They aren’t true mailboxes any more. They’ve been repurposed. I doubt the Postmaster General would be very happy to find out their new use.

The first Doggiebox (1, 2 & 3) was found in the 1800 Block of S. Sunburst Dr. The second Doggiebox (6, 7 & 8) was found in the 1500 Block of S. Desert Vista Dr. When you see the photos you’ll understand why there isn't an address. Both are in the same neighborhood, so I’m guessing they were put there by the Neighborhood Association.
