At a glance
Mail delivery is a national network, but every mailbox is local.
Mailbox decisions often start at the edge of a driveway, yet they sit within a delivery system that reaches more than 170 million points nationwide. This page gathers the most useful current figures in one place for homeowners, writers, builders, and anyone researching curbside mail delivery.
For a mailbox installation, local conditions still matter. The USPS curbside mailbox standard says customers should contact their local post office before installing a mailbox to confirm the right placement and height for their route.

What it means
Start with the delivery requirements, then make the post your own.
USPS sets requirements for how a curbside mailbox works with delivery, not a single approved look for the post below it. Its published standard says it does not approve mailbox posts or regulate mounting accessories beyond the stated placement, clearance, and safety requirements.
That leaves room for a practical mailbox post that also belongs with the home, driveway, and landscape. For a custom cedar post, the useful starting details are the mailbox dimensions, door swing, the planned location, and any address, cap, or lighting details that need to be part of the design.
