Area code 840 covers a region in Southern California, specifically including portions of Los Angeles County, San Bernardino County, and Riverside County.
Area code 840 is an overlay to area code 909 . This means that both area codes serve the same geographic region. Area code 909 was created in 1992, and area code 840 was added in 2021. Ten-digit dialing is required for all calls in this region.
No, 840 is a valid area code implemented as an overlay for the 909 region in Southern California, covering San Bernardino and Fontana. Spoofing software allows international fraud rings to project this inland prefix to simulate a community connection.
Because this code mirrors the exact footprint of its parent region, residents face the same intense utility and government impersonation threats. Scammers aggressively target locals with spoofed Southern California Edison calls demanding immediate Zelle payments to prevent power disconnections. The area also suffers from constant fake legal couriers threatening to serve court summonses at your workplace.
