Each box has dispatch times printed on a label, and it will point you to the location for the latest pickup time in your area. Avoid depositing mail during the night, Sundays, and federal holidays.

Postal customers in some areas where home mail delivery is not offered may be eligible for a free post office box. First, you need to get Form 1093. It's available online and at your post office.

If you witness someone going into a collection box or mail delivery receptacle during non-postal work hours, contact your local police, and notify postal inspectors at 877-876-2455.
