Title: Post-office box
Passage: Some private companies (e.g., United Parcel Service (UPS) and commercial mail receiving agencies) also offer similar services of renting a mailbox in a public location. The difference with an official PO box is that mail sent there is addressed to a street address (along with the box number), instead of just addressed to ``PO Box CSX''.
Question: can a po box have a street address
Answer: yes
