Note: Each credit card entry that appears on the Manage Credit Cards page represents credit card information that was entered in at the time of purchase. The same information could have been entered into our system more than once at different times, creating redundant entries.
All entries that have their 'Delete' option greyed out are in active use and should be updated accordingly. Which credit card information is being used to renew services can be managed through My Account -> Billing & Invoices > Manage Automatic Payments. Credit card information that is not in use will have the Delete option available in Manage Credit Cards, and can be retained or deleted as you see fit.
