Louisiana has 64 counties spread across its territory.
Each area code in LA covers a geographic region of the state, with some areas using overlay codes that share the same geographic territory as an existing area code.
When calling a Louisiana phone number from outside the area code, you must dial the full 10-digit number: the 3-digit area code followed by the 7-digit local number.
Many parts of Louisiana now require 10-digit dialing even for local calls due to overlay area codes and the nationwide 988 Suicide & Crisis Lifeline implementation.
