The Henley Passport Index is a list of the most powerful passports, ranking them every year based on a number of criteria like the need for visas when traveling, visa-free entries, or the use of e-visa. Several of the countries listed tied on the number of countries their passport allows entry to, and you’ll see this reflected by multiple entries sharing the same ranking.
