There is nothing "country" specific as far as Jamaica (in my experience), I have been using PayPal to get money to my best friend at the house in Accompong Town for nearly 10 years now. Of course, what I do is give him a card and he uses the ATM to get the money but I wouldn't think that would make any difference. I will be interested to see if others have tried to send it to someone in Jamaica's account and they did have a problem though.
