About Area Code 402
Area code 402 is a North American Numbering Plan (NANP) area code that has been in service since 1947. It is administered by NANPA on behalf of the FCC and serves the Nebraska region anchored on Omaha.
402 now shares its territory with an overlay code (531). 10-digit dialling is required for local calls within this region because the same 7-digit number can be assigned under either code.
Mobile numbers in 402 are portable: a person who moved away from Omaha may still carry a 402 mobile number on their device. If you receive an unexpected call from a 402 number, run it through the reverse lookup tool above for the most accurate, free identification.
If you live or do business in Nebraska, you may also interact with neighbouring or overlay codes (531). See the related codes section below to explore the rest of Nebraska.
