Is area code 840 a scam?
No. Area code 840 is a legitimate area code serving San Bernardino since 2020. Scammers spoof caller ID to display 840 numbers, which is why complaints exist against a code that is itself genuine.
Neighbour spoofing is the reason a local-looking number is not a guarantee. A caller anywhere in the world can display a 840 number, and the number they display may belong to a real business in San Bernardino that has nothing to do with the call.

Area codes that overlay 840
Area code 840 shares its geographic footprint with one other code: 909. Overlays are laid over an existing area rather than splitting it, so all local calls require the full ten-digit number.
Area code 840 overlays 909 in the Inland Empire, in service since 2020, with San Bernardino, California among its principal cities. This is logistics country. Transportation and warehousing is the largest employment sector at 14,340 workers, and material moving is the single most common occupation at 12,316 people (Data USA, 2024). The warehouses that feed Los Angeles and the ports of Long Beach and San Pedro line the freeways here, and BNSF's intermodal yard in San Bernardino is one of the busiest in the western United States. Retail trade and health care fill out the employment base, with the county government and Cal State San Bernardino among the stabler employers.
Who lives in the 840 region
The city held 222,724 people in 2024, and 70.2 percent of residents are Hispanic, with 23.3 percent of the population born outside the United States (Data USA, 2024). Spanish is a working language of commerce, not a translation afterthought. Median household income reached $67,415 and grew 5.4 percent in a year, while the median property value of $422,300 is low by Southern California standards, which is precisely why the population keeps growing. Commutes average 29.7 minutes, many of them toward jobs in Los Angeles and Orange counties.
What an 840 number signals to a caller
An 840 number is recent, and the 909 it overlays has covered the Inland Empire since 1992, long enough that "the 909" became regional shorthand, sometimes used dismissively by coastal Californians and worn with some defiance locally. Callers describe business conduct as practical and schedule-driven, shaped by warehouse shifts and freight windows. Bilingual capability is often an asset on the line. An outside caller who assumes coastal LA norms apply here misreads the market.
