Did you know?
• Serving on the US Postal Service (USPS)
Apartment Mailbox Consensus Committee,
Florence was part of the leadership team
who worked to develop the standard 4C
regulation and specification to meet the
changing customer mail delivery needs.
• All STD-4C mailboxes must pass rigorous
inspection and testing by the USPS prior
to being awarded Approval status; this
includes passing an unsuccessful break-in
over a designated period of time.
• Deep in the American Heartland, Florence
operates a vertically integrated state-
of-the-art facility in Manhattan, KS and
is proud to say our mailbox and storage
products are Built in the USA!
• In recent years, Florence has used an
average 9.8 million pounds of aluminum
in our handcrafted centralized delivery
mailboxes - that is enough to circle the
globe nearly 400 times!
• Florence was the very first manufacturer
in our industry to be ISO certified for our
manufacturing & management processes
and is the only one in our industry to also
be ISO certified for our environmental
practices as well.
• Over the last 10 years, the USPS has
awarded Florence two different sole-source
equipment contracts and five different
supplier awards (Supplier Innovation,
Supplier Excellence, and Quality Supplier).
• While Florence mailbox products may be
best known across North America, they are
installed and used world-wide.
