228 Area Code: Biloxi & Mississippi Gulf Coast — Cities, History & How to Get One

Introduction

Few stretches of the American South carry the same mix of natural beauty and economic muscle as the Mississippi Gulf Coast. From the casino resorts lining Biloxi's beachfront to the naval shipyards in Pascagoula and the busy cargo docks of Gulfport, the 228 area code ties together one of the most dynamic coastal regions in the country.

This guide goes beyond the basics. You will find the exact counties and cities the code covers, the time zone, the full story of its 1997 creation, how to dial correctly, and the quickest way to secure your own local 228 phone number — whether you live on the Gulf Coast or target it from across the country.

What Is the 228 Area Code?

The 228 area code is a North American Numbering Plan (NANP) telephone prefix assigned exclusively to the three southernmost counties of Mississippi — Harrison, Jackson, and Hancock — all of which sit directly on the Gulf of Mexico. It is one of three active codes serving Mississippi, alongside 601 (central and southern inland) and 769 (the 601 overlay).

Every phone number in the Gulf Coast metro begins with 228, making it the shared calling identity for roughly 400,000 residents. From Biloxi's waterfront casino strip to Ingalls Shipbuilding's vast yards in Pascagoula, this prefix connects the entire coastal zone. Here is the code at a glance:

Where Is Area Code 228 Located?

The region hugs the Gulf of Mexico coastline in the far south of Mississippi, stretching roughly 80 miles from the Louisiana border in the west to the Alabama border in the east. Coverage boundaries follow county lines, so both dense urban cores and rural communities share the same 228 prefix. Just across the state line to the east, Mobile and its suburbs dial on the 251 area code, part of the same Gulf Coast corridor.

Counties in the 228 Coverage Zone

• Harrison County — the urban core, home to Biloxi, Gulfport, Long Beach, and Pass Christian
• Jackson County — Pascagoula, Ocean Springs, Gautier, and Moss Point; the industrial anchor of the region
• Hancock County — Bay St. Louis, Waveland, and Diamondhead; the westernmost point in the coverage zone, bordering Louisiana

Major Cities in Area Code 228

Biloxi and Gulfport dominate the region, but a string of distinct communities each add their own character and economic weight:

Biloxi is also home to Keesler Air Force Base, one of the largest Air Force training installations in the United States — adding a significant military population to the mix and giving the 228 zone a uniquely diverse demographic profile.

Time Zone for the 228 Region

The entire three-county Gulf Coast sits in the Central Time Zone — the same zone as Chicago, Dallas, and New Orleans. That means Central Standard Time (CST, UTC−6) from early November to mid-March, then Central Daylight Time (CDT, UTC−5) while daylight saving time is active.

Calling the Gulf Coast from New York (Eastern Time)? The region is one hour behind. From Los Angeles (Pacific Time), the Gulf Coast is two hours ahead. Standard local business hours run 9 AM to 5 PM Central — keep that in mind when scheduling calls across time zones.

History of Area Code 228

Before 1997, the entire state of Mississippi operated under a single telephone prefix: 601. From Tupelo in the north to Biloxi on the coast, every Mississippi phone number began with those three digits. Through the late 1980s and early 1990s, the Gulf Coast experienced rapid development — casino gambling was legalized in 1990, triggering a construction boom that brought new hotels, businesses, and residents.

At the same time, mobile phones, fax machines, and internet dial-up connections were multiplying the demand for new phone numbers. The 601 number pool began running short on available combinations, and regulators needed to act.

The 1997 Split from Area Code 601

On March 22, 1997, the Mississippi Public Service Commission and the North American Numbering Plan Administrator (NANPA) executed a geographic split. The 601 code retained coverage of central and southern inland Mississippi — including Jackson, the state capital. The three Gulf Coast counties received the newly created 228 area code.

The transition was significant for Gulf Coast businesses, which had to update signage, directories, and marketing materials. Within a few years, however, 228 became a point of regional pride — an identifier that distinguished the coastal strip from the rest of the state. Then came Hurricane Katrina in August 2005, which devastated the Gulf Coast. The subsequent rebuild brought new residents, new businesses, and renewed investment — all of which reinforced the 228 code's role as the calling identity of a resilient and growing region.

