Many people and businesses use P.O. boxes when they wish their home addresses to remain private. Some countries do not offer home delivery, and all mail must be addressed to the recipient's P.O. box. In the United States, there are areas where no door-to-door delivery is available, and residents must pick their mail up from a centralized group of boxes or at the local post office. The difference between these boxes and P.O. boxes is that mail addressed to a home address is automatically delivered to the correct box.

Companies such as United Parcel Service also offer P.O. boxes. Mail sent to UPS P.O. boxes also includes a street address.
