Because it is against Federal law to put anything in a mailbox, “on which no postage has been paid,” and if caught doing so a person could be fined up to $5,000 and an organization $10,000. Called the Mailbox Restriction Law, most countries do not have such legislation. But there is more. In the US, people receiving mail must pay for mailboxes, and these have to meet government specifications, or provide slots in their front doors through which postal carriers deliver mail. The Postal Service also “owns” our mailboxes and sets all the regulations involving them. Why?
If you go to the USPS website, the answer you get is that mailboxes could get so full with other items and papers that there would be no room to put mail into these. Second, the USPS says it wants “to ensure the integrity of our customer’s mailbox,” meaning only postal workers are allowed to place or remove mail from our mailboxes. History teaches us that while all this is true, there is always more to the story.
Use of First Class mail and package delivery expanded sharply in the early 1900s. Commercial users of postal services found the expense of postage higher than if they delivered their own mail, such as utility companies delivering water and telephone bills, newspapers the daily paper, and department stores their advertisements. So they began using their own carriers to deliver what otherwise would be largely First Class Mail, avoiding paying US postage. At the time, the biggest source of revenue for the Post Office was First Class Mail, and so private carriers were reducing the revenue coming into the postal agency. The US Post Office went to Congress and asked for a law to constrain this competition by making it against the law for anyone else to use a mailbox. In 1934, the New Deal Democratic Congress complied, as the postal system had enormous political power within the Democratic Party because every town and city had postal employees and they voted! The “mailbox restriction” law as it is often called (18 U.S.C. 1725) gave the Post Office what one government official observed was “a virtual monopoly over mailboxes.” Also, if it found any flyer or other item in the mailbox without postage, the Post Office could force the person putting it in there to pay postage for it even if not delivered by postal carriers.
Did it work? Yes, more or less. It seemed the Post Office had crushed its competition—at least for a while. Flyers, advertisements and newspapers continued to be delivered, just now stuck inside front doors, underneath welcome mats, and left on stoops and front yards. First Class mail still had to go through the Post Office.
Then came e-mail in the 1980s, followed by online shopping and banking in the 1990s and early 2000s. The volume of First Class mail dropped every year and, as the quantity dropped, the US Postal Service increased the price of a First Class stamp, which then motivated people to use more e-mail and to start paying their bills online, which further reduced the demand for First Class stamps. Increasingly, those utility companies that had created the problem for the Post Office in the first place made it increasingly possible to be paid online. Package delivery services, which offered better services and often cost less than the Post Office, became widely available in the 1990s. This took further business away from the Postal Service.
Until the arrival of the Internet and e-mail, the American postal system was the nation’s largest, most sophisticated information delivery infrastructure. Its role remained central to the movement of facts and all manner of paper-based reading materials, so its power was enormous. Its legacy is too. For example, a postal employee designed those round “tunnel type” mailboxes in 1915 used in front of homes and businesses. A century later they still are the most widely used. Today, the Postal Service still delivers to over 150 million addresses, but on average American adults have nearly two e-mail addresses, too, outnumbering their physical addresses. So still, the US Postal Service remains an important part of the nation’s information infrastructure.
In 2016, it handled 154 billion pieces of mail, employed 600,000 people, and operated out of over 31,000 post offices. The total revenue from the US mailing industry was $1.4 trillion. Of that, $71.4 billion came from the US Postal Service. First Class mail brought in $27.3 billion, still the biggest part of its revenues. As the Postal Service likes to point out, “If it were a private sector company, the US Postal Service would rank 39th in the 2016 Fortune 500.” The humble mailbox continues to be an integral part of our twenty-first century information infrastructure, even if the Post Office no longer has a lock on mail delivery. And you still cannot stuff mailboxes with neighborhood garage sale flyers or other things you want to conveniently leave a neighbor.

I am a former postal service officer who advocated for licensing the right to have access to mailboxes as a way to reduce delivery costs. The USPS has no interest in any form of deregulation.
Folks use the mailbox to leave their outgoing mail to be picked up.
Do you want the local babysitter, any lawn crews who are working in the area, Chinese restaurant employees, roofing installers etc etc etc to be reaching in your mailbox to stuff their flyers when you have outgoing mail, or mail that has already been delivered??? Mail in a USPS Mailbox is supposed to be secure. That WILL NOT be the case if anyone and their brother are reaching in there. Can you say “IDENTITY THEFT????
It seems that with all the privacy protection concerns regarding certain mail deliveries, the size of the package is still a problem. For deliveries to NBUs, first class or priority letter mail can be safely delivered to the small standard mailboxes or smaller cubicles used for condos or apartments. Mid-size packages can also be placed in larger designated cubicles that won’t fit in the standard smaller cubicles. For even larger packages, the carriers options include placing a note in the box that the package can be picked up at the post office branch; or, the USPS carriers simply drop the package on the porch or in front the owner’s door. With all the recent concerns regarding package thefts, isn’t there a better way to ensure the safety of a delivery these days? As I have experienced, many of these packages left at a door don’t even seem to be delivered to the rightful owner.
Just outside a large Oregon US post office is a paved area with several mailboxes on posts. These are used to train letter carriers in the practice of putting mail in the mailboxes of private homes. These mailboxes are plain and do not carry the words “U.S. MAIL”.
I opened one of thes mail boxes the other day, to see what training materials might be in
a practice mail box.
There was nothing inside, other than a handwritten post-it note that read “look both ways” “turn tires”.
A post office employee told me that I had just broken the law and coud be charged with an offence.
Is that true? Am I guilty of a federal offence?
I’m in Baltimore city, md. I tried to mail letters and the mail boxes on 2 of my closest corners were almost closed. If I put mail in them, will it be delivered? Is this purposely done for protection or is it due to vandalism?
Some post offices are telling me I can’t put something on the mailbox…I have read nothing about putting something on the mailbox…is that actually true?
