Why Imperial? A Brand Overview

History of Excellence

A trusted industry leader, Imperial Mailboxes has been manufacturing the finest cast aluminum mailboxes, street signs, and lamp posts since 1989. Imperial products have enhanced the most prominent residential communities and planned developments in America, beautifying landscapes and improving property values in grand style. Their extensive line of beautiful and dependable products meet the varied needs of discerning homeowners, developers and project architects alike, allowing one coordinated design to be chosen for all exterior accents.

Superior Craftsmanship

Imperial products are built to last and look great for years. Posts, Decorative Mailboxes, and components are expertly die cast using high-grade solid aluminum, providing strength, durability, and unsurpassed quality. The aluminum is then powder coated at high temperatures with industrial strength enamel paint and assembled to the highest standards with stainless steel hardware.

Large Variety of Preconfigured and Custom Mailbox Systems

Choose from an assortment of pre-configured mailbox systems, mailboxes, posts, address plaques, and accessories to customize your look to your exact specifications. Most pieces are interchangeable for full customization of your order. If you have any questions or concerns before placing an order, one of our Customer Care Representatives will be happy to assist you.

Manufacturer's Warranty

Imperial provides peace of mind with a limited one year warranty covering defects in construction and assembly. The warranty is valid to the original purchaser and does not cover improper installation, alterations, vandalism, etc. Imperial Mailbox Systems must be contacted within one year of the original delivery date. Please see the full Manufacturer's warranty for more details.

Construction & Materials

Cast Aluminum Construction

Each Imperial product is constructed of the highest-quality, solid cast aluminum and assembled using rust-free and worry-free stainless steel hardware. Aluminum is a strong, lightweight metal that is resistant to rust, corrosion, and environmental damage, making it the optimal choice for outdoor products. The process of sand-casting each mold helps to maintain a superior level of quality control.

Powder-Coated Finish

Following casting, each piece is powder coated at a high temperature using an industrial strength enamel paint to provide a smooth, beautiful, and extremely durable finish that will stand the test of time. Products are offered in a variety of classic colors, so be sure to browse our color options.

Stainless Steel Hardware

Stainless steel hardware and locking mechanisms round out the tough construction of the Imperial product line. Stainless steel offers the same rust and corrosion resistance similar to aluminum while contributing added strength where it is needed most. This yields a finished product that is durable, secure and built to last.

Imperial Mailbox Configuration Options

Imperial Mailbox Systems offers the widest variety of configuration options on the mailbox market today, ensuring that your custom designed package perfectly suits your needs as well as your style. From the mailbox and post to the powder-coated finish, address number plate and grand finial, Imperial allows for a multitude of brilliant mailbox configurations. If you prefer a pre-designed package that takes the guesswork out of ordering and arrives ready to assemble, we have many pre-configured packages available that will make your selection simple and save you time.

Every number or letter in the package SKU identifies the part included with your Imperial Mailbox package. Choose from one of our attractive pre-designed packages or build your own with Imperial's extensive line of product offerings. Either way, we are here to help you find the perfect design to enhance your personal home or planned development project.

Overview of Imperial Components

To design a custom package, simply choose a mailbox post, address number plate, and a standard or estate-sized mailbox. An easily-mounted newspaper holder is a valuable option to keep your daily editions safe and dry. Beyond your mailbox system, Imperial offers street signs, street lamps, and address plaques to perfectly compliment your chosen package.

Selecting Your Imperial Systems Post

Imperial posts boast superior style and function, containing a sturdy base, decorative pole, and grand finial. They are engineered using extruded aluminum for durability, offering a strong foundation for your mailbox. Each post is expertly crafted using the same cast-aluminum and powder-coating processes as the entire Imperial line.

Imperial Systems Posts, compatible with Imperial's Decorative Mailboxes 0-9, are as follows:

Selecting Your Mailbox

Imperial mailboxes are engineered to last for years. The Imperial design is offered in the standard USPS size (19 in. L x 7.75 in. W x 9 in. H), as well as the larger Estate Size mailbox for rural areas (21.75 in. L x 10 in. W x 12 in. H). The Estate Mailbox is 45% larger than a standard box, allowing for larger parcels and multiple days' worth of mail. Not all post options are available when opting for the larger Estate size.

Box 0 - Plain

Box 1 - Fleur de Lis with framed panel

Box 4 - Eagle

Box 6 - Fleur de Lis

Box 7 - Horse

Estate Size Mailboxes are available in Styles 0, 1, 4 and 6.

