The 645 code is one of Florida's newest overlays, layered into the Tampa Bay region alongside the long-running codes that have served the area for decades. Tampa anchors the directory's records for 645. The city sits at the head of Tampa Bay, where the Hillsborough River reaches saltwater, and its working economy is shaped by a substantial port, a long-standing financial-services sector, and a steady flow of tourism along the coast and the surrounding bay. The 645 designation, part of the North American Numbering Plan, is in the early phase of being filled with active assignments.
In records the directory has compiled for 645 numbers, other Florida cities — Cape Coral, Deltona, Fort Lauderdale, Gainesville, and others — appear regularly. None of those are inside the 645 footprint. The recurrence reflects standard public-record dynamics across Florida, with porting and address linkages routinely surfacing other-city names alongside 645 records. The directory currently documents 1 prefix within 645 in detail, an early-stage subset that should be read as the start of working coverage rather than the prefix total.
Tampa's median household income comes in below the US figure but not severely so. Home values run above the national median, in line with broader Florida pricing pressure, the city's median age sits in the mid-thirties (a few years under the US reading), and the population places Tampa among the larger Florida cities — substantial enough to anchor a metropolitan area that extends across both sides of Tampa Bay and pulls steadily on populations across the central Gulf Coast.
