515 Area Code: Des Moines, Iowa

Iowa's 515 area code covers central Iowa, with Des Moines — the state capital — as its primary city. Des Moines sits at the confluence of the Des Moines and Raccoon rivers, on the gently rolling country of central Iowa, organized around a downtown that holds the Iowa State Capitol and a substantial concentration of insurance-industry employment. The city's working profile reflects state government, a long-running insurance and finance sector (Principal Financial Group is headquartered downtown), and a substantial agricultural-services base. The 515 footprint extends to Ames (and Iowa State University's main campus), Boone, and the surrounding central Iowa counties.

In records the directory has compiled for 515 numbers, other Iowa cities — Cedar Rapids, Davenport, Marshalltown, and Sioux City — recur frequently. None of those are inside the 515 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Iowa and addresses linked across multiple cities. The directory currently documents 363 distinct prefixes within 515 in detail, a working subset of the prefix population the code carries.

Des Moines's home values come in below the US median, with median household income running below the national figure but not severely so. The city's median age sits a few years under the US reading, and population places Des Moines among the larger Midwestern state-capital cities — substantial enough to anchor a metropolitan area that pulls steadily on populations from across central Iowa.
