Can a delivery confirmation piece be sent to a FPO address?

Delivery confirmation can be a bit tricky when it comes to military addresses, such as FPO (Fleet Post Office) addresses. The primary reason that sending a delivery confirmation piece to a FPO address is not allowed is that delivery confirmation is designed for domestic shipments within the United States. While FPO addresses may utilize USPS services, they are part of the international mailing system as they are linked to military postal services.

Items sent to FPO addresses generally involve different handling and processing compared to domestic deliveries, and the nature of military mail means that many of the tracking and confirmation services available for standard domestic shipments do not apply. The delivery confirmation service is typically used for packages that can be tracked and confirmed within the U.S. postal system, while FPO mail might not provide the same level of tracking capabilities.

Thus, acknowledging the unique requirements and limitations of military mail services, delivery confirmation is not available for items sent to FPO addresses.
