909 Area Code

On June 13, 2019, the California Public Utilities Commission (CPUC) adopted Decision 19-06-012, approving an overlay that will add the new 840 area code to the geographic region served by the 909 area code. The overlay will allow existing 909 area code customers to keep their telephone numbers and area code. However, customers will be required to dial “1” and the area code for all calls to and from telephone numbers with the 909 and 840 area codes when the overlay is effective. Consumer education will begin summer of 2020. The overlay will be effective in early 2021.

The price of a call will not change due to the overlay. Dialing “1” and the area code does not mean that a call is a toll or long distance call, as calling areas and rates will not change. What is a local call before the overlay will remain a local call after the overlay. Dialing “1” and the area code does not mean there will be a charge for the call. Calls to 911, as well as 211, 311, 411, 511, 611, 711 and 811 will not be affected, and will continue to be dialed with 3 digits.

Press Releases



On June 23, 2017, the North American Numbering Plan Administrator (NANPA) filed Application 17-06-020 with the CPUC to introduce a new area code to the area now served by the 909 area code, as the 909 area code is forecasted to be depleted of available prefixes by the 3rd quarter of 2021.

CPUC held public meetings on April 4 and 5, 2017 in Pomona, San Bernardino and Redlands. At the meetings, NANPA presented the overlay and split options for adding a new area code to the 909. Attendees asked questions and expressed their opinions at the public meetings, and were further provided an opportunity to submit written comments to the CPUC. Public comments were also submitted via email and postal mail to the CPUC Public Advisor’s Office. Concerns and questions expressed in the comments regard issues ranging from the 1 + 10-digit dialing procedure and public education to area code relief network implementation.

The 909 area code was created from the split of the 714 area code in November 1992. The 909 area code itself was split to form the 951 area code in 2004. The 909 area code serves the southwestern portion of San Bernardino County, the eastern portion of Los Angeles County, and small portions of Orange and Riverside Counties.

Cities served by the 909 area code include, in San Bernardino County, Big Bear Lake, Colton, Chino, Chino Hills, Fontana, Grand Terrace, Highland, Loma Linda, Montclair, Ontario, Rancho Cucamonga, Redlands, Yucaipa, and unincorporated areas; in Los Angeles County, Claremont, Diamond Bar, Industry, La Verne, Pomona, San Dimas, Walnut, and unincorporated areas; in Riverside County, Calimesa and Eastvale, and unincorporated areas; and in Orange County, a small portion of Yorba Linda.

The 909 area code is bordered on the north and east by the 760/442 area code overlay complex, directly to the west by the 626 area code, to the southwest by the 714/657 area code overlay complex, and to the south by the 951 area code.

Questions and comments concerning the 909/840 area code overlay may be submitted to the Public Advisor’s Office by:
