What Postal Products Unlimited Inc. does

Postal Products Unlimited, Inc. is a Milwaukee, Wisconsin-based manufacturer and direct-to-customer distributor of USPS-approved mailboxes, mail center equipment, and storage lockers, founded in 1987 and operating under the Mailproducts.com and "Mailboxes & Postal Specialties" brands. Its product portfolio centers on heavy-gauge aluminum commercial mailboxes (F-Spec Cluster Box Units, STD-4C Horizontal Mailboxes in both standard and high-security variants, 4B+ Horizontal Mailboxes, vertical mailboxes, parcel lockers, collection/drop boxes, and P.O. boxes) complemented by a residential line (decorative curbside series such as 1812, 1092, Classic Colonial, Estate, Vintage Aluminum, locking units, and address plaques), a broad mail-center supplies catalog (furniture, carts, trucks, totes, trays, racks, matting, mailing/packaging supplies), and a storage locker line including the Guardian Whisper Series. Technical differentiators include USPS STD-4C compliance (mandatory for new construction and major renovations since October 2006), concealed-hinge and anti-fish-comb security architecture, corrosion-resistant powder-coat finishes, stainless-steel hardware, and an ISO 9001:2015-certified quality management system.

The company operates a sales-led, direct-distribution model through its mailproducts.com e-commerce storefront supplemented by phone (800-229-4500) and live-chat inside sales, with sales representatives providing custom 3-part specifications and CAD drawings to architects, engineers, general contractors, property managers, dealers, and end customers across North America. Revenue is generated predominantly through one-time unit sales of physical mailbox and locker products, with bulk-quote pricing available for large commercial projects and multi-year contracts referenced for larger commercial engagements; pricing varies by door count and configuration, with standard 4C units ranging from roughly $1,800 to $2,900 and parcel-locker-equipped configurations priced higher. The customer base spans enterprise end-users (Amazon, Boeing, Disney, FedEx, AT&T, Microsoft, GM, GE, Marriott, Walgreens, Home Depot, Lowe's, Grainger, Chevron, Edward Jones, Bloomberg, Union Pacific, Saks Fifth Avenue, 7-Eleven, Ace Hardware), large construction firms (Bechtel, Fluor, Turner Construction), national homebuilders (D.R. Horton, Lennar, Toll Brothers), educational institutions (Brown University, Ohio State), healthcare (Children's Hospital), and direct federal supply to the United States Postal Service, alongside a dealer/distributor channel and individual homeowners purchasing through the website.
