The Croatian National Bank has opened a free of charge facility to exchange Bulgarian lev (BGN) into euro in the context of Bulgaria joining the Eurosystem on 1 January 2026. The service runs from 2 January to 2 March 2026 and applies the fixed conversion rate. Exchange is available at BGN 1.95583 per EUR 1, with a maximum of BGN 2,000 per person and transaction per day, and is carried out at the CNB’s cash desk in Zagreb during 08:30 to 15:30, Monday to Friday. Coins and banknotes that no longer have legal tender status are not eligible, and the CNB may require proof of origin for banknote exchange transactions.
