The 504 area code is an area code used in the United States for the state of Louisiana. This code was one of the original area codes assigned in 1947 when the North American Numbering Plan (NANP) was created.

The 504 area code is symbolic of the New Orleans metropolitan area, which includes parts of the southeast Louisiana parishes of Jefferson, Orleans, Plaquemines, St. Bernard, and St. Tammany. Although the 504 area code is still the main area code for this region, parts of Jefferson Parish have been issued a new area code, 318. With the introduction of this new area code, residents with numbers in the 504 area code may need to dial “1” followed the area code when making a call.
