How Louisiana's area codes began

For 10 years, 504 was the only area code in Louisiana, until 318 opened in 1957.

1. 1947: 504 was among the first area codes issued in 1947, for Jesuit Bend, Kenner, plus Lafitte.
2. 1957: a new area code, 318, opened for Alexandria, Arcadia and Athens.
3. 1998: 225 split away from 504, covering Albany, Baton Rouge and Clinton.
4. 1999: 337 broke away from 318, covering Abbeville, Arnaudville and Baldwin.
5. 2001: 985 split away from 504, covering Amite City, Angie and Bogalusa.
6. 2025: 457 came in as an overlay on 318, covering the same area.

Making calls in Louisiana

Local calls in 504, 318, 337 and 457 take 10-digit dialling; long-distance calls take 1 + 10-digit dialling.

For 225 and 985, local calls require 7-digit dialling, while long-distance calls require 1 + 10-digit dialling.

Among the 378 US area codes in service, only 54 still permit 7-digit local calls.
