251 Area Code: Mobile, Alabama & Gulf Coast Complete Guide (2026)
Complete guide to 251 area code covering Mobile, Alabama, Gulf Shores, Fairhope, and Daphne. Learn about America's original Mardi Gras, the Battle of Mobile Bay, Airbus manufacturing, USS Alabama, and Hank Aaron.
The 251 area code covers southwestern Alabama, serving cities including Mobile, Daphne, Fairhope, Gulf Shores, Orange Beach, Prichard, Saraland, and Foley. Created on June 18, 2001 — the 300th area code put into service in the United States — by splitting from area code 334, it spans 9 counties and is home to approximately 662,000 people.
This is the region where America's oldest Mardi Gras celebration has been held since 1703 — fifteen years before New Orleans was even founded — where Admiral Farragut shouted "Damn the torpedoes, full speed ahead!" during the Civil War's pivotal Battle of Mobile Bay, where Airbus built the first commercial aircraft assembly line in the US, where Hank Aaron grew up before breaking Babe Ruth's home run record, and where a globally rare natural phenomenon called a Jubilee drives fish, shrimp, and crabs to shore while residents ring bells in the middle of the night. The 251 area code is where Gulf Coast grit meets 300 years of history.

251 Area Code: How Mobile Got Its Own Code
Area code 205 originally covered the entire state of Alabama as one of the original 86 NANP area codes. By the mid-1990s, growth in Birmingham and southern Alabama made a split necessary.
Created in 1995, covering all of southern Alabama from Mobile to Montgomery to Dothan. By 2000, only 155 of 800 possible central office prefixes remained — exhaustion was imminent.
Created June 18, 2001 as the 300th US area code. The Alabama PSC approved the split on October 3, 2000 in a 3-0 vote. Covers 9 counties: Mobile, Baldwin, Escambia, Monroe, Clarke, Washington, Choctaw, Conecuh, and portions of Wilcox.
America's Original Mardi Gras: Mobile Did It First
Mobile doesn't just claim to have Mardi Gras — it claims to have invented it in America. And the dates back it up. In 1703, French soldiers at the newly established Fort Louis de la Mobile held the first organized Carnival celebration in what would become the United States. Masked balls followed in 1704. The first known parade rolled in 1711, when the Société du Boeuf Gras marched 16 men pushing a cart with a giant papier-mâché cow's head through the streets.
New Orleans wasn't even founded until 1718 — fifteen years after Mobile was already celebrating. While New Orleans grew to become the globally famous Mardi Gras destination, Mobile's celebration never stopped. Today it remains one of the oldest annual public celebrations in the United States.
Mobile's Mardi Gras season features dozens of parades over a three-week period, with traditions distinct from New Orleans. The celebration is free and family-friendly. Mobile's mystic societies (similar to New Orleans' krewes) have been organizing masked balls and parades for over three centuries. The Mobile Carnival Museum on Government Street houses three centuries of costumes, regalia, and Mardi Gras history.
"Damn the Torpedoes": The Battle of Mobile Bay
On August 5, 1864, Union Admiral David Glasgow Farragut led a fleet of 18 ships into Mobile Bay to shut down one of the Confederacy's last major Gulf ports. Confederate defenses included Fort Morgan, Fort Gaines, naval mines (then called "torpedoes"), and the ironclad CSS Tennessee under Admiral Franklin Buchanan.
When the lead ironclad USS Tecumseh struck a mine and sank in minutes, the fleet hesitated. Farragut, lashed to the rigging of his flagship USS Hartford to see above the smoke, reportedly shouted the now-legendary order: "Damn the torpedoes, full speed ahead!" The fleet charged through the minefield. The Confederates surrendered Fort Gaines on August 8 and Fort Morgan on August 23.
The Union victory at Mobile Bay was one of three critical 1864 victories — alongside Atlanta and Cedar Creek — that secured Abraham Lincoln's reelection in November 1864 and ultimately ensured the war would end in Union victory.
USS Alabama Battleship Memorial Park
On the western shore of Mobile Bay sits 155 acres of military history. The centerpiece is USS Alabama (BB-60), a South Dakota-class battleship launched in 1942. The "Mighty A" earned 9 Battle Stars in World War II and led the American fleet into Tokyo Bay on September 5, 1945. Visitors can explore 12 decks of the ship.
