South America has 12 sovereign countries, so a country-based capital list has 12 entries. One entry needs extra care. Bolivia uses Sucre as its constitutional capital, while La Paz serves as the seat of government. That is why some lists show 12 capitals, while others mention 13 city names.
There is another point that often causes confusion. French Guiana is in South America, and its administrative center is Cayenne, yet French Guiana is an overseas department of France, not a sovereign South American country. For a list of South American national capitals, it does not belong with the 12 sovereign states.

Why the Count Can Look Different
Bolivia Uses Two Capital Names
Why does Bolivia appear with two capitals in so many lists? Because two different ideas are in play. Sucre is the constitutional capital. La Paz is where the executive and legislative branches work day to day. A short list that only shows La Paz is easy to read, but it is not legally exact. A precise list should name both cities and explain the split.
French Guiana Is Not Part of the 12-Country Capital List
Some regional pages add Cayenne because French Guiana is on the continent. That makes sense in a broad geographic list of places in South America. It does not fit a list of national capitals for sovereign South American states. The 12-country list ends with Venezuela, not French Guiana.
