The area code 305 is located in Miami, Florida.
Area code 305 serves the far southeast corner of Florida, anchoring Miami-Dade County and stretching down through the Florida Keys to Key West. It was established in 1947 as one of the original area codes under the North American Numbering Plan and originally covered the entire state of Florida before later splits. Today, 305 is known worldwide as the Miami area code, tied to the city’s culture, beaches, and international vibe. The region uses the Eastern Time Zone and includes an overlay with area code 786, which means 10-digit dialing is required.
