361 Area Code: Location, Cities, History & How to Get One

Along the sun-soaked shores of the Texas Gulf Coast, where the Coastal Bend curves gently toward the Gulf of Mexico and oil tankers line the horizon, sits one of the most economically dynamic regions in the American South. This is the territory of the 361 area code — a region anchored by Corpus Christi, home to the third-largest port in the United States by tonnage, and spanning 64 cities across 22 counties of South Texas. Whether you are a business looking to establish local credibility in the energy capital of the Gulf Coast or simply trying to understand who is calling you from a 361 number, this guide covers everything you need to know about area code 361.

What Is the 361 Area Code and Where Is It?

The 361 area code is a telephone area code in the North American Numbering Plan (NANP) serving the Coastal Bend region and the Victoria Crossroads of South Texas. It covers a broad swath of the Texas coastline — stretching from the barrier islands of Mustang Island and Padre Island in the southeast to the agricultural heartland around Victoria and Cuero in the north, and as far west as Laredo's eastern neighbors along the Rio Grande.

The region operates entirely within the Central Time Zone (CT) — Central Standard Time (CST, UTC−6) in winter, and Central Daylight Time (CDT, UTC−5) during daylight saving time from mid-March through early November.

Geographic Overview

The 361 area code location encompasses 22 counties and 64 cities across South Texas. Key geographic identifiers include:

• The Coastal Bend — the arc of coastline from Rockport south through Corpus Christi and Padre Island to the lower Gulf Coast.
• The Victoria Crossroads — the inland commercial hub around Victoria, serving as the gateway between Houston, San Antonio, and the coast.
• The South Texas Plains — a vast, sparsely populated region extending toward the Mexican border, dotted with ranching and oil-producing communities.

Major Cities in the 361 Area Code

The following are the most significant communities served by the area code 361:

• Corpus Christi: The region's largest city, with a population of approximately 317,000 and the cultural, commercial, and industrial hub of the 361 area code. Home to the Port of Corpus Christi, Naval Air Station Corpus Christi, and a thriving petrochemical industry.
• Victoria: With roughly 68,000 residents, Victoria is the second-largest city in the 361 region and serves as an agricultural and industrial crossroads for South Texas. It sits at the intersection of US-77 and US-87, making it a key distribution hub.
• Kingsville: Home to Texas A&M University–Kingsville and the Naval Air Station Kingsville, this city of approximately 25,000 has a strong military and educational presence.
• Alice: Known as the "Hub of South Texas," Alice is a city of roughly 20,000 that serves as a regional service center for the surrounding oil-producing counties of Jim Wells and Duval.
• Rockport: A coastal gem of approximately 19,000 people, Rockport is celebrated for its fishing, birding, and arts community — one of the top birding destinations in North America and a gateway to Aransas National Wildlife Refuge.
• Beeville: The county seat of Bee County and home to Coastal Bend College, Beeville serves the ranching and agricultural communities of the interior.
• Portland: A fast-growing community of 22,000 on the north shore of Corpus Christi Bay, Portland is one of the most rapidly developing cities in the 361 region.
• Port Aransas: Located on Mustang Island, Port Aransas is a popular beach and fishing destination that draws tourists from across Texas and beyond.
• Port Lavaca: The county seat of Calhoun County, situated on Lavaca Bay, with deep roots in commercial fishing and petrochemical processing.
• Ingleside: A city on the Coastal Bend with significant industrial infrastructure, including liquid natural gas (LNG) export facilities on the ship channel.

Other communities in the 361 area code include Aransas Pass, Robstown, Cuero, Goliad, Edna, Hallettsville, Yoakum, Falfurrias, George West, Three Rivers, Hebbronville, Kenedy, and many more across the South Texas plains.

The History of the 361 Area Code

Like most area codes in Texas, the story of area code 361 is a story of growth. Through the 1990s, Texas experienced one of the most dramatic population and economic expansions in modern American history — driven by energy, technology, immigration, and a business-friendly tax environment that attracted companies from across the country. That growth put enormous pressure on the telephone numbering system.

From 512 to 361: The 1999 Split

For decades, South Texas was served by area code 512, which had been assigned to the region in the original 1947 North American Numbering Plan. By the late 1990s, that single area code was responsible for covering everything from Austin to the Gulf Coast — a territory so large and so rapidly growing that it was running out of available number combinations.

