The Louisiana Public Service Commission has approved area code 457 as an all services overlay of area code 318 with an implementation date of 09/25/2025. Area code 457 will only become available to subscribers when all assignable central office codes in area code 318 are assigned. Ten digit dialing (area code + seven digit number) will be necessary in the 318/457 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
