Area code 504 serves southeastern Louisiana, including New Orleans and its immediate suburbs. One of the original area codes established in 1947, it is deeply embedded in the identity of the region. Following Hurricane Katrina in 2005, the 504 area became even more symbolic of resilience, recovery, and cultural pride. Today, it continues to represent the heartbeat of Louisiana’s music, cuisine, and Creole heritage. Ten-digit dialing is required. Area code 504 is one of the most iconic in the U.S., synonymous with New Orleans and a powerful emblem of Southern culture, strength, and vibrancy.
