Geographic Coverage Map

The 361 area code region stretches along approximately 150 miles of the Texas Gulf Coast, from Matagorda Bay in the northeast to areas near the King Ranch in the southwest. The coverage area extends inland roughly 60 to 80 miles from the coast, encompassing coastal prairies, agricultural lands, and portions of the South Texas Plains. The region is bordered by the Gulf of Mexico to the east and southeast, with neighboring area codes serving adjacent regions of Texas. This strategic coastal location makes the 361 area code region an important hub for shipping, fishing, tourism, and energy production.

Time Zone Information

The entire 361 area code region operates in the Central Time Zone, which is six hours behind Coordinated Universal Time (UTC-6) during standard time and five hours behind (UTC-5) during daylight saving time. Daylight saving time is observed from the second Sunday in March through the first Sunday in November each year. This means residents and businesses in Corpus Christi and surrounding areas set their clocks forward one hour in spring and back one hour in fall. When coordinating calls or meetings with people in other time zones, it’s helpful to use a time comparison tool to ensure accurate scheduling across different regions.

History of 361 Area Code

When Was 361 Created?

The 361 area code was created on February 13, 1999, as part of a geographic split from the 512 area code. Prior to 1999, the entire Coastal Bend region, along with Austin and much of Central Texas, shared the 512 area code. As the population grew throughout the 1980s and 1990s, particularly in Austin and the surrounding metropolitan areas, the demand for telephone numbers increased dramatically. The proliferation of cell phones, pager services, fax machines, and additional business lines exhausted the available number combinations in the 512 area code.

To address this shortage, the North American Numbering Plan Administrator (NANPA) and telecommunications regulators determined that a geographic split was necessary. The solution divided the 512 territory, with the Austin metropolitan area and surrounding counties retaining the 512 area code, while the Coastal Bend region and Victoria area were assigned the new 361 area code. This split ensured an adequate supply of telephone numbers for both regions while maintaining geographic logic in area code assignments.

Area Code Changes and Overlays

Since its establishment in 1999, the 361 area code has not undergone any overlay implementations. An overlay area code is a second area code assigned to the same geographic region, requiring ten-digit dialing for all calls including local ones. As of 2026, the 361 area code continues to serve the Coastal Bend region exclusively without overlays, and residents can still use seven-digit dialing for local calls within the same area code in most situations, though ten-digit dialing has become increasingly common as a standard practice.

The region’s relatively stable population growth compared to major metropolitan areas like Houston, Dallas, or Austin has meant that the supply of available telephone numbers within the 361 area code remains sufficient. However, telecommunications officials continue to monitor number usage patterns, and an overlay could be implemented in the future if demand increases significantly due to population growth or increased telecommunication device usage.

How to Call 361 Area Code

Dialing Within the Area Code

When making local calls within the 361 area code region, you can typically dial just the seven-digit telephone number (XXX-XXXX) without including the area code. However, many modern phone systems and mobile devices automatically default to ten-digit dialing (361-XXX-XXXX) even for local calls. Some telecommunications providers have implemented mandatory ten-digit dialing in preparation for potential future overlays, so it’s advisable to use the full ten-digit format to ensure your call connects properly.

Dialing From Other Area Codes

When calling the 361 area code from anywhere else in the United States, Canada, or other North American Numbering Plan countries, you must dial 1 followed by the area code and seven-digit phone number: 1-361-XXX-XXXX. The “1” is the long-distance prefix required for calls outside your local area code. Most mobile phones automatically add this prefix when you dial a ten-digit number, but landline users need to include it manually for the call to complete successfully.

International Dialing

To call a 361 area code number from outside the United States, you must use the international dialing format. First, dial your country’s international access code (often 00 or 011, depending on your location), then dial the United States country code (1), followed by the area code and phone number: +1-361-XXX-XXXX. For example, from the United Kingdom, you would dial 00-1-361-XXX-XXXX, while from many other countries, you would dial the plus sign (+) which your phone automatically converts to the appropriate international access code, followed by 1-361-XXX-XXXX.
