What service allows a customer receiving over 50 letters to collect their mail from a PO Box?

Firm Holdout is the service designed for customers who receive a high volume of mail, typically over 50 letters, allowing them to collect their mail directly from a PO Box instead of having it delivered to their street address. This service is beneficial for businesses or organizations that may want to manage their mail more efficiently. The Firm Holdout option accommodates the needs of customers who may not have sufficient mail delivery infrastructure or prefer to centralize their mail collection at a designated location.

The other services listed, such as Temporary Forwarding, Premium Forwarding, and Mail Hold Service, serve different purposes. Temporary Forwarding allows mail to be temporarily sent to a new address; Premium Forwarding provides a more complete forwarding service for a set period; and Mail Hold Service holds mail at the Post Office for a specified duration but does not specifically address the collection of large volumes of mail similar to Firm Holdout.
