History of Area Code 786
Area code 786 was created in 1998. It was introduced as an overlay for area code 305 in Miami-Dade County after strong growth in population, cell phones, fax lines, and new business lines increased demand for phone numbers.
Area code 786 did not replace 305. It was added on top of 305, which meant both area codes served the same geographic area. In 2023, area code 645 was added as another overlay for the same region because the supply of available numbers kept shrinking.
