If you have a prepaid credit card, there are a few things you can do to cancel it.

  1. Call the card issuer and ask to be removed from the account. This will usually require providing your name, address, and account number.
  2. Write a letter to the card issuer explaining why you no longer want your account open and requesting that your card be cancelled.
  3. Post a notice on the door of your house or workplace letting people know that you no longer have an account and asking them to stop using your card.
