Basic info Basic info

From December 23rd, 2021 residents of California living within Numbering Plan Area 909 borders are able to get new telephone numbers in a second area code 840, which is an overlay code covering the same geographic area. One of the downsides of having two or more area codes assigned for the same location is the technical necessity to dial more digits. In the case of the new overlay complex 909/840, 1+10 digit dialing is required.
