The 402 area code serves eastern Nebraska, including the state’s two largest cities – Omaha and the capital, Lincoln. One of the original area codes assigned in 1947, 402 covers the most populous part of the state and shares its footprint with the 531 overlay.
Quick Summary of the 402 Area Code

| State | Nebraska (NE) |
| Region | Eastern Nebraska (Omaha & Lincoln Metro) |

Geographic Coverage
The 402 area code covers eastern Nebraska, centered on Omaha and its suburbs of Bellevue, Papillion, and La Vista, and the capital city of Lincoln to the southwest, along with Fremont, Norfolk, and Columbus to the north and west. It runs along the Missouri River and the Iowa border and shares its footprint with the 531 overlay.
Time Zone
The 402 area code observes Central Time (CT). Clocks follow Central Standard Time (UTC−6) in winter and shift to Central Daylight Time (UTC−5) from mid-March through early November. Eastern Nebraska, including Omaha and Lincoln, is on Central Time, though the western Panhandle of the state observes Mountain Time. From the West Coast, this region is two hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 402 number at 11:00 AM local time.
Tip: Business hours across the 402 region generally run 9:00 AM to 5:00 PM local time, Monday through Friday.
How to Dial a 402 Number
Because area code 402 operates as part of an overlay, 10-digit dialing is mandatory for every local and long-distance call. You must dial the full 10-digit number (402 + the seven-digit line number) even when calling a neighbor across the street. For international callers, dial your country’s exit code, then +1 (the North American country code), then 402, followed by the seven-digit local number.
Scam Alerts for the 402 Area Code
Like every U.S. area code, 402 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Omaha, Lincoln, Bellevue, Papillion, La Vista, Fremont, Norfolk, Columbus should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers claiming you owe back taxes and threatening arrest unless you pay immediately. |
| Utility Shut-off | Fake OPPD or LES reps demanding payment to avoid disconnection. |
| Bank Fraud Alerts | Robocalls impersonating your bank about “suspicious activity” to phish account details. |
| Grandparent Scam | A caller posing as a relative in trouble asking for emergency wire transfers. |
If you receive a suspicious call from a 402 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Nebraska Attorney General’s Consumer Protection Division.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (OPPD, LES, or NPPD) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 402 caller making such a demand is a scammer.
History and Economy of the 402 Region
n
Area code 402 is one of the original 86 codes established in 1947, and it once covered all of Nebraska before 308 was split off in 1954. As the Omaha-Lincoln corridor grew, the 531 overlay was added in 2011 across the same territory. Omaha anchors the regional economy as a major finance and insurance center – home to Berkshire Hathaway and Warren Buffett, Mutual of Omaha, and the headquarters of Union Pacific Railroad – along with healthcare, agribusiness, and Offutt Air Force Base, home of U.S. Strategic Command. Lincoln adds state government, the University of Nebraska, and a growing insurance and technology sector.

To identify a 402 caller, use a reverse phone lookup service or search the full 10-digit number online. Many Omaha and Lincoln businesses, government offices, and healthcare providers list their 402 numbers publicly, so a quick search often confirms a legitimate caller. For unknown numbers, let the call go to voicemail – genuine callers usually leave a message.
