Published: Verified against NANPA and FCC records
Overlay Area Code
This area code shares its geographic footprint with an overlay code, so the same cities are served by two area codes. Because overlays leave existing numbers untouched, this region's relief planning favors adding codes over redrawing boundaries.
The codes serving this same region: area code 980 (Charlotte).
With prefix utilization already at 97.8%, numbering resources here are under sustained pressure — context that explains why overlays were introduced.
In service since: 01-Jan-1947
Area Code Splits
One area code has been carved out of this code's original territory through a geographic split. Each split was a relief action: as demand grew, part of the region was reassigned to a new code rather than overlaying the whole territory.
Split into: area code 828 (Asheville).
