不光是封面顏色和里面的頁數不同，隨著國家之間相互協商，一些護照的通行能力變得較強。每個國家的護照都有一套特有的規定，它們決定了護照持有人能否在海關“一掃而過”，或者輕松實現落地簽。

護照指數每年發布一次，從中可以看出哪些國家的護照通行能力最強。今年的指數已于1月份出爐。不少國家的護照通行能力相當，因此要進入前25名，在該指數中至少要排到并列第六位。

It’s not just the color of the outside or the number of pages inside, as each country negotiates with others, some passports become more powerful. Whether citizens are able to flash their passport and breeze past customs or if it’s easy to get a visa upon arrival, every single country’s passport has its own unique set of regulations.

Passport Index, which ranks the world's passports each year to identify which are the most powerful, released their most recent rankings in January. Several countries tie each other in the global access they provide their passport holders, so to get into the top 25, a country must rank at least as the sixth most powerful.

Here are the 25 most powerful passports in the world.

Australians can use their passport to get into 169 countries without a visa, making it a three-way tie for sixth most powerful in the world.
