Why can't register a domain in GoDaddy

It could be your card is not yet activated... but for what I know is it's activated already once they send the card to you (not unless specified that you need to activate it just like some ATM cards). Try to check with your CC issuing bank/company regaring your card's status.

I believe it's because Electron Visa is a debit card (although some banks will issue it as a credit card and some a debit card). Some businesses will not accept them as they cannot confirm the funds. I would suggest you try obtaining your domain name somewhere else. I develop web pages and recommend Start Logic. With GoDaddy it's a long distance call to reach them and they take forever. Start Logic has on-line support, they are very helpful and an 800 number you can call. Hope this helps, Regards

Is it because you only got the card today? Have you activated your credit card? This is the only thing I can think of that would be stopping you. If you have activated it leave it 48 hours and try again? If this still happens I'd try ringing your credit card company