To relieve the pressure, regulators created a new area code dedicated exclusively to the Coastal Bend and South Texas. On February 13, 1999, area code 361 went into service, carving out the Corpus Christi area, the Victoria Crossroads, and the surrounding rural counties from the 512 territory. Austin and Central Texas retained the 512 prefix, while South Texas moved to its own dedicated identifier — one that quickly became a source of regional pride for residents of the Coastal Bend. The Dallas metro, served by the 214 area code, similarly drove Texas's early area code splits.

The 2021 Dialing Change

In October 2021, the way people dial within the 361 area code changed permanently. Before that date, local calls within the same area code could be completed with just 7 digits. However, the FCC designated 988 as the national three-digit dialing code for the Suicide and Crisis Lifeline. Because 988 had previously been used as a standard central office exchange prefix within the 361 area, a conflict existed — dialing 988-XXXX locally would now route to the crisis line instead.

To resolve this, the 361 area code transitioned to mandatory 10-digit dialing by October 24, 2021. Today, all calls within the region — whether across town or across the county — must include the full area code: 361-XXX-XXXX.

Virtual Phone vs. Traditional Landline for 361 Numbers

Once you have decided to establish a presence in South Texas with a 361 phone number, you face a choice between two fundamentally different types of phone service. For most businesses, the decision is clear.

Flexibility and Mobility

• Traditional Landline: Ties your 361 number to a physical address and a desk phone. If you are not sitting at that desk, you miss the call. Entirely impractical for remote teams, traveling sales staff, or businesses based outside Texas.
• Virtual Number: Lives in the cloud. Your 361 number rings on your smartphone, laptop, or tablet wherever you are — in Corpus Christi, in New York, or anywhere in the world with an internet connection.

Cost Efficiency

• Traditional Landline: Requires installation, physical hardware, and long-term service contracts. Adding a second line means doubling the infrastructure and cost.
• Virtual Number: No hardware. No installation fees. No long-term contracts. A low, predictable monthly subscription gives your business a professional South Texas number from day one.

Professional Features

• Traditional Landline: Basic calling and voicemail. Advanced features like call recording or an auto-attendant typically cost significantly more and require additional hardware.
• Virtual Number: Includes powerful features as standard — call forwarding, IVR menus, voicemail-to-email transcription, call recording, two-way SMS, and detailed analytics — at no extra hardware cost.

Why Your Business Needs a 361 Area Code Number

In an era when 80% of Americans ignore calls from numbers they do not recognize, a local area code is one of the most powerful tools in your business communication arsenal. A 361 area code number tells South Texas customers immediately that you are one of them — a local business invested in their community.

Build Instant Local Trust

When a Corpus Christi resident or a Victoria business owner sees a 361 prefix on their caller ID, they recognize it as local. That familiarity breaks down barriers before the conversation even starts. Calls from local numbers achieve answer rates two to four times higher than calls from unfamiliar or out-of-state numbers — a critical advantage for sales teams, customer service operations, and outreach campaigns in the South Texas market.

Reach a Growing South Texas Market

The 361 area code serves an estimated population of over 650,000 people across its 22-county coverage zone. The region has a median household income of approximately $66,967 and a predominantly Hispanic demographic (approximately 62% of Corpus Christi's population identifies as Hispanic or Latino), making it one of the most culturally distinct and commercially underserved markets in the United States. Businesses that establish authentic local presence here have a significant competitive advantage, much like companies targeting East Texas via the 903 area code.

Target the Energy and Industrial Sector

The 361 area code region is the energy hub of the Gulf Coast. Companies serving the oil and gas, petrochemical, LNG, and maritime industries will find that a local South Texas number opens doors that a generic toll-free or out-of-state number simply cannot. Port procurement officers, refinery managers, and logistics coordinators in Corpus Christi and Ingleside are more likely to engage with a vendor who shows a 361 area code on the caller ID.

Establish Presence Without a Physical Office

A virtual 361 phone number lets any business — headquartered in Dallas, Chicago, or anywhere globally — establish an immediate and credible local presence in South Texas. You gain all the advantages of a local number without leasing office space in Corpus Christi.

The Economy Behind the 361 Area Code

Understanding the economic landscape of the 361 area code region is essential for any business considering a presence here. This is not a retirement destination or a suburban bedroom community — it is a working region built on energy, trade, agriculture, and military might.

