Digitization of business is a ubiquitous process in all sectors of an economy. This is exactly how it takes place in terms of public services. The public sector as a provider of public services is often an under-researched area at the same time and public services have not received a sufficient amount of attention. Digitization of public services is a rather unexplored topic on the domestic market, although the digitization process is gradually taking place. Faced with technological progress, the public sector is undergoing a process of transition to the digital world. Using the example of the e-Citizens portal as the bearer of the digitization of public services, the digitization process itself can be shown, as well as the types of services available on it. Through the process itself, the current state of digitization in Croatia is shown, as well as the way the portal itself functions, as well as the services it combines. The integration of public institutions represents a very important role in the digitalization process that enables the functioning of the portal. The paper presents conclusions about digitization and its process, as well as the effects that result from it. On the basis of research among citizens, their knowledge about the processes and concepts covered in the paper was processed. The public's attitudes towards the progress of digitization and awareness of its current state were investigated. The basket of available services is presented and the results of the frequency of use and representation of each individual service are presented, on the basis of which conclusions can be drawn about the need for improvement and unnecessary services and functions of the portal.
