274 Area Code: Green Bay, Wisconsin

Wisconsin's 274 area code is among the newer overlays planned for the eastern part of the state, sharing geography with the long-running 920 across northeastern Wisconsin. Green Bay anchors the directory's records here. Green Bay sits at the head of the bay that gives the city its name, on a stretch of Lake Michigan's western shore that has long anchored the city's working profile — a substantial paper-and-pulp industry has shaped much of the local economy for over a century, alongside the famously long-running Green Bay Packers football franchise. The 274 designation, part of the North American Numbering Plan, is in the early phases of being prepared for active number assignments.

In records the directory has compiled for 274 numbers, other Wisconsin cities — Eau Claire, Kenosha, Madison, and Milwaukee — appear regularly. None of those are inside the 274 footprint. The pattern reflects standard public-record dynamics across Wisconsin. The directory's prefix-level holdings for 274 remain in early stages, with current coverage representing the start of working records rather than a comprehensive count of the prefix population the code will eventually carry.

Green Bay's home values come in below the US median, with median household income running below the national figure. The city's median age sits a few years under the US reading, and population places Green Bay among the larger cities in northeastern Wisconsin. The 274 footprint shares those demographics with 920 because both codes serve northeastern Wisconsin in overlapping form, and the broader region reflects a long-standing mix of mid-sized cities, paper-industry communities, and the surrounding rural counties of east-central Wisconsin.
