What form must a customer fill out to have their mail permanently forwarded to a new address?

The correct choice is the change of address form, which is specifically designed for customers who wish to have their mail permanently redirected to a new address. This form is crucial for ensuring that all types of mail—both personal and business—are sent to the updated location rather than the old one.

The change of address form captures essential information such as the customer’s previous address, new address, and the effective date of the change. By completing this form, customers can effectively manage their mail delivery and avoid missed correspondence.

While other options may seem plausible, they do not carry the specific designation that reflects the permanent nature of the change. The mail forwarding request might suggest a temporary solution rather than a permanent one. The forwarding certificate is more of a processing document rather than a form specifically for customers to designate an address change. Similarly, an address update form could imply a variety of updates that aren't specifically tied to mail forwarding. Thus, the change of address form is the formalized option that aligns with postal procedures for permanent mail delivery modifications.
