What is the 305 Area Code?

Area code 305 serves southern Florida, primarily Miami-Dade County and parts of Monroe County. It is one of the original North American area codes created in 1947. Today, it shares service with overlay codes 786 and 645. Cities in this area include Miami, Hialeah, North Miami Beach, Homestead, Coral Gables, and Key Biscayne.

Initially, 305 covered the entire state of Florida. Over time, as population and phone use expanded, the area code was divided. It now focuses on the southeastern region of the state. The growing demand led to the introduction of 786 in 1998 and the more recent 645 overlay in 2023.

This area code also stretches to northern Monroe County and parts of the Florida Keys, such as Key Largo, Islamorada, Marathon, and Layton. The region is widely known for tourism, financial hubs, and global connections.

Due to increasing demand, the Florida Public Service Commission approved area code 645 to supplement 305 and 786 starting in August 2023. This ensures continued availability for new residents and businesses.
