The End of an Era: 707 Area Code Will Stop Being Issued by December 2023

The following letter was sent to the Mendocino County Board of Supervisors by the California Public Utilities Commission:

This letter is to inform you that the California Public Utilities Commission (CPUC) will begin the process to introduce a new area code to the area now served by the 707 area code. The 707 area code is expected to be depleted of available prefixes by December 2023. Pursuant to Federal Communications Commission policy and CPUC rules, the CPUC must adopt an area code relief plan to provide additional numbering resources. Pending approval by the CPUC, a new area code will be introduced on top of the 707 area code using the overlay method. The new area code will provide additional prefixes and new telephone numbers for customers in the 707 area.

When the CPUC begins area code relief planning in the area served by an existing area code, the perspectives of local government officials and the community are very important. The CPUC has made available a recorded webcast to inform local jurisdictions and the public about the new area code addition. We invite you and your constituents to view the recorded webcast and to provide comments. The recorded webcast will be available at https://www.cpuc.ca.gov/AreaCodes/ beginning August 1, 2021. Comments about the 707 area code overlay may be submitted to the CPUC Public Advisor’s Office by e-mail at public.advisor@cpuc.ca.gov, or by postal mail to 505 Van Ness Ave., San Francisco, CA 94102 by October 1, 2021.

Enclosed is a notice with information on the new area code and the recorded webcast, along with a map of the area now served by the 707 area code. Please share this information with your constituents and encourage them to view the recorded webcast to ensure they are aware of the impending new area code overlay.

Sincerely,
Jonathan Lakritz, Consumer Programs Manager Communications Division
