No, 350 is a legitimate area code serving the San Joaquin Valley in California, including Stockton and Modesto. Because it is a relatively new overlay, spoofers exploit the fact that many people cannot immediately place it.
Scammers dial from 350 numbers because the overlay is young enough that spam databases have not fully catalogued it. Reported calls include fake debt collectors threatening legal action and unsolicited robocalls designed purely to confirm that a number is active before selling it to larger fraud networks.
Phone numbers with the 350 area code originate from communities within the northern San Joaquin Valley, which is part of California's Central Valley, and also portions of the Sierra Foothills.
Area code 350 was assigned on November 28, 2022, forming an overlay complex with area code 209 . This measure was taken to address the impending central office code exhaustion in the 209 numbering plan area due to growth in telecommunication services. As ten-digit dialing was already in effect for the 209 area code prior to 350's introduction, network preparation was expedited without a permissive dialing period.
Area code 350 is a general purpose code which was placed in service on November 28, 2022.
