Our Story

Established in 1998, U.S. Post Company is a leading manufacturer of quality mailboxes, mailbox posts, street signs, and lighting. U.S. Post prides itself on its manufacturing quality along with excellent customer service. Each product, whether cedar, aluminum or cast iron, is constructed with care and built to last. All products are DOT certified. Each is installed based on local postmaster standards in keeping with local development requirements. 

U.S. Post has a factory direct pricing structure that allows us to offer the highest quality mailboxes at the lowest possible pricing. You will not find comparable products at a lower cost anywhere, not on the Internet, not in stores. 

Our service and installation is second to none. In new developments, U.S. Post works with local Postmasters to determine proper mailbox placement. Most mailboxes that are not properly installed will lean or sag with one or two years. Not a U.S. Post installed mailbox. 

No customer is too small or too large. Whether you are a home owner or a subdivision builder, U.S. Post will be glad to work with you to enhance the look and value of your property with our specialty product line. Contact us today to begin enhancing the image and curb appeal of your property.

New Installation:

U.S. Post Company will install any new mailbox system for your home as well as remove and haul-away the current mailbox. All of our installations are done with cement and follow the United States Postal Service guidelines which request mailbox systems to be installed between 41" to 45" above ground level, 6" to 8" back from the curb and approximately 24” deep. U.S. Post Company will contact the local postmaster for any unforeseen permissions needed. Builders will need to supply site map in advance. Please call our office for more details.

Custom Designs:

Looking for something “one of a kind”? U.S. Post Company can custom design any style mailbox system. There are endless options available. Please contact our office to get started on your custom design today!

Repairs / Replacements/Resets:

U.S. Post Company can replace or repair most parts. Some damage is more extreme so pictures are often requested to give a more specific idea of how we can help. Parts that U.S. Post Company does not manufacture, are not stock items and will need to be ordered with a short lead time. If just your mailbox post needs to be secured into the ground, U.S. Post Company offers Post Resets with cement. Please call our office for more details on repairs, replacements and post resets.


If your local USPS is requiring any adjustment in the location of your current mailbox system, U.S. Post Company can help. We will confirm the specifics from the local postmaster and get your mailbox location where it needs to be. U.S. Post Company also offers relocation to street signs as well.

Cluster Box Lock Replacements:
