916-Telephone#/Overlay with New Area Code

Updated November 28, 2017
Cell Phone
To ensure a continuing supply of telephone numbers, the new (279) area code will be added to the area served by (916). This is known as an area code overlay. An overlay is the addition of another area code (279) to the same geographic region as an existing area code (916). An overlay does not require customers to change their existing area code but does require customers to include the area code for all local calls, including calls within the same area code. 

Everyone with a 916 area code is affected. The (916) area code covers the Sacramento area including the cities of Sacramento and West Sacramento, as well as Citrus Heights, Elk Grove, Folsom, Isleton, Lincoln, Loomis, Rancho Cordova, Rocklin and Roseville. The new (279) area code will serve the same geographic area currently served by the existing (916) area code. To complete calls from a landline phone, the new dialing procedure requires anyone with a (916) area code to dial 1 + area code + telephone number. 

January 29, 2018: News Broadcast to Citywide is scheduled.

February 10, 2018: Everyone must use the new dialing procedures, as described above for all calls. After this date, if you do not use the new dialing procedures, your calls will not be completed and a recording will instruct you to hang up and dial again.

March 10, 2018: New telephone lines or services may be given numbers from the new (279) area code.

In addition to changing your dialing procedures, all services, automatic dialing equipment, or other types of equipment that are programmed to dial a 7-digit number will need to be reprogrammed to use the new dialing procedures. Some examples are life safety systems and medical monitoring devices, PBXs, fax machines, Internet dial-up numbers, alarm security systems and gates, speed dialers, call forwarding settings, voicemail services, etc. 
The overlay will primarily affect the greater Sacramento area, which includes parts of El Dorado, Solano, Sutter, Yolo, Placer, and Sacramento Counties.
This change may impact our future ordered City cell phones with the new area code. We would like the City to remain aware of these changes and potential impacts moving forward.

As for what will remain the same, your current telephone number, including current area code, will not change. The price of a call, coverage area, or other rates and services will not change due to the overlay. What is a local call now will remain a local call regardless of the number of digits dialed. You can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 and 811.
