United Bulgarian Bank (UBB), part of KBC Group in Bulgaria, is gradually discontinuing the dual visualization of amounts in euro and Bulgarian lev. This follows the expiration on 8 August 2026 of the period for mandatory dual display of fees and transaction amounts in euro and lev, as stipulated by the Law on the Introduction of the Euro in the Republic of Bulgaria.
Starting in September, new versions of UBB Mobile will require iOS 16.0 or later for installation and updates.
