Which country Cannot use Coinbase?

I'm quite interested in the world of cryptocurrencies and have been exploring different platforms to buy and sell digital assets. Recently, I heard about Coinbase, which is a popular crypto exchange platform. However, I'm curious to know if there are any countries where Coinbase is not accessible or cannot be used? I understand that due to various regulatory and compliance issues, some platforms might not be available in certain regions. So, I'm just wondering if there's a list or a specific country where Coinbase is not operational. If you could provide me with some insight or point me to a resource where I can find this information, it would be much appreciated. Thank you for your time and assistance!
