What should a customer provide to maintain a temporary forward for more than the original period allowed?

To maintain a temporary forward for more than the original period allowed, the customer must provide a request for renewal. This process is essential because temporary forwarding allows mail to be redirected to a new address for a specified period, which is often limited. If a customer needs to extend this period, a formal request is necessary to ensure that the postal service is aware of the ongoing need for the forwarding service.

Submitting a request for renewal allows the Postal Service to document the customer's intent and ensure that mail continues to be delivered appropriately without interruption. It also serves as a way for the customer to confirm their continued absence and need for mail forwarding, ensuring that the service remains efficient and accurate. Additionally, the renewal process often includes verifying that the customer still resides at the original address and that the forwarding information is up to date. This helps maintain the integrity and security of mail handling practices.