Mailbox Colors

Once you've chosen your mailbox and post, it's time to choose a color finish. As with all Imperial products, they are powder-coated with industrial strength enamel to withstand even the harshest weather conditions, keeping your mailbox's color vibrant for years to come.

Choose from the following powder-coated finishes:

Address Plates

Plate 1
Accepts 2 in. brass numbers
Compatible with standard boxes

Plate 2
Accepts 2 in. brass numbers
Compatible with standard boxes

Plate 3
Accepts 2 in. brass numbers
Compatible with estate boxes

Plate 8

As with other aspects of your design, you can choose from several variations on the Imperial address plate. Choose carefully based on compatibility with your selected mailbox or post. Plates 1 and 2 fit atop any standard-sized mailbox. Plate 3 accommodates estate-sized mailboxes.

Brass Address Numbers

Two-inch Brass Address Numbers are available for Address Plates 1, 2 and 8. If purchased with a mailbox and number plate, the manufacturer will install the numbers onto the plate before shipment. Alternatively, you can order adhesive numbers to apply yourself.*

Three-inch Brass Address Numbers are available for Address Plate 3. If purchased with a mailbox and number plate, the manufacturer will install the numbers onto the plate before shipment. Alternatively, you can order adhesive numbers to apply yourself.*

*Don't forget to order each number in a quantity of 2 if you want address numbers for both sides of the Address Plate.

Newspaper Holders

The Standard Size Newspaper Holder (6 in. W x 6 in. H x 15 in. L) or Estate Size Newspaper Holder (8 in. W x 7 in. H x 19 in. L) ensure that your daily editions stay safe, dry and conveniently located. Both holders easily and securely mount below your standard or Estate size Imperial mailbox with stainless steel hardware (included). Like all Imperial products, they are expertly crafted of sand cast solid aluminum and powder coated to match your chosen mailbox finish. Some pre-configured mailbox packages include a newspaper holder, such as the Fleur de Lis Residential System, Estate Fleur de Lis Residential System and Century Residential System. Alternatively, newspaper holders can be purchased separately to correspond with your custom designed package.

Coordinating Street Signs

Eight-foot street sign posts can be configured to perfectly coordinate with your mailbox system. A stunning accompaniment for developers and estate owners who would like to maintain a cohesive aesthetic, you may choose street signs, street lamps and address plaques to match any Imperial mailbox and post system. All signposts configurations are DOT approved.

Browsing the Lamps, Signs, & Plaques section of the Imperial brand page can greatly assist you in creating your customized home or community design.

Coordinating Lamp Posts

A perfectly coordinated eight-foot lamp post can be selected to illuminate your personal mailbox system or your entire community project. Studies show that a well-lit mailbox is less likely to be burglarized than one without any lighting. Browse Imperial's stunning collection of lighting options from our Lamps, Signs & Plaques Page.

Remember, a licensed electrician is recommended for all lighting installation.

Twin and Multi-Unit Mailbox Systems

Imperial offers both Plate Extensions (for existing mailbox posts) and Twin and Multi-Unit Mailbox Systems to configure a delivery system for one location servicing multiple addresses. A gorgeous solution to the sometimes mundane multi-mailbox systems, Imperial Multi-Unit Systems will add style, sophistication and superior function to your multi-dwelling residential projects.

Plate Extensions


Plate extensions bolt to your existing Imperial Mailbox Post, allowing the mounting of a mailbox or mailboxes on two opposite sides of the post. Choose from Twin, Triple or Quad Plate Extensions in your chosen finish for your multi-dwelling needs.

Twin Mailbox Systems

For convenience and ease of selection, we offer an extensive selection of pre-configured Twin Mailbox Systems to meet your multi-dwelling needs with optimal style and function. Complete with Address Plates on both mailboxes and newspaper holders for each tenant, the Twin systems offer superior quality, ease of use, and aesthetic appeal. (Note that Twin systems can accommodate a Newspaper Holder; Multi-Unit systems cannot.)


Multi-Unit Mailbox Systems


Imperial's Multi-Unit Mailbox Systems house a support plate that accommodates the mounting of at least three (3) and up to six (6) mailboxes between two chosen posts. (Please be aware that a newspaper holder cannot be attached when utilizing the multi-box configuration.) You can view our selection of Multi-Unit Mailbox configurations here.

Replacement Parts

Imperial intentionally engineered a completely bolt up system; therefore, should your Imperial Mailbox or components thereof suffer any damage, you will not have to buy an entirely new system and only the individual part need be replaced.

