Starting in October, Americans and other non-EU citizens will have to be fingerprinted to enter Croatia. Starting on Oct. 12, 2025, Croatia will be the first European Union country to implement the Entry/Exit System, or EES, in the European Union, according to TravelOffPath. According to the European Union’s official Entry/Exit System (EES) website, the system will be enacted in all EU countries by April 10, 2026. Why does the EES border system require your fingerprints? The EES border system is designed to replace a traditional passport stamp.
