You cannot truly block a specific person’s mail from coming to your house, but you can legally return it to the sender, and that is usually enough to stop the flow within a few weeks. What you cannot do is throw it away or destroy it. Mail addressed to someone else is protected by federal law even when it lands in your mailbox, so the right move is to route it back into the system with the correct marking.
Why You Cannot Just Throw It Out
Two federal statutes govern what you can do with mail addressed to another person. Under 18 U.S.C. § 1702, taking mail from a mailbox before it reaches the person it is addressed to, with the intent to interfere with their correspondence or pry into their affairs, is punishable by up to five years in prison and a fine.1Office of the Law Revision Counsel. 18 USC 1702 – Obstruction of Correspondence Under 18 U.S.C. § 1708, stealing or destroying mail from a mailbox or other authorized depository carries the same five-year maximum.2Office of the Law Revision Counsel. 18 USC 1708 – Theft or Receipt of Stolen Mail Matter Generally
Your mailbox is a federal mail depository. A letter sitting in it addressed to a former resident has not been delivered to the person it was directed to, which means opening it or trashing it can trigger either statute. The protection covers everything with a name on it, including what looks like junk. If it has someone else’s name, leave it sealed and send it back.
Returning Mail for a Previous Resident
The standard method costs nothing. Write “Not at This Address” on the envelope, leave the original address visible, and put it back in your mailbox with the flag up or drop it in a blue USPS collection box.3USPS. How Is Undeliverable and Misdelivered Mail Handled “Moved” or “Return to Sender” works too. Do not cross out or cover the original address.
If the same person’s letters keep showing up, leave a note inside your mailbox listing the names of everyone who actually lives there. Your carrier can use that list to catch misaddressed mail before it hits your box, and can mark the previous resident as “Moved, Left No Address” in their route records, which sets up automatic return-to-sender handling.
For stubborn cases, walk into your local post office. A clerk can add a formal note to your address record showing who does and does not receive mail there. That goes into the system rather than depending on one carrier reading a handwritten note.
The fastest fix for any single recurring sender is often the sender itself. Banks, insurers, and subscription services all have address-update processes, and one phone call to the company usually cuts off that stream faster than the return-to-sender route.
Returning Mail for a Deceased Person
Write “Deceased — Return to Sender” on the envelope and drop it back in the mail. That tells the sender to update its records.4USPS. How to Stop or Forward Mail for the Deceased
To forward a single item to an executor or family member, cross out your address, write “Forward to” and the new address on the front, and put it back in the mail.4USPS. How to Stop or Forward Mail for the Deceased
For a longer-term solution, the executor or administrator of the estate can file a change of address to redirect all of the deceased person’s mail. This has to be done at a post office in person, with documented proof of appointment as executor or administrator. A death certificate alone is not enough.4USPS. How to Stop or Forward Mail for the Deceased The forwarding runs for the standard 12 months.5USPS. Standard Forward Mail and Change of Address
Marketing offers and catalogs often keep coming after first-class mail stops. A family member or executor can register the deceased person on the Deceased Do Not Contact List through DMAchoice.org, which participating companies use to remove names from their lists. It will not eliminate every piece, but it thins the volume over time.
Refusing Mail Addressed to You
If a piece is addressed to you and you don’t want it, you can refuse delivery. Write “Refused” on the unopened envelope and put it back in your mailbox or a collection box. USPS returns it to the sender at no cost to you. The catch is that the mail has to be unopened. Once you open it and then try to refuse it, you owe the return postage.6Postal Explorer. Customer Support Ruling PS-177
A few categories cannot be sent back for free even when unopened, including Registered Mail, which requires postage on any return. For ordinary first-class letters, catalogs, and unopened packages, refusal works and costs nothing.
Forcing a Specific Sender to Stop
Federal law gives you one narrow tool to legally require a specific mailer to stop contacting you. Under 39 U.S.C. § 3008, if you receive an advertisement that you personally consider sexually provocative or erotically arousing, you can file USPS Form 1500 at any post office to get a prohibitory order against that sender.7Office of the Law Revision Counsel. 39 USC 3008 – Prohibition of Pandering Advertisements Bring the advertisement and its envelope. Your judgment on the content controls; USPS does not second-guess it.
The order takes effect 30 days after the sender receives it. From that point the sender has to stop all mailings to your address, delete your name from its lists, and refrain from selling or sharing your name with other mailers. If it violates the order, the Postal Service can refer the case to the Attorney General for federal court enforcement.7Office of the Law Revision Counsel. 39 USC 3008 – Prohibition of Pandering Advertisements
This tool exists only for advertisements offering something for sale. It does not cover personal letters, bills, legal notices, or general harassment by mail. If someone is sending you threatening or harassing letters, the right steps are a report to the Postal Inspection Service and, depending on severity, a restraining order through your local court.
What You Cannot Block: “Current Resident” Mail
Mail addressed to “Current Resident,” “Occupant,” “Postal Customer,” or “Householder” is addressed to whoever lives at your address. USPS treats it as properly delivered, and it will not be forwarded or returned to sender.8Postal Explorer. 602 Addressing – Section: 3.0 Use of Alternative Addressing Writing “Return to Sender” on it accomplishes nothing because USPS has no one to return it to.
Because that mail is addressed to you by virtue of living there, you can open it, read it, or recycle it as you like. None of the federal mail-tampering statutes apply. There is no USPS opt-out for this type of delivery.
Reducing Junk Mail and Prescreened Offers
Even mail addressed to you by name can be thinned with a couple of opt-out tools.
Pre-approved credit card and insurance offers come from the major credit bureaus sharing your information with lenders. To stop them, use OptOutPrescreen.com or call 1-888-567-8688. You will need your name, address, Social Security number, and date of birth. An online or phone request opts you out for five years. To make it permanent, sign and return the Permanent Opt-Out Election form you receive after the initial request.9Federal Trade Commission. What To Know About Prescreened Offers for Credit and Insurance Requests are processed within five days, though the offers may take several weeks to actually stop.
For catalogs, magazine offers, and other promotional mail, the DMAchoice mail preference service lets you opt out from companies that participate. Online registration costs $8 and lasts 10 years. Mail-in registration is $9, payable by check or money order to the Association of National Advertisers.10DMAchoice. DMAchoice Consumer Registration Not every sender participates, so the volume drops but does not disappear.
When to Report Mail Problems
Most misdelivery clears up with the return-to-sender method and a note for your carrier. If you suspect someone is deliberately stealing, opening, or destroying mail, that is a federal crime. The U.S. Postal Inspection Service handles those investigations. File a report at uspis.gov or call 1-877-876-2455.11United States Postal Inspection Service. Report a Crime If you catch someone actively stealing mail from your box, call 911 first.
For ongoing delivery errors that are not criminal, such as a carrier who keeps mixing up your box with a neighbor’s, start with your local post office and ask to speak with a supervisor. That is usually the fastest way to fix a route-level problem.
