The costly mailbox mistake that could leave New Jersey families without mail

📬 A damaged or unsafe mailbox could cause the USPS to stop delivering your mail until it's repaired.
🏠 New Jersey homeowners are responsible for maintaining curbside mailboxes that meet USPS safety and approval standards.
⚠️ An unapproved or improperly installed mailbox could leave your mail sitting at the post office—or headed back to the sender.

Make sure your mailbox meets USPS rules before your mail stops showing up

Most people don't think much about their mailbox until something goes wrong. But if your mailbox is damaged, unsafe or doesn't meet U.S. Postal Service standards, your mail carrier can legally stop delivering your mail.

That's the warning the USPS is emphasizing for homeowners, including thousands across New Jersey with curbside mailboxes. The rules are designed to protect mail carriers from injury, safeguard your mail from theft and weather, and keep delivery routes operating efficiently.

USPS mailbox requirements every New Jersey homeowner should know

If your mailbox sits at the curb, it must meet USPS specifications.

A USPS-approved curbside mailbox should:

📫 Be approved by the Postmaster General (look for the official PMG approval seal on manufactured curbside and locking mailboxes)
📫 Be sturdy, secure and in good working condition
📫 Protect mail from rain, snow and other weather
📫 Be mounted 41 to 45 inches above the road surface
📫 Be positioned 6 to 8 inches back from the curb
📫 Display your house number clearly where required
📫 Be large enough to accommodate your normal mail volume and small packages

Wall-mounted mailboxes generally do not require PMG approval, although door mail slots must meet minimum size requirements established by the Postal Service. Purpose-built locking mailboxes are permitted, but homeowners cannot simply add their own lock to a standard mailbox.

Damage that can stop mail delivery

The USPS also makes clear that carriers are not required to deliver mail to a mailbox that creates a safety or security risk.

You may need to repair or replace your mailbox if it has:

📫 A broken or missing door
📫 A damaged or missing lock on a locking mailbox
📫 Sharp or exposed metal edges
📫 A leaning or unstable post
📫 A mailbox that won't stay closed
📫 Damage that leaves mail exposed to weather or theft

If a mailbox is considered unsafe or unsecured, the Postal Service may suspend delivery until repairs are completed. Property owners are responsible for fixing or replacing private mailboxes.

If delivery is suspended, your mail is typically held at your local post office for a limited time and, if not claimed, it will be returned to the sender. If repairs will take longer, homeowners can request a free USPS Hold Mail service so mail is safely stored until delivery resumes.
