About Area Code 321
Area code 321 is a North American Numbering Plan (NANP) area code that has been in service since 1999. It is administered by NANPA on behalf of the FCC and serves the Florida region anchored on Orlando.
321 is currently a single-coverage geographic area code with no overlays. This means a 7-digit number in this area code is unique within its rate centers, though best-practice is always to dial the full 10-digit number when contacting a 321 line.
Mobile numbers in 321 are portable: a person who moved away from Orlando may still carry a 321 mobile number on their device. If you receive an unexpected call from a 321 number, run it through the reverse lookup tool above for the most accurate, free identification.
