Mailbox with Post Packages

How to Choose a Mailbox With a Post for Your Home

A mailbox with post included solves a problem that catalog shopping creates: two parts that don’t actually fit together. When you buy a mailbox and post combo, the mounting pattern, post diameter and arm length are matched at the factory instead of guessed at on your driveway.

Buy them separately and you risk mismatched mounting hole patterns, a post platform narrower than the box floor, or an arm that puts the box outside your carrier’s reach from the road. None of these show up until installation day, when they’re expensive to fix.

That’s why we sell mailboxes with post as matched sets, not loose parts. Browse all 407 of our mailbox and post combos from fourteen manufacturers, each built to pair with the post it ships beside. For an outdoor mailbox with post that survives installation and years of daily use, start with a set.

What Size Mailbox and Post Do You Need?

Most curbside mail fits comfortably in any of our 407 combos, whether that’s a compact option for letters and magazines or a large mailbox with post built for catalogs and rolled newspapers. If you regularly receive packages alongside your mail, filter by capacity: 337 of our combos are tagged for small packages, and 7 for large packages, so an extra large mailbox with post is easy to spot in the grid, or look at our dedicated parcel and drop box mailboxes if parcels arrive more often than not. Exact dimensions vary by brand and aren’t standardized across collections; the Whitehall Custom Capitol mailbox, for example, measures 13 × 9.625 × 20.375 in. Always confirm the exact figures on the individual product page before you order.

How Our Post Materials Hold Up in Your Climate

A metal mailbox with post has to survive whatever your climate throws at it, from road salt and freeze-thaw cycles in the Northeast to salt air and humidity along the Gulf and Atlantic coasts, and the material you choose matters more than the finish color on top of it. If you’re within a few miles of saltwater, an aluminum mailbox with post resists corrosion in a way untreated steel simply can’t, and it won’t need repainting after a season of storms rolls through. Inland, where road salt is seasonal rather than constant, a galvanized or powder-coated steel post holds up fine and costs less upfront. Brass sits apart from the rest: it’s the pick for traditional and formal architecture rather than climate resistance alone, and it will develop a natural patina over time unless it’s lacquered. The table below breaks down which material fits which climate, along with roughly how much upkeep to expect once it’s installed.

Material	Best For	Maintenance
Steel	Budget-conscious, inland installs — our largest in-stock material	Low; touch up chips promptly, rinse off road salt in winter
Cast Aluminum	Coastal and humid climates	Very low; won’t rust
Stainless Steel	High-security, coastal installs	Low; occasional wipe-down
Aluminum	Coastal, low-maintenance buyers	Very low; lightweight, won’t oxidize
Galvanized Steel	A small in-stock selection — confirm availability before specifying	Low; rinse off road salt in winter
Brass	Traditional, formal architecture	Moderate; will patina unless lacquered

Do You Need a Locking Mailbox and Post?

Mail theft is the single biggest reason buyers upgrade to a locking mailbox with post. Of our 407 combos, 275 include a lock and 53 are explicitly tagged non-locking; the rest vary by collection, so check the individual product page. Security comes down to one of four mechanisms:

• Cam lock: a keyed cylinder lock, the most common option and easy to rekey
• Anti-pry latch: reinforces the door against forced entry
• Fishing-proof slot: a mail slot too narrow to fish outgoing mail out with a hook or wire
• Combination lock: no key to lose, code-based access for shared or rental properties

A lockable mailbox with post costs more upfront than an open box, but if you’ve ever had a package or a check pulled from an unlocked mailbox, the difference pays for itself the first time it stops a repeat. Most buyers who’ve been hit once never go back to an open door.

How to Pick Your Mailbox Color and Finish

Color should match the hardware already on your house, not just the box on its own.

• Black: a black mailbox with post pairs with almost any exterior and hides scuffs well, which is part of why it’s the top seller across nearly every collection we carry
• Bronze: a bronze mailbox with post reads as traditional, especially set against brick or stone
• White: a white mailbox with post brightens a farmhouse or coastal exterior without looking stark
• Copper: a copper mailbox with post develops a natural patina over time; if you already like that aged look, browse our antique and vintage mailboxes
• Red: a red mailbox with post is the classic curbside look, best on simple architecture where it can stand out on its own

A black metal mailbox with post is the single most requested combination we sell, largely because it disappears into almost any color scheme instead of fighting it.

Accessories Included With Your Combo

Most of our mailbox and post combos ship with hardware to finish the look, not just the function.

• Finial: a decorative cap for the post top, available in several styles per collection
• Post cuff: a trim ring that hides the post’s base for a finished look
• Address panel: mounts on the post or box for street-visible numbers
• Newspaper holder: a side tube that keeps papers dry and off the ground
• Flags: standard USPS-compliant flags, with decorative alternatives available on select collections.

Lost or damaged a piece? Our replacement mailbox parts are sold separately and matched to your original collection, so you’re not stuck replacing the whole set over one broken finial.

Unique Mailbox and Post Styles We Carry for Every Home

Style should say something about the house it sits in front of, so we group our decorative mailboxes with post by the architecture they’re built to match.

