FAQ

The index includes only passports of countries that are full member states of the United Nations. I closely monitor changes in UN membership and international recognition; as soon as a country attains full member status, it will be added to calculations.

Each score is the direct result of the formula detailed in Methodology section under the “PQI (Passport Quality Index)” block. I guarantee that the process is entirely transparent and free from any intentional bias or manual adjustments. However, if you believe there is a data error or a discrepancy in the calculation, I am open to reviewing it. Please feel free to reach out at [email protected].

Please send cases to [email protected]. I will try to correct them not only at the level of my project but also make edits to Wikipedia to make accurate data available to Wiki users as well.

Your passport is likely indeed strong, but VFE evaluation works differently. You can learn more in the Methodology section and in the tooltips on the site. Essentially, the rating aims to identify unexpectedly good passports that may not have the highest number of visa-free destinations. It is logical that among them will be far from the most popular passports.

For example, Spain's VFE is lower because they have access to both the most touristic destinations and not-so-popular ones — the median quality of visa-free access is lower, but this does not make the passport bad; it is excellent for travel.

No, the tool evaluates only the mathematical benefit of the combination, not the legal legality of holding two passports.

This is a large field for experimenting with combinations, but one must understand that some passport combinations are practically impossible to have, and many states in practice require renouncing the first citizenship.

This is the main value of the Synergy Tool. Strong passports often have identical lists of visa-free countries. The tool shows that having two "top" passports is often pointless, but if access to the whole world is important to you, then perhaps a not-so-obvious option will be useful for you.