The Port of Corpus Christi: A Global Energy Gateway

The single most important economic engine in the 361 area code region is the Port of Corpus Christi — the third-largest port in the United States by total waterborne tonnage. The port handled a record-breaking 206.5 million tons of cargo in 2024, marking the seventh consecutive record year and a 1.7% increase over the previous high set in 2023. Total trade through the port has surged by an extraordinary 487% between 2016 and 2024.

Trade through the Port of Corpus Christi in 2024 contributed $113 billion to Texas's GDP and supported 864,000 jobs across the state. The port is the leading US exporter of crude oil and a major hub for LNG exports — two commodities driving the global energy transition. For businesses in logistics, freight, energy services, maritime law, and international trade, the 361 region is simply one of the most important commercial addresses in North America.

Energy, Oil, and Petrochemicals

South Texas sits atop some of the most productive oil and gas reserves in the world. The Eagle Ford Shale, which stretches through several 361 counties, has been one of the most actively developed shale formations in the United States. Corpus Christi is home to multiple major refineries and petrochemical facilities, including operations by Valero Energy, Flint Hills Resources, and MPLX. Companies supplying products and services to the energy sector will find a deep, commercially active customer base throughout the 361 area code, one of thousands of prefixes tracked in the NANPA database.

Military and Federal Presence

The 361 region has a significant and stable federal employment base. Naval Air Station Corpus Christi is one of the largest naval air training facilities in the world, training military aviators for the US Navy, Marine Corps, Coast Guard, and allied foreign militaries. Corpus Christi Army Depot is the US Army's largest aviation maintenance facility, performing overhaul and repair of military helicopters. Together, these installations employ thousands of military and civilian workers and generate enormous demand for local goods and services.

Healthcare, Education, and Retail

CHRISTUS Spohn Health System is one of the largest employers in the 361 region, operating multiple hospitals and clinics across the Coastal Bend. Texas A&M University–Corpus Christi, Texas A&M University–Kingsville, and Del Mar College collectively educate tens of thousands of students and anchor the region's growing knowledge economy. Retail and hospitality businesses along the Gulf Coast benefit from strong seasonal tourism, with attractions including the Texas State Aquarium, the USS Lexington Museum, Padre Island National Seashore, and Mustang Island State Park. East Texas forms the neighboring region to the northeast.

361 Virtual Number vs. Traditional Landline: A Comparison

How to Dial a 361 Area Code Number

Calling a 361 number is straightforward. Here is the correct format depending on where you are calling from:

From Within the United States or Canada

Dial the full 10-digit number: 361-XXX-XXXX. Since October 24, 2021, 7-digit local dialing is no longer accepted within the 361 area. Always include the area code, even when calling a neighbor in the same Corpus Christi neighborhood.

From Outside the United States

Dial your country's international exit code, followed by the US country code and the full number: +1-361-XXX-XXXX. On most smartphones, this is entered as +1 361 XXX XXXX using the + prefix for international calls.

Neighboring Area Codes

Is the 361 Area Code a Scam?

The 361 area code is entirely legitimate. It is a standard geographic area code assigned by the North American Numbering Plan Administration (NANPA) and has been in continuous, lawful operation since February 1999. Every resident and business in South Texas who has a local phone number uses the 361 prefix — it is as real as any other area code in the United States.

That said, scammers can and do use any area code — including 361 — through a technique called "neighbor spoofing." This is when a fraudulent caller uses software to make their call appear on your caller ID with a familiar local prefix, increasing the likelihood that you will answer. The 361 area code itself is not the problem; the spoofing technology is.

How to Protect Yourself from Spoofed 361 Calls

• Never share personal, financial, or account information with an unsolicited caller, regardless of what area code is displayed.
• Hang up and call back using the verified official number from the company's website if a caller claims to be from your bank, utility provider, or a government agency.
• Be skeptical of urgency. Legitimate organizations rarely demand immediate payment or personal information over the phone under threat of consequences.
• Use a call-screening app such as Hiya, Truecaller, or your carrier's built-in spam detection to automatically flag suspicious callers.
• Register with the Do Not Call Registry at donotcall.gov to reduce unsolicited marketing calls.
• Report scam calls to the FTC at reportfraud.ftc.gov — this helps regulators identify patterns and take action against fraudsters.

For businesses using a 361 number through Callmama, all outbound calls are authenticated using STIR/SHAKEN protocols — the industry-standard verification system that proves your calls are genuinely from your registered number, ensuring they are never mislabeled as "Scam Likely" on your customers' caller ID.
