Is It Okay To Put Something In Someone’s Mailbox?

No, you can’t put a note in a neighbor’s mailbox as it is prohibited and doing so could get you into trouble.

Giving the neighbor the note in person is preferable to place it in their mailbox.

The only person with authority to place something bearing postage in U.S. postal service mailboxes is a postal employee. Therefore, you must adhere to the proper postage procedure if you want to put messages in your neighbors’ mailboxes.

Postal workers are also permitted to empty mailboxes of foreign mail. As a result, if yours didn’t follow the proper postage procedure, it would be taken out of your neighbor’s mailbox.

USPS policy states that mailboxes may only be used to receive deliveries from the post office.

Do not attempt to use someone else’s mailbox if you do not have the owner’s permission to open it. Only postal service employees are permitted to put or remove mail from mailboxes.

In addition, if your neighbor wishes to take it further if the post box is on private property, you could face trespassing charges besides breaking federal law for posting things into a postbox without it passing through the system and the local postmaster.

Is It Illegal To Open Neighbor’s Mailbox?

The federal government owns the post mailbox, even if your neighbor purchased the mailbox. It is still the property of the federal government.

It matters not if you didn’t intend to steal, damage, or open mail, so opening your neighbor’s mailbox isn’t advised.

Because of the daily sending of millions of letters and packages, mailmen will inevitably make mix-ups.

The government has made it permissible to put misdelivered mail in the person’s mailbox, intended to offer a peaceful solution to this issue.

Therefore, you may put mail addressed to your neighbor in their mailbox when you receive mail intended for them.

You may only use your neighbor’s mailbox to deliver mail accidentally delivered to you instead of the intended recipient.

Therefore, leaving a note in your neighbor’s mailbox is not permitted. If you leave a note or even a flyer in your neighbor’s or anybody else’s mailbox, you could be held legally responsible and face a hefty fine.

What To Do With Mail Delivered to Wrong Address?

Do you frequently receive mail from your neighbor? Then you should contact the United States Postal Service (USPS). They will take note of your complaint and promptly address the problem of delivering to the wrong address.

The next step is to handle the mail you already have after dealing with USPS. Again, there are two approaches you can take.

Deliver It Yourself

By opening your neighbor’s mailbox, you can personally deliver the letter. No offense is being committed, and your neighbor might even be appreciative.

However, opening your neighbor’s mailbox appears suspicious, even if you’re only attempting to deliver their mail, so most people don’t want to do this.

It would be a more comfortable option for both you and your neighbor if you went to your neighbor, knocked on the door, and gave them their mail.

Alternatively, you might call or text them to ask them to pick up their mail at your house.

Return It to the Courier

If you don’t want to deliver the mail to your neighbor directly, simply mark it “Not at this address” on a sticky note and return it in a USPS Collection Box.

The courier will pick up the mail and deliver it to the proper destination.

If you continue to receive your neighbor’s mail but cannot contact USPS for any reason, you can also use this option. You might need to deliver multiple deliveries of the mail.

The courier will inform management that your neighbor’s mail is being delivered to the incorrect address, so it won’t be long until the error is fixed.

You can email or text them if you want to contact neighbors without calling.
