'''Area code 515''' is a telephone [area code](/source/area_code) in the [North American Numbering Plan](/source/North_American_Numbering_Plan) (NANP) for most of the north-central part of the [U.S. state](/source/U.S._state) of [Iowa](/source/Iowa). The numbering plan area includes [Des Moines](/source/Des_Moines%2C_Iowa), [Ames](/source/Ames%2C_Iowa), [Ankeny](/source/Ankeny%2C_Iowa), [Humboldt](/source/Humboldt%2C_Iowa), [Boone](/source/Boone%2C_Iowa), [Fort Dodge](/source/Fort_Dodge%2C_Iowa), [Jefferson](/source/Jefferson%2C_Iowa), [Johnston](/source/Johnston%2C_Iowa), [Urbandale](/source/Urbandale%2C_Iowa), [Algona](/source/Algona%2C_Iowa) and [Indianola](/source/Indianola%2C_Iowa).

Despite its relatively low population, Iowa was originally divided into three numbering plan areas (NPAs), with each border line running roughly in north–south directions.

Area code 515 originally served the central part of the state, stretching border to border from [Minnesota](/source/Minnesota) to [Missouri](/source/Missouri). In 2000, the eastern and southern portions of the area were split off with [area code 641](/source/area_code_641), leaving 515 with only about one-fourth of its original area, including Des Moines and the area northwest of the city. Only one small portion in the north of the numbering plan area borders another state, Minnesota.

Prior to October 2021, area code 515 had telephone numbers assigned for the [central office code](/source/central_office_code) 988. In 2020, ''988'' was designated nationwide as a dialing code for the [National Suicide Prevention Lifeline](/source/National_Suicide_Prevention_Lifeline), which created a conflict for exchanges that permit [seven-digit dialing](/source/seven-digit_dialing). This area code was therefore scheduled to transition to [ten-digit dialing](/source/ten-digit_dialing) by October 24, 2021.<ref name="pl556">{{cite web|url=https://nationalnanpa.com/pdf/PL_556.pdf|date=January 8, 2021|publisher=North American Numbering Plan Administrator |title=Transition to 10-digit dialing (for 988 as 3-digit access to National Suicide Prevention Hotline)|access-date=March 9, 2021}}</ref>

The heavy metal music band [Slipknot](/source/Slipknot_(band)), being from Des Moines, named the song "[(515)](/source/(515))" in the album ''Iowa'' after the area code.
