A mailbox looks like the most harmless object on the street, a metal box on a post that holds bills, catalogs and the occasional birthday card. Federal law treats it with a good deal more seriousness than most people realize, and the holiday mailing season makes it a good moment to review the rules.
Three sections of the U.S. Code cover what can and cannot be done with mail and mailboxes. One of them carries up to five years in prison for taking mail before it is delivered, and another quietly catches a habit that plenty of well-meaning neighbors share.
Rule 1: Mail Cannot Be Taken or Opened Before the Addressee Gets It
Section 1702 of Title 18 covers anyone who takes a letter, postal card or package out of a post office or authorized mail depository, or from a letter or mail carrier, before it reaches the person it is addressed to. The offense also covers opening, hiding or destroying that mail, according to the text posted by Cornell Law School’s Legal Information Institute.
The key element is intent: the law applies when the act is done to obstruct correspondence or to pry into another person’s business or secrets. The penalty is a fine, up to five years in prison, or both. Readers who enjoy this kind of everyday legal trivia can find more in this list of everyday things that are against federal law, and the habit of sending actual letters belongs to the world of little rituals from the 80s and 90s that disappeared without much notice.
Rule 2: Stealing From a Mailbox or Keeping Stolen Mail Is a Crime
Section 1708 is the broader mail theft statute. It covers stealing, taking or removing mail or its contents from post offices, letter boxes, mail receptacles, mail routes or mail carriers, as well as obtaining them by fraud or deception, according to its text at Cornell. Checking the mailbox daily is one of the boomer habits that are making a comeback, and it is good protection against theft.
It also reaches mail left for collection on or near a collection box, and it covers anyone who buys, receives, hides or unlawfully possesses stolen mail while knowing it was stolen. The maximum matches Section 1702: up to five years in prison, a fine, or both. That last piece, which echoes the lessons in common illegal things many Americans have done without realizing, means a person who is handed stolen mail cannot simply say they did not take it, and the same caution applies to a stack of packages that appears at the door with no explanation. For porch safety during the holidays, there is also a guide to five things never to do with holiday packages left on the porch.
Rule 3: Unstamped Mail Does Not Belong in a Mailbox
Section 1725 is the one that surprises people. It makes it a federal offense to knowingly and willfully place mailable matter, such as account statements, circulars or sale bills, in a letter box established, approved or accepted by the Postal Service when no postage has been paid, with intent to avoid payment of lawful postage, according to Cornell’s version of the statute.
In plain terms, a homeowner or small business owner who drops flyers or unstamped bills without postage into a neighbor’s mailbox is on the wrong side of the law. The section provides a fine under Title 18, and each offense is punishable separately. The page does not list a jail term for this one, which makes it the mildest of the three, but it is still a federal rule. With holiday cards and packages about to fill mailboxes, the USPS Christmas shipping dates are a handy reminder of when the busiest mailing days arrive, and families packing for the season may like a look at luggage sets for holiday trips. The quirks of American mail habits make good company for odd American traditions that confuse the rest of the world.
What to Do When Mail Goes Missing
The U.S. Postal Inspection Service handles suspected mail theft and other mail-related crimes. Reports can be made online at report.uspis.gov or by phone at 1-877-876-2455, according to the Postal Inspection Service. If a crime is in progress, the page says to call 911 instead.
The same page notes that stolen personal information that could give someone access to financial accounts falls under identity theft, which has its own reporting option on the site, and that suspected tampering by postal employees should go to the USPS Office of Inspector General rather than the Inspection Service.