How to Dial a 228 Phone Number

The FCC's nationwide 10-digit dialing mandate means every call — local or long-distance — now requires the full prefix plus the seven-digit number. Here is the correct format for each call type:

Industries & Economy in the 228 Region

The Gulf Coast counties served by the 228 code run on one of the most economically diverse engines in the American South. Local numbers power communication across every major sector:

• Gaming & tourism: Biloxi's casino strip draws millions of visitors each year, making tourism one of the region's top revenue drivers and employing tens of thousands of workers.
• Military: Keesler Air Force Base in Biloxi is one of the largest Air Force technical training centers in the country, supporting a sizable active-duty, civilian, and contractor workforce.
• Shipbuilding & defense: Ingalls Shipbuilding in Pascagoula is one of the nation's largest employers of shipbuilders, constructing destroyers and amphibious ships for the U.S. Navy.
• Port logistics: The Port of Gulfport handles millions of tons of cargo annually — bananas, hardwood products, and containerized freight — making it a critical link in Gulf Coast supply chains.
• Healthcare: Memorial Hospital at Gulfport and Singing River Health System in Pascagoula are among the region's largest employers, generating significant daily call volume across their networks.
• Higher education: The University of Southern Mississippi's Gulf Park campus in Long Beach and William Carey University in Biloxi add an educational dimension to the local workforce.

Whether you run a law firm, a logistics company, or a remote sales team targeting Mississippi clients, a local 228 number is the credibility signal that gets your calls answered. Pair it with call forwarding, custom caller ID, and two-way SMS for a full local phone presence — regardless of where you actually sit.

Why a Gulf Coast Number Helps Your Business

A local area code is one of the most underrated assets a business can own. For companies serving the Mississippi Gulf Coast, a 228 phone number delivers measurable advantages:

• Higher answer rates: People are far more likely to pick up a call from a recognizable 228 number than from an unfamiliar out-of-state or toll-free line.
• Instant local credibility: A Gulf Coast prefix tells customers you are part of their community — not a distant call center they have never heard of.
• Stronger local SEO: A consistent 228 number across your Google Business Profile, website, and directories reinforces your local-pack rankings in Biloxi and Gulfport searches.
• Better marketing ROI: Local numbers on billboards, digital ads, and social profiles convert better because they feel familiar and relevant to the reader.
• Privacy for your personal line: Advertise a dedicated business number while keeping your real cell unlisted and protected from unwanted calls.
• Military & government outreach: In a region with a large military presence at Keesler and a significant government contractor base, a local prefix signals legitimacy and accessibility.

National brands use 228 numbers to enter the Gulf Coast market without a physical office, while local businesses use them to look established and reachable — much like companies build trust with the 985 area code across coastal Louisiana.

Are 228 Calls a Scam? Spotting & Avoiding Fraud

No — 228 is the legitimate calling prefix for the Mississippi Gulf Coast. That said, scammers can spoof any area code, including 228, to make a call appear local. The number displayed on your screen is never proof of who is actually calling.

Protect yourself with a few straightforward habits:

• Never share sensitive details — Social Security numbers, bank account information, or one-time passcodes — with anyone who called you unexpectedly.
• Verify independently. If a caller claims to be your utility company or a government agency, hang up and call the official number from their website or your bill.
• Be wary of urgency. Threats, deadlines, and "act immediately" pressure are classic fraud tactics designed to stop rational thinking.
• Use call-blocking tools like Hiya, Truecaller, or Nomorobo, and register your number with the National Do Not Call Registry.
• Report fraud to the FTC to help protect others in the Gulf Coast region.

Virtual numbers from certified providers are real, NANPA-assigned lines routed through carrier-grade infrastructure that passes STIR/SHAKEN verification — so your outbound calls display a clean, trustworthy caller ID, never a "Spam Likely" warning.
