318 Area Code: Shreveport, Louisiana

North Louisiana is served by the 318 area code, with Shreveport as the primary city. Shreveport sits along the Red River in the northwest corner of the state, organized around a downtown that has worked through a long reorientation since the closure of Barksdale Air Force Base's broader contractor base years ago — though the base itself remains active immediately east of the city. The local working economy reflects a substantial healthcare sector, the gaming industry that has anchored the riverfront since the 1990s, and the surrounding oil-and-gas activity in the broader Ark-La-Tex region. The 318 footprint extends to Monroe, Alexandria, and the parishes of north Louisiana.

In records the directory has compiled for 318 numbers, other Louisiana cities — Baton Rouge, Houma, Lafayette, and New Orleans — recur frequently. None of those are inside the 318 footprint. The pattern reflects standard public-record dynamics, with phone numbers porting across Louisiana and addresses linked across multiple cities. The directory currently documents 530 distinct prefixes within 318 in detail, a working subset of the prefix population the code carries.

Shreveport's home values come in well below the US median, in line with broader north Louisiana pricing. Median household income runs below the national figure, the city's median age sits close to the US reading, and population places Shreveport among the larger Louisiana cities — substantial enough to anchor a regional economy that combines healthcare, gaming, and the surrounding oil-and-gas activity. The broader 318 footprint reflects a mix of mid-sized cities and rural parishes spread across the northern half of the state.
