The large-scale aggression by Russia against Ukraine drastically changed how and which administrative services are delivered to its citizens. Physical facilities and communications infrastructure have been damaged or occupied in many areas of the country. This created the need to adapt or propose new ways of providing administrative services and the creation of entirely new services. The system of service delivery has had to be relaunched, adapted and even transformed. During the first days of the war there were almost no services. After three months the system had adapted to wartime conditions. The Ukrainian system of administrative service delivery has proved itself resilient in terms of safety and security, and in terms of responses to the new needs of the population. The simplification, deregulation and digitalisation efforts of the government will continue after the war.