Assembly and Installation

Would you like to know what to expect from the assembly and installation process of your new Imperial Mailbox System? We have you covered. You can review assembly and installation instructions (link opens a .PDF) for all Imperial Products, or read our brief overview below.


Completely assemble mailbox unit. Dig a hole approximately 16 inches deep using a shovel or post-hole digger and install mailbox post in concrete. Some temporary support may be necessary while concrete sets.

Installation steps:

  1. Attach the number plate to the top of the mailbox.
    1. If you have a newspaper holder, use 6-inch straps (not included) to keep your newspaper holder in place during assembly.
    2. The back of the mailbox and the back of the newspaper holder should be flush with each other.
  2. Attach scroll support (A) to the bottom of the mailbox.
  3. Place top two bolts in post and mailbox. Do not tighten.
  4. Lift front of the mailbox to place scroll support dowel pin into the post.
  5. Attach lower bolts and tighten all.
  6. Place assembled post into the hole, align the box with the curb line, and add concrete.
  7. If necessary, drive a stake into the ground 3 or 4 feet behind the post. Tie a string from the stake to the top of the mailbox post to keep it plumb while the concrete sets.

Regarding a Product's Shipping Estimate

Understanding Lead Times

The lead times listed on this product page represent the best-case scenario for shipping estimates. While we may show that a product "usually ships" within a given period, this period should not be confused with a delivery estimate. Rather, we expect the product to ship from the manufacturer's warehouse within this time-frame.

What does this mean for you? Once you place an order on our site, we begin processing the order with the manufacturer. The processing lead time we list on the product page is the most current estimate from the manufacturer regarding the product.

Below, we answer the top three FAQs our customers have regarding delivery estimates.


How long will it take to receive my commercial mailbox?

When you order a commercial or cluster mailbox, we process the order with the manufacturer within 1 business day. Once processed, the order usually ships in the time-frame listed on the product page. Since Cluster Mailboxes are large items, they ship via freight carriers. This means that the transit times for these will usually be 5 to 7 business days.

A few things to note about purchasing a cluster mailbox or similar large, commercial-grade product:

  • The freight carrier will call the number you list on the shipping address a day before delivery to schedule a delivery appointment with you.
  • The manufacturer ships using their chosen freight carrier depending on the products ordered and the delivery location.
  • The majority of online retailers who sell commercial mailboxes (CBUs, etc.) ship directly from the manufacturers, just as we do.
  • If you purchase a commercial mailbox from us and decide to cancel because a competitor lists a "faster" lead time on their site, you may be delaying the time it will take to receive your mailboxes. Why? Because you are placing a new order to be sent to the same manufacturer for processing.
  • If you choose professional mailbox installation with your commercial mailbox purchase, please note that same-day installation is not available. Installation will be scheduled after the delivery of your mailbox. In most cases, installation is completed within one week following delivery.

What if I order multiple products from different brands?

If you ordered multiple products, it is possible that they are made by different manufacturers. If this is the case, your products will ship to you separately from each manufacturer.

For example, if you purchase a Mayne Post with a Whitehall Mailbox, your post will ship from Mayne's warehouse in about 3 business days, but your mailbox will ship separately from Whitehall in about 2 to 3 weeks if customized with address numbers.

How can I estimate my shipment's transit time?

Depending on the carrier and your location, transit times will vary. Delivery estimates are best projected using your carrier tracking number. Once your order ships, we'll send you a shipping confirmation email that includes your carrier (FedEx, UPS, YRC, etc.) and tracking number.

Note: If you place an order with us and do not receive an Order Confirmation email, check your spam inbox. If you still do not see an Order Confirmation email in your inbox, contact us right away at (866) 707-0008 . We will provide you with your Order Number and any other details you need.

What is the CBU Price Match Guarantee?

Price Match

It's pretty simple. If you find this model* cluster mailbox on another online retail site for a lower price, including any shipping and taxes, then we will match that competitor's price.

Before we can match a competitor's price, please note:

  • We will need the exact URL of the product page in question. A screenshot of the competitor website will not suffice.
  • Some competitors hide their freight charges until you enter the checkout, so please keep this in mind.
  • If you are ordering multiple units, check our Volume Discount Pricing table (to the right of our sale price) to see if we're the better price for the quantity you need.

* By "model", we mean a CBU that has the same number of tenant doors and the same manufacturer specifications.
