Area codes and dialing in Louisiana
Louisiana's 5 area codes mix older geographic codes with newer overlays. The busiest metros — around Baton Rouge, Houma, Lafayette — carry the most numbers and rely on overlays, which is why dialing rules vary by area. Quieter parts of the state may still use a single code. The original code in the Louisiana list is 225 (Baton Rouge).
Whenever a Louisiana region runs low on numbers, a new overlay is added on top rather than splitting the map, so existing customers keep their numbers. See 10-digit dialing for what that means in practice, or the newest area codes for upcoming changes.
