What Is the 274 Area Code?
The 274 area code is a telephone area code in the North American Numbering Plan (NANP), designated as an overlay for the established 920 code in eastern Wisconsin. Unlike a geographic split — where one code takes over part of a region — an overlay means both 274 and 920 serve the exact same territory. A business in Green Bay can hold either a 920 or a 274 number, and both reach the same local audience.
Because 274 is an overlay, ten-digit dialing became mandatory across the entire 920/274 region. Every local call now requires the full ten-digit number. The 274 code went live on May 5, 2023 — after more than a decade of planning delays — making it one of the youngest telephone prefixes in the country.
Where Is the 274 Region Located?
The 274 zone covers the eastern and northeastern portions of Wisconsin, a corridor anchored by Lake Michigan on the east and extending inland through the Fox Valley to Lake Winnebago. The territory stretches from the Illinois state border in the south up through Door County's scenic peninsula in the north — roughly 22,000 square miles across 19 counties.
Green Bay anchors the northern half of the corridor, Appleton drives commercial activity through the Fox Valley's midpoint, and Sheboygan holds down the Lake Michigan shoreline to the south. The result is a geographically diverse market blending industrial production, agricultural land, Great Lakes tourism, and growing professional services.
Geographic Boundaries of the 274 Zone
The 274 footprint runs from Dodge and Jefferson counties in the south through Kewaunee and Oconto counties in the north. Manitowoc and Sheboygan sit directly on Lake Michigan's shoreline, while Fond du Lac anchors Lake Winnebago's southern tip. Door County — Wisconsin's thumb-like peninsula reaching into Lake Michigan — rounds out one of the state's most scenic and varied service territories.
Major Cities and Communities
More than 163 cities and towns carry 274 numbers across 19 counties. Here are the standouts:
Green Bay — Wisconsin's third-largest city and home to the Green Bay Packers. Green Bay anchors the northeast with strong healthcare, manufacturing, and professional services employment.
Appleton — The commercial center of the Fox Valley, Appleton hosts major insurance and paper manufacturing firms, Lawrence University, and holds the distinction of being the birthplace of Harry Houdini.
Oshkosh — Home to EAA AirVenture (the world's largest airshow) and Oshkosh Corporation. UW-Oshkosh adds a steady pipeline of professional talent to the local economy.
Sheboygan — A Lake Michigan port city known for bratwursts, an award-winning arts district, and Kohler Co.'s global headquarters in the adjacent village of Kohler.
Fond du Lac — A key Fox Valley hub with strong manufacturing and distribution employers, sitting at the south end of Lake Winnebago.
Manitowoc — A historic Lake Michigan port known for aluminum manufacturing, the National Submarine War Memorial, and Wisconsin's deep maritime heritage.
Other communities served include Sturgeon Bay, Beaver Dam, Watertown, Ripon, Berlin, Fort Atkinson, Waupaca, Two Rivers, and dozens more across the 19-county footprint.
Teams covering the full Great Lakes manufacturing corridor often complement a 274 number with the 269 area code for simultaneous reach into southwestern Michigan.

Central Time Zone — Scheduling Calls Into 274
The 274 area code region follows Central Time (CT) — the same zone as Chicago, Dallas, and Minneapolis. In winter this is Central Standard Time (CST) at UTC-6. During daylight saving months, the region observes Central Daylight Time (CDT) at UTC-5.
For teams calling into 274 from other time zones, here is what that offset means:
- From Eastern Time (ET): the 274 region is 1 hour behind.
- From Mountain Time (MT): the 274 region is 1 hour ahead.
- From Pacific Time (PT): the 274 region is 2 hours ahead.
Business hours in eastern Wisconsin run from 9 AM to 5 PM Central Time. East Coast teams should plan calls before 4 PM Eastern to reach Green Bay and Appleton contacts before their workday ends.
History of Area Code 274
The story behind area code 274 stretches back to 2008, when network planners first identified that area code 920 would eventually exhaust its available number supply. The Wisconsin Public Service Commission approved an overlay plan with a target launch of March 2012. Two successive delays followed — the first in December 2010, when revised demand forecasts pushed the timeline back, then a second postponement that left the code in planning limbo for over a decade.
By 2022, sustained growth in mobile subscriptions, business expansions, and connected devices finally pushed 920 to its limit. The 274 code formally entered service on May 5, 2023 — nearly fifteen years after the first plan was drawn up.
Today it shares eastern Wisconsin with 920, a young prefix paired with a well-established one. For businesses, this means there is still a strong selection of 274 numbers available — an early-mover advantage that will narrow as more organizations claim local Wisconsin digits. The overlay approach mirrors what Michigan's 248 area code region experienced in 2001 when area code 947 was introduced to handle the same surge in Oakland County.
Scam Calls in the 274 Zone — What to Watch For
As with many newly activated codes, scammers have begun spoofing 274 to make their calls look locally sourced in Wisconsin. Because the prefix is still unfamiliar to many recipients, it lowers the guard that a well-known number might raise — and fraudsters exploit that gap.
Common scam types reported in the 274 and 920 region include:
- Business impersonation and Google Listing scams — callers claiming to manage your company's online visibility
- Aggressive health insurance pitches — unsolicited coverage offers targeting Wisconsin residents
- Fake police and firefighter charity drives — callers posing as first-responder fundraising organizations
- Vehicle warranty calls — unsolicited car protection plan offers
- Fake legal and debt collection threats — callers impersonating attorneys or collection agencies
If a call from a 274 number you do not recognize asks for personal or financial information, end the call and verify the caller independently. The great majority of calls from this prefix are legitimate — local businesses, schools, healthcare providers, and Wisconsin residents.
Suspected 274 scam calls can be reported to the FTC at reportfraud.ftc.gov to help investigators shut down spoofing operations targeting eastern Wisconsin residents.
