Iowa Area Codes Pieces Of Information

The Iowa area code system was implemented on July 1, 1947. North American Numbering Plan Administrator (NANPA) is responsible for assigning Iowa area codes and telephone exchanges within the state.

The first three digits of every Iowa phone number are controlled by the NANPA. These digits are known as the Prefix or sometimes called an Exchange. The exchange is assigned to a specific geographic region. The next digit in an Iowa phone number is known as the Line or Trunk Group. This designates the type of service being used such as landline, VoIP, or cellular. The final four digits of an Iowa phone number are known as the Subscriber Number and are unique to each individual or business.

The area codes in Iowa are as follows: 319, 515, 563, 641, and 712. These codes are used to identify various locations within the state of Iowa. The first two digits of each code represent the general geographic area of the state, while the last four digits identify specific counties or towns within that area. For example, 319 is the code for Linn County, which is located in eastern Iowa. 515 is the code for Polk County, which includes the city of Des Moines. 641 is the code for Jasper County, which is located in central Iowa. Finally, 712 is the code for Woodbury County, which includes the city of Sioux City.

The most populous city in Iowa is Des Moines, which is located in area code 515. Other large cities in Iowa include Cedar Rapids (319), Davenport (563), Sioux City (712), and Iowa City (319). The largest area code by land area is 563, which covers the northeastern part of the state, including the cities of Davenport and Dubuque. The smallest area code by land area is 515, which covers the central part of the state, including the capital city of Des Moines.

If you need to know what city is in what area code, you can use our handy online tool. Just enter the area code and we’ll show you all of the cities in that area code.
