Area Code 704 is one the original area codes assigned in 1947. The code belongs to the state of North Carolina (NC) and serves Metropolitan Charlotte - Piedmont region. NC is South Atlantic State and areas covered by the state follow Eastern Time Zone for standard time.
The code 704 was overlaid by area code 980 in 2001 because of the ever-increasing demands for telephone lines. It was time when the available phone numbers for area 704 had almost been diminished. Overlaid area code 980 was created with the purpose of serving customers for wireless phones and pagers. The 704 code was suggested to cover entire state of North Carolina (NC). However population spurts and greater than ever demands for telephone lines left no option except to divide the area into smaller parts. Therefore code 704 split to form area code 919 which was further split into new area code ? code 828 in 1995.
As the code 704 is overlaid by code 980, it is mandatory to use a ten digit calling while even making local calls. Area Code occupying same geographic boundary as the existing area code is actually an overlay. Existing numbers are not changed and retain same code ? however new codes are assigned to new numbers. Codes are used to differentiate particular areas.
The 704 code is surrounded from four sides by area codes:
