History of Area Code 274
Area code 274 was introduced in 2024 as an overlay for area code 920. It was created to add telephone-number capacity as demand for numbers increased in northeastern and east-central Wisconsin. Area code 274 was not created through a geographic split.
Area code 920 began service in 1997 after Wisconsin’s former 414 area was divided. The 274 overlay kept the existing 920 boundaries in place. Existing customers kept their telephone numbers, while new numbers in the same region could receive either 920 or 274. Calls within the overlay use ten-digit dialing.
