813 Area Code: Tampa, Florida

The 813 code is the long-running area code for the Tampa Bay region's eastern shore, with Tampa as the primary city. Tampa sits at the head of the bay where the Hillsborough River reaches saltwater, organized around a working port, a downtown that has expanded substantially through the past decade, and a metropolitan area that takes in Brandon, Riverview, and the surrounding cities of Hillsborough County. The 813 designation has carried the region's numbers since long before Florida's later round of overlays.

Records the directory has compiled for 813 numbers frequently include Cape Coral, Deltona, Fort Lauderdale, Gainesville, and other Florida cities. None of those are inside the 813 footprint. The pattern reflects standard public-record dynamics — porting and address linkages — across the state. The directory currently documents 680 distinct prefixes within 813 in detail, a working subset of the prefix population the code actually carries.

Tampa's median household income comes in below the US figure but not severely so, with the city's diversified economy — finance, healthcare, port-related logistics, and tourism — shaping a labor market that pulls in workers across a wide range of wage levels. 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 population places Tampa among the larger Florida cities, the anchor of a metropolitan area that extends across the bay.
