can priority mail be sent to po box

can priority mail be sent to po box is a frequent USPS-related question. The answer is yes—Priority Mail can be delivered to PO Boxes, just like standard First-Class Mail. USPS has full access to internal PO Boxes, allowing faster and more secure delivery for packages. This is useful for customers who don’t have home delivery or prefer mail to be held in a central location. PO Boxes are also supported for Priority Mail Express and other services.
