Is area code 734 a scam?
No. Area code 734 is a legitimate area code serving Ann Arbor since 1997. Scammers spoof caller ID to display 734 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 734 number, and the number they display may belong to a real business in Ann Arbor that has nothing to do with the call.

Who works in the Ann Arbor area?
Area code 734 was carved out of 313 in 1997 and covers Ann Arbor and the corridor between Detroit and the Ohio line. The economic engine is the University of Michigan, which shapes nearly everything in the local numbers. Educational services was by far the largest employment sector in 2024 at roughly 20,500 workers, followed by healthcare through Michigan Medicine and professional, scientific, and technical services at about 8,000 (Data USA). Around the university sits a dense startup and research economy: software, biotech, and automotive R&D firms that draw on university labs, plus the metro's $30.6 billion GDP as of 2022 (U.S. Bureau of Economic Analysis).
Who lives in the 734 region
Ann Arbor's 122,036 residents (Data USA, 2024) skew educated and international. The foreign-born share is 18.5 percent, well above the Michigan average, driven by graduate students and research staff. Chinese, Korean, and Hindi are the non-English languages a caller is most likely to encounter in professional settings here, reflecting the university's large Asian and South Asian communities, and Michigan's foreign-born population statewide is led by people born in Mexico, India, and Iraq (Data USA, 2024). Median household income was $82,212 in 2024 against a median property value of $453,400, one of the highest in the state.
