The United States Postal Service, or USPS, was founded in 1775 as a division of the government, which means USPS has the right to make legal restrictions.

Without Postage

According to postal regulations, no flyer or anything else mailable can be be put in a mailbox without proper postage.

With Postage

Even if you put a stamp on your flyer, it is still illegal to put the flyer in a mailbox unless it was mailed through the post office.

Collection Boxes

It is also illegal to affix flyers, stickers, or anything else to a United States Postal Service collection box.

Mail Slots

The only exception to the rule is a mail slot on a door or building. USPS regulations don't cover this, so you can insert a flyer into a mail slot.
