Most businesses expanding along the Gulf South overlook Mississippi's Gulf Coast — and that is precisely where the opportunity lies. The 228 area code covers three counties home to the Navy's largest surface shipbuilder, a casino industry generating over $1.6 billion annually, and a federally designated strategic seaport. This guide covers the cities served, history, time zone, scam patterns, and how to get a local number.
What Is the 228 Area Code?
The 228 area code is the sole telephone code for Mississippi's Gulf Coast, established in 1997 when demand outpaced the capacity of the original statewide 601 code. It covers three counties along the state's southernmost border and serves a metropolitan population of more than 420,000 people.

Where Does the 228 Code Cover?
The area code 228 zone spans three counties along Mississippi's southernmost edge, each with a distinct economic character. Businesses planning multi-state coverage should also learn about the 205 area code, which serves nearby Alabama markets.
Harrison County
Harrison County is the population and commercial center of the region. Gulfport is the county seat and home to the Port of Gulfport. Biloxi drives the gaming economy, with casino resorts along its waterfront and Keesler Air Force Base contributing to local employment.
Jackson County
Jackson County is the industrial engine of the Gulf Coast. Pascagoula is home to Ingalls Shipbuilding — the US Navy's single largest surface combat shipbuilder, employing approximately 11,000 workers directly. Ocean Springs offers an arts-and-dining character alongside Moss Point and Gautier.
Hancock County
Hancock County borders Louisiana and anchors the western end of the 228 zone. Bay St. Louis is the county seat, known for its historic Main Street district. Hancock County is also home to Stennis Space Center, NASA's primary rocket propulsion testing facility, employing over 5,000 skilled workers.
History of the 228 Area Code
When the North American Numbering Plan launched in 1947, Mississippi was assigned a single code — 601 — for the entire state. Growing demand from fax machines, pagers, and mobile phones through the 1990s depleted 601's supply.
The 1997 Split: 228 Created
Area code 228 was split from 601 on September 15, 1997, carving out the three southernmost Gulf Coast counties. In 1999, a second split created 662 for northern Mississippi.
No Overlay — 228 Remains Sole Code
The 228 area code has never required an overlay, so every Gulf Coast number carries the same 228 prefix. For regional business information and state resources, visit the State of Mississippi official portal.
228 Area Code Time Zone

The 228 area code zone operates in the Central Time Zone (CT): CST (UTC−6) from early November to mid-March, and CDT (UTC−5) from mid-March to early November.
Cross-Timezone Calling Guide
East Coast (ET): Eastern Time runs 1 hour ahead of Central — a 9 AM CT call arrives in New York at 10 AM ET.
West Coast (PT): Pacific Time is 2 hours behind Central. Wait until after 11 AM CT before contacting West Coast clients.
International: From the UK, dial 00 + 1 + 228 + 7-digit number; on mobile: +1-228-XXX-XXXX.
Is a 228 Area Code Call a Scam?
The area code 228 prefix is legitimate, serving real residents and businesses. Like all US codes, it is subject to caller ID spoofing by scammers who display local numbers to improve answer rates.
Health Insurance Robocalls
The most common scam involves prerecorded calls offering subsidized "government" health insurance targeting uninsured residents present in Mississippi at above-national-average rates. Legitimate insurers do not cold-call without a prior inquiry.
Auto Warranty Fraud
Robocalls claiming a vehicle warranty is expiring and demanding immediate payment are widely reported on spoofed 228 numbers. Genuine warranty departments contact customers in writing.
Medicare and Medicaid Impersonation
Scammers impersonate CMS agents requesting payment or account verification, exploiting Mississippi's older coastal population and high Medicaid enrollment. Real agencies do not initiate unsolicited calls requesting personal information.
Staying Protected
Hang up on unsolicited calls and dial the agency's published number directly. Businesses should use a STIR/SHAKEN-compliant VoIP provider to authenticate outbound caller ID and report suspicious calls at reportfraud.ftc.gov.
The 228 Economy: What Drives the Mississippi Gulf Coast
The 228 zone's economy rests on four durable pillars that make it resilient and strategically specialized. Companies managing cross-regional logistics should also understand the 281 area code, which covers the Houston shipping corridor intersecting with Mississippi Gulf Coast supply chains.
Defense and Shipbuilding
Ingalls Shipbuilding in Pascagoula builds DDG-51 destroyers and LHA assault ships under Navy contracts supporting 26,000 direct and indirect jobs. Bollinger Shipyards has secured contracts exceeding $5 billion for US Coast Guard icebreakers, projecting 3,250 additional jobs through 2030.
Gaming and Hospitality
Mississippi legalized dockside gambling in 1990, and Biloxi's waterfront corridor now generates approximately $1.6 billion in annual gaming revenue, supporting over 9,000 direct gaming jobs and 18,000 hospitality positions.
Aerospace and Research
Stennis Space Center employs more than 5,000 scientists, engineers, and federal workers across NASA, NOAA, and the NGA. Its role as NASA's primary site for Space Launch System engine testing ensures sustained federal investment through the coming decade.
Maritime Trade and Logistics
The Port of Gulfport is a primary US entry point for perishable imports from Central America and the Caribbean. Its federal strategic seaport designation brings infrastructure investment unavailable to private ports.
Why a 228 Business Number Works on the Gulf Coast

A local 228 number does work that out-of-state numbers cannot replicate. The Gulf Coast is a loyalty-driven, relationship-first community where vendors are expected to be local participants — most critical in defense procurement, casino vendor networks, and maritime logistics. NAP consistency with a 228 number drives faster local SEO results in a region far less competitive than major metro markets.
How to Get a Local 228 Business Number

1. Choose a virtual number provider with live 228 inventory and STIR/SHAKEN compliance.
2. Browse available numbers and select a format suited to the professional image expected in defense and contractor environments.
3. Configure call routing — forward to mobile, softphone, or call queue based on your team's structure.
4. Enable SMS for service reminders, booking confirmations, and logistics alerts used by hospitality and maritime clients.
5. Port an existing number if needed — LNP regulations allow transferring an existing 228 number with no service interruption.
