FAQs About 840 Phone Numbers
Is area code 840 a scam?
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.
Why do I get spam calls from area code 840?
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.
