909 Area Code

The California Public Utilities Commission (CPUC) will begin the process to introduce a new area code to the area now served by the 909 area code, as the 909 is expected to use up its available prefixes by March 2019. The telecommunications service providers have proposed to introduce the new area code through the overlay method. Adding a new area code to the area now served by the 909 area code will provide additional prefixes and new telephone numbers for the 909 customers. The proposed overlay, pending CPUC approval, will allow all customers to keep their current phone numbers, including their area code. To avoid service disruption, the new area code will be added to the 909 area code by September 2018, six months before the depletion of prefixes. In September 2018, customers requesting new phone numbers in the 909 geographic area may be assigned a new area code.

The majority of the area served by the 909 area code is in the southwestern portion of San Bernardino County, the eastern portion of Los Angeles County, and small portions of Orange and Riverside Counties. The 909 area code serves Big Bear Lake, Colton, Chino, Chino Hills, Fontana, Grand Terrace, Highland, Loma Linda, Montclair, Ontario, Rancho Cucamonga, Redlands, Yucaipa, as well as unincorporated areas in San Bernardino County; Claremont, Diamond Bar, Industry, La Verne, Pomona, San Dimas, Walnut, as well as unincorporated areas in Los Angeles County, and Calimesa and Eastvale, as well as unincorporated areas in Riverside County.

The CPUC will be holding local jurisdiction and public meetings on April 4 and 5, 2017, to inform the local jurisdictions and the public, and to hear concerns about adding a new area code to the 909 area code.
