Who Own's Your Mailbox?
Our Expert Knowledge
A common question we get at CJ Flag & Son is, “Are mailboxes city property?” The answer is no—but they aren’t fully owned by the homeowner, either.
Once you purchase and install a mailbox that meets USPS regulations, it becomes federal property, allowing you to send and receive mail through the U.S. Postal Service.
If you’re considering a new mailbox, contact CJ Flag & Son today! We provide durable, high-quality residential mailboxes in a range of styles and colors, along with custom address plaques to complement your home’s architecture. Serving Lindenhurst, NY and surrounding areas, we offer expert guidance on mailbox sizing, pricing, and installation.
