Area code 504 is one of the original area codes created in 1947 and serves the New Orleans metropolitan area in southeastern Louisiana. Once covering all of southern Louisiana, it was gradually reduced with the introduction of 985 in 2001. 504 is deeply associated with the unique culture, history, and music of New Orleans. It’s a staple in Mardi Gras branding, jazz heritage, and local business identities. The area is home to world-famous landmarks like the French Quarter, Bourbon Street, and the Superdome. Despite natural disasters like Hurricane Katrina, the 504 community has remained resilient, and the area code has become a badge of cultural and civic pride.
