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 924 (Rochester).

With prefix utilization already at 95.4%, numbering resources here are under sustained pressure — context that explains why overlays were introduced.

In service since: 01-Jan-1954
