About the 728 Area Code

Florida's 728 area code is among the newer overlays planned for the northeast region of the state, with Jacksonville as the directory's anchor city. Jacksonville sits along the lower St. Johns River, across a sequence of bridges that lift up over the river's wide bend toward the Atlantic, and the city's geographic footprint is among the largest of any incorporated city in the country. The 728 designation, part of the North American Numbering Plan, is in the early phases of being filled with active number assignments.

In records the directory has compiled for 728 numbers, other Florida cities — Cape Coral, Deltona, Fort Lauderdale, Gainesville, and others — appear regularly. None of those are inside the 728 footprint. Their appearance reflects standard public-record dynamics — porting, prior registration, and address linkages — that move records across Florida without filtering on area-code geography. The directory currently documents 1 distinct prefix within 728 in detail, an early-stage subset that represents the start of our coverage rather than a comprehensive count.

Jacksonville's median household income runs below the US figure but not dramatically so, with home values coming in below the national median — an unusual reading for a coastal city. The city's median age sits in the mid-thirties (a few years under the US figure), and population places Jacksonville among the larger cities in Florida by total headcount, particularly because the city's consolidated boundaries take in much of the surrounding Duval County. The working economy reflects a substantial port, naval installations, and a long-standing role as the financial center of northeast Florida.
