When should cardholders report an unauthorized charge to US Bank?

Cardholders should report an unauthorized charge to US Bank immediately upon discovery to ensure prompt response to potential fraud. Reporting as soon as the unauthorized transaction is noticed minimizes the risk of further unauthorized activity and helps in the investigation process. This immediate notification allows US Bank to take necessary actions, such as blocking the card or investigating the charge, which can prevent additional charges from occurring and protect the account holder's finances.

Timely reporting is also essential because delays can complicate the resolution of the issue and may lead to the cardholder facing liability for fraudulent charges, particularly if the incident is not reported promptly. This proactive measure helps safeguard both the cardholder and the institution against potential losses related to fraud.
