Wall-Mounted vs Post-Mounted Mailboxes
The choice between wall-mounted and post-mounted isn't a style preference — it's determined by how your mail gets delivered. Pick the wrong type and your carrier can't deliver. Pick the right one and it becomes the easiest upgrade you'll make to your home's exterior.
Here's exactly how to decide.
Your delivery method decides for you
This is the only question that matters: does your mail carrier leave the vehicle or walk to your door?
If your carrier stays in the vehicle and delivers from the road, you need a post-mounted mailbox. This is the standard delivery method in most suburban, rural, and newly developed neighborhoods across the United States. The mailbox must be installed on a freestanding post at the curb so the carrier can reach it from the driver's side window without leaving the vehicle.
If your carrier walks to your front door, you can use a wall-mounted mailbox. Wall-mounted delivery is common in urban areas, townhomes, and older suburban neighborhoods where carriers walk their routes. The mailbox mounts directly to your exterior wall beside the entryway.
Not sure which applies? Watch your carrier deliver one day. Or call your local USPS office — they'll tell you immediately.
Wall-mounted mailboxes: what to know
A wall-mounted mailbox attaches directly to your home — beside the front door, on a porch column, or near the entryway. No post, no ground work, no concrete.
Best for:
- Homes with door-to-door mail delivery
- Urban properties, townhomes, condos
- Tight facades where a post would crowd the yard
- Homeowners who want a clean, architectural look integrated with the house
Installation: Mount directly to any exterior surface — wood, brick, stucco, stone, vinyl siding. Most installations take 15–20 minutes with a drill. No digging, no post setting, no concrete curing.
Sizing: Wall-mounted mailboxes range from slim vertical profiles (like the City B at 7.125" wide) to full-width models (like the Mitch at 14.625" wide). Choose based on your wall space and mail volume — most homeowners need at least USPS size C2 to comfortably fit magazines, catalogs, and small packages.
USPS requirements: The USPS does not mandate specific dimensions for wall-mounted mailboxes, but the box must be large enough to hold a normal day's mail volume and positioned where the carrier can access it safely. Height should be 41–45 inches from the ground. For full placement specifications, see USPS Mailbox Delivery Requirements.
Post-mounted mailboxes: what to know
A post-mounted mailbox sits on a freestanding post near the road, positioned for curbside delivery. The carrier delivers from their vehicle without leaving the road.
Best for:
- Homes with curbside mail delivery (most suburban and rural US addresses)
- Properties set back from the road with long driveways
- Neighborhoods where all mailboxes are at the curb
- HOA communities with standardized mailbox placement
Installation: Requires a post anchored into the ground — either a 4×4 wood post or an aluminum mailbox post. You'll need to dig a hole (typically 18–24" deep), set the post in gravel or concrete, and mount the mailbox on top. Allow concrete to cure 24–48 hours before mounting.
Sizing: Post-mounted mailboxes are typically USPS size C2 or larger. Wider models like the Jeremy (the widest in the Vsons lineup) hold small-to-medium packages and multiple days of mail — useful if you travel or receive frequent deliveries.
USPS requirements: The bottom of the mailbox must be 41–45 inches from the road surface. The post must be set 6–8 inches back from the curb. The mailbox must be on the right-hand side of the road, facing outward. Post-mounted mailboxes must bear the Postmaster General's seal of approval or meet PMG size standards. For the full breakdown, see USPS Mailbox Delivery Requirements.

Material matters more than mounting type
Whether you choose wall-mounted or post-mounted, the material determines how long your mailbox lasts. Mounting type doesn't change this equation — a cheap steel mailbox will rust regardless of where you put it.
Powder-coated aluminum is the most durable option for either mounting type. Aluminum cannot rust — ever. Not in coastal environments, not after 20 winters, not in the Gulf humidity. Premium aluminum mailboxes use 14-gauge 5052-H32 alloy with an industrial powder coat that resists UV, scratches, and fading.
304 stainless steel delivers a brushed metal aesthetic that aluminum can't replicate. It performs well in most residential environments and lasts decades with minimal care. One caveat: 304 stainless can develop surface spots from salt exposure — ocean air or road de-icing salt.
316L marine-grade stainless steel is required for homes within one mile of saltwater. Contains molybdenum for superior resistance to salt spray and chlorides.
Avoid: Mild steel, thin-gauge metals, and plastic. These are the materials in $30–$60 big-box mailboxes. They rust at every seam within 2–3 years.

Security: locking options for both types
Mail theft affects millions of U.S. households every year. Both wall-mounted and post-mounted mailboxes are available with integrated locking systems.
A locking mailbox allows your carrier to deliver mail through the front opening as normal. Once the door closes, it locks automatically and can only be opened with your key.

Frequently asked questions
Can I switch from post-mounted to wall-mounted (or vice versa)? Only if your delivery method supports it. If your carrier currently delivers curbside, you cannot switch to wall-mounted without USPS approval — and approval is rare. If your carrier walks to the door, you can use wall-mounted. Call your local post office before making any changes.
Which type is better for modern homes? Both work. Wall-mounted mailboxes integrate more seamlessly with modern facades — they become part of the architecture rather than a separate object in the yard. Post-mounted mailboxes with clean lines and matte finishes (like the Anthony or Jeremy in black aluminum) complement modern homes where curbside delivery is required.
Do I need a specific post for a post-mounted mailbox? Vsons post-mounted mailboxes are compatible with Vsons aluminum posts or standard 4×4 wood posts. The Federal Highway Administration recommends a 4×4 wood support or 2"-diameter steel/aluminum pipe — avoid heavy concrete posts or unyielding metal structures that won't give if hit by a vehicle.
Which type is more secure? Neither is inherently more secure. Security depends on whether your mailbox has a lock, not on where it's mounted. That said, post-mounted mailboxes at the curb are more accessible to passersby — so if mail theft is a concern in your area, a locking post-mounted mailbox is especially worth considering.
What if I'm building a new home? Ask your builder what delivery method the neighborhood uses. New developments almost always use curbside delivery, which means post-mounted. Your HOA may also have specific requirements for mailbox style, color, and placement. For bulk orders, see HOA & Bulk Orders.
