The Louisiana Public Service Commission has approved an overlay adding the 457 area code to the existing 318 area code region covering northern Louisiana. Starting August 25, 2025, all local calls within the 318 area code region must be dialed using 10 digits (area code + 7-digit telephone number). A six-month permissive dialing period begins February 24, 2025, during which local calls can be completed with either 7 or 10 digits. All customers should prepare for the transition, and certain equipment programmed for 7-digit dialing must be reprogrammed.
