Orlando, FL utilizes an area code overlay in which area codes 321 and 407 serve the same geographic area. Ten digit dialing (area code + seven digit number) is necessary because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code. The area code overlay which is in use today was established in 1999 and unlike some area code overlays area code 321 only overlays a portion of area code 407
In addition to Orlando, FL area codes 321 and 407 serve an area of east-central Florida that includes Orlando and the larger cities and communities of Altamonte Springs, Cape Canaveral, Casselberry, Cocoa Beach, Kissimmee, Longwood, Oak Ridge, Ocoee, Oviedo, Pine Hills, Sanford, St. Cloud, University Park, Wekiva Springs, Winter Park and Winter Springs in addition to many smaller communities.
