The Geographical Location of Area Code 402
Area code 402 is a North American telephone area code that covers the eastern part of Nebraska in the United States. It was established in 1947 as one of the original area codes in the North American Numbering Plan (NANP), which was created to simplify the allocation of phone numbers across the continent.
The geographic location of area code 402 includes major cities such as Omaha, Lincoln, and Bellevue, as well as smaller communities throughout eastern Nebraska. The area code covers an area of approximately 41,000 square miles, encompassing 49 counties in the state.
To the north, area code 402 borders the 712 area code in Iowa, while to the east it is separated from the 712 and 660 area codes in Missouri by the Missouri River. To the south, it is adjacent to the 785 area code in Kansas, and to the west it shares borders with the 308 and 605 area codes in Nebraska and South Dakota, respectively.
Overall, area code 402 serves a diverse population of over 1.3 million people, including urban and rural areas, and is an important part of the telecommunications infrastructure in the region.
Cities and Counties Covered by Area Code 402
Area code 402 covers a wide range of cities and counties in eastern Nebraska. Some of the largest cities within the area code include:

History and Changes of Area Code 402
Area code 402 was one of the original area codes established in the North American Numbering Plan (NANP) in 1947. At that time, it covered the entire state of Nebraska, as well as parts of neighboring states. However, as the population of Nebraska grew, so did the demand for phone numbers, and area code 402 was split multiple times to create new area codes.
The first split occurred in 1954, when area code 308 was created to cover the western part of the state. Then, in 1998, area code 402 was split again, with the northern part of the state being assigned to the new 402 area code. This split created two separate numbering plan areas (NPAs) for Nebraska, with area code 402 covering the eastern and southern parts of the state, and area code 308 covering the western and northern parts.
Since then, there have been no further splits or changes to the area code 402 region. However, as with all area codes, the demand for phone numbers continues to grow, and it is possible that additional splits or overlays may be necessary in the future to ensure that there are enough numbers to meet the needs of the region.
Tips for Dealing with Unwanted Calls from Area Code 402
While area code 402 covers a large and diverse region of Nebraska, it is not immune to unwanted calls from telemarketers, scammers, and robocallers. If you receive an unsolicited call from an unknown number with area code 402, there are several steps you can take to protect yourself:
Don’t answer calls from unknown numbers: If you don’t recognize the number, let it go to voicemail or the answering machine. If it’s a legitimate call, the person will leave a message.
Block the number: If you receive multiple unwanted calls from the same number, block it on your phone or through your carrier’s website.
Report the call: If you receive a suspicious call from a number with area code 402, report it to the Federal Trade Commission (FTC) or the Federal Communications Commission (FCC).
Use call-blocking apps: There are many call-blocking apps available for smartphones that can help identify and block unwanted calls.
Be cautious with personal information: Never give out personal information over the phone to someone you don’t know. Scammers may try to trick you into revealing sensitive information like your Social Security number or credit card information.
By following these tips, you can help protect yourself from unwanted calls and potential scams originating from area code 402.
Understanding the North American Numbering Plan
The North American Numbering Plan (NANP) is a system that was created in 1947 to standardize the allocation of phone numbers across North America. It covers the United States, Canada, and several other territories and countries, and includes area codes, exchange codes, and subscriber numbers.
Under the NANP, each area code is assigned to a specific geographic region, such as a state or province, and is typically associated with a particular time zone. Within each area code, phone numbers are divided into exchange codes and subscriber numbers. The exchange code represents a specific central office or exchange that serves a particular area, while the subscriber number identifies the individual phone line within that exchange.
As populations have grown and the demand for phone numbers has increased, the NANP has undergone numerous changes, including the creation of new area codes and the implementation of number pooling, which allows multiple carriers to share a single block of phone numbers.
Today, the NANP covers over 20 countries and territories, and is an important part of the telecommunications infrastructure throughout North America. Understanding how the NANP works and how area codes are assigned can help individuals and businesses navigate the complex world of modern telecommunications.
