What should a cardholder do if they suspect fraudulent activity on their GPC?

When a cardholder suspects fraudulent activity on their Government Purchase Card (GPC), it is critical to report it immediately to the program coordinator. This action is essential because the program coordinator is responsible for overseeing the GPC program and can initiate the necessary steps to investigate and resolve the matter. Prompt reporting helps protect the cardholder and the government from potential losses and unauthorized transactions.

Additionally, immediate reporting allows for quick corrective measures, such as freezing the card, conducting an investigation, and possibly recovering the funds. This aligns with the best practices for maintaining the security and integrity of the GPC system.

Other options, such as ignoring the activity or waiting until the next billing cycle, can exacerbate the situation by allowing further unauthorized transactions or complicating the recovery process. Contacting a supervisor may be a step, but it is not as effective as directly notifying the program coordinator, who is better positioned to handle fraudulent activity.
