402 Area Code: Omaha, Nebraska

Eastern Nebraska is served by the 402 area code, with Omaha as the primary city. Omaha sits along the Missouri River on the eastern edge of the state, organized around a downtown that has reshaped itself substantially over the past two decades alongside a substantial concentration of corporate headquarters — Berkshire Hathaway, Mutual of Omaha, Union Pacific, and several large insurance and banking firms. The 402 footprint covers Omaha along with Lincoln (the state capital and home to the University of Nebraska's main campus), Bellevue, Fremont, and the surrounding eastern Nebraska counties.

In records the directory has compiled for 402 numbers, Grand Island — a city in central Nebraska — appears regularly despite lying outside the 402 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Nebraska and addresses linked across multiple cities. The directory currently documents 577 distinct prefixes within 402 in detail, a working subset of the prefix population the code carries.

Omaha's home values come in below the US median, with median household income running close to the national figure. The city's median age sits a few years under the US reading, and population places Omaha as the largest city in Nebraska and one of the larger cities along the upper Missouri corridor — substantial enough to anchor a metropolitan area that extends across the river into Iowa and pulls steadily on populations from across eastern Nebraska and western Iowa.
