About Area Code 305
Area code 305 is a North American Numbering Plan (NANP) area code that has been in service since 1947. It is administered by NANPA on behalf of the FCC and serves the Florida region anchored on Miami.
305 now shares its territory with an overlay code (786). 10-digit dialling is required for local calls within this region because the same 7-digit number can be assigned under either code.
Mobile numbers in 305 are portable: a person who moved away from Miami may still carry a 305 mobile number on their device. If you receive an unexpected call from a 305 number, run it through the reverse lookup tool above for the most accurate, free identification.
If you live or do business in Florida, you may also interact with neighbouring or overlay codes (786). See the related codes section below to explore the rest of Florida.
