California (626) area code webcast notice

The California Public Utilities Commission (CPUC) will begin the process to introduce a new area code to the area now served by the 626 area code, as the 626 area code is expected to be depleted of phone numbers in the fourth quarter of 2027. Pending approval by the CPUC, the new area code will be introduced on top of the 626 area code using the overlay method.

The CPUC will have a recorded webcast to inform the public about the overlay. Topics to be discussed in the recorded webcast include: (1) History of the 626 area code; (2) Area code relief process; (3) Overlay relief method; (4) Effects of the pending overlay; and (5) Implementation periods. The recorded webcast will be available at https://www.cpuc.ca.gov/AreaCodes/ beginning May 13, 2025. Comments about the 626 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 320 W. 4th Street, Suite 500, Los Angeles, CA 90013 by June 13, 2025. A copy of the webcast presentation slides may be requested by contacting the CPUC Public Advisor’s Office by email at public.advisor@cpuc.ca.gov, or by phone at (866) 849-8390.
