Did You Know That Certain Countries Require a Passport for Domestic Travel?

In some countries, traveling from one region to another can necessitate a passport, even for domestic trips. For instance, in places like the United States, while citizens generally don't require a passport to travel between states, there are exceptions in territories like Puerto Rico, where travelers might need to show identification that is equivalent to a passport. Additionally, countries with strict internal border controls, such as India, require citizens to present identification when moving between states. This regulation can often surprise travelers who assume that a passport is only necessary for international travel. Understanding these unique requirements can enhance your travel planning and ensure a smoother journey within a country's borders.
