About 504 Area Code
Area code 504 serves New Orleans and the surrounding metropolitan area. Established in 1947 as one of the original 86 North American area codes, 504 originally covered all of Louisiana before being split in 1957, 1998 and 2001. Today it covers Orleans, Jefferson, St. Bernard and Plaquemines parishes. The code supports local voice and SMS-capable numbers used by tourism operators, port operations, healthcare facilities, universities and cultural institutions throughout the Crescent City.
The 504 region blends tourism, port commerce, oil and gas, and healthcare sectors. The Port of New Orleans drives maritime trade and logistics demand, while Mardi Gras, Jazz Fest and convention traffic fuel hospitality operations. Major employers like Ochsner Health System, Tulane University and Entergy Corporation create steady telephony demand for patient outreach, admissions calls and customer support. Local businesses use 504 numbers because they deliver higher answer rates and stronger trust signals than toll-free or out-of-state alternatives, especially valuable in a city where culture and community connection matter.
FoneSwift lists live 504 inventory with real-time capabilities shown on this page. Search numbers to see Voice, SMS and MMS support.

How Does Local 504 Phone Numbers Work?
A local business number is a structured telephone identifier that tells networks where to route calls and messages. When you use a 504 number in New Orleans and Louisiana, the digits signal the international gateway, the geographic region, the local exchange and the specific subscriber, so calls reach the right destination quickly and reliably.

- Country code (+1): identifies United States for international routing.
- Area code (504): directs the call to the New Orleans / Louisiana region.
- Central office / exchange (eg. 555): narrows the call to a local switching area or rate center.
- Subscriber number (eg. 1234): the unique line assigned to a person, extension, or device.
