The 504 Area Code: Complete Guide to New Orleans and Southeast Louisiana

• Area code 504 is one of the original 1947 NANP codes; it once covered all of Louisiana before multiple splits created 318 (1971), 225 (2001), 337 (2001), and 985 (2001).

What Is the 504 Area Code?

The 504 area code is a NANP (North American Numbering Plan) geographic area code assigned to southeast Louisiana and the New Orleans metropolitan area. It is one of the original area codes established in 1947 when the North American Numbering Plan first divided the continent into geographic numbering zones. At that time, 504 covered the entire state of Louisiana. Over the following decades, Louisiana's growing population and expanding telecommunications demand led to a series of geographic splits. In 1971, area code 318 was split off to serve northern Louisiana. The most significant round of splits came in 2001, when area codes 225, 337, and 985 were all created simultaneously, leaving the 504 area code to serve the compact New Orleans immediate metro of four parishes.

The 504 area code today defines one of the most culturally distinctive urban markets in the United States. New Orleans — the anchor of the 504 footprint — is the birthplace of jazz, the home of Mardi Gras, and one of the most visited cities in North America. The Port of New Orleans, one of the busiest and most strategically important ports in the United States, drives a massive logistics and shipping economy across the 504 region. Jefferson Parish, which surrounds New Orleans to the west and south, is home to Metairie and Kenner — two of Louisiana's largest suburban communities — as well as Louis Armstrong New Orleans International Airport.

Where Is the 504 Area Code Located?

The 504 area code covers southeast Louisiana, forming a compact crescent-shaped region between the Mississippi River, Lake Pontchartrain, and the Gulf of Mexico. It is bounded by area code 985 (Northshore communities and Houma-Thibodaux corridor) to the north and west, area code 225 (Baton Rouge metro) further to the northwest, and the Gulf of Mexico and Mississippi River delta to the south and east. The region centers on four Louisiana parishes: Orleans Parish (New Orleans proper), Jefferson Parish (Metairie, Kenner, Gretna, Harvey, Marrero, Westwego), St. Bernard Parish (Chalmette, Violet, Meraux), and Plaquemines Parish (Belle Chasse, Port Sulphur).

What Time Zone Does the 504 Area Code Use?

Every city in the 504 area code operates in the Central Time Zone — the same time zone as Chicago, Dallas, and Houston. During Central Standard Time, which runs from November through mid-March, clocks are set to UTC−6. During Central Daylight Time — mid-March through November — the region moves to UTC−5.

For businesses and callers on the East Coast, the 504 area code runs one hour behind New York and Washington D.C. For callers on the West Coast, the 504 region is two hours ahead of Los Angeles and Seattle. Companies scheduling calls with New Orleans tourism partners, Port of New Orleans shipping contacts, or Metairie business clients from the Pacific time zone should target calls between 11 a.m. and 5 p.m. Pacific to stay comfortably within Louisiana Central business hours.

The History of the 504 Area Code

Area code 504 is one of the original NANP codes established in 1947, and at its creation it served the entire state of Louisiana — from New Orleans on the Gulf Coast to Shreveport in the northwest and Monroe in the northeast. For more than two decades, 504 was the only area code Louisiana residents ever needed. In 1971, the growing telecommunications demand of north Louisiana led to the creation of area code 318, which split off to serve the northern half of the state including Shreveport, Monroe, and Alexandria, leaving the 504 area code to cover the southern half of Louisiana.

The most transformative period for the 504 area code came in 2001, when a single year of splits dramatically reduced its geographic footprint. Area code 225 was assigned to the Baton Rouge metro. Area code 337 was created for southwest Louisiana — the Acadiana Cajun Country and Lake Charles corridor. And area code 985 was created for the Northshore communities north of Lake Pontchartrain and the Houma-Thibodaux corridor. After these three simultaneous splits, the 504 area code was left with its current footprint — the four-parish New Orleans immediate metro: Orleans, Jefferson, St. Bernard, and Plaquemines. The 504 area code has operated without any overlay or further split since 2001.

Why a Local 504 Number Matters for Business

A 504 area code number immediately signals to contacts across southeast Louisiana that your business is embedded in the New Orleans market — not a distant national vendor calling from an unfamiliar out-of-state line. In a city built on relationships, personal trust, and a deeply rooted local culture, a familiar New Orleans prefix delivers measurable improvements in call answer rates and first-contact credibility that national or toll-free numbers simply cannot replicate.

Industries That Benefit Most from a 504 Presence

• Tourism and hospitality — New Orleans is one of the top five most visited cities in the United States. Hotels, tour operators, event planners, and vacation rental managers using a local 504 phone number connect naturally with guests, travel agents, and corporate event planners booking New Orleans experiences.
• Shipping, logistics, and port services — The Port of New Orleans is one of the most strategically important ports in the United States. Freight brokers, logistics vendors, maritime law firms, and shipping agents serving the port ecosystem build immediate credibility with a local 504 number.
• Oil, gas, and energy services — Southeast Louisiana sits at the epicenter of the US offshore oil and gas industry. Plaquemines Parish hosts critical pipeline and refinery infrastructure. A local 504 area code number signals in-market presence to energy company procurement teams operating in the Gulf of Mexico basin.
• Food, beverage, and entertainment — New Orleans is globally recognized as one of the world's great food cities. Food distributors, beverage suppliers, entertainment booking agencies, and hospitality technology vendors serving the French Quarter and metro dining scene gain significant advantages with a local 504 phone number.

Scam Calls and the 504 Area Code

The 504 area code is a frequent target for caller ID spoofing operations. Fraudsters display familiar New Orleans, Metairie, or Kenner numbers because southeast Louisiana residents — including French Quarter business owners, Metairie suburban homeowners, tourism workers, and retirees in Jefferson and St. Bernard parishes — are significantly more likely to answer a call from a recognized local Louisiana prefix than an unknown out-of-state number. The post-Hurricane Katrina rebuilding environment also created a persistent vulnerability: scammers have historically exploited recovery-related urgency in the region, and variants of those tactics continue to circulate.

Common Scam Types in the 504 Region

How to Protect Yourself

• Verify independently — hang up and call the organization back using a number from their official website, never a number provided by the caller.
• Never share financial data, Social Security numbers, or wire transfer information with any unsolicited caller.
• Report scam calls by filing an FTC fraud report.
• Register at donotcall.gov to reduce unsolicited telemarketing calls over time.

504 Area Code vs. Neighboring Area Codes

Understanding how 504 relates to surrounding Louisiana codes and neighboring state codes helps you place any Gulf Coast call at a glance.

Calls from 985 originate in the Northshore communities north of Lake Pontchartrain or the Houma-Thibodaux corridor — not New Orleans proper. Calls from 225 come from the Baton Rouge metro, roughly 80 miles northwest of New Orleans. Calls from 337 originate in the Acadiana and Lake Charles corridor. Calls from 228 cross the state line from coastal Mississippi. A 504 number is the exclusive identifier for the New Orleans immediate metro — the most recognized and culturally distinct area code in Louisiana.
