Is area code 248 a scam?
No. Area code 248 is a legitimate area code serving Troy since 1993. Scammers spoof caller ID to display 248 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 248 number, and the number they display may belong to a real business in Troy that has nothing to do with the call.

Area codes that overlay 248
Area code 248 shares its geographic footprint with one other code: 947. Overlays are laid over an existing area rather than splitting it, so all local calls require the full ten-digit number.
Troy is the business center of Oakland County, the affluent suburban county directly north of Detroit, and area code 248 has been its number since the code split off in 1993. The corridor along Big Beaver Road holds one of the largest concentrations of office space in Michigan, filled with automotive suppliers, engineering firms, banks, and corporate law offices. Automation Alley, the region's manufacturing and technology association, is headquartered in Troy, and the Somerset Collection mall anchors a retail economy that draws from the whole metro. This is where much of the auto industry's white-collar work gets done, even though no assembly plants run here.
Who lives in the 248 region
The city of 87,294 (2020 census) is small but unusually prosperous and international. Median household income was $120,045 in 2024, and 30.8 percent of residents were born outside the United States (Census ACS via Data USA). The Asian population, at roughly 24,400 people, is the city's second largest group, with deep Indian, Chinese, and Korean professional communities tied to automotive engineering. Statewide, Iraq ranks among the top origins for foreign-born residents, reflecting metro Detroit's large Chaldean community, much of it in Oakland County.
