It depends on if a new card would share the same bank identification number.   The first digits of your credit card identify what bank issues the card.    Looking over the list on wikipedia, some banks have multiple numbers based on card type.  If that is the case, you would need a new number.

I am using Magento Enterprise 1.14.0.1 
I have Fedex Shiiping method activated and have entered in the information for production that was provided and confirmed by Fedex to be correct for the account ID, Meter, Password, and the key. I have sandbox set to no since the credentials are for production. I have a Max package weight set packaging set to "Your Packaging" and the "drop off" set to regular pickup as we have a driver that comes everyday.

My issue is when I click the button to create a shipment and then enter the total weight and then add the product and click the check box and add the product to the shipment. I then click OK and get an error message that says

Insufficient information to create shipping label(s). Please verify your Store Information and Shipping Settings.

I do not know what to check to fix this.
