What is the service that allows a customer to obtain street-addressed mail from the PO Box?

The correct service that allows a customer to obtain street-addressed mail from the PO Box is known as Firm Holdout. This service enables customers who mainly receive their mail at a PO Box to also receive other types of mail that may not typically be sent to a PO Box due to its street-addressed format. Firm Holdout is particularly useful for businesses needing a consistent address for correspondence and packages, ensuring that all mail—regardless of its address format—can be collected from the PO Box.

Street Delivery Service generally refers to the standard delivery of mail directly to a street address rather than facilitating access for PO Box customers. P.O. Box Access can imply customers being able to access their PO Box; however, it does not specifically address the retrieval of street-addressed mail. Mailbox Retrieval is not a recognized USPS service and does not pertain to the specific context of receiving street-addressed mail at a PO Box. Therefore, Firm Holdout is the precise term for this service arrangement.
