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 728 (West Palm Beach).

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

In service since: 13-May-1996

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 772 (Port St. Lucie).
