Another telephone area code is coming to the Philadelphia region.

Available phone numbers with the current 215 and 267 area codes will soon be used up, so a new code will be needed for future numbers issued in the region.

The Pennsylvania Public Utility Commission this week approved a plan to implement an overlay for the area now covered by the 215 and 267 codes.

The new code appears on track to be the same one that was nearly assigned to the area in the early 2000s: 445.

Numbers available using 215 or 267 are expected to be exhausted sometime in 2018, according to the commission. The overlay plan will let additional phone numbers then be assigned out of the new area code.
