305 Area Code in Florida, United States

Area code 305 is one of the original area codes established in 1947 and currently serves Miami-Dade County and parts of the Florida Keys. Originally, it covered the entire state of Florida, but has since been split multiple times due to population growth. Today, 305 is synonymous with Miami’s international culture, nightlife, and prominence in finance, tourism, and entertainment. In 1998, area code 786 was overlaid on 305 to accommodate further growth, and ten-digit dialing became mandatory. Despite the overlay, 305 remains a cultural icon, frequently referenced in music, fashion, and branding—especially in South Florida hip-hop and Latin communities. The code is a symbol of local pride, often seen on apparel, license plates, and social media.
