I have us paypal account I try to add my us bank account to it many times but paypal refuse operation : (We were unable to process your bank account registration at this time. We apologize for the inconvenience. Please try again at a later date.) so any body can help me ?
Are you in the US? Just wondering because generally, when someone adds "US" before service "X", they're not from it. If not, that may possibly be the reason but it would be a good idea to call/email them.
If you bought the US Bank account from somewhere then you may face problems especially if that Bank account does not actually have a 'bank' behind it. I am pretty sure that Paypal knows all the approved banks in the US and from what I understand, they do not go about selling bank accounts just like that. You will need to apply for a real one over the counter or by some other means but by providing all the documentations which they require.
