 billions of mails and parcels per year. Although postal service is invoked by mail acceptance from customers, mail acceptance service is not as mature as sorting or delivery service in terms of automation and informatization. In this paper, we reviewed current status and issues of the mail acceptance service, analyzed relavent technologies and foreign case-studies, and suggest an information strategy plan for better service. According to the strategies, we propose several action plans for applying adequate information technologies. In addition, we address important results of patents analysis for major technologies. The results of this study could contribute to determining the information strategy and the R&D plan for future postal service.
