Mailbox Height & Placement – Official USPS Guidelines

Mailbox Height

Your mailbox height may not interest you most of the time, but rest assured that this is a very important topic to your mail carrier.  The USPS official mailbox regulations state that the mailbox should be positioned at a height between 41″ – 45″.

When measuring, take note that this height measurement is from the ground where your post is placed and not the road.  This is assuming that your post is on somewhat level ground.  If your post is on the downside of a hill, take this into consideration when measuring as this will position your box lower.  Also, notice that your measurement is to the bottom of the mailbox door, where the hinge is located.  This is the standard mailbox height that is most accessible from the mail carrier’s vehicle.  If you position the mailbox too high or too low, it may force the carrier to open their door to insert your mail.  This will not result in a happy mail carrier and we definitely want to keep those who are delivering our mail happy!  (See Unfriendly Mail Carrier)

 

Curb Placement

Equally as important, be sure the front edge of your mailbox is 6-8″ from the curb.  If you do not have a curb, place it 6-8″ from the edge of the road.  The distance you place the post from the road does not matter, it’s all about that front mailbox door.  This will enable your mail carrier to pull up to the mailbox, insert your mail, and proceed without having to exit the vehicle.

Which side of the road?

Your mailbox placement should always be on the right side of the road on one-way streets.  That is, if you are driving down the road, your mailbox should be on your right side.  This is the direction the mail carrier’s route will naturally take as they are traveling down the road.

In rural settings, look at other mailboxes on the same road.  You will want your mailbox on the same side as the others, even if it means you must cross the road to get your mail.

Don’t forget to keep trash cans and vehicles a good distance from your mailbox to allow your carrier enough free clearance.  They will greatly appreciate this little courtesy!

    The 1st diagram shows a requirement of 6 to 8″ from the curb to the mail box front with the door closed.
    The 2nd diagram shows a requirement of 6 to 8″ from the curb to the top of the door when opened.

    My mailbox has been the same box, on the very same post and at the same exact spot and height since 1976, thats 44 years since my father put it there as per postal requirements. They, nor I, since I’ve been living here now for 13 of those 44 years, have never had an issue with the mail carrier about the mailbox, however, since last summer 2019 I’ve noticed that almost every week , at least twice a week my door has been left opened, some others on the street have been having the same issue. I do not know who our carrier is as I have seen 3 different carriers over the past year.
    When I decided to make a complaint about the opened door then I received a recording stating my mailbox must be adjusted in height and placement.
    I fully believe this is retaliation for my complaint, Which by the way was Not to cause trouble But to have someone talk to the carrier about being more careful.
    I do not see why we have to adjust our mailbox after 44 years.
