The data for the Holy See is based on the 2023 Passport Index, as the relevant indicators were either unavailable or not updated for 2024. Ranking 198th in the Global Passport Index, the Holy See’s passport grants visa-free access to 91 countries, including within the Schengen Zone. In contrast to higher-ranking passports, it allows visa-on-arrival access to 33 countries and electronic visas for 23. On the Enhanced Mobility Index, which assesses the desirability and strategic importance of accessible destinations, the Holy See ranks 62nd. Due to a lack of data on Quality of Living and Investment Index indicators, its ranking largely reflects its travel privileges and diplomatic influence, as captured in the Enhanced Mobility Index.
