The world has 195 to 249 countries. If you were asked by someone about – How many countries are there in the world now? Do not just give the number right what is in your mind. You have to consider that there are sovereign states according to the UN, there are states with at least partial recognition, there are also De Facto sovereign states, there are Olympic nations, there are FIFA countries eligible for the World cup and there are country codes in the ISO standard list. So you should become familiar to the six possible answers to the question and they are all considered correct.
