Have you ever wondered how phone numbers are structured? In North America, it all falls under the North American Numbering Plan (NANP). This system divides geographical regions into distinct numbering plan areas, each identified by a unique three-digit area code. These area codes are assigned and managed to ensure that everyone has a unique phone number.
The 361 area code serves a specific slice of Texas. If you’re calling Corpus Christi, Victoria, or other communities in that region, you’re dialing into the 361. It’s a key identifier for that part of the state.
This article will cover the 361 area code’s story, including its history, the geography it covers, the people who live there, and potential changes coming in the future.
The History of the 361 Area Code
The 361 area code didn’t always exist. It was created on February 13, 1999, from a split of the 512 area code. (Source: Texas Public Utility Commission records). The growing population in South Texas, along with the increasing use of cell phones and fax machines, meant the 512 area code was running out of available numbers. To avoid that, the Public Utility Commission of Texas decided to create a new area code, 361, to serve the southern portion of the region.
Initially, the 361 area code covered a large swath of South Texas, including major cities like Corpus Christi, Victoria, and Kingsville. It encompassed several counties, including Nueces, Victoria, Kleberg, and Refugio, among others. This new area code allowed for a greater supply of phone numbers to meet the demands of a rapidly expanding population and economy.
Since its creation, the geographic boundaries of the 361 area code have remained largely unchanged. There haven’t been any significant reassignments or splits. It continues to serve the same general region of South Texas, providing a crucial telecommunications link for the area’s residents and businesses.

Demographics of the 361 Area Code Region
Who lives in the 361 area code? Here’s a look at the population, demographics, and socioeconomic indicators that define the region.
Population Overview
The 361 area code serves over 600,000 people in South Texas. That’s a significant population, but it’s smaller than the population served by some of the larger metro area codes in Texas, such as 214/469 (Dallas) or 713/281/832/346 (Houston). The population density in the 361 area code is around 75 people per square mile, which is lower than the Texas average but higher than the national average.
Demographic Breakdown (2020 Census data)
The 361 area code is home to a diverse population. Here’s a breakdown, based on the most recent census data:
- Race and Ethnicity: Approximately 70% of the population identifies as Hispanic or Latino, 25% as White (non-Hispanic), 4% as Black or African American, and 1% as Asian.
- Age and Gender: The median age in the 361 area code is around 35 years old. The gender distribution is fairly even, with a slight majority of females.
- Household Characteristics: The average household size is around 3 people, and the average family size is slightly larger. There are roughly 220,000 housing units in the region, the vast majority of which are occupied.
Socioeconomic Indicators
Understanding the economic and educational landscape provides further insights into the 361 area code region.
- Income Levels: The median household income in the 361 area code is lower than both the state and national averages. Per capita income also lags behind state and national figures.
- Education Levels: Educational attainment in the region is mixed. While a significant percentage of the population has a high school diploma, the percentage of residents with a bachelor’s degree or higher is lower than the state and national averages.
These demographic and socioeconomic factors paint a picture of a diverse region with a strong Hispanic presence, a relatively young population, and economic indicators that suggest opportunities for growth and development.
Time Zone and Location
The 361 area code is located in the Central Time Zone (CT), which is GMT -06:00 during standard time.
Like most of the United States, the 361 area code observes Daylight Saving Time (DST). This means that during the warmer months, clocks are shifted forward one hour. DST typically begins on the second Sunday in March and ends on the first Sunday in November.
Geographically, the 361 area code covers a region in South Texas, including areas along the beautiful Gulf Coast. So, if you get a call from a 361 number, chances are it’s coming from somewhere near the Texas shoreline!
Prefix assignment and numbering resources
Like any area code, the 361 area code is carefully managed to ensure that there are enough phone numbers to go around. Here’s a little more about how that works.
Prefix assignment statistics
Each area code contains numerous “prefixes,” which are the first three digits after the area code in a phone number. So, in the phone number 361-555-1212, “555” is the prefix.
Across the 361 area code, roughly [insert percentage]% of prefixes are currently assigned. Some prefixes are active, while others are inactive. Prefixes can be inactive for a variety of reasons, such as a service provider going out of business or returning the prefix to the pool for later use.
Usage type breakdown
A certain number of prefixes within the 361 area code are assigned to landlines, while others are assigned to wireless or mobile phones. Across the U.S., the trend is toward increased wireless usage and decreased landline usage, as more people opt for cell phones over traditional home phones.
Still other prefixes may be assigned to VoIP (Voice over Internet Protocol) services or other specialized services.
Numbering administration
The North American Numbering Plan Administrator (NANPA) manages area codes and prefixes throughout the U.S., Canada, and other parts of North America. NANPA is responsible for assigning and allocating numbering resources to ensure that phone numbers are available when and where they’re needed.
Area Code Overlays and Future Planning
Currently, the 361 area code doesn’t have any overlays. An “area code overlay” is when a new area code is introduced to the same geographic region as an existing one. This usually happens when the original area code is running out of available phone numbers. Instead of splitting the area, which would require some customers to change their numbers, an overlay adds a new area code, and new phone numbers are assigned using that new code.
The 361 area code has never had an overlay. So far, the existing number pool has been sufficient to meet demand.
Right now, there’s no official “relief planning” underway for the 361 area code. Relief planning becomes necessary when the supply of available phone numbers gets critically low. Factors like population growth and the increasing use of cell phones and other devices can contribute to “number exhaustion.”
One thing that impacts area code planning is “number portability.” This means that people can keep their existing phone numbers when they switch phone service providers or move to a new location. This reduces the need for new numbers, as people aren’t constantly getting new phone numbers assigned to them when they switch services or move.
What other area codes are nearby?
The 361 area code is neighbors with several others in Texas. To the north, you’ll find area code 254, covering a large area of central Texas, including Killeen and Waco. To the northeast is area code 979, which serves the Brazos Valley and cities like College Station. Moving west, area code 830 covers a wide swath of south-central Texas, including the Texas Hill Country. Finally, south of 361 is area code 956, encompassing the Rio Grande Valley along the border with Mexico.
Major telecommunications companies in the 361 area include providers offering both traditional landline service and wireless options. You’ll find names like AT&T, Verizon, and T-Mobile providing service in the region, along with smaller local providers.
Like everywhere else, the way people in the 361 area code use phones is changing. Technologies like VoIP (Voice over Internet Protocol) and mobile broadband are becoming increasingly popular. These technologies give people more flexibility in how they communicate, allowing them to make calls and access the internet from anywhere with a connection. This has changed how people use traditional phone numbers, relying more on data and internet-based communication methods.
Conclusion
The 361 area code covers the Gulf Coast region of Texas, including Corpus Christi, Victoria, and Kingsville.
In today’s world of smartphones, VOIP, and sophisticated telecommunications, it’s easy to forget that area codes are still relevant. They help us pinpoint geographic locations and connect with people across the country.
As technology advances, area codes and numbering resources will likely continue to evolve. But for now, the 361 area code remains a vital part of the Texas telecommunications landscape, connecting people and businesses along the beautiful Gulf Coast.
