Is area code 925 a scam?
No. Area code 925 is a legitimate area code serving Concord since 1998. Scammers spoof caller ID to display 925 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 925 number, and the number they display may belong to a real business in Concord that has nothing to do with the call.

Who works in the Concord area?
Area code 925 covers the inland East Bay, the string of Contra Costa and Alameda County communities east of the Oakland hills, and Concord is its largest city. The economy is white-collar suburban with pockets of heavyweight science. Chevron is headquartered in San Ramon at the southern end of the code, alongside the Bishop Ranch business park that hosts offices for AT&T, Toyota, and dozens of others. Lawrence Livermore National Laboratory in Livermore employs thousands of scientists and engineers on national security research, and Sandia's California campus sits next door. Concord itself functions as the retail and services hub of central Contra Costa County, with John Muir Health as a major employer and a large financial back-office presence that has cycled through the city's office towers for decades.
Who lives in the 925 region
Concord had 124,035 residents in 2024, with a median household income of $108,709 and a median property value of $797,600 (DataUSA). The poverty rate was 8.24 percent, homeownership was 61.6 percent, and 25.1 percent of residents were born outside the country, with a Hispanic population of 32.4 percent (DataUSA, 2024). The average commute of 32.6 minutes tells the underlying story: many 925 households earn their living over the hills in Oakland or San Francisco.
What a 925 number signals to a caller
A 925 number reads as East Bay suburbs, the family-and-commuter side of the Bay Area rather than the urban core. Callers describe the tone as more relaxed than San Francisco but still Californian in its informality, and appointments beat cold calls in a market of dual-income households that are rarely home midday. The region runs on Pacific Time. For home services, healthcare, and financial outreach, early evening and Saturday mornings are generally the windows locals answer, and Spanish-language capability is a practical advantage in Concord's consumer market.
