In other words; naming people who can receive mail in a PO Box is just a waste of time?
Of course not, think a little and stop with the knee jerk reactions of a one eyed biased Kook, if a letter has been mangled for whatever reason there may be a need to gather more information from a complete other source, so the letter can be delivered.
Anyway getting back to reality, "Return to Sender" isn't some vague phrase invented by the WC. LOL!
In the following Post Office rubber stamps for "Return to Sender" is there any option that says that "the name on the application doesn't match"
