Area code 305

Area code 305 serves Florida, including Miami, Keys and North Dade (Eastern time). It has been in service since January 1, 1947 and shares its area with 645 and 786.

Numbers starting with 305 drew 1,949 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 757 complaints to the FCC since November 2023. The number on your screen can be faked, so a 305 number proves nothing about where a call came from.

Phone companies holding 305 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 43% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
