Shreveport, LA Area Codes

Area codes serving Shreveport

Shreveport sits in Louisiana, part of the South region and the Central Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 318, 457.

The original code is 318 (in service since 1957). As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.

Code	Area served	In service
318	Northern and central Louisiana including Shreveport, Monroe and Alexandria	January 1, 1957
457	Northern and central Louisiana including Shreveport, Monroe and Alexandria	September 25, 2025

How to pick an area code for a new number

When you activate a new line in Shreveport, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 318), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.

Dialing in Shreveport

Because Shreveport is an overlay area, 10-digit dialing is mandatory: always dial the area code plus the seven-digit number, even for a neighbor. See 10-digit dialing and overlay area codes for the background. For every code in Louisiana, visit the Louisiana area codes page.
