Single-Use Card

A single-use card is a virtual payment card designed to be used for one transaction or one binding, then discarded. Once charged or attached, it is closed or its details become worthless, so a leaked number can't be reused. In media buying it's the disposable end of the virtual-card spectrum — issued in seconds, burned without regret, and never shared across assets.

Buyers lean on single-use cards to isolate risk per ad account: when Facebook flags a card, only one account is exposed, and the platform can't link accounts through a shared payment method. The pitfall is rebilling — subscriptions and delayed ad-spend charges fail once the card is dead, which can trigger unpaid-balance bans. Keep longer-lived cards for anything that charges more than once.
