417 Area Code: Springfield, Missouri

Southern Missouri is served by the 417 area code, with Springfield as its primary city. Springfield sits on the Springfield Plateau in the southwestern Missouri Ozarks, organized around a downtown core, Missouri State University, and a substantial healthcare sector centered on the Mercy and CoxHealth hospital systems. The city's working profile also reflects its role as the headquarters of Bass Pro Shops and a regional commercial center for a wide stretch of the Ozarks. The 417 footprint extends through Joplin, Branson (the country-music tourism corridor), Lebanon, and the surrounding southern Missouri counties.

Records linked to 417 numbers in the directory often include Columbia, Kansas City, O'Fallon, and Sedalia — Missouri cities outside the 417 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Missouri and addresses linked across multiple cities. The directory currently documents 458 distinct prefixes within 417 in detail, a working subset of the prefix population the code carries.

Springfield's home values come in below the US median, with median household income running well below the national figure. The city's median age sits a few years under the US reading, and population places Springfield among the larger cities in southern Missouri — substantial enough to anchor a regional economy organized around healthcare, the universities, and the surrounding Ozarks tourism corridor. The broader 417 footprint reflects a mix of mid-sized cities and the rural counties spread across the southwestern third of the state.
