586 Area Code: Warren, Michigan

Northern Macomb County and the surrounding eastern suburban Detroit corridor are served by the 586 area code, with Warren as the primary city in the directory's records. Warren sits immediately north of the Detroit city line in Macomb County, organized around the General Motors Technical Center and a substantial cluster of automotive engineering, manufacturing, and supplier operations that have anchored the city's working economy for decades. The 586 footprint reaches through Sterling Heights, Roseville, St. Clair Shores, Mount Clemens, and the surrounding cluster of Macomb County cities and townships.

Records linked to 586 numbers in the directory often include Ann Arbor, Detroit, Flint, and Grand Rapids — Michigan cities outside the 586 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Michigan and addresses linked across multiple cities. The directory currently documents 371 distinct prefixes within 586 in detail, a working subset of the prefix population the code carries.

Warren's home values come in below the US median, with median household income running below the national figure but not severely so. The city's median age sits close to the US reading, and population places Warren as one of the larger cities in Michigan — substantial enough to anchor its share of the broader Macomb County metropolitan corridor. The 586 footprint as a whole reflects a long-running mix of postwar suburban development, automotive engineering, and the surrounding lakefront communities along Lake St. Clair.
