USPS will not deliver mail to a broken mailbox once a carrier or postmaster decides the box is unsafe, insecure, or too damaged to protect what’s inside. Delivery gets suspended, your mail sits at the local post office, and service only restarts after you repair or replace the box to postal standards and let your post office know it’s ready. Most fixes are cheap, and getting back on the route is straightforward once you know what USPS is looking for.
When USPS Stops Delivering
Carriers are trained to flag mailbox problems. When they do, the postmaster sends a formal notice: PS Form 1507 (“Request to Provide Mail Receptacle”) on city routes, or PS Form 4056 (“Your Mailbox Needs Attention”) on rural and highway contract routes. The form tells you what’s wrong and what to fix. If you don’t act on the notice, the postmaster can withdraw delivery service entirely with the district manager’s approval.1United States Postal Service. Postal Operations Manual Section 623 – Withdrawal of Delivery Service
The problems that typically trigger suspension fall into a few categories:
- Structural damage: a broken door or lid that won’t close, a collapsed or leaning post, or sharp edges that could cut the carrier’s hands.
- Security failures: a latch or lock that no longer holds, leaving mail exposed to weather or theft.
- Access problems: overgrown bushes blocking the box, a post knocked out of reach, or cars regularly parked in front of a curbside box.
- Safety hazards in the delivery path: an unrestrained dog will get delivery suspended for the entire area the animal can reach, not just your address.2United States Postal Service. Information for All Mail Carriers
Road conditions count too. If damage or construction keeps the delivery vehicle from reaching a stretch of mailboxes, the postmaster can withdraw service for that stretch until the road is repaired.1United States Postal Service. Postal Operations Manual Section 623 – Withdrawal of Delivery Service
What Happens to Your Mail While Delivery Is Suspended
Your mail doesn’t vanish during a suspension. It piles up at your local post office, and you’ll need to pick it up in person. Bring a valid photo ID: driver’s license, state ID, passport, or military ID.3United States Postal Service. DMM Revision – Required Forms of Identification The post office won’t hold it forever. Ignore the problem long enough and undeliverable mail gets returned to the sender.
If you know your repair will take a few days, request USPS Hold Mail service before it becomes an issue. It keeps everything at the post office for 3 to 30 days at no charge.4United States Postal Service. USPS Hold Mail Service5United States Postal Service. PO Boxes6United States Postal Service.

What Your Mailbox Has to Meet Before Delivery Resumes
The standards for a curbside mailbox are specific. The bottom of the box, or the mail slot on a locking design, has to sit 41 to 45 inches above the road surface, and the box should be set back 6 to 8 inches from the curb or road edge.7United States Postal Service. How to Install a Mailbox Your house or apartment number has to be visible on the box. If there’s no raised curb along your road, ask your local postmaster where the box should go.
Any curbside mailbox sold at retail must carry the Postmaster General’s seal of approval, which certifies it meets USPS size and construction standards. Build your own, and you have to show the plans or the finished box to your postmaster for approval before installing it.7United States Postal Service. How to Install a Mailbox A full-service curbside box also carries a carrier signal flag on the right side. The flag has to contrast with the box color; fluorescent orange is preferred, and green, brown, white, yellow, and blue are not allowed.8United States Postal Service. U.S. Postal Service Standard Mailboxes, Curbside
In winter, a compliant box still won’t earn delivery if the carrier can’t safely reach it. USPS expects the approach cleared of snow and ice so the truck can pull up, deliver, and drive away without backing up or leaving the vehicle. On foot-delivery routes, walkways, steps, and handrails all need to be clear, and heavy snow or ice on overhanging branches or roof edges should be knocked down before it falls on the carrier.9United States Postal Service.

Getting Delivery Restarted
The fastest path back to normal delivery is to fix what the notice identifies, then tell your post office it’s done.
- Read the notice carefully. Sometimes it’s a loose door hinge, not a full replacement.
- Make the repair, or install a new box that carries the Postmaster General’s seal of approval. Set it at 41 to 45 inches high and 6 to 8 inches back from the curb, and put your house number on it.7United States Postal Service. How to Install a Mailbox
- Check any local rules. Homeowner associations and municipalities sometimes have style, color, or placement rules on top of the USPS requirements. Local rules don’t override postal standards, so you have to satisfy both.
- Call or visit your post office to say the repair is done. The carrier verifies compliance on the next route, and delivery resumes from there.
Who Pays for the Repair
If you own your home, the mailbox is yours to fix. USPS does not repair personal mailboxes. Renters, apartment tenants, and condo residents should go to the property owner, landlord, or association, which handles maintenance and repairs on shared and cluster boxes, including replacing lost keys.10United States Postal Service. Mailboxes – The Basics
A basic curbside mailbox and post usually runs between $60 and $400 installed, depending on materials and whether you hire the work out. A standard PMG-approved metal mailbox on a wooden or metal post sits at the low end of that range. Brick or stone surrounds cost considerably more.
Snowplows are one of the most common causes of winter mailbox damage. Many local governments will reimburse you or provide a replacement if a municipal plow actually struck the box, but usually only when the box was properly installed and the plow itself (not just thrown snow) made contact. Claims typically go through your city or county public works department with a receipt. Policies and reimbursement caps vary widely, so check locally before you buy.
If Your Mailbox Was Vandalized
A mailbox in use for mail delivery is federal property, and deliberately damaging one is a federal offense. Under 18 U.S.C. § 1705, willfully or maliciously destroying, tearing down, or defacing a mailbox or mail inside carries up to three years in prison, a fine, or both.11Office of the Law Revision Counsel. 18 U.S. Code 1705 – Destruction of Letter Boxes or Mail That covers curbside boxes, apartment cluster boxes, mail slots, and PO boxes. Accidental damage, like backing a car into a neighbor’s post, doesn’t meet the “willful or malicious” standard.
Stealing mail from a mailbox is a separate offense under 18 U.S.C. § 1708 and carries up to five years in prison.12Office of the Law Revision Counsel. 18 USC 1708 – Theft or Receipt of Stolen Mail Matter Generally That connection is part of why USPS treats a broken box as a delivery-stopping problem: a door that won’t close makes theft trivial.
Report vandalism to the U.S. Postal Inspection Service at uspis.gov, which handles mail crimes by members of the public. Mail crimes involving a postal employee or contractor go to the USPS Office of Inspector General instead.13United States Postal Service Office of Inspector General.
