The Nigerian passport has been ranked 191st out of 199 countries, making it the 10th worst travel document in the world, according to VisaGuide’s World Passport Index.

The report shows that as of April, the Nigerian passport was placed just above countries like North Korea (192), Iraq (193), Libya (194), Sudan (195), Pakistan (196), Afghanistan (197), Syria (198), and Somalia (199).

The index is a passport ranking system that uses the Destination Significance Score (DSS) to assess and rank the passports of countries and territories.

The ranking is determined based on several factors, including entry policies, GDP, Power Index, Tourism Index, and Human Development Index (HDI), among others. These factors are used to calculate a unique value for each passport.

In the latest index, the Singaporean passport was ranked the strongest in the world, followed by the Italian passport. Spanish, French, and German passports ranked third, fourth, and fifth, respectively.

According to the report, “A unique DSS value is assigned to each destination based on the entry policy it enforces on the passport, GDP, Power Index, Tourism Index, and HDI, among other factors. The DSS is multiplied by the value of the visa requirement of the destination country toward the selected passport holders.”

Other factors that influence the rankings include visa-free travel, electronic travel authorisation, visa on arrival, electronic visa (e-visa), embassy or other government-approved visas, passport-free travel, and banned entry.

The report notes that since destination countries are each assigned a unique DSS, “Being able to travel visa-free to a destination with a higher DSS gives the selected passport a higher value than having visa-free access to a country with a lower DSS.” This ultimately leads to a more accurate ranking for each passport.
