KBC Bank Bulgaria and UBB united under the name United Bulgarian Bank (UBB)

On 10th of April 2023, UBB and KBC Bank Bulgaria officially united after the re-organization of KBC Bank Bulgaria EAD, through its merger into United Bulgarian Bank AD, was entered in the Commercial Register. The legal merger is the next step in the integration of the two banks after the Belgian KBC Group acquired the business of Raiffeisen Bank International in Bulgaria in the summer of 2022.

The process of the technical integration of UBB and present KBC Bank Bulgaria is underway. Until its finalization, our branch network, corporate website and the digital channels of the up-to-now KBC Bank Bulgaria will have a special symbol next to UBB logo. At this stage, clients do not need to take any actions and will continue to be serviced as until now. We will inform you about any future changes.
