Powerful Passports.
The International Air Transport Authority (IATA), which forms the basis of the Passport Index. In order to maintain the accuracy of the data provided by IATA in the face of constant updates to visa policy, and in order to create detailed visa lists for all 199 passports in our database , our research team uses publicly available and reliable online sources to cross-check each passport against all 227 possible travel destinations. This research process is ongoing throughout the year. It is coupled with a rigorous monitoring system to pick up relevant visa-policy shifts. This index is basically an analysis of the worlds powerful passports.

Conditions and criteria for Powerful Passports
For each travel destination, if no visa is required for passport holders from a country or territory, then a score with value = 1 is created for that passport. A score with value = 1 is also applied if passport holders can obtain a visa on arrival, a visitor’s permit, or an electronic travel authority (ETA) when entering the destination. These visa-types require no pre-departure government approval, because of the specific visa-waiver programs in place. These passports are amongst the world’s powerful passports as their holders have more travel freedom.
Where a visa is required, or where a passport holder has to obtain a government-approved electronic visa (e-Visa) before departure, a score with value = 0 is assigned. A score with value = 0 is also assigned if passport holders need pre-departure government approval for a visa on arrival, a scenario we do not consider ‘visa-free’.
The total score for each passport is equal to the number of destinations for which no visa is required (value = 1), under the conditions defined above.
