The backbone of Croatian Post's work is its core activity - the provision of postal services.

Croatian Post is the largest provider of postal services in the Republic of Croatia and the only provider of universal services in the Republic of Croatia according to the Postal Services Act. However, in addition to postal services, an important part of Croatian Post's core business is also numerous payment services that are provided daily in more than 1,000 post offices throughout the country. In accordance with its development strategy, Croatian Post continues to improve its core business by developing infrastructure and improving and automating processes by introducing innovations and digitizing daily work.
 
Package 24
In addition to traditional postal services, Paket24, a fast parcel delivery service that is a partner of the most important global and domestic companies, is also available to users. From the beginning of September 2022, Croatian Post has ensured the fastest delivery to the extreme south of Croatia. This means that shipments from the largest global and domestic e-shops arrive in cities such as Dubrovnik, Cavtat and Ploče just as quickly as, for example, in Zagreb, Split, Osijek or Rijeka. In addition to delivery to the address or to the post office, users of Paket24 can receive and send their parcels via the parcel lockers, the new delivery channel of Croatian Post.
 
Parcel lockers
Parcel lockers are automated devices with compartments of different sizes and are in 300 frequent and easily accessible locations, which can be reached on foot, by bicycle or by public transport. They are available every day of the week, from 0 to 24 hours, and users can collect and send their packages contactless at the time that suits them best, and they can also return goods purchased in e-stores through the parcel locker.
Paket24 – a fast parcel delivery service at Croatian Post, which also delivers parcels ordered in domestic and foreign e-shops to new locations, takes care of the delivery and dispatch of parcels from parcel machines.
