810 Area Code: Flint, Michigan

Eastern Michigan around the southern shore of Lake Huron is served by the 810 area code, with Flint as the primary city. Flint sits along the Flint River north of Detroit, on a stretch of country that supported one of the largest General Motors manufacturing complexes in the country through the mid-twentieth century. The city's working economy has reshaped substantially since the contraction of GM employment over the past several decades, with healthcare, education, and a smaller manufacturing base anchoring much of the current profile. The 810 footprint extends through Lapeer, Port Huron, the Thumb region of Michigan, and the surrounding eastern Michigan counties.

Records linked to 810 numbers in the directory often include Ann Arbor, Detroit, Grand Rapids, and Kalamazoo — Michigan cities outside the 810 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Michigan and addresses linked across multiple cities. The directory currently documents 345 distinct prefixes within 810 in detail, a working subset of the prefix population the code carries.

Flint's home values come in dramatically below the US median, with median household income running well below the national figure — both readings shaped heavily by the city's long-running economic transition since the contraction of automotive employment. The city's median age sits a few years under the US reading, and population is modest in absolute terms — the broader 810 footprint covers a substantial geographic stretch of eastern Michigan, including the small cities and farming counties of the Thumb.
