What is p.o. box 17316 salt lake city?

Unfortunately, as an AI language model, I don't have access to real-time or current information on any given PO box. However, I can provide general information on what a PO box is and how it works.

A PO (post office) box is a private mailbox that you can rent from the post office. Instead of using your home or business address for mail deliveries, you can provide the PO box address. This is especially useful when you don't want to share your personal or business address with others, or when you frequently move around.

In terms of location, PO boxes are typically located at the post office itself or in a separate area designated for PO boxes. For example, if you live in Salt Lake City, Utah, there may be a post office in the area that offers PO boxes for rent.

If you have more specific questions about PO boxes, you can contact your local post office or visit the official USPS (United States Postal Service) website for more information.
