Can a Canadian resident rent a US Post Office Box?

Oh, dude, can a Canadian resident rent a US Post Office Box? Well, technically, yes, they can, but like, there are some rules and regulations they gotta follow. It's not like they can just waltz in and be like, "Hey, give me that PO box, eh?" They need to provide valid ID and proof of address in the US, so it's not exactly a walk in the park, you know what I mean?
