If The Local Postmaster Is The Owner

The rules will be changed if the local postmaster is the owner of the mailbox. It requires many steps to change your mailbox. The following are some of them:

– At first, you need to go to the post office that is closer to your home with residential proof that you live there.

– Once you have shown them your residency proof, you will be assigned a postmaster who will come to visit the mailbox at your home.

– The postmaster will charge about 40 dollars and he will give you all the required information about changing the mailbox.

– After changing the mailbox, again you have to go to the post office and write a form that you have changed it.

– Only the postmaster or someone from the post office can change the mailbox, so they will be owning the keys afterwards they change it for you.

So, it is quite understandable that if the postmaster is the owner of the mailbox, it will require a huge procedure to follow. It is better if you install your personal mailbox to avoid all such issues.

When Is It A Crime To Break The Mailbox Lock?

So far from our discussion, we got this point that changing or replacing a personal mailbox is never a crime and you are free to do it anytime you want. But the question here is when it is taken as a crime to break the lock of the mailbox.

At first, if the mailbox is not your personal, it will be taken as a crime if you don’t mention your local post office about this. But if you inform them and they send someone with you to change it, then you are good to change it.

It was taken as a crime some time back but now it is all okay to change a personal mailbox and keeping the keys. Just take care of the loose parts and keep a straight and clear way towards the mailbox. It will give other people a good idea of doing the same.


Changing your personal mailbox, or the lock of a mailbox is totally fine. You can do it by yourself. But if the mailbox is not yours, but the post office’s, you need to have permission.
