Is area code 350 a scam?
No. Area code 350 is a legitimate area code serving Stockton since 2024. Scammers spoof caller ID to display 350 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 350 number, and the number they display may belong to a real business in Stockton that has nothing to do with the call.

Area codes that overlay 350
Area code 350 shares its geographic footprint with one other code: 209. Overlays are laid over an existing area rather than splitting it, so all local calls require the full ten-digit number.
Stockton is the largest city in California's San Joaquin Valley north of Fresno, with 320,804 residents at the 2020 census and a metro GDP of $33.1 billion (U.S. Bureau of Economic Analysis, 2023). Its economy is built on moving and growing things. The Port of Stockton is an inland deepwater seaport reaching the Pacific through the Delta, and the surrounding county is one of the most productive farm regions in the country, with wine grapes, almonds, walnuts, and cherries leading the ledger. In the last decade, warehousing and distribution boomed as Amazon and other logistics operators put fulfillment centers along Highway 99 and I-5 to serve the Bay Area and Sacramento at Valley costs. The University of the Pacific and two hospital systems round out the employer base.
Who lives in the 350 region
The city is one of the most diverse in the United States. Hispanic residents make up 45.6% of the population, the Asian community numbers about 67,000, and 26.5% of residents were born outside the country (DataUSA, 2024). Spanish is the most common language after English, followed by Tagalog and Southeast Asian languages including Khmer and Hmong, legacies of the large Filipino and Cambodian communities that have shaped Stockton for generations. Median household income was $79,907 in 2024, lifted partly by Bay Area commuters who moved east for affordable housing.
What a 350 number signals to a caller
Area code 350 is one of California's newest, overlaid on 209 in 2024, so many locals are still getting used to seeing it. A 350 number is fully local across the northern San Joaquin Valley, from Stockton and Modesto to Merced, but callers describe some residents treating unfamiliar new codes with suspicion until they recognize them. An outside caller should know that ten-digit dialing is mandatory here, that multilingual capability matters in this market more than in most, and that a large share of the workforce keeps early agricultural and warehouse hours.
