Does the box need to be attached to a post that is cemented into the ground or can it just stand wherever you put it?

Due to the location of my utilities, I couldn't cement mine *into* the ground. Instead, I bought a low square planter that fit the base inside it. I set the planter on a level tamped bed of gravel, then I drove a longish stake through the hole in the bottom. I put the base on a couple bricks to hold the base at the right height and then filled the planter with concrete. I ended up just cementing the base into the concrete since I had difficulty with the bolts. It holds well, doesn't tip, but could be moved if necessary for utility work. I'll eventually fill the post with cement/mortar to increase its strength, too.

if in dirt, pour a small slab of cement 1 (60lb) bag will do. let it dry & drill & set your anchors. or if your more advanced set the anchors in cement when wet, just remember if your off it will not line up with mailbox.

This mailbox does not require a base.
