Florence Mailboxes

Florence Corporation is one of the nation's top commercial mailbox providers, offering a wide range of USPS-approved options for any business or property need. The brand began in 1934 and has since revolutionized centralized mail distribution within USPS security standards. Whether you own an apartment complex, a brand new construction project, large corporate development, or any other commercial property, Florence Corporation likely has products designed for your needs.


Florence crafts all commercial mailboxes according to the highest standards, offering a five-year limited warranty to ensure that you're happy with the results. The U.S.-based manufacturing brand cares about its environmental impact and relies on a recycling and reusing program for all suitable materials, including aluminum, metal, powdered paint, steel, and more.

At Mailbox Depot USA, we offer a wide range of Florence products and accessories for any of your mail system needs.

Florence Commercial Mailboxes

Florence primarily produces commercial mailboxes that adhere to USPS security, durability, design, and access specifications. The brand's top commercial mailboxes include 4C cluster systems, horizontal mailboxes, and vertical styles.

Pedestal Cluster Box Units

Florence provides a variety of cluster box units (CBUs) available on pedestal design systems for outdoor use cases. You can choose from six different unit sizes and four color options with various accents for full customization. The brand also provides high-security CBU options for limited access and reduced theft risks.


Depending on your use case, you may need prior approval from USPS to use pedestal units. We recommend contacting your carrier before adding these products to your cart.

4C Recessed Cluster Mailboxes

You may also prefer indoor CBU installation, depending on your property type. Florence offers recessed 4C cluster mailboxes that meet the most up-to-date USPS requirements, meaning you may use this system for brand-new construction projects or major renovations. You can choose between front- and rear-loading options with a number of sizes and design choices.

4B Horizontal Mailboxes

4B horizontal mailboxes do not meet the most current USPS standards, which means you may not use them for new construction or major renovation projects. You can use this mail system for replacement installation.


Florence offers a wide selection of horizontal mail systems ranging in size, functionality, accessories, and style. We recommend confirming your requirements with USPS before adding a horizontal mail system to your cart.

Vertical Mailboxes

Like horizontal mail systems, vertical units only meet 4B standards, which means you may only use them to replace an existing system. Florence offers various vertical sizes and configuration options, depending on your needs.


We recommend speaking with your local USPS to determine whether or not this mail system will work for your property. Once you get pre-approval from USPS, you may add the mail system and any accessories to your cart.
