What fee do customers have to pay to regain access to their PO Box after the 10th day?

When a customer does not renew their PO Box rental and fails to do so within a 10-day grace period, they must pay a fee to regain access to their PO Box. The correct fee for regaining access after this period is $21. This amount is standard practice and is enforced to encourage timely renewals while also providing a clear monetary consequence for delays.

This fee structure is designed to maintain the operational efficiency of the USPS and ensure that PO Boxes are managed in a way that benefits all customers. By charging a specific amount, the USPS can better manage its resources while also reminding customers of the importance of adherence to renewal deadlines.
