Overlay Area Codes

This area code shares its geographic footprint with 2 overlay codes, so the same cities are served by multiple 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 678 (Atlanta), area code 943 (Atlanta).

With prefix utilization already at 98.3%, numbering resources here are under sustained pressure — context that explains why overlays were introduced.

In service since: 26-Feb-2010