• Modern: clean lines, often powder-coated black or matte finishes
• Victorian: scrollwork and finials for period homes
• Traditional: the shape most people picture when they hear “mailbox,” and it works almost anywhere
• Colonial: boxy and symmetrical, built for brick and clapboard exteriors
• Decorative: ornamental detailing and finials for homes that want more visual presence than a traditional or colonial profile offers.

If your home leans farmhouse or cabin instead, browse our rustic mailboxes for weathered textures and darker metals that suit those exteriors better than the four above. And if you want something smaller and more playful rather than strictly period-accurate, a cute mailbox with post in a compact size works well on shorter driveways and starter homes, where a large combo would look out of scale.

Browse the full range and filter by style, material or price to find the combo that fits.

Which Mailbox and Post Combo Is the Best for Your Home

There’s no single best mailbox and post combo, only the one that fits your house, your climate and how much security you want. If you’re comparing options, the best mailbox with post for a coastal property looks different from the best mailbox with post for a landlocked HOA development, and neither is objectively better than the other. 

We carry 407 combos across fourteen manufacturers, more of the best mailboxes with post than any specialist in this category, so instead of naming a winner, here’s how five of our top-selling collections compare.

Collection	Material	Locking	Finish Options	Best Suited To
Whitehall Capitol	Cast aluminum	Non-locking	5 powder-coat colors	Traditional and colonial homes wanting decorative detail
Gaines Keystone	Cast aluminum	Optional	13 finishes	Value-focused buyers who still want a name brand
Imperial	Cast aluminum	Non-locking	9 finishes	Coastal installs and high-traffic streets
Mail Manager Pro	Powder-coated steel	Yes, patented anti-pry	1 finish (black powder coat)	Buyers who prioritize security above style
Architectural Centennial	Galvanized steel	Non-locking	2 finishes (Black, Rubbed Bronze)	Buyers who want extra parcel capacity in a clean, architectural profile

If decorative detail matters most, Whitehall Custom Capitol Mailbox and Post Package. If security matters most, Mail Manager Pro. If you’re outfitting a coastal property, start with Imperial. However you land, browsing our full brand lineup shows you every combo option each manufacturer carries, not just these five.

Replacing an Old Post or Starting from Scratch?

If you’re shopping for a new mailbox and post, the first question is whether you need both parts or just one. A quick check tells you which:

• Check the anchor: push the post firmly at the top. If it moves at ground level, the anchor has failed and you’ll need a new post, or more often, a full combo once the mounting pattern is factored in.
• Box damaged, post solid: if the post is sound but the box is dented, rusted through, or storm-damaged, you likely just need a mailbox without a post.
• Post failed, box fine: if the box is in good shape but the post is the problem, browse posts sold separately.

One thing to know before you go the mix-and-match route: an existing post rarely matches a new box’s mounting pattern. That’s why most replacements end up as a mailbox with post included rather than two separate purchases.

Should You Choose a Post Mounted Mailbox or a Wall Mounted Mailbox?

The deciding factor isn’t style, it’s how your carrier delivers. If your route is driven, a curbside mailbox with post lets the carrier reach your box from the vehicle without getting out. Post mounted mailboxes suit homes with a driveway, a setback from the road, or a rural route.

If your carrier walks the route and delivers door to door, or you’re on a tight urban lot with little to no setback, a wall mounted mailbox at your entry makes more sense than a post mount mailbox out at the curb. Not sure which applies? Check your current mailbox location; USPS rarely changes an established route.

Our Multi-Unit Mailbox and Post Sets

Shared driveways, duplexes, and HOA developments need mail delivery that stays uniform across every unit. We carry 16 dual, triple, and quad mailbox and post combos (8 twin, 4 triple, 4 quad), from a dual mailbox post for two households sharing an approach, up to a triple mailbox post or a quad configuration for larger developments.

Every unit in a set uses matching hardware, finish, and locking mechanism, so a new HOA mailbox installation looks intentional rather than assembled piece by piece. Browse our multi-unit combos, and if you’re specifying for more than a handful of units, request a bulk quote or call us directly at 866-717-4943. We’ll work the per-unit cost with you rather than through the cart.

USPS Placement Rules for Curbside Mailboxes

USPS sets four placement requirements for curbside delivery:

• Mounting height of 41 to 45 inches from the road surface to the bottom of the mailbox
• Setback of 6 to 8 inches from the curb or road edge
• A clear approach for the carrier’s vehicle, with no obstruction from parked cars or landscaping
• A visible house number on or near the box

One distinction gets missed often: USPS approves mailboxes, not mailbox posts, per section 6.2 of USPS’s engineering standard for curbside boxes. The Postal Service does not regulate or approve the post itself or its mounting beyond the four placement rules above. There’s no such thing as a usps approved mailbox post, only a properly installed one that keeps an approved mailbox at the correct height. See USPS’s own placement guidance for the full federal requirements.

A curbside mailbox with post that meets these figures satisfies USPS on its own. For a complete breakdown of federal and local requirements, see our mailbox regulations guide, our post mount FAQ, or our step-by-step install guide.
