I am a unverified paypal user cause I live in Israel and I buy domains on namecheap..
I din't see any reason y not.. and I added a valid cc to my account.. that is how I recieved payments..
i can pay and buy domains at domainsite.. but i wanted to use godaddy to reg my domains if somehow i could manage to pay them via and unverified paypal
GoDaddy doesnt allow you to pay with a paypal account that does not have a CC on file. The reason being is that in the event that there is a chargeback or paypal is unable to secure funds from a bank account, there is no backup funding source to go after. Its simply done to eliminate risk of not getting paid. Pain in the booty, but considering the markup on domains is so small, it doesnt suprise me that they are so strict about it.
Unverified paypal can receive and can send money. Theres no need to add credit card on it, unless if you need money on it. If you have money on unverified paypal, then use it. Feel free to do that. I don't know about godaddy, but Namecheap accepts unverified paypal. Regfly also.
