Area code 786 is an overlay for 305, serving Miami and its surrounding areas in Miami-Dade County and parts of the Florida Keys. Introduced in 1998, 786 was added to address number exhaustion caused by Miami’s explosive growth in population, tourism, and telecommunications. Although newer, 786 is now common on mobile numbers and business lines throughout South Florida. The number itself has become culturally significant, particularly in local music and branding, alongside the iconic 305. Ten-digit dialing is mandatory across the region. 786 has cemented its place in South Florida's identity, representing modern growth, diversity, and international connectivity in the Miami metro area.
