Croatian Post has segmented its internal organization so that it focuses on individual products and services and simultaneously integrates the company's business segments into a complete corporation. Recently, Croatian introduced a new internal organization in which it divided its main business segments into Divisions and Regions so that the core business could be performed even more functionally and rationally while following the constantly changing needs of today's users to fulfil our mission - to be at the service of citizens.
 
The company is divided into four divisions: Post, Express, Network and Support. The Post, Network and Express Divisions are territorially organized, while the Support Division is centralized due to cost efficiency.

The regions consist of delivery services, post office network management services, transportation departments and area sorting operations, and maintenance and cleaning areas.

In addition to the divisions, Croatian Post also has thirteen management support offices. With this organization, business communication has been improved, and the organizational structure is now based on orientation towards the user, as well as clear powers and responsibilities.
