If your card has been lost, stolen, or compromised, please contact Customer Support to have it marked lost or stolen immediately. You can also use the phone number on your card to report your card lost or stolen. If after business hours please use the automated phone system to report the card lost to prevent any unauthorized transactions. Once a card is marked lost or stolen, it cannot be used or reactivated.


Immediately contact customer service and request a replacement card, they can deactivate your card to prevent unauthorized use. We plan to build out functionality to deactivate your card within the BlockCard account; however - that does not presently exist.
