Poštna banka Slovenije was established by the former Slovene PTT organisations. The bank commenced operations on 1 July 1992, immediately after Poštna hranilnica Beograd had ceased its operations.
It is typical of Poštna banka Slovenije that it operates via the largest and the most extensive network of Pošta Slovenije outlets. All postal outlets in Slovenia, i.e. their counters providing cash transaction services, are also the Poštna banka Slovenije’s counters. The postal outlets have more favourable (longer) opening hours, including on Saturdays.
In cooperation with Pošta Slovenije, the bank has also set up its own independent units. In Ljubljana and Maribor, the bank has two commercial centres offering mainly retail services. In Murska Sobota, Celje, Kranj and Koper, it has its representative offices primarily offering services to corporate customers.
