How to prevent drive by damage to our post mailbox?

several of my neighbors had the mail boxes put in stone or brick. Some did it themselves, others had professional help.

There are also covers you can purchase to help.

If you have a mailbox on a pole make sure the pole is steel

If the enclosure isn't an option right now, you can try putting reflective tape on the post.

Reflectors on the post are a good idea.. if the damage is accidental... and not deliberate. Painting your mailbox white or silver should also help. I am a retired Rural Mail Carrier... and have seen numerous ways to protect the box from damage..... a cage of galvanized water pipe can help protect the box... and a metal post will not break as easily as a wooden one.... and if you do not set the post in concrete... it may just pop out of the ground with minimal damage... You could set posts on either side of the box.. to take the damage first.. just be sure they are set back from the front of the box slightly (2 inches or so) so they do not restrict the mail carrier driving up to your mail box. You can also talk to your local Postmaster... your box may be situated where it can be set back off the side of the road enough that it will not be accidentally hit and the carrier can drive on the shoulder of the road to reach the box... but... only the Postmaster can give approval for that.

If you believe that the mail box is being hit or knocked over deliberately... contact your local Police or Sheriff's office and report the problem.... it is a crime. (we had one instance on my and a fellow carriers routes... over 400 boxes beaten with a bat or pipe in one night... the guys were caught and convicted)

Our whole subdivision was built with street side brick-and-mortar mailboxes. Almost thirty years later, many of the boxes are leaning some because of our shifting soil. But the only boxes actually damaged by drive-by vandals were more drive-crashes. Pickup trucks that run into the posts are usually damaged much more than the mailboxes. A few of the boxes have been completely rebuilt, some without the bricks around the boxes, but they are not as stable as the original. I suggest hiring a bricklayer to do the job right. ☺️
