The National Pension Service (NPS) developed a system that connects social insurance computer network and established the Social Insurance Information Center at the NPS in February 2003 to allow citizens to register once by visiting any office of the four social security organizations or via online to resolve inconveniences of having to make requests or submissions at each of the organizations of the four social insurances (National Pension, National Health Insurance, Employment Insurance, and Workers’ Compensation Insurance). Integrating the channels for the four social insurance schemes enabled citizens to easily apply for, make changes to and request for withdrawal of the four social insurance schemes. Connecting national information resources also allowed for simplifying and streamlining various application forms and documents, leading to an improvement of efficiency in processes. In addition, it is recognized as a ground-breaking service in light of its user-friendly environment in checking their insurance history and status online.