The park also features USS Drum (SS-228), a WWII submarine credited with sinking 15 enemy ships and earning 12 battle stars, plus a collection of military aircraft, tanks, and artillery. Open 364 days a year (closed only Christmas Day), the memorial draws visitors from over 70 countries annually.
Airbus Mobile: America's First Commercial Aircraft Assembly Line
In 2012, Airbus announced it would build its first US aircraft assembly line at the Mobile Aeroplex at Brookley — the former Brookley Air Force Base. Production began in July 2015, and the first completed aircraft, an A321, was delivered to JetBlue on April 25, 2016. It was the first new large commercial aircraft manufacturer established in the US in four decades.
Today the facility operates 3 final assembly lines — two for the A320 family and one for the A220 — with over $1 billion invested and more than 600 aircraft delivered. The second A320 line opened in October 2025. Employment exceeds 2,000 workers and is growing to over 3,000 with a 1,000-job expansion.
Mobile is now the 4th largest commercial aviation manufacturing location in the world. Aerospace is the city's fastest-growing industry sector, with 56% growth in five years. Combined with Austal USA — a shipbuilder on Blakeley Island employing 4,000+ workers building US Navy vessels including Independence-class Littoral Combat Ships — Mobile has transformed into a manufacturing powerhouse.
Hank Aaron: Mobile's Greatest Athlete
Henry "Hank" Aaron was born on February 5, 1934, in a section of Mobile called "Down the Bay." At Mobile's Central High School, he was a classmate of another future Hall of Famer — Willie McCovey. Aaron went on to break Babe Ruth's record with 755 career home runs, a record that stood from 1974 to 2007.
Mobile honors its greatest athlete with Hank Aaron Stadium (the minor league ballpark), the Hank Aaron Childhood Home and Museum, and a statue at the stadium entrance. Mobile has produced more Major League Baseball Hall of Famers per capita than almost any other American city, including Satchel Paige, Willie McCovey, Ozzie Smith, and Billy Williams.
The Mobile Bay Jubilee: A Phenomenon Found Nowhere Else
Mobile Bay is one of only two known places in the world — the other being Tokyo Bay, Japan — where a natural phenomenon called a Jubilee regularly occurs. During summer months (June through September, most commonly August), oxygen depletion in deep water drives fish, shrimp, crabs, and eels to swarm into the shallows along the eastern shore.
Jubilees typically happen before sunrise. When someone spots one beginning, residents ring bells and shout to alert neighbors, who rush to the shore with washtubs, nets, and gigs to collect the bounty. Over an 11-year study, researchers documented 37 jubilees. The tradition is so ingrained in Eastern Shore culture that Daphne calls itself the "Jubilee City."
Baldwin County: Alabama's Fastest-Growing County
While Mobile city has seen modest population decline, Baldwin County on the eastern shore of Mobile Bay is exploding. It is the fastest-growing county in Alabama and the 6th fastest-growing metropolitan area in the entire nation, with 66.3% population growth over 20 years. Ninety-seven percent of that growth comes from incoming migration, especially retirees aged 65+.
Fairhope (pop. ~22,500) was founded in 1894 as a utopian single-tax colony by 28 followers of economist Henry George. The Fairhope Single-Tax Corporation still operates today with 1,800 leaseholds covering 4,000+ acres — residents lease land on 99-year renewable agreements rather than owning it. Today it's known as an arts haven.
Gulf Shores and Orange Beach drew 6.5 million visitors in 2023, who spent $6.7 billion and supported 55,000 tourism-related jobs. The beaches have over 14,000 short-term vacation rental units. Tourism is Baldwin County's number one industry.
Port of Mobile: 300 Years of Maritime Commerce
The Port of Mobile has operated continuously for over 300 years, making it one of the oldest port locations in the United States. Formally established under the Alabama State Port Authority in 1928, it handles 55+ million tons of cargo annually and has been ranked as high as the 9th largest US port by tonnage.
The port's economic impact on Alabama: $98.3 billion (2022), supporting 351,359 jobs — that's 1 out of every 7 jobs in the state. It is the largest break-bulk forest products port in the US, and McDuffie Terminal is one of the largest coal terminals in the country.
