What can a passport actually open?
Rank and compare the world's passports by the number of destinations accessible without an advance traditional visa.
This measures travel mobility, not the full value of citizenship. Residence rights, work rights, consular protection, tax exposure and family transmission are separate questions.Put two mobility profiles side by side.
A score difference tells you how many more destinations are accessible without an advance traditional visa in the underlying dataset. It does not tell you which destinations differ, or which passport has stronger residence or work rights.
Passport power is more than one number.
Use the mobility score as a first comparison, then read the actual entry mechanism and the broader citizenship rights behind the passport.
Travel information changes quickly. This index is informational and uses an open mobility dataset. It is not a boarding decision, immigration clearance, visa determination or guarantee of admission. Airlines commonly use systems such as IATA Timatic for operational document checks; travelers should verify their specific nationality, document, route and purpose with official authorities before departure.
