Area code 504

Area code 504 serves Louisiana, including New Orleans, Kenner and Lafitte (Central time). It has been in service since January 1, 1947.

Numbers starting with 504 drew 1,048 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 649 complaints to the FCC since November 2023. The number on your screen can be faked, so a 504 number proves nothing about where a call came from.

Phone companies holding 504 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 66% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
