Some countries' (such as Cabo Verde and Côte d'Ivoire) official names are often referred to as their outdated names (Cape Verde and the Ivory Coast respectively) on Jetpunk. These countries do not count.
If a country's official name includes a 'the' before the name they are commonly referred to (ex. the Bahamas, the Netherlands, the Philippines...) it still does not count.
A few countries' official names are essentially the words of the name they are commonly referred to but in a different order. These differences do count.
