When your Cash App card is locked, it means that your card cannot be used to make purchases or withdrawals. It is important to note that a locked Cash App card does not necessarily mean there has been suspicious activity on the account; it could simply mean that you have forgotten your pin code and need to reset it. In order to unlock your Cash App card, you must contact their customer service team and provide them with some basic information such as the last four digits of the associated bank account number or debit/credit card details that were used when setting up the original cash app account. Once these are verified, they will then send you an email containing instructions on how to unlock your Cash App Card.
